Experiment 005 - Effect of Herbivores on Vegetation Treated with Different N Levels and the Effect of N Addition on Herbivore Populations.

The purpose of this experiment is to study the effect of NH4NO3 addition on vegetation and herbivore populations and the effects of various herbivores on vegetation treated with different nitrogen levels. This experiment is being conducted in fields A, B, and C and is nested within the macroplots of E004. There are 4 fence exclosures each designed to exclude a specific group of herbivores, a fence exclosure to exclude all 4 groups, a fence that should exclude no herbivores to measure fence effects, and a plot with no fence as a control. Exclosures are 2 by 4 meters and are located in macroplot subsections 3 and 8. Herbivore treatments are randomly placed in the grid. For a description of fertilizer added to E005, see file fertilization details. For a list of treatments, see the treatment layouts in file trmte05.
