Assessment of Abandoned Mines for Bat Use on Bureau of Land Management Lands in the Phillipsburg, Montana Area, 1999

Book Description
In July 1999, three groups of abandoned mine workings on BLM lands in the Philipsburg, Granite County, Montana area were inspected for their potential use by bats. Site groups included the Russian Gulch Mine (2 adits), Frost Creek group adjacent to Philipsburg (5 adits), and the Cliff Creek group, also adjacent to Philipsburg (7 adits, 1 shaft). Where possible, workings were inspected internally for bats and bat spoor; at sites suitable and with greatest potential, mist nets were set across portals and monitored for two hours after sunset. All but the Russian Gulch Mine were shallow workings or inaccessible, and all workings exhibited low activity or low potential for significant use by bats. The Russian Gulch Mine could be made more accessible to bats, and has the greatest potential for significant use, but another nearby working (Silver King Mine) showed current bat activity (as of 1997) and is preferable for bat-friendly reclamation if limited funds preclude management for bats at both mines. Five bat species that use caves and mines as primary hibernation habitat have been recorded from Granite County, and have the potential to occur in abandoned mine workings in the Philipsburg area. These species include the Western Small-footed Myotis (Myotis ciliolabrum), Western Long-eared Myotis (M. evotis), Little Brown Myotis (M. lucifugus), Long-legged Myotis (M. volans) and the Townsend Big-eared Bat (Corynorhinus townsendii). All but the Little Brown Myotis are U.S. Fish and Wildlife Service Special Concern species, and the Townsend Big-eared Bat is also a BLM Special Status species in Montana.

Assessing the Stability and Long-term Viability of Abandoned Mines for Use by Bats

Book Description
There are 12 species of bats that occur in Illinois; 5 of these species can be found hibernating in abandoned mines and caves in southern Illinois. Due to the destruction of their natural hibernacula, caves, many species of bats have found abandoned mines to be suitable replacement habitat. A complex of abandoned underground microcrystalline silica mines in southern Illinois owned by Unimin Specialty Minerals Corporation now provides hibernacula for 5 species of cavernicolous bats: the federally endangered Indiana bat (Myotis sodalis), little brown bat (M. lucifugus), eastern pipistrelle (Perimyotis subflavus), big brown bat (Eptesicus fuscus), and the northern long-eared bat (M. septentrionalis). Within the last 10 years the number of bats using these mines has increased dramatically, especially the Indiana bat which has increased from just over 9,000 to 43,000 hibernating in Magazine Mine. One concern of having so many endangered bats hibernating in one mine is stability. Mines were created relatively recently and are still in the process of settling. Thus, these mines might act as a potential sink, drawing in hibernating bats but potentially collapsing and killing them. Thirteen mines were surveyed for bats and for the amount of spalling that occurred over the 16-month study period from September 2006 to December 2007. Factors that could increase the amount of spalling were quantified, including temperature, moisture, and moisture variability in the material of the walls in the mines, and temperature variability. Number of hibernating bats in the mines was also documented. Data were analyzed with logistic regression. Temperature was a significant predictor of spalling (W2 = 12.76, p = 0.0004) when considered as a univariate variable, as was temperature variation (W2 = 21.89, p =
