Forest Biometrics Exam 1 UPDATED Exam
Questions and CORRECT Answers
This course will concentrate on two areas: - CORRECT ANSWER - Sampling and
Estimation
Growth and Yield
Sampling is - CORRECT ANSWER - a method or process that allows an estimation to be
generated to describe a population
why dont we measure all the trees in an area? - CORRECT ANSWER - Measuring an
entire population is time consuming and in most cases cost prohibitive
Sampling, if done correctly, can provide a - CORRECT ANSWER - cost effective and
accurate method for effective decision making for natural resource managers
there is a direct correlation between costs and - CORRECT ANSWER - information
quality
To determine the quality of sampling and estimation we will use - CORRECT ANSWER -
statistics for validation
For a forester, the sampling and estimation process is called - CORRECT ANSWER -
forest inventory
2 most common reasons to do a forest inventory - CORRECT ANSWER - gather info for
-management
-timber sales
, The intensity of a forest inventory results in an estimation of the - CORRECT ANSWER -
-whats out there
-how much is out there
-where is it
the higher the intensity of an inventory, the greater the - CORRECT ANSWER - accuracy
Inventory Objectives can include - CORRECT ANSWER - Volume or value or both of
timber in a defined spatial extent
Number of deer per spatial unit
Habitat quality for a wildlife species
Occurrences of other species (vegetative or animal)
Fuel Load Modeling
Road characteristics and integrity
Soil analysis
Two types of Sampling: - CORRECT ANSWER - Subjective and Probability
subjective sampling - CORRECT ANSWER - can be implemented with or without
preconceived bias
what does biased sampling mean - CORRECT ANSWER - conscious avoidance of forest
stand nonconformities i.e. only pick plots that seem to represent the entire stand that can leave
out nonaverage characteristics
what does non-biased sampling mean - CORRECT ANSWER - inclusion of forest
conditions that include areas considered extremes (min/max) of the population i.e. small/large
