Comparison of Seedling Planting Density on Growth of Douglas-fir Seedlings

Purpose

Project is designed to compare two spacing regimens for planting of Douglas-fir seedlings. Clusters of Douglas-fir trees were planted at 25' spacing and compared to a conventional 8'x8' spacing. Interplanting with alder to test soil enrichment effects.

Oak Creek Snails

Purpose

Trays filled with stream sediment will be placed in the channel for colonization by stream invertebrates. Snail densities in each tray will be manipulated to test the effect of snails on the abundance of other stream invertebrates. One half of the chann

Northern Pygmy Owl Density in McDonald Forest

Purpose

This project is designed to correlate owl abundance to a stand type and to get a baseline on owl numbers. Twenty monitoring stations will be set up along the main road. Eight minutes at each site for 2 days a week .5 hours before sunrise until 10:00 a.m
