Trey Simmons is leading a survey of juvenile fish in streams of Wrangell-St Elias National Park and Preserve, emphasizing the importance of streams and rivers in shaping ecosystems in Central Alaska. These waterways create diverse habitats crucial for various species through gradual and dramatic landscape changes. The Central Alaska Network employs a mix of biological, chemical, and physical data gathered from both accessible and remote streams to monitor ecological changes. Key activities include documenting stream attributes, understanding temperature changes, assessing ecosystem health and water chemistry, and characterizing the hydrologic regime of the Nabesna River. This comprehensive monitoring aids park managers in maintaining ecosystem health across the vast Central Alaska Network.
