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...

Evaluating a new method for reconstructing forest conditions from General Land Office survey records

Historical forest conditions are often used to inform contemporary management goals because historical forests are considered to be resilient to ecological disturbances. The General Land Office (GLO) surveys of the late 19th and early 20th centuries provide regionally quasi-contiguous data sets of historical forests across much of the Western United States....

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...

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...

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.

Landscape-scale fuel treatment and wildfire impacts on carbon stocks and fire hazard in California spotted owl habitat

Forest managers are challenged with meeting numerous demands that often include wildlife habitat and carbon (C) sequestration. We used a probabilistic framework of wildfire occurrence to (1) estimate the potential for fuel treatments to reduce fire risk and hazard across the landscape and within protected California spotted owl (Strix occidentalis...

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...

Estimating ladder fuels: a new approach combining field photography with LiDAR

Forests historically associated with frequent fire have changed dramatically due to fire suppression and past harvesting over the last century. The buildup of ladder fuels, which carry fire from the surface of the forest floor to tree crowns, is one of the critical changes, and it has contributed to uncharacteristically large and severe fires. The abundance of ladder...
