Assessing whether Japanese National Forest Inventory Plots Were Re-measured:

Re-Measured Relascope Plots in the Assess- ment of Inventory Update Methods

For the monitoring of forest ecosystems, there is often a need to survey element of importance for threatened species or populations of some indicator species. Such populations are often sparse and scattered and, hence, inventories tend to be expensive. To improve the efficiency of such surveys a new method, guided transect sampling, has been proposed. The method use prior information w...

Forest inventory and analysis: a national inventory and monitoring program.

Forests provide significant commodity and noncommodity values to the citizens of the United States. An important and substantial role in ensuring the continued health, productivity, and sustainability of these resources is a reliable and credible inventory and monitoring program. The Forest Inventory and Analysis (FIA) program of the US Forest Service has been monitoring and reporting on status...

Trend analyses and projections using national forest inventory data

We present a collection of papers derived from the 2012 Forest Inventory and Analysis (FIA) Symposium held on December 4-6, 2012 in Baltimore, MD, USA. The symposium featured 128 oral presentations with nearly 200 attendees from the United States and other countries. A proceedings from the symposium included 75 papers as well as abstracts for all presentations and posters. The symposium theme, ...

Statistical Properties of Alternative National Forest Inventory Area Estimators

The statistical properties of potential estimators of forest area for the USDA Forest Service’s Forest Inventory and Analysis (FIA) program are presented and discussed. The current FIA area estimator is compared and contrasted with a weighted mean estimator and an estimator based on the Polya posterior, in the presence of nonresponse. Estimator optimality is evaluated both theoretically and via...
