As part of this project, we are also interested in how competition from resident vegetation and generalist rodent consumers influence plant community assembly. We are conducting a large scale seed addition experiment where we have addeed locally uncommon species to disturbed or undisturbed plots in and out of larger rodent exclosures across 10 sites in the Blackfoot Valley. This work is quantifying the strength of dispersal limitation and local filters such as competition and seed predation in influencing the assembly and ultimate composition of local communities.
