A ground survey method for estimating loss caused by Phellinus weirii root rot. I. Development of survey design. II. Survey procedures and data analysis


, : A ground survey method for estimating loss caused by Phellinus weirii root rot. I. Development of survey design. II. Survey procedures and data analysis. [Report] Pacific Forest Research Centre, Canada (BC-R-3; BC-R-4): 24 ; 44

I. Two sampling methods based on transect lines are developed for estimating total P. weirii root rot area in simulated Douglas fir stands, based on (a) the total length of transect lines in a random grid falling within infection centres - the intersection length method or (b) the probability of encountering infection centres along transect lines - the probability of occurrence method. Method (b) can also be used to estimate area and numbers of infection centres by size class.
