Portal Site and Methods

Methods:

Methods.md contains a complete description of the methods for data collected at the site.

Site Description:

Figure 1 is a visualization of the entire site. The entire study area is approximately 20 ha and within this area there are 24 experimental plots. Each plot is 0.25 ha (50m x 50m) and fenced with hardware cloth topped with aluminum flashing. Access to these plots by rodents is regulated by gates cut into fencing.

In Portal_UTMCoords we have provided GPS coordinates for the rodent stakes, plant quadrats, plot corners, and the weather station.

Treatments:

As a result of direct changes to the plots, or the termination of experimental manipulations, changes in treatment assignment occurred in 1985, 1987, 2005, 2009 and 2015. These changes are described in Portal_plot_treatments.

Portal_plots can be used to correctly assign each plot's treatment over time.

Please refer to Methods.md for a complete description of how these data were collected.
