TCC Sentinel
Read full descriptionHide full description
The TCC Sentinel app is for community-based observers and local and traditional knowledge holders to record environmental observations in their local landscapes.The TCC Sentinel Community-Based Monitoring Program is part of the Indigenous Sentinels Network (ISN) family of apps which have been designed and refined over the past 15 years in Alaskan Native communities. Users of the TCC Sentinel app are located primarily in remote environments. Communities are better able to actively participate and lead data collection that both addresses community concerns and contributes meaningful data to researchers, resource managers, and decision makers. ISN Community-Based Sentinel Monitoring Programs are established using observation protocols and standardized methodologies for community-based recording of observations of wildlife, subsistence species and environmental impacts at locations surrounding participating communities. These data, if collected in a repeatable and consistent manner over time, can provide valuable environmental reference points for the region. For information on joining the Indigenous Sentinels Network please contact the Aleut Community of St. Paul Tribal Government.
