Using cost-plus-loss analysis to define optimal forest inventory interval and forest inventory accuracy

Forest inventory

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...

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...

Yield Frontier Analysis of Forest Inventory

Standing inventory analysis allows a forester to predict the yield (volume by logtype) of a section of forest before the trees have been felled. Current standing inventory tools such as MARVL and ATLAS Cruiser predict yield. They do this by simulating the bucking that will take place when the trees are harvested. These tools produce a point estimate of the yield for given input data. In practic...

Stratified sampling based on photo- interpreted forest types reduces the cost of strategic forest inventory

This study assesses the effectiveness of stratification, based on photo-interpreted forest types, for strategic inventory. It uses results (from stratified sampling) for Total Merchantable Volume (TMV) in 18 Inventory Areas in Tasmanian State forest. The variance of the TMV as determined from stratified sampling is compared with the estimated variance of a simple random sample using the same nu...
