Abstract
Patrick’s Point State Park has experienced a tremendous growth of English Ivy that has causing a damage to park resources. The goal of this study was to accurately map English Ivy habitats, estimate coverage, and survey English Ivy colonization effects on tree trunks. The results showed that the English Ivy growth has decreased from 8.0 acres to 6.5 acres between 2015 and 2016 respectively due to park restoration activity supported by volunteer organizations. The English Ivy growth on tree trunks was significant for Western Hemlock and Sitka Spruce. With this project the park will be able to locate the most English Ivy spots that require attention, and monitor their growth rate.
