Its purpose is to collate records of fungi, plant pathogens, and plant-associated microorganisms occurring on native plants and other forest substrates in British Columbia. The Index holds records of 3506 organisms on 1703 different plant hosts and other substrates. Of these records, 4742 are verified by herbarium specimens curated at the Pacific Forestry Centre. A separate, incomplete list of organisms associated with some agricultural crops and introduced ornamental plants (included in an earlier host-fungus index but not updated) is also appended.

In an experiment made under ambient (summer-fall) temperatures in a shadehouse at Victoria, British Columbia, Canada, 8 of the 22 conifer species were killed by the nematodes, but mortality was low, i.e. 4-30%. Pines (eastern white, Jack and red) were more susceptible than other conifers. Yellow cypress, eastern white cedar, western red cedar and western hemlock were not killed by the nematodes. In a second experiment made at elevated temperatures (30°C-16 h long days, 25°C-8 h long nights) in a greenhouse, 18 of the 22 conifer species died following nematode inoculation. Again, pines (lodgepole, eastern white, western white and red) were among the most susceptible tree species and the four conifers that were unaffected in the first experiment were not killed. Tamarack and western larch, both immune at ambient temperatures, were the two most susceptible conifers at elevated temperatures. Compared to ambient temperatures, seedlings at elevated temperatures died quicker and contained more nematodes. M and r form nematodes were equally pathogenic in both experiments.
