their ability to "control the area",
conservation of time, and just plain "outsmarting
Graphs below are based on the Boswell Matsutake
Studies. Variations in correlation are attributed
to harvester error, or error in monitoring design.
Number one production is compared with daily temperature
variation, hi - low.
Additional, on site, variables include:
Those individual mushrooms, or patches, which receive
direct sun, mature faster.
Note: Zero days are
days of no picking
Temperatures vary on North aspects much less than South.
