Northwest Forest Plan - Land Use Allocations:

A central component of the NW Forest Plan was the creation of a regional set of of land allocations, each with associated management standards and guidelines. The reserve network was primarily designed to meet the habitat requirements of the northern spotted owl, marbled murrelet, and salmon species.

The Late-Successional Reserve (LSR) Work Group conducts reviews of proposed actions in LSRs to ensure that these are consistent with the requirements of the Northwest Forest Plan.

An archive of information on the Adaptive Management Areas network is also available.

Land Allocation	Original Acres	Percentage	Description
Congressionally Reserved Areas	7,320,600	30	Lands reserved by the U.S. Congress such as wilderness areas, wild and scenic rivers, and national parks and monuments.
Late-Successional Reserves	7,430,800	30	Lands reserved for the protection and restoration of LSOG forest ecosystems and habitat for associated species; including marbled murrelet reserves (LSR3) and northern spotted owl activity core reserves (LSR4).
Managed Late-Successional Areas	102,200	<1	Areas for the restoration and maintenance of optimum levels of LSOG stands on a landscape scale, where regular and frequent wildfires occur. Silvicultural and fire hazard reduction treatments are allowed to help prevent older forest losses from large wildfires or disease and insect epidemics.
Administrative Withdrawn Areas	1,477,100	6	Areas identified in local forest and district plans; they include recreation and visual areas, back country, and other areas where management emphasis does not include scheduled timber harvest.
Adaptive Management Areas–reserved	AMA combined:		Identified to develop and test innovative management to integrate and achieve ecological, economic, and other social and community objectives. Emphasis on restoration of late-successional forests and managed as an LSR.
Adaptive Management Areas–nonreserved	1,521,800	6	Identified to develop and test innovative management to integrate and achieve ecological, economic, and other social and community objectives. Some commercial timber harvest was expected to occur in these areas, but with ecological objectives.
Riparian Reserves	2,627,500	11	Protective buffers along streams, lakes, and wetlands designed to enhance habitat for riparian-dependent organisms, provide good water-quality dispersal corridors for terrestrial species, and provide connectivity within watersheds.
Matrix	3,975,300	16	Federal lands outside of reserved allocations where most timber harvest and silvicultural activities were expected to occur.

Updates

The geographic information system (GIS) layer representing these LUAs was originally delineated during the analysis for the NWFP (USDA and USDI 1994). The LUA GIS layer is updated every 5 years as part of the monitoring reporting cycle.

Update	Summary Description
20-year	The 2013 update mainly involved addition of congressionally reserved allocations (364,000 ac) as a result of a few new wilderness designations since the 15-year report. Other updates included land exchanges and acquisitions as well as minor editing to correct errors and clean up map features. About 71,000 ac remain without assigned allocations, which are attributed as “no data” (ND). Overall, there was a slight increase in federal lands (1.5 percent) with a 0.4 percent increase in reserved land use allocations.
15-year	The LUA map layer and Plan boundaries were slightly modified since publication of the 10-year report to correct minor errors and incorporate changes in LUA and federal land boundaries. This involved acquiring and assimilating the most up-to-date ownership layers from a wide variety of land owners within the NWFP area. Effort was made to resolve slivers and gaps that existed between adjacent ownerships, often relying on Digital Raster Graphics (DRGs) of 1:24,000 scale USGS quadrangles to determine boundary locations. The difference in total area between the 10-year report and the 15-year report is about 1 percent.
10-year	A 2002 update to the original NWFP LUA map involved the following: provided better boundaries for these allocations based on subsequent work by individual forests, adjusted incorrect interpretations of NWFP direction presented in earlier maps, and; updated the map for any changes in land allocation decisions that have occurred subsequent to the Record of Decision.
Original	The original NWFP LUA GIS layer was developed from Option 9 of the Forest Ecosystem Management Assessment Team (FEMAT 1993).
