CEC’s work to support the Local Environmental Observer (LEO) Network (2015–2016)

Long-term Impact Assessment

November 30, 2025 7 pages Ecosystems

The Local Environmental Observer (LEO) Network is an online community of local observers and topic experts who share knowledge about unusual animal, environment, and weather events. The Network originated within the Alaska Tribal Health System as a project of the Alaska Native Tribal Health Consortium (ANTHC) in 2012 to bring local area experts in rural communities into contact with topic experts who might be far away.

Through LEO, members can share observations, connect on various topics with experts from different knowledge backgrounds—local, Indigenous, and scientific—help detect emerging environmental concerns in their communities and engage in a range of observer and citizen science opportunities. The Network aims to increase understanding of environmental change and help identify healthy and effective ways to adapt to it.
