Abstract

Forest Park faces numerous major ecological stresses, demonstrated in part by the significant lack of late-successional tree recruitment and invasion by ivy (Hedera spp.) and other invasive plant species. While ivy removal and revegetation has been a focus of restoration efforts, limited resources and unanswered questions about the impact of ivy and ivy removal on this ecosystem present an opportunity for re-evaluating restoration goals and techniques. Leveraging past and current ecological research on Forest Park and similar urban ecosystems, we evaluate Forest Park’s current ecological health compared to the restoration goals of managing to an old-growth reference site, the role of ivy, present an Integrated Pest Management (IPM) framework for deciding when and how to treat ivy within the Park, and discuss possibilities for post-treatment revegetation as a tool for building resistance to ivy reinvasion and re-establishing a self-regenerating forest ecosystem.

Recommendations for ivy management in Forest Park

Forest Park faces numerous major ecological stresses, demonstrated in part by the significant lack of late-successional tree recruitment and invasion by ivy (Hedera spp.) and other invasive plant species.

Leveraging past and current ecological research on Forest Park and similar urban ecosystems, we evaluate Forest Park’s current ecological health compared to the restoration goals of managing to an old-growth reference site, the role of ivy, present an Integrated Pest Management (IPM) framework for deciding when and how to treat ivy within the Park, and discuss possibilities for post-treatment revegetation as a tool for building resistance to ivy reinvasion and re-establishing a self-regenerating forest ecosystem.
