Criterion 2 Indicator 10
Rationale
Area of Forest Land and Net Area of Forest Land Available for Timber Production
 
The size of the forest land base and how it is allocated are important variables that determine the mix of goods and services that come from the forest.

Can This Indicator Be Quantified
Yes. Two different sources have been used to estimate the size of the forest land base. The Oregon Department of Forestry’s Annual Report (1997) estimates the amount of timberland (land capable of producing 20 cubic feet/per acre/per year of wood) in Oregon to be about 16.3 million acres. The table below shows how much forest land there is in Oregon, and who owns it. Map 10-1 also depicts forest land in Oregon.

A geographical information system (GIS) was used to combine data layers that showed reserved forest lands, produced by the U.S. Bureau of Land Management (BLM) and U.S. Forest Service, with another data layer that showed the Oregon Department of Fish and Wildlife (ODFW) gap forest layer. The reserved categories include data from many different land use designations (see Indicators #3 and #19). The GIS analysis produces an estimate that about 35 percent of Oregon’s forest lands have some kind of restrictions on timber harvest (See Map 10-7, and Table 10-2 below).

Trends
The amount of forest land reserved from timber harvesting has increased steadily over time (See Maps 10-2 through 10-7).
