Latest WNS Summary Map

This map is a slightly different version of the ubiquitous WNS map, also put together by PA Game Commission's Cal Butchkoski (thanks, Cal, for this tireless, and depressing, service). It highlights just this year's WNS reports:

Tennessee has nearly full saturation as would be expected. What is clear, is that WNS has a very difficult time moving across the country and appears that only certain periods of the year and only certain individuals transmit the Gd, possibly only while in the maternity colony!

What? On what are you basing the comment about maternity colonies? As WNS affects bats primarily during hibernation, and maternity colonies occur once the bats emerge to give birth, and these are usually very warm - well above the temperature where the fungus survives, this is simply incorrect.

Actually, I was curious about your statement Peter. Summer temps, especially ones in a maternity colony would generally be well above what GD would grow in...however, survive is a little different as is spreading spores.

Are you saying air temperature alone within a maternity colony is enough to kill GD, not just inhibit hyphae growth?
