Northwest Forestry services has inventoried over one million acres of forestland. Properties range from a few acres to 30,000 acres or larger. Inventories have been conducted for both private and public owners.
Northwest Forestry Services has completed hundreds of appraisals of timber, reproduction, and/or forestland. In addition to the economic analysis, the typical appraisal report includes much of the same information as an inventory.
Northwest forestry services produces forest cover maps using ArcGIS software. Aerial photography, lidar imagery, topographic contours, locational data, and other available data is used to produce an accurate and useful property map.
We consult on long-term feasibility of timber production and testify on the accuracy of timber appraisals and forest management practices.
Northwest forestry services have inventoried over one million acres of forestland. Properties range from a few acres to 30,000 acres or larger. Inventories have been conducted for both private and public owners. A forest inventory generally is compiled by performing a timber cruise. In a timber cruise, a forest stand is measured to determine the quantity and quality of forest products that can be derived from it. In addition to timber quantity and quality, a cruise often contains information about species composition, age, tree health, site quality, topography, and operability for logging. It also can include data on growth, down woody material, snags, understory vegetation, and other resources. Items included in an inventory report are listed below:
An appraisal includes the following information:
Northwest forestry services produces forest cover type maps using ArcGIS software. Aerial photography, lidar imagery, topographic contours, locational data collected with a global positioning system (GPS), and other available data are input into the software in order to produce an accurate and useful property map. The resulting digital map then can be used to calculate and to visualize such features as acreage by cover type, average slope, age class distribution, and others.
