Three years of past burning responses of three perennial grasses were evaluated by comparing a burned area with an adjacent control (unburned) area. The average leaf length of Cusick bluegrass and Thurber needlegrass was shortened by burning in all 3 years, but leaf shortening was inconsistent for bluebunch wheatgrass. Burning increased the number of flowering culms per clump for Cusick bluegrass during the second year of postburning and for Thurber needlegrass during the third year. The average number of flowering culms per clump in bluebunch wheatgrass was greater in the burned area for all 3 years of postburning. Culm and spike lengths of bluebunch wheatgrass were increased by burning for the first 2 years. Cusick bluegrass and Thurber needlegrass generally responded to burning with shortened culms and spikes. The basal area of Cusick bluegrass and Thurber needlegrass was reduced by burning. Phytomass production of bluebunch wheatgrass showed an increase during the 3 years of postburning, whereas Cusick bluegrass and Thurber needlegrass showed a reduction in phytomass production. No single measurement provided a way to evaluate overall plant responses.
