Fine organic debris and dissolved oxygen in streamed gravels in the Oregon Coast Range

Creator:

Skaugset, Arne E.

Abstract:

Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six...

Historical disturbance regimes as a reference for forest policy

Creator:

Thompson, Jonathan R.

Abstract:

Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is thought that forest management can produce forest composition and structure similar to the conditions that once supported the native biota....

Recruitment trends and physical characteristics of course woody debris in Oregon Coast Range streams

Creator:

Heimann, David C.

Abstract:

This study investigated the long-term consequences of timber stand removal on the recruitment, physical characteristics, and spatial distribution of coarse woody debris in small (second- and third-order) streams of the Oregon Coast Range. A chronosequence of stream-stand systems, ranging from 21- to 140-years since disturbance (YSD), were sampled to determine...
