Rodgers J, Bromberg J, Baxter T. 2007. Cape-Ivy Removal Golden Gate National Recreation Area and Point Reyes National Seashore PMIS 80291 NRPP Resources Management FY2004-FY2006 Final Report. Point Reyes Station, California
This report describes efforts made by the National Park Service to eradicate the invasive Cape-Ivy plant from areas of high priority occurrences. PMIS Project 80291 funded Cape-ivy treatments in FY2004 through FY2006 with a goalof complete eradication of all previously known patches of Cape-ivy (Delairea odorata)at Point Reyes National Seashore (PORE) and local eradication of high-priorityoccurrences with containment of larger infestations at Golden Gate National RecreationArea (GOGA). Cape-ivy is one of the highest priority non-native invasive plants for bothPORE and GOGA. It spreads rapidly and directly impacts numerous threatened andendangered species through habitat conversion and alteration of soil and water chemistry.Cape-ivy out-competes all other plants species by completely covering ground surfacesand climbing tree and shrub limbs to shade out native plants and pull down trees. Somestudies have also shown that Cape-ivy contains toxic alkaloids which may have effects onfish, mammals and invertebrates. The total removal completed during the three year project was 27.72 acres at PORE and 29.9 acres at GOGA. This report provides further detail on mapping and surveying, site selection, methods, results and monitoring for the purpose of guiding future follow-up and monitoring.
