Inhaltsangabe

Excerpt from A Spruce Budworm Sampling Program for Husky Hunter Field Data Recorders<br/><br/>The program then asks whether data will be entered via either the keyboard or a bar code, whereupon it successively loops through a routine allowing for the entry of host, branch tip length and width (in centimeters), and the number of budworms or egg masses found on the measured tip. The sampling scheme requires that two 45-centimeter tips per tree be measured before allowing the user to go to the next tree. The program also prompts the user to estimate whether budworm density on the plot will be low, medium, or high. This estimate is necessary to trigger a subroutine within the program that computes some of the plot statistics as described below. This trigger requires the entry of at least one budworm after sampling 3 trees for a high density estimate, one budworm after 7 trees for the medium-density estimate, and one budworm after 10 trees for the low-density estimate. These density levels are arbitrary and are selected only to make the program run more efficiently.
