The Interlake region of Manitoba is a unique landscape in Canada and possibly the world. It is underlain by soft limestone and dolomite bedrock, often exposed and strongly modified by glaciation. It is in this region that most of Manitoba’s caves are found. There are three main cave types: crevice caves, wave-cut caves and solution or groundwater-caused caves. The latter are the longest and most complex, and are where the majority of bat hibernacula are found. This workshop will cover how the caves and other karst landscape features are formed, where to find them in the province and the natural history of the three species of bats that overwinter in the caves, with emphasis on the most common, the little brown bat.
