Cedar Creek is in the process of implementing an enemy removal experiment to survey the impact of various natural enemies on plant community composition, diversity, productivity. There are six treatments, targeting soil oomycete pathogens, above-ground fungal pathogens, insect herbivores, mammals, all enemies combined, and a control. This experiment is to be implemented at two sites. The first site has 5 treatments (the entire site is enclosed by a deer fence and gophers are trapped, so the mammal exclusion treatment is already included) and 41 replicates for a total of 205 plots. The second site has 6 treatments (individual deer fences are constructed and gophers are trapped for the mammal exclusion treatment) and 8 replicates for a total of 48 plots. Results are forthcoming.
Fences in E001 and E002 from 1992 on. In 2004, the fences excluding mammalian herbivores were removed; except in half of the plots in one field in E001.
