The Southwestern Peninsula of Trinidad

One of the most beautiful places I have ever been to is the Southwestern Peninsula of Trinidad. I try my best to go every year. It is a lovely pristine environment. I have a place in my heart for Los Blanquizales. A lot of people call it the Great Icacos Lagoon.
Cedros is the name of the area. There is no specific town calledCedros. The Spanish arrived and saw Cedar trees hence the name Cedros which is Spanish for Cedars. The Native Peoples called fat pork "icaco". This is where the Spanish got the name Icacos from.
I had gone to Columbus Bay for the first time in the early 1990s. My dad was still alive and drove us down there. I saw the stacks in the water. Today has three but I feel as though I had seen four. In those times, I didn't know about journalling and documenting so I rely on memory which is not always a good thing. I prefer document and photograph.
I wanted to visit Cedros so in 2010 I had planned a visit with my Form 5 form class. They were a great bunch. We went with a maxi taxi all the way to Columbus Bay. We went Icacos after. I had so much fun. I was amazed when I saw Los Blanquizales, that was my first visit to Icacos.
At Icacos, there were fallen coconut trees, a sign of the coastal erosion happening. The road was eroded as well. There were lots of verveine plants. We got back to school in time for 2:30 p.m.
From San Fernando to Cedros, the journey is about 2 hours. Yes a very long drive. I usually pass through the Creek, Oropuche, Rousillac, La Brea, Point Fortin, Cap de Ville, Granville. That route is actually faster. In 2018, I passed through Debe, Penal, Siparia, Santa Flora, Palo Seco, Erin, Buenos Ayres, Cap de Ville. That way was pretty lengthy but has some nice Historical sites on the way.
Cedros has so much biodiversity. I have seen huge stinging nettles, Malachite butterfly, Flambeaux, Red Peacocks, Nymphea, Mangrove, Caracaras, Corbeaux, Bats, an area with those lovely purple flowers whose seeds explode in water and an abundance of trees.
The Ste. Marie Road where the Health Centre is located has a lot of trees and bushes however near the L'Envieusse beach, rapid deforestation has taken place. A bad idea because the beaches down there are basically sand and mud, hence easily eroded. I believe Ste. Marie Road leads to Islote Bay. L'Envieusse beach has Mangrove, Iron Pyrite (fool's gold) and a shipwreck. There is a structure made of ballast bricks that most likely came from Scotland in the 1800s. When you journey along Ste. Marie Road, there is Ste. Marie Extension on the left. This takes you to Galfa proper. There is fool's gold, sandstone cliffs and mud that smells of methane gas. The area was once mined for oil and natural gas.
Along Ste. Marie road, there is a road on the right that takes you to Green Hill where the underground WWII bunker is. Further down on the right has the road that takes you to the Balka Devi Mandir and the mud volcano. Further down, the road splits, if you keep left, you end up at a private beach, Beaulieu and if you take right, you end up at L'Envieusse. There is an old house, said to be haunted and next to it is the Galfa Graves. One person died in 1813, the other in 1818.
At the Los Blanquizales marshes, there are so many birds! I have seen Herons a lot but one time I saw this huge black and white raptor. It was far off but the breast was white and its wings were black. The wingspan was pretty long, it looked like almost one metre to me. I also saw a Jabiru Stork once. Huge bird!
I hope to visit there soon!

Dock fouling?

Hi all,
I ran into this blog from an inaturalist user in the Bay Area. I thought it was pretty interesting and something we might want to try if we’re feeling adventurous!

https://chloevanloon.com/2020/10/29/dock-fouling-fun/

Maybe some of you have done this before? They found some great stuff.

We have a new Project!

Beaver Moon Bioblitz Cambridge is here! We're building a community of new and multigenerational nature observers in Cambridge starting with this, the first year of our annual November bioblitz, during the week of the Beaver Moon (Nov. 30). The fun begins Wednesday morning 11/25.

Prizes include nature journaling supplies for the top 10 winners.

Individual observers: We are open to individual observers of all ages.

Teams: Form a team by creating or sharing an iNaturalist account with your team name. Be sure to send us a message to let us know who's on your team. Teams can be a child and an adult family member, a neighborhood group with one iNaturalist account, a class or club, or just a group of friends. This is open to all ages. The rules are just that the observations must be made in Cambridge.

Facebook Live: We'll be going live on Facebook on Wed. 11/25 at 11:30 and again on Friday 11/27 at 10:30 to help you get started if you've never used iNaturalist before. We'll show you how to set up an account and make your first observation. If you plan to use an iPhone, find iNaturalist on the App store or Google Play before you join us on Facebook, if possible.

Spread the word! Gather your team of your friends and family members in Cambridge about this project.

Spring BioBlitz Report

Introduction
One of the more interesting publishing phenomena of the 1980’s and early 1990’s was a book series titled, “A Day in The Life of…” This photojournalism series was organised by Rick Smolan, and each volume featured a selected location, examined over a 24-hour period. Over this time about 50 photographers were commissioned to record their assigned part of the country or state. The result was a series of 13 books, with titles such as Day in the Life of Australia, A Day in the Life of America, etc. The locations featured in the series included, America, the Soviet Union, Japan, California, Spain, Hawaii, Australia, Israel, Africa, China and Thailand. The results were coffee table size books of professional photos, all taken across the selected locale, documenting a single day. Each volume was a unique product, a snapshot of a single day in the lives of ordinary people, across the featured location. Of course, the photos were of professional quality, and selected to illustrate the lives of typical people in the course of a normal day.
It is interesting to look back at these books today, not only for their nostalgic or historic value, but to appreciate the herculean effort it took to organise this simple concept, capture one day in photos. As the years go by such books may be great interest to future generations, illustrating how normal people lived a typical life at a singular point in time.
The concept of a BioBlitz is similar, except the subject is the natural world, at a particular point in time. Our project software has been instrumental in furthering this concept of BioBlitz, providing a platform for such snapshots of nature, at a selected point in time. Looking through iNaturalist, there are 5,442 listings for projects with the word “BioBlitz”. Locations include national parks, schools, backyards and other exotic and less exotic local areas. While not only fun, according to the BioBlitz iNat sites, they also provide valuable information on various populations in nature at a certain point in time. It is useful information, and data which will serve the scientific community for many years.
Like A Day in the Life, organising a BioBlitz is a significant task, relying heavily on motivated individuals to raise awareness of the event and to take a leadership role in its organisation. This is especially true in the early stages of organisation. Think of Australia’s amazingly successful Clean Up Australia Day, which was founded in 1989 and has grown to a massive initiative across the country, and the world. In July, Australasian Fishes published an announcement about the upcoming Spring BioBlitz organised by Thomas Mesaglio (AKA the beachcomber) whose bio-blurb can be found here.
Thomas, always interested in the natural environment, has organised the official participation of Australia in this global event, for the first time. Below is his report of the event, with his thanks for the support of Australasian Fishes project members.
- Harry Rosenthal
Spring BioBlitz Report
In April earlier this year, Australia participated in the City Nature Challenge for the first time, with four cities ─ Greater Sydney, Greater Adelaide, Geelong and Redland City ─ all joining in. Notching up almost 17,000 observations in just 4 days, Australia’s debut was a successful one, especially given the event ran during our autumn when many flowers are no longer in bloom, migratory birds have left, and invertebrates are much harder to find.
The Australian City Nature Challenge organisers decided to build on this success by organising another major BioBlitz, but this time in September during our spring. Rather than limit the event to Australian cities, we decided to get as many Southern Hemisphere cities and regions involved as possible. Pitching the event as the Great Southern BioBlitz (GSB), we launched a broad social media campaign, promoting participation across all the usual channels, as well some handy advertising from Mark (https://www.inaturalist.org/projects/australasian-fishes/journal/38737-spring-bioblitz). Over the course of just a few months, interest in the GSB ballooned, with more and more cities signing up from all around the world until we had an incredible 137 regions or cities across 12 countries and 3 continents.
The event was a huge success. In just 4 days, over 3,000 participants contributed almost 91,000 observations across over 12,000 species! (https://www.inaturalist.org/projects/great-southern-bioblitz-umbrella) Fishes, sharks and rays were strongly represented in the GSB, with 217 species observed over the 4 days, including this awesome eastern cleaner clingfish observed by @harryrosenthal (https://www.inaturalist.org/observations/61281199) and a relatively rare Dunker’s pipehorse found by @tanikacs washed up onto a beach (https://www.inaturalist.org/observations/60696946).
Although Cape Town stormed home to secure another major BioBlitz victory after winning the City Nature Challenge earlier in the year, with Lima also excelling, Sydney put in an awesome effort, finishing in the top 10 for number of observations (2,818) and observers (139), and 4th for number of species seen (1,137). A whopping 41% of Sydney’s diversity was plants, followed by molluscs (16%) and insects (14%). Fishes came in at 10%, highlighting an area to build on for next year!
Although organising BioBlitzes and similar events takes a lot of time, effort and outreach, it’s certainly worth it to see the amazing observations posted, and awesome engagement by naturalists of all ages and from all walks of life. Given the benefits of connecting with nature, including for physical and mental health, BioBlitzes like the GSB are a great way of overcoming those COVID blues. There are also many scientific benefits, with increased efforts to search for organisms uncovering rare and interesting finds, such as this rare, endangered isopod (https://www.inaturalist.org/observations/60688593) found in Victoria by @smellmes.
We’re already starting to plan next year’s GSB, so pencil it into your diaries and expect an even bigger and more successful event!

Brief "Birding by Radar" tutorial

Birding by Radar Birds migrating at night can often be seen on radar on clear nights, especially during nights of heavy migration. Other things known as "ground clutter", such as dust or smoke, can also appear on radar during clear nights. Usually the easiest way to determine whether you're looking at birds or not is to check the wind speed and the speed of the target on the radar; if the target is moving faster than the wind, it's probably not light particles (dust, smoke, etc.) being picked up by the radar, as it would generally be traveling at the same speed as the wind. Visit www.rap.ucar.edu/weather/radar (my favorite site) Choose either velocity mode or reflectivity mode, date/time, and local radar station from the map. VELOCITY mode shows the speed and direction that the target is traveling; warm colors show objects moving away from the radar, cool colors show objects moving towards the radar, and objects moving parallel to the radar will show up as a gray bar intersecting the radar, because they are neither moving directly towards or away from the radar. The direction that the birds are migrating in can be determined by looking at the direction shown by colors as well as the position of the gray band. The birds are traveling at a right angle to this band. The speed can be determined by checking the current wind speed/direction of that area, and comparing that to the speed shown on the radar image. Birds generally travel 10-15 mph faster than the wind. REFLECTIVITY mode shows the density of the target on the radar. Below is an image of migrating birds appearing on the radar at night (velocity mode) Radar image from night of 09/11-09/12/2020, bird migration. Portland Maine

Kun je de iNaturalist App goed gebruiken om buitenshuis organismen op naam te brengen (38)

https://www.tandfonline.com/doi/abs/10.1080/00219266.2020.1739114?

In deze publicatie is een opkomende smartphone app van de website iNaturalist bekeken tijdens de opleiding van eerste jaars studenten biologie om de taxonomie van aquatische ecosystemen(Meren en beken) en Vaste grond ecosystemen (bomen en bladafval ecologie, bodemkunde). De oefeningen betroffen het op naam brengen van organismes met de gewone standard veldgidsen en de standaard wetenschappelijk sleutels en dit werd vergeleken met de bepaling van de taxonomie mbv iNaturalist app adhv de fotos die de studenten in het veld gemaakt hadden.

Ook achteraf werden er onderzoeken gedaan aan de populariteit van deze iNat app., of ze deze app in de toekomst wilden gaan gebruiken en moesten ze aangeven hoe goed deze app een organisme op naam kon brengen. vergeleken met de ouderwetse veldgidsen en wetenschappelijke dichotome sleutels. Het bleek dat de iNaturalist app goed werkte voor organismen die in de vastegrond stonden als de fotos die de studenten gemaakt hadden van goede kwaliteit was. Als je alleen goede of uitstekende fotos gebruikte was 92% tot 97% van de uitkomsten van iNaturalist correct.
Samengevat gaf de iNaturalist app een grotere taxonomisch antwoord met goede wetenschappelijke en Nederlandse, locale namen met daarbij ook waardevolle achtergrondinformatie waardoor de belangstelling van de studenten gewekt werd.

scroll=top&needAccess=true&journalCode=rjbe20 We evaluated an emerging smartphone application, iNaturalist, to increase taxonomic identification and engage first-year undergraduate biology majors in outdoor laboratories of aquatic ecosystems (stream and lake ecology) and terrestrial ecosystems (tree and leaf litter ecology). Labs involved identifying organisms using both standard field guides and keys, and comparing taxonomic identifications using the iNaturalist smartphone application derived from student images of organisms. Students were given post-laboratory surveys which assessed their preference for this increasingly popular smartphone application, whether they were more likely to use the application in the future and rate its ability and ease of use to properly identify organisms compared to traditional keys/field guides. This iNaturalist application worked most consistently for students with terrestrial organisms, when images were of sufficient quality. However, when only medium-high to high-quality photos were used, iNaturalist identifications ranged from 92.3% to 97.3% proper biological taxonomic classifications to standard organismal levels for an introductory biology course. Overall, iNaturalist provided greater taxonomic resolution with proper scientific and common names and additional natural history information for many organisms, piquing student interest. Incorporating this smartphone technology may increase identification of local biodiversity and student engagement in the biological sciences.

Transplantatie Krabbescheer door Noorderzijlvest bij DeHeld Gravenburg(37)

Nalv Protest van IVN Groningen
GESCHREVEN DOOR
Jan Been Jan Been
Verslaggever

Waterschap Noorderzijlvest is dinsdag aan de Natalie Barneykade in Stad begonnen met het terugbrengen van krabbenscheer. De waterplant is belangrijk voor de zeldzame libel de groene glazenmaker, die een jaar geleden plotseling verdween uit de sloot. Deze Groene Glazenmaker deed nog mee aan de verkiezing Soort van de Provincie Groningen.

Natuureducatie-organisatie IVN Groningen-Haren diende een klacht in, die leidde tot de hersteloperatie van dinsdag.

In de sloot gestort
De transplantatie gebeurt met een maaiboot die grote plakken krabbenscheer uit een sloot tussen de Jakob Israël de Haanstraat en de Jacob Schorerstraat uit het water vist en naar een aanhanger brengt. De waterplant wordt vervolgens enkele honderden meters verderop in de sloot bij de Natalie Barneykade gestort. Het waterschap gaat ervan uit dat-ie vanaf volgend voorjaar weer aangroeit.

Harold van Oosten van Noorderzijlvest: 'We hebben onderzocht waarom de plant een jaar geleden zomaar verdwenen was. We hebben geen verklaring kunnen vinden. Het is gebeurd tijdens opschoningswerkzaamheden. Wij hebben daar geen opdracht voor gegeven. Wie dat wel heeft gedaan, hebben we niet meer kunnen achterhalen.'

Krabbenscheer mag niet zomaar verwijderd worden
Toch voelt Noorderzijlvest zich verantwoordelijk voor het herstel. Het is haar eigen sloot en het schap werkt met de landelijke Gedragscode Flora en Fauna waarin staat dat de krabbenscheer niet zomaar mag worden verwijderd.

'Als je het weghaalt dan moet je de helft laten staan. Gelukkig komt de krabbenscheer hier in De Held veel voor. We halen de helft weg uit deze sloot en transplanteren dat naar de plek waar het verdwenen is.'

De krabbenscheer (linksonder) is teruggestort in de sloot aan de Natalie Barneykade (Foto: Jan Been/RTV Noord)
Berber de Jong, ecoloog bij Noorderzijlvest: 'De krabbenscheer is een inheemse plant. Hoe het kan dat hij in de sloten in De Held zo goed gedijt weten we niet. Het is geen beschermde plant, maar omdat hij van groot belang is voor de groene glazenmaker zijn we er heel voorzichtig mee.'

Het belang van krabbenscheer
De groene glazenmaker is afhankelijk van de krabbenscheer. De libelle legt zijn eitjes aan de onderkant van het blad van de waterplant en doet dat alleen bij deze soort. De Jong: 'Noorderzijlvest vindt biodiversiteit belangrijk en daarom is het van belang om de krabbenscheer omwille van de glazenmaker zoveel mogelijk te beschermen. Vandaar dat we deze 'transplantatie' zijn begonnen.'

Transplantatie Krabbescheer door Noorderzijlvest bij DeHeld Gravenburg(37)

Nalv Protest van IVN Groningen
GESCHREVEN DOOR
Jan Been Jan Been
Verslaggever

Waterschap Noorderzijlvest is dinsdag aan de Natalie Barneykade in Stad begonnen met het terugbrengen van krabbenscheer. De waterplant is belangrijk voor de zeldzame libel de groene glazenmaker, die een jaar geleden plotseling verdween uit de sloot. Deze Groene Glazenmaker deed nog mee aan de verkiezing Soort van de Provincie Groningen.

Natuureducatie-organisatie IVN Groningen-Haren diende een klacht in, die leidde tot de hersteloperatie van dinsdag.

In de sloot gestort
De transplantatie gebeurt met een maaiboot die grote plakken krabbenscheer uit een sloot tussen de Jakob Israël de Haanstraat en de Jacob Schorerstraat uit het water vist en naar een aanhanger brengt. De waterplant wordt vervolgens enkele honderden meters verderop in de sloot bij de Natalie Barneykade gestort. Het waterschap gaat ervan uit dat-ie vanaf volgend voorjaar weer aangroeit.

Harold van Oosten van Noorderzijlvest: 'We hebben onderzocht waarom de plant een jaar geleden zomaar verdwenen was. We hebben geen verklaring kunnen vinden. Het is gebeurd tijdens opschoningswerkzaamheden. Wij hebben daar geen opdracht voor gegeven. Wie dat wel heeft gedaan, hebben we niet meer kunnen achterhalen.'

Krabbenscheer mag niet zomaar verwijderd worden
Toch voelt Noorderzijlvest zich verantwoordelijk voor het herstel. Het is haar eigen sloot en het schap werkt met de landelijke Gedragscode Flora en Fauna waarin staat dat de krabbenscheer niet zomaar mag worden verwijderd.

'Als je het weghaalt dan moet je de helft laten staan. Gelukkig komt de krabbenscheer hier in De Held veel voor. We halen de helft weg uit deze sloot en transplanteren dat naar de plek waar het verdwenen is.'

Berber de Jong, ecoloog bij Noorderzijlvest: 'De krabbenscheer is een inheemse plant. Hoe het kan dat hij in de sloten in De Held zo goed gedijt weten we niet. Het is geen beschermde plant, maar omdat hij van groot belang is voor de groene glazenmaker zijn we er heel voorzichtig mee.'

Het belang van krabbenscheer
De groene glazenmaker is afhankelijk van de krabbenscheer. De libelle legt zijn eitjes aan de onderkant van het blad van de waterplant en doet dat alleen bij deze soort. De Jong: 'Noorderzijlvest vindt biodiversiteit belangrijk en daarom is het van belang om de krabbenscheer omwille van de glazenmaker zoveel mogelijk te beschermen. Vandaar dat we deze 'transplantatie' zijn begonnen.'

A Breathtaking 20,000 Nature Observations Made In NVCT's First Inaugural Nearby Nature BioBlitz

Northern Virginia Conservation Trust (NVCT) just completed our First Inaugural Nearby Nature BioBlitz! The exciting and enlightening month-long campaign turned everyday citizens into scientists as they explored and photo-documented nature within their own Northern Virginia and DC metro area communities. 

Campaign participants uploaded their fantastic photos to iNaturalist.org, sharing their breathtaking observations of river otters, margined calligraphers, crowded parchment, and more. 

NVCT is proud of our community's participation as each observation provides a deeper understanding and closer connection between us and the natural world. With over 20,000 observations, over 2,600 species, and nearly 100 observers, NVCT's Nearby Nature BioBlitz is a huge success!

Izabella Farr finished first, having the most observations (3,444) and most species observed (898). Capital Naturalist came in a close second with 2,685 observations that comprised 845 species. In third came WildphotosDMV with 2,685 observations including 692 species.

The grand prize for Most Research Grade Observations went to Izabella Farr with 1,620 observations with 537 species over the course of the month. Stephen John Davies was the grand prize winner for Most Threatened Species Observations with 51 observations and 13 species observed. And the winner of our Observer Raffle is Penny Firth with 139 observations with 104 species observed.

Thank you to all of our citizen scientists for helping to make NVCT’s First Inaugural Nearby Nature BioBlitz a huge success! 

We hope you've enjoyed learning about the incredibly diverse wildlife we are fortunate to have in Northern Virginia. NVCT works to protect the delicate ecosystems that make our communities so special. To help, please donate today.

The Northern Virginia Conservation Trust (NVCT) is a regional nonprofit land trust that forever conserves, manages, and advocates for land with natural, historical, and cultural value to our Northern Virginia communities. NVCT works with conservation partners, local governments, and private landowners to preserve, restore, and steward land in Northern Virginia. NVCT's service area includes 2.9 million residents in a fast-growing region that needs more outdoor recreation spaces. Since its founding in 1994, NVCT has protected more than 8,000 acres in urban and rural areas.

Project Description

Hello everyone,

I am an Associate of the Centre of Agriculture Biosciences International (CABI)

CABI has over a 100-year history in Integrated Pest Management and scientific publication and information management in the areas of agriculture and the environment. Since 2003, CABI’s Caribbean and Central American Centre (based in Trinidad) has lead the challenge of managing invasive species in the Caribbean.

We would like to seek volunteers to assist us to define how serious the mongoose problem is in Trinidad, especially to track the population post-closure of the sugar cane industry that may have inadvertently control the population. By joining the project we can get an idea of their distribution.

We are also seeking to get funding to do a formal assessment of the population and their impacts. CABI's work in another project in St. Kitts and Nevis (i.e., nest predation studies) has shown that mongoose is a major prey of bird eggs.

Thank you in advance for your cooperation.

Cheer

75 000 !!!

Дорогие друзья!

Проект "Флора Москвы" занимает уверенное второе место среди регионов-участников портала "Флора России" как по числу наблюдений, так и по числу наблюдателей! На днях мы преодолели важный рубеж: 75 000 наблюдений. Москва остаётся лидером "Флоры России" по плотности наблюдений и по числу подписчиков регионального проекта (132 человека).

Наша статистика: 75 613 наблюдений - 1 132 вида - 1 181 эксперт - 1 801 наблюдатель

Небольшие напоминалки:
● На майские праздники состоится традиционный четырехдневный марафон City Nature Challenge. Москва в игре! Уже работает российское табло. Ищите там Москву и подписывайтесь, чтобы не пропустить новости челленджа. В прошлом году из-за карантина участие Москвы было скомканным.
● Одуванчик сфотографировали в Москве 1177 раз. Просто чудовищная цифра. Ответ на вопрос "Зачем снимать много раз одно и то же?" дан здесь. Это очень важно для нашего проекта! Однако если вы хотите, чтобы ваши наблюдения были определены, придётся поучиться у классиков.
● Очередное объявление о взаимодействии iNaturalist и GBIF помогло ещё нескольким участникам сделать выбор в пользу открытых лицензий. О том, что это такое и зачем стоит лицензировать свои наблюдения, рассказно здесь. Кстати: каждый из топ-100 наблюдателей проекта "Флора России" уже перешёл на открытые лицензии.
● Приглашаем всех участников iNaturalist подписаться на проект МГУ "Флора России" и региональные страницы этого портала. Например, на "Флору Москвы". В паспорте каждого наблюдения будет, таким образом, отражена как ссылка на общероссийский проект, так и региональная принадлежность наблюдения.

В общей сложности для добавления очередных 25 000 наблюдений нашему сообществу потребовалось около 4 месяцев (https://www.inaturalist.org/projects/flora-of-russia/journal/38553-600-000). Давайте отметим тех наблюдателей, кто загрузил с 20 июля 2020 г. больше одиннадцати видов:

Sea turtle true in INat.

Hola espero que se encuentren muy bien. (English below)

Desde que llegué a INaturalist he estado agradecido por esta red, que me ha permitido aprender y actualizarme en algunos taxones de mi interés y aportar mis conocimientos en los taxones de los que soy experto.
Quería comentarles, que una de las principales razones por la que estoy aquí en INat es que los registros de tortugas marinas puedan ser utilizados para apoyar su conservación y otras áreas del conocimiento de estas especies.
Sin embargo, he conseguido muchos errores en estos récords, empezando por lo más básico como la identificación, y una lista larga adicional.
Por esto he decidido ir haciendo y corrigiendo las ID solo en base a las evidencias visibles que definen las especies y evitar identificar por apreciación libre.
Es claro que todos podemos cometer un error, es bueno estar dispuestos a escuchar, hacer preguntas y dar respuestas para aclarar dudas. Yo lo estoy.
Por todo esto me atrevo a pedir su ayuda y paciencia.

Saludos y gracias.

Hello I hope you are very well.

Since I came to INaturalist I have been grateful for this network, which has allowed me to learn and update myself on some taxa of my interest and contribute my knowledge in the taxa of which I am an expert.
I wanted to tell you that one of the main reasons why I am here at INat is that sea turtle records can be used to support their conservation and other areas of knowledge of these species.
However, I have gotten a lot of errors in these records, starting with the most basic like identification, and an additional long list.
For this reason I have decided to go on making and correcting the IDs only based on the visible evidences that define the species and avoid identifying by free appreciation.
It is clear that we can all make a mistake, it is good to be willing to listen, ask questions and give answers to clarify doubts. I am.
For all this I dare to ask for your help and patience.

Greetings and thanks.

5000 наблюдений !!!

Дорогие друзья!

Проект "Флора Республики Алтай" взял сегодня первую серьёзную отметку - 5000 наблюдений. Горный Алтай пока среди крепких середняков портала "Флора России" по числу сделанных наблюдений, но прогресс очевиден!

К сожалению, по очень богатой алтайской флоре у нас остро не хватает знающих экспертов, готовых трудиться над разбором бэклога: треть наблюдений пока не верифицированы или вовсе не определены. Это один из наихудших показателей в России (https://www.inaturalist.org/projects/flora-of-russia/journal/44051-regionalnyy-srez-bekloga).

Другой проблемой является то, что среди активных наблюдателей нет ни одного местного жителя (поправьте, если я не прав), из-за чего у нас нет полно выявленных горноалтайских локальных флор. При этом облако точек стройными цепочками протянулось вдоль основных трасс региона.

Наша статистика: 5 006 наблюдений - 894 вида - 256 экспертов - 179 наблюдателей

Давайте отметим тех наблюдателей, кто загрузил в проект по флоре Горного Алтая больше трёх видов:

Quick update & stickers!

Hi everyone,
Thanks to everyone who continues to add their weekend observations!
Even bigger thanks to those who are helping to identify everything as it comes in...
If you are in doubt about a species ID, it is best to classify at a higher level (one you are fairly sure about - even if that is something very general like plants or flies etc), so that someone with more expertise can then assist with narrowing it down. This will help us get an accurate species list.
By this coming weekend we hope to start compiling initial reports, so it would be fantastic if you could aim to get the bulk of your remaining observations uploaded before the end of the week!
Thanks again everyone!
Team Bioblitz T&T

Hybrid Hunt Update + Cape Perpetua Collaborative Talk

Hey Ammophila-philes!

Last week I gave a talk for the Cape Perpetua Collaborative. I had a great time virtually interacting with the Cape Perpetua community; thanks to Tara for inviting me! I used this opportunity to describe the discovery of the hybrid beachgrass and the goals of this iNaturalist project. It's pretty similar to other talks I've posted here except that at the end I gave an update on successes of the "hybrid hunt!" Check it out on YouTube (or read below for spoilers).

https://www.youtube.com/watch?v=KuWdkquOGbY

CAUTION: TALK SPOILERS!

Over the summer we identified 6 new patches of the hybrid at 4 sites! One of these sites was discovered by a community member! 2 hybrid patches were found in Bob Straub State Park (just south of Pacific City) and the rest were found on the Long Beach Peninsula. Huge thanks to everyone who has been scouring the beaches for this fascinating plant. There is certainly more out there to find so keep your eyes on those ligules!

With gratitude,

Rebecca

What Can iNaturalist Tell Us About Monarchs in Canada?


By Sara Cecile

Most people can identify the tell-tale orange and black patterns of a Monarch Butterfly, a staple species in Canada.


But did you know that this beautiful butterfly is also at risk? The Monarch is assessed as Endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).



A Monarch Butterfly observation from iNaturalist user Paul Tavares.

The Monarch Butterfly is a unique species which migrates annually from breeding grounds in southern Canada to its overwintering habitats in the south. There are two Canadian populations of Monarch: the western population, which breeds in B.C. and migrates to California, and the eastern population, which is distributed from Alberta to the Maritimes and overwinters in Mexico.

This impressive insect faces many threats and is in need of conservation action. In an attempt to discover more about the Monarch Butterfly in Canada, I reviewed the current data available on iNaturalist (a citizen science project that documents wildlife) to see if I could find any patterns or interesting information about this species at risk. Here’s what I found.

There have been over 13,000 observations of Monarchs in Canada on iNaturalist!



Map of Canada showing all iNaturalist research grade observations of Monarchs in Canada 2008-2020

This is an amazing number of observations. Due to an exponential increase in iNaturalist observers over time, the number of observations of Monarchs in Canada have greatly increased over the years. As a potential result of this increase, the active season of the Monarch in Canada has been observed getting longer each year, with sightings as early as April and sometimes lasting into November.

Some of the locations of observations were surprising, as Monarchs were sighted in areas outside of their normal Canadian range. One of the sightings was in Gros Morne National Park, Newfoundland. Yes, Monarchs crossed the Atlantic to reach the island of Newfoundland! Another Monarch was observed in northern Ontario near James Bay! The northernmost observation was near Edmonton, Alberta.

The number of Monarch observations in Canada weren’t as high in 2020 as they were in 2019.

Comparing the number of observations from January to mid-September for 2019 and 2020, there are about 1,000 fewer observations in 2020. This defies the general trend of increasing observations annually, begging the question if 2020 was not a great year for the Monarch.

How To Help


There are many ways you can help the Monarch and help monitor this species. You can start by further educating yourself, as there are many resources available to you online including Hinterland Who’s Who, Monarch Watch, Monarch Joint Venture, Journey North, and Mission Monarch.

Monarchs depend on milkweed plants to lay their eggs on and feed them in their caterpillar stage, so planting local species of milkweed is an action you can take to help the Monarch. You can also plant other native wildflowers that produce nectar for the adult Monarchs to feed on.

Check out our blog on how to create your own mini Monarch meadow! Want to contribute to science? You can by documenting your observations of Monarchs using iNaturalist.

Qu’est-ce qu’iNaturalist peut nous dire au sujet du papillon monarque au Canada?

Par Sara Cecile

La plupart des gens peuvent identifier les motifs noirs et orange du papillon monarque, une espèce emblématique du Canada.

Mais saviez-vous que ce magnifique papillon est aussi une espèce en péril? Le monarque est désigné comme étant une espèce en voie de disparition par le Comité sur la situation des espèces en péril au Canada (COSEPAC).


Un papillon monarque
Un papillon monarque enregistré par l’utilisateur d’iNaturalist Paul Tavares.

Le papillon monarque est une espèce unique qui migre annuellement de ses aires de reproduction dans le sud du Canada vers ses habitats d’hivernage dans le sud. Il y a deux populations canadiennes de monarques : la population de l’ouest, qui se reproduit en C.-B. et migre vers la Californie, et la population de l’est, répartie de l’Alberta jusqu’aux Maritimes, qui se rend au Mexique l’hiver.

Cet impressionnant insecte est confronté à de nombreux défis. Nous devons agir maintenant pour le conserver. Afin d’en apprendre plus sur le papillon monarque au Canada, j’ai examiné les données disponibles dans iNaturalist (un projet de science citoyenne qui consigne les animaux sauvages) pour voir s’il existait des tendances ou des renseignements importants sur cette espèce en péril. Voici ce que j’ai trouvé.

Il y a plus de 13 000 observations de monarques au Canada dans iNaturalist!

C’est beaucoup d’observations! En raison de l’augmentation exponentielle d’observateurs dans iNaturalist au fil des ans, le nombre d’observations de papillons monarques s’est accru. Comme résultat potentiel de cette augmentation d’observations, la saison active des monarques au Canada semble être plus longue tous les ans, des observations ayant été enregistrées aussi tôt qu’avril et aussi tard que novembre.

Certains des endroits où l’on a observé des monarques étaient étonnants, car ils étaient à l’extérieur de leur aire de répartition habituelle. Une des observations était dans le parc national du Canada Gros Morne à Terre-Neuve-et-Labrador. Oui, le monarque avait traversé l’Atlantique pour se rendre sur l’île de Terre-Neuve! Un autre monarque a été observé dans le nord de l’Ontario près de la baie James! L’observation la plus au nord été à Edmonton en Alberta.

Le nombre d’observations de papillons monarques au Canada était moins élevé en 2020 qu’en 2019.

Nombre d’observations de papillons monarques de calibre « recherche » au Canada dans iNaturalist de 2008 à 2020. Il est à noter que les observations affichées pour 2020 s’arrêtent à la fin de juillet.

En comparant le nombre d’observations de janvier à la mi-septembre de 2019 et de 2020, on remarque qu’il y a environ 1 000 observations de moins en 2020, ce qui va à l’encontre de la tendance générale de l’augmentation du nombre d’observations annuellement et nous mène à penser que 2020 n’a pas été une très bonne année pour le monarque.

Façons d’aider

Il y a plusieurs façons d’aider le monarque et de surveiller l’espèce. Vous pouvez commencer en vous renseignant davantage. De nombreuses ressources sont accessibles en ligne, dont Faune et flore du pays, Monarch Watch, Monarch Joint Venture, Journey North et Mission Monarch.

Le monarque dépend de l’asclépiade pour pondre ses œufs et le nourrir au stade de chenille. Vous pouvez donc en planter pour aider ce papillon. Vous pouvez aussi cultiver d’autres fleurs sauvages qui produisent du nectar comme source de nourriture pour le papillon adulte.

Consultez notre blogue sur la façon de créer votre propre petit pré pour le papillon monarque! Voulez-vous contribuer à la science? Vous pouvez consigner vos observations de monarques dans iNaturalist.
