Cliff Lake Bench Research Natural Area: Problems Encountered in Monitoring Vegetation Change on Mountain Grasslands.

摘要

Vegetation data collected on mountain grasslands in southwestern Montana in 1969 and again in 1988 serve as an example of problems likely to be encountered in attempting to monitor the effects of climatic change on vegetation. Species production, frequency, and vegetation composition differed significantly, but these were believed to be a result of short-term peculiarities of the sample years, rather than evidence of long-term vegetation change. Ways are suggested to reduce the effects of some of the problems encountered.
