My project is focused on understanding how site conditions effect the ability of invasive species to colonize new habitat. A species’ “invasiveness” is directly related to their ability to out compete native species. In the Capital Regional District of B.C. , Hedera helix is arguably one of the most detrimental and pervasive alien species. Unlike many other local invasives, H. helix easily penetrates undisturbed or relatively undisturbed habitats, such as the second growth forest of Cuthbert-Holmes Park where I carried out my data collection. In many areas of the C.R.D., native plant diversity is severely reduced as a direct result of H. helix invasion. By deepening our understanding of which sites are most vulnerable to H. helix invasion (in my case, focusing in on a single abiotic factor), we can allocate resources for invasive species control.
