Ralph E. Williams; C. D. Leaphart Canadian Journal of Forest Research 1978. doi:10.1139/x78-033
Other claims from this paper (6)
- Observation An estimated 5.1% (12 160.7 ha) of commercial forest land was occupied by root disease infection centers.
- Observation Root disease centers were identified in 113 of 364 surveyed stands.
- Observation Most of the 113 stands with root disease were of the Tsugaheterophylla – Pachistimamyrsinites habitat type.
- Association Occurrence of Pseudotsugamenziesii, Abiesgrandis, or both in a stand is the most important factor in the expression of root disease centers.
- Method / resource Accuracy of photo interpretation for root disease centers was 92%.
- Association Incorrect interpretations were associated with stands in the Abieslasiocarpa series of habitat types or with stands stocked with conifers tolerant of root pathogens.
