Title: Experimental trampling of vegetation. I. Relationship between trampling intensity and vegetation response

Author: Cole, David N.

Date: 1995

Source: Journal of applied ecology. 32(1 ): 203-214

Publication Series: Not categorized

Description: 1. Experimental trampling was conducted in 18 vegetation types in five separate mountain regions in the United States. Each type was trampled 0-500 times. Response to trampling was assessed by determining vegetation cover 2 weeks after trampling and 1 year after trampling.

2. Response varied significantly with trampling intensity and vegetation type. Trampling intensity and vegetation type explained more of the variation in vegetation cover 2 weeks after trampling than they did 1 year after trampling.

3. For most vegetation types, the relationship between vegetation cover after trampling and trampling intensity was best approximated by a second order polynomial of the form Y = A - BX + CX2. The relationship was linear in a few vegetation types.

4. The curvilinearity of the relationship between trampling intensity and surviving vegetation cover decreased with increases in resistance, tolerance and species diversity of the vegetation type.
