Estimating forest conversion rates with annual forest inventory data

The rate of land-use conversion from forest to nonforest or natural forest to forest plantation is of interest for forest certification purposes and also as part of the process of assessing forest sustainability. Conversion rates can be estimated from remeasured inventory plots in general, but the emphasis here is on annual inventory data. A new estimator is proposed based on analysis of plot-l...

Regression Analysis for Forest Inventory Data

In this paper the data of a forest health inventory are analysed. Since 1983 the degree of defoliation (damage), together with various explanatory variables (covariates) concerning stand, site, soil and weather, are recorded by the second of the two authors, in the forest district Rothenbuch (Spessart, Bavaria). The focus is on the space and time dependencies of the data. The mutual relationshi...

Integration of Lidar, Landsat Etm+ and Forest Inventory Data for Regional Forest Mapping

Recent work has established the utility of waveform sampling lidar for predicting forest structural attributes. Nevertheless, serious obstacles to its wide-spread use still exist. They include the lack of waveform sampling lidar sensors capable of measuring forest canopy structure over large extents, and the practical difficulty of developing widely applicable relationships to predict forest st...

The Enhanced Forest Inventory and Analysis Program of the USDA Forest Service: Historical Perspective and Announcement of Statistical Documentation

among state and federal agencies. The FHM program focuses on assessing and monitoring the health and sustainability of the nation’s forests and consists of four primary activities: detection monitoring, evaluation monitoring, intensive site monitoring, and research on monitoring techniques. Together, these four activities permit predictions of where and how future ecosystems might change under ...
