Protecting Native Aquatic Ecosystems
Invasive species pose a severe threat to wild salmon and native freshwater ecology in West Cook Inlet. TTCD leads proactive surveillance, early detection, and rapid response initiatives across the 6.6-million-acre District.
Key Focus Areas
- Elodea Eradication: Successfully treated floatplane and salmon lakes in the Tyonek area, completely removing invasive Elodea to restore native aquatic vegetation.
- Northern Pike Control: Implementing targeted suppression netting in Alexander Creek to mitigate pike predation on juvenile salmon smolt.
- Community Early Detection: Educating pilots, boaters, and local residents to spot invasive plants and report sightings early.

🐊 Invasive Northern Pike vs. Wild Salmon Impact Estimator
Invasive Northern Pike prey heavily on juvenile Coho and Chinook salmon smolt in shallow lakes. See how TTCD's gill-netting suppression increases wild salmon survival.
