TITLE: The Development of Statistical Sampling Methods for Forest Inventory
ABSTRACT:
The advancement of statistical methods for the accurate assessment
of forest resources can be traced back to the middle of the nineteenth
century in central Europe and Scandinavia. In the United States, a legal
mandate for a comprehensive and ongoing survey of timber supplies was passed
by the 1928 congress. In response the U.S. Forest Service instituted a
program of scientifically defensible statistical samples that have evolved
and expanded to include multitudes of forest resources and estimators of
current status as well as trend. This talk will describe this evolution
of increasingly sophisticated sampling strategies within the forestry profession,
including large regional surveys by public agencies as well as more focused,
industrial surveys. It will also touch on the inferential basis customarily
used in forestry, the recent emphasis on forest health monitoring and changeover
to annualized surveys
