Fencing: The plots in experiment 003 were 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 extended 60cm above the ground, and poultry netting extended to 1.8m above the ground.

Fertilization: Fertilizer was mixed and spread by hand twice a year, once in early May and once in late June. Each plot got the fertilizer mixture specified by its fertilizer treatment code. For a list of fertilizer treatments for each plot, see file trmte03.

Mammal Trapping: Small mammals were 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 were trapped out of the fields as soon as they appeared. Gopher mounds weare then removed and buried vegetation was unburied.

Watering: Treatment "H" plots got 24 gallons of water per week between May 1 and mid-September. This was at a rate of 4 gallons of water per meter squared per week. There were four of these plots in each of the four fields.

Burning: Field D is within burn compartment #6 (106). This field was burned 2 years out of every three. On May 5, 1995 a wild fire burned all of the plots in experiment 3 in field B
