Abstract
In Part 1, we assessed browse trend across a wide geographic area of Mt. Haggin Wildlife Management Area by conducting surveys of browsing-related architectures. Those data were qualitative. Below we describe the periodic collection of quantitative data from permanently marked locations; we refer to this phase of the trend assessment program as "monitoring." Trend was monitored by three methods: 1 Repeat photography. 2 Comparison of the height of live stems with the height of stems killed by browsing (LD Index). 3 Net annual stem growth rate (NAGRL3). The photography provides an assessment of trend from the comparison of photographs taken at intervals of a few years. The LD Index and NAGRL3 measurements provide an immediate assessment of trend.
