||Timber Harvest: Matthews Harvested Percent, Headwater Basins 1921-2000
||Caption: The chart above shows the percent of total basin area harvested by period in Big River Headwater sub-basins between 1921 to 2000. Martin Creek and the Upper Mainstem were harvested over 50% in the most recent period (1989-2000). Some sites may have been entered more than once so the extent of land area disturbance may be slightly over-estimated. Reeves et al. (1992) noted that Oregon coastal watersheds logged in more than 25% of their area lost diversity of salmonid species. See Info Links for more background information and links to references.
