We will be comparing the abundance, composition, and population dynamics of mammal species captured on the plots over the next 5-10 years. The loss and fragmentation of these habitats during recent years are thought to be the primary reasons for the squirrels' decline. The future loss of these forest habitats resulting from global warming is also a concern. We are currently conducting 2 research projects on these squirrels. One study is focused on truffles, one of the northern flying squirrels' principal food items.
Truffles are the underground fruiting bodies of mycorrhizal fungi.
We are comparing the abundance and composition of truffles in areas that support northern flying squirrels to the abundance and composition of truffles in areas where no northern flying squirrels have been found to determine whether the distribution of squirrels is related to the distribution of truffles. The other study is examining the effects of habitat fragmentation on northern flying squirrels to test whether fragmentation is really a problem and has led to their decline. Results of this study may also help managers determine which areas are most likely to support northern flying squirrels and in which areas the squirrels are most likely to go extinct.
