Native revegetation following Eucalyptus removal and burning on Santa Cruz Island, California
This study focused on revegetation following Eucalyptus removal as part of the Santa Cruz Island Prisoners Harbor Restoration project. There is concern that oils from Eucalyptus leaf litter, combined with the effect of burning log piles as part of removal process, will affect native seed germination and establishment. We surveyed sites in the Bosque de Cabrillo, La Selva, and Rincon Papal eucalyptus groves to monitor vegetation development over time. To complete this study, we established paired plots in burned patches and adjacent unburned areas in three treatment types: burned and seeded, burned and unseeded, and mulched and seeded. We placed non-permanent markers (flags) at the center point of each sample location, and established three 10 meter transects radiating from the center of these points. Each transect was sampled with point intercept methods to measure plant species diversity and percent cover. We also collected topsoil samples to complete germination trials off-site which allowed us to have good results to present above and beyond the vegetation changes in the first monitoring year. The study will began in Fall 2015 and concluded in Spring 2016.
