A number of potential weaknesses are identified and some general recommendations for improvement are made. Special emphasis is placed on an evaluation of the methods used in Pests of Young Stands (POYS) surveys, conducted by Forestry Canada as part of the Forest Insect and Disease Survey (FIDS) program.
