vpsThe Variable Probability Sampling course is offered as a service to foresters. Two popular methods of timber cruising will be covered in detail: variable-plot sampling and 3-P sampling (Probability, Proportional to Prediction). The course is suitable for relative beginners as well as those with experience who like to brush up on the principles and up-to-date computation techniques using hand calculators and microcomputers. Field exercises using both techniques are an important part of the course.

Participants are invited to submit problems they have encountered in either field application or office computation in variable-plot sampling for a special session during the first part of the program. All such questions may be submitted in advance to the short course director, Dr. James Kiser, before March 1, 2018.
