AUTHORS: Bryan Burroughs, Michigan Trout Unlimited

ABSTRACT: As other symposium presenters will address in detail, the role of beaver and riparian management along trout streams is multi-faceted, presenting both opportunities and threats; the latter of which are abundant when considering Midwest trout stream hydrology and fluvial geomorphology.  In recent times, recreational beaver trapping activities has become minimal, which has lead to long-term establishment of high abundance beaver colonies, and extensive beaver dam complexes.  In these situations, the negative impacts to trout stream management goals increase, and the resources required to ameliorate these impacts and restore trout streams dramatically increase.  Michigan Trout Unlimited is increasingly encountering these conditions, and has gained several recent experiences with addressing these restoration challenges.  The numerous stream temperature, aquatic organism connectivity, and stream morphology impacts will be overviewed.  Water temperature usually increases as the dam complexes cumulatively act to increase solar warming of the waters, upstream and downstream essential available fish habitats are disconnected, and sedimentation of the stream channel results from several mechanisms, leaving an overly wide and shallow river channel.  This talk will also overview the restoration efforts that must be undergone sequentially, to address these impacts.  These include active beaver trapping and removal, wood debris installation via brush bundling and strategic large wood placement, and sequential dam breaching done to manage fine sediment transport, sequestration and retention, as well as channel incision goals.  The case of well-established beaver colonies and beaver dam complexes, represents a common scenario that can result from diminished beaver trapping and riparian management strategies, and presents a high level of negative impact to trout streams and trout population management.  The effort required to ameliorate these conditions is extensive, and illustrates a specific important consideration in the balance of beaver, trout and riparian management.
