CLIMATE CHANGE AND CUTTHROAT TROUT CONSERVATION IN THE SOUTHERN ROCKY MOUNTAINS: THE PARADOX OF CONNECTIVITY
Mountain streams and lakes are important refuge habitats for native fishes and are influenced by climate change through shifting thermal and hydrological regimes. Cutthroat Trout (CT; Oncorhynchus clarkii) in the southern Rocky Mountains (SRM) inhabit small fractions of their historic ranges and current populations are found in fragments of habitat in mountain streams and lakes. Therefore, a cornerstone of CT conservation strategies involve increasing the connectivity of stream and lake habitats (via increased stream length or habitat area) to provide greater habitat heterogeneity, thereby bolstering the resilience of CT populations. However, a tradeoff is that upstream invasion by non-native fishes also threaten persistence of CT, and a management strategy to prevent these invasions are movement barriers that intentionally fragment watersheds. These multiple stressors create the need to balance competing demands for increased connectivity with intentional fragmentation. We present results that show how SRM lakes and streams are important habitats for CT conservation, different ways these habitats are warming (e.g., SRM lakes +0.47°C·decade-1 and streams +0.17°C·decade-1), and predict persistence of CT using a framework that incorporates multiple stressors.
