Proximity and Prevalence of Invasive Plant Species in Correlation to Points of Entry on Santa Rosa Island

Abstract

I surveyed invasive plant species in points of entry, or areas where people first enter the island, because these areas have high potential for disturbance. Invasive plant species can be damaging to native wildlife, vegetation, and habitats, therefore it is important to study the spread and distribution patterns of invasive plant species in order to create a management plan if necessary. I cataloged all species within two points of entry; the area directly connected to the pier and the campground. Using GPS coordinates as well as taking informative data on their populations, I was able to analyze how much of an impact invasive plants were making on these areas. I analyzed all this data to assess the level of disturbance and report it to the National Park Service in order to aid them in a monitoring program. I also performed a separate study in which I created random plot points at different distances from the pier point of entry in order to assess whether or not invasive plant prevalence decreases further from the point of entry. I hypothesized that (1) invasive plant species will be more prevalent in the campground than by the pier; (2) prevalence of invasive plants will decrease further from the first point of entry
