About Big Nen River Wetland Nature Reserve

 

Located in southwestern Alaska, the Big Nen River Wetland Nature Reserve encompasses a large, ecologically significant wetland complex fed by the Big Nen River and its tributaries. This reserve protects a mosaic of peat bogs, marshes, and slow-moving waterways that are critical habitats for migratory birds, waterfowl, and an array of freshwater fish species including salmon. The area supports black and brown bears, moose, and numerous smaller mammals making it a hotspot for wildlife viewing. Geography here is defined by flat, wet terrain dominated by sphagnum moss mats, sedges, and alder thickets. It also includes several raised layers of tundra, offering diverse plant communities uncommon in wetland areas. Historically, indigenous communities used the wetlands for fishing and hunting, with current management aimed at preserving traditional subsistence uses alongside ecological integrity. Recreational activities are centered around hiking narrow boardwalk trails, birdwatching, nature photography, and paddle sports such as canoeing along peaceful river sections. Visitors are drawn to the reserve for its undisturbed tranquility, rich biodiversity, and the vibrant seasonal colors that paint the landscape in late summer. While facilities are minimal to maintain the reserve’s natural state, well-marked trails and small observation platforms provide excellent vantage points for wildlife and scenic river views. The reserve’s remote location means access involves careful planning, appealing to those who seek quiet, immersive nature experiences away from typical tourist routes.
