This research addresses the question of how to maintain (presumably uniform) rangeland forage production across both wet and dry years. Seasonal distribution of wet-year rainfall is outside the purview of the experiment, but should be recognized as a possible variable.  
Here, plots simulating wet years have grasses only. (Wild oats? Medusahead? Soft chess? All of the above?)  
Plots simulating dry years have forbs (erodium) only.  
A third treatment has a mixture of both (ratio not given).  
The plot views presented do not clearly show the appearances of the three treatments. A cursory glance tells one its mostly all grass. (Such aberrations "come with the territory", Lauren; you just have to go with the flow.)  
Water provided manually in dry weather conditions does not simulate the environmental conditions of a wet year.  
It is not stated whether this area, including plots, is left to grow "as is" from year to year.  
Problematical is whether satisfactory extrapolation is possible from these experimental conditions to the more conventional situation of grazed pastures that are managed much differently, and where oft-repeated defoliations throughout the growing season is the norm. But that gives you opportunity to declare "More research is needed!"  
It was delightful to listen to the background music provided by (?)a mountain jay(?). Didn't sound like a mocking bird, and it couldn't have been a meadow lark.
