Timber Harvest: Lower Trinity - Harvested Percent through 2000 |
|
Caption: This chart shows the percent of the total sub-watershed area that was harvested per decade within the Lower Trinity Planning Watershed. The first time period category includes data prior to 1950. The different colored bars represent the percent area harvested per decade, while the total length of the bars show the cumulative percent area harvested during the period of pre-1950 to 2000. Note that harvest areas could have been re-entered during different decades. As a whole, timber harvest was most intensive between 1950 and 1970; however, harvest activities have continued during more recent decades. Reeves et al. (1993) noted that Oregon coastal watersheds logged in more than 25 percent of their area lost diversity of Pacific salmon species. Data are from Graham Matthews and Associates Trinity River Sediment Source Analysis (2001). No data from USFS (Six Rivers National Forest) or Hoopa Reservation harvests since 1977 were included in Lower Trinity. See Info Links for more information.
