"Effects of English Ivy (Hedera Helix) on Seed Bank Formation and Germination"

This journal article from the American Midland Naturalist 157(2):250-257 (2007) discusses the effects of English ivy on the forest ecosystem, specifically on the seed bank formation and germination. Because English ivy is an invasive species, it is necessary to understand the mechanisms that allow this plant to affect the native landscape. Ivy's invasive nature is facilitated by its rapid vegetative growth rate and efficient seed germination. Therefore, in this study Biggerstaff and Beck sampled the seed bank and the summer and fall seed rains. They sampled areas with and without ivy. They found no significant difference between these two sites. They also looked at the allelopathic effects of ivy on Correopsis lancelota seeds and found a marginally significant germination rate reduction of C. lancelota seeds only when ivy plants were present. This suggests that native plants would be successful in previously ivy covered places if this ivy was removed.
