The interrelationship between trees and humans is primordial. As pressures on natural resources grow and become more complex this innate connection drives an increased need for improved data and analytical techniques for assessing the status and trends of forests, trees, their products, and their services. Techniques for using readily available data such as the Forest Inventory and Analysis (FIA) database and output from forest disturbance detection algorithms derived from Landsat data, such as Vegetation Change Tracker (VCT), for estimating forest attributes across time from the state and inventory unit level down to the stand and pixel level are presented. Progressively more comprehensive harvest and parcel boundary records are incorporated appropriately. Quantification of attributes, including non-timber forest products and fine-scale age estimates, across the landscape both historically and into the future is emphasized. Spatial information on the distribution of forest resources by age-class provides knowledge of timber volume through time and across the landscape to support forest management for sustained production. In addition to monitoring forest resources in regards to their value as products for human consumption, their measurement facilitates analysis of the relationship of their spatial and temporal abundance to other resources such as water and wildlife. / Ph. D. / In response to growing, complex pressures on natural resources, techniques for improving the timely estimation of the status and trends of forest resources across wide regions are presented. Methods for processing large amounts of readily available data, such as U.S. Forest Service Forest Inventory and Analysis data, and forest disturbance maps derived from remotely sensed data, are used for estimating forest attributes across time by region, state, county, and individually owned forest units. The inclusion of progressively more comprehensive harvest timing and parcel boundary records improves the accuracy of regionwide wall-to-wall and spatially precise forest age and harvest boundary maps at the individual stand level. In addition, region-wide quantification of tree-based non-timber forest products is facilitated by inventory measurements that are already used for timber products. These metrics can be used to measure forest resource supplies and attributes historically and for decision-support in maintaining sustainable production into the future. Monitoring and forecasting the abundance and attributes of these forest resources with spatial and temporal precision is also valuable for analysis of their relationship to other resources such as water and wildlife.
