1/5. #WBTC1 #Conserve3. I’m Rob Schorr @ColoradoStateU. When WNS hit eastern NAmer, #bats mortality was obvious. When WNS hit western NAmer, mortality was much less obvious. Fewer cave/mine hibernacula in the West. Where should biologists monitor ? Maybe cliffs!

2/5. #WBTC1 #Conserve3 Climbers for Bat Conservation is a collaboration among #climbers, biologists, and land managers ( @SOGES_CSU, @accessfund, @USFWS, @petzl_fondation, @COParksWildlife, @WGFD) to understand where bats roost and where populations might be.

3/5 #WBTC1 #Conserve3 Climbers see in natural rock roosts. Currently 70 records from 12 states, UK, Bulgaria, Norway. Most are of single , but a few of 100s and 1000s of bats. We now have climbers as surveyors and ambassadors for conservation.

4/5 #WBTC1 #Conserve3 What if you hire climbers to look for bats? 50 km W of Denver, Colorado, USA. Pre-climbing surveys and climbing surveys. 42 pre-climb surveys, 45 climbing. 2 found: Myotis evotis, Eptesicis fuscus. 1cm cracks, east-facing, 10–12m high

5/5 #WBTC1 #Conserve3 Next steps: online data portal for data submission; visit routes where climbers have seen ; engage with climbers at festivals and show them bats; and collaborate with climbing orgs! See a while climbing, let us know! email: [email protected]
