Spiders are very effective biocontrol agents, particularly when their communities are more diverse. In the progression of more sustainable and natural agriculture, supporting spider communities in California vineyards has potential to keep vines safer from pests. I decided to observe spider taxonomic and guild richness, as well as abundance, on crop and non-crop vegetation in vineyards, while recording a sites plant species richness and assigning each of those species to be native or not. I set out to determine what factors support more spider diversity, and ultimately, how those factors may encourage spider communities on the vines themselves.
