DescriptionHabitat loss and fragmentation are threats to persistence of many native fish populations. Invading nonnative species that may restrict or displace native species are also important. These two issues are particularly relevant for native salmonids that are often limited to remnant habitats in cold, headwater streams. On the surface, reversing threats to native fishes would seem to be straightforward: focus all available resources on habitat restoration and control of invaders. However, there are trade-offs that make this a more complex problem. This is well illustrated by the installation or removal of barriers to fish movements because either action may simultaneously mitigate and exacerbate risks to native salmonid populations.
