Revised estimates for direct-effect recreational jobs in the interior Columbia River basin.

This paper reviews the methodology used to derive the original estimates for direct employment associated with recreation on Federal lands in the interior Columbia River basin (the basin), and details the changes in methodology and data used to derive new estimates. The new analysis resulted in an estimate of 77,655 direct-effect jobs associated with recreational...

Application of QuickBird imagery in fuel load estimation in the Daxinganling region, China.

A high spatial resolution QuickBird satellite image and a low spatial but high spectral resolution Landsat Thermatic Mapper image were used to linearly regress fuel loads of 70 plots with size 30X30m over the Daxinganling region of north-east China. The results were compared with loads from field surveys and from regression estimations by surveyed stand characteristics...

Estimated timber harvest by U.S. region and ownership, 1950-2002.

This publication provides estimates of total softwood and hardwood harvests by region and owner for the United States from 1950 to 2002. These data are generally not available in a consistent fashion and have to be estimated from state-level data, forest resource inventory statistics, and production of forest products. This publication describes the estimation process...

Estimating ecological integrity in the interior Columbia River basin.

The adoption of ecosystem-based management strategies focuses attention on the need for broad scale estimates of ecological conditions; this poses two challenges for the science community: estimating broad scale ecosystem conditions from highly disparate data, often observed at different spatial scales, and interpreting these conditions relative to goals such as...

Sampling considerations for establishment of baseline loadings from forested watersheds for TMDL application

Five methods for estimating maximum daily and annual nitrate (NO3) and suspended sediment loads using periodic sampling of varying intensities were compared to actual loads calculated from intensive stormflow and baseflow sampling from small, forested watersheds in north central West Virginia to determine if the less intensive sampling methods were accurate and could...

Wildland fire probabilities estimated from weather model-deduced monthly mean fire danger indices

The National Fire Danger Rating System indices deduced from a regional simulation weather model were used to estimate probabilities and numbers of large fire events on monthly and 1-degree grid scales. The weather model simulations and forecasts are ongoing experimental products from the Experimental Climate Prediction Center at the Scripps Institution of Oceanography...

Estimating postfire water production in the Pacific Northwest

Two hydrologic models were adapted to estimate postfire changer in water yield in Pacific Northwest watersheds. The WRENSS version of the simulation model PROSPER is used for hydrologic regimes dominated by rainfall: it calculates water available for streamflow onthe basis of seasonal precipitation and leaf area index. The WRENSS version of the simulation model WATBAL...

A process to establish and use base period prices for national forest system transaction evidence timber appraisal

The USDA Forest Service is required to appraise timber prior to it being offered for sale. Currently the Forest Service uses a transaction evidence based approach, but concerns have been raised about availability?both in number and applicability?of timber sales used as the basis of this approach. In addition to the problem of few sales, in certain situations a notable...

Estimating postfire changes in production and value of Northern Rocky Mountain-Intermountain rangelands

A simulation model was developed to estimate postfire changes in the production and value of grazing lands in the Northern Rocky Mountain-Intermountain region. Ecological information and management decisions were used to simulate expected changes in production and value after wildfire in six major rangeland types: permanent forested range (ponderosa pine), transitory...

Seasonal and among-stream variation in predator encounter rates for fish prey

Recognition that predators have indirect effects on prey populations that may exceed their direct consumptive effects highlights the need for a better understanding of spatiotemporal variation in predator?prey interactions. We used photographic monitoring of tethered Rainbow Trout Oncorhynchus mykiss and Cutthroat Trout O. clarkii to quantify predator encounter rates...

Timber harvests in Alaska: 1910-2006

This publication provides estimates of total softwood harvest, by owner, for Alaska for 1910-2006. This information is a mix of reported and estimated data. These data are being used to develop assumptions needed in forest planning by both public and private forest managers.

Estimated economic impacts on the timber range and recreation programs on NFS and BLM public lands from adopting the proposed interim PACFISH.

Implications of the interim comprehensive strategy for improved Pacific salmon and steelhead habitat management (PACFISH) were estimated for those Bureau of Land Management (BLM) districts and National Forest System (NFS) lands west of the Rocky Mountains that have anadromous fish. The physical impacts and associated mitigation costs from implementing the PACFISH...

The 1993 timber assessment market model: structure, projections, and policy simulations.

The 1993 timber assessment market model (TAMM) is a spatial model of the solidwood and timber inventory elements of the U.S. forest products sector. The TAMM model provides annual projections of volumes and prices in the solidwood products and sawtimber stumpage markets and estimates of total timber harvest and inventory by geographic region for periods of up to 50...

Spatial allocation of market and nonmarket values in wildland fire management: A case study

We developed a methodology to evaluate the efficacy of fuel treatments by estimating their costs and potential costs/losses with and without treatments in the San Jacinto Ranger District of the San Bernardino National Forest, California. This district is a typical southern California forest complex containing a large amount of high-valued real estate. We chose four...
