The Local Environmental Observer (LEO) Network is run by the Alaska Native Tribal Health Consortium (ANTHC), and is comprised of local experts who share their knowledge and experiences to describe environmental events in their communities. They apply local and traditional knowledge and modern technology to share their observations and raise awareness about the changing conditions of the circumpolar north. LEOs are connected with technical experts to increase communication and understanding about our changing environment. Observations are then mapped using and interactive interface on the ANTHC website. Tribal environmental staff participating in the LEO Network’s Community Camera Project were trained on the installation and use of time lapse cameras installed in Koliganek, Ekwok and New Stuyahok. LEO is also helpful for monitoring sea ice and shoreline change.
