Topic	Timber Harvest: Upper Trinity - Harvested Area through 2000

 

	This is a map of timber harvest from pre-1950 to 2001 in the sub-watersheds of the Upper Trinity Planning Watershed, displayed with Trinity River and sub-basin outlines. Timber harvest was most intensive from 1950 to 1970, but has continued during more recent decades. No data from USFS (Six Rivers NF) or Hoopa Reservation harvests since 1977 were included in Lower Trinity. Data were produced by the Trinity County Resource Conservation District for the Graham Matthews and Associates Trinity River Sediment Source Analysis (2001).
