Fencing: The plots in experiment E025 are enclosed by a fence to exclude mammalian herbivores. Galvanized welded-wire hardware cloth with 6mm x 6mm openings was buried to a depth of 84cm. Additional hardware cloth extends 60cm above the ground, and poultry netting extends to 1.8m above the ground.

Fertilization: Plots are fertilized at one of the following sets of times:

1. 1st & 3rd weeks of May
2. 1st & 3rd weeks of June
3. 1st & 3rd weeks of July

Each plot gets the fertilizer mixture specified by its fertilizer treatment code.

Mammal Trapping: Small mammals are trapped as often as possible to keep the resident population low. A list of the number and kind of mammals taken from each field is in the small mammal documentation file. Pocket gophers are trapped out of the fields as soon as they appear. Gopher mounds are then removed and vegetation is unburied. On May 5, 1995, a wildfire burned all of the plots in experiment 25 in field B.
