    The first forests (>12 BP) were an open mixture of conifers and deciduous trees, chiefly Tsuga mertensiana, Abies, Pinus contorta, and Populus on a landscape subject to erosion. Just before 12 BP, the pioneer species Picea sitchensis, Alnus rubra, and A. sinuata became important constituents of the by: The Ashland Forest Reserve, which set as acres, was established on Septem The Cascade Range Forest Reserve was created on the same day. Whereas the other reserves were small in size, the Cascade Range Forest Reserve encompassed 4,, acres and was miles in length, the largest forest reserve in the nation.

The dynamic path of recreational values following a forest fire: a comparative analysis of states in the Intermountain West Jeffrey Englin, John Loomis, and Armando González-Cabán Abstract: This analysis examines the dynamic path of recreational values following a forest fire in three different states in the intermountain western United States.

    Analysis of structural patterns and tree population dynamics in natural Douglas-fir--western hemlock stands and the application of this information in restoration thinning of plantations are proposed in this 3-year research project. This research builds upon previous work (partially supported by a previous McIntire-Stennis project), which included the first structural characterizations of. The western slope of the range is wet and cool, with 60 to inches ( to m) of precipitation per year. This produces a temperate rain forest climate in the low valleys, which then grades into montane and alpine climates on mountain slopes and ion: 10, ft (3, m).

Old-growth trees in unmanaged stands were selected because no well-distributed population of young trees, either managed or unmanaged, was available for sampling.

Only a relatively few young-growth stands were available as a result of recent, scattered, catastrophic events such as fire and windthrow.
