Sierra Nevada Avian
Monitoring Information Network


Welcome to SNAMIN

The Sierra Nevada Avian Monitoring Information Network (SNAMIN) is an interactive website intended for use by natural resource managers and other stakeholders across the Sierra Nevada to help inform adaptive management decisions. This site provides easy access to avian monitoring data from across the Sierra Nevada, allowing users to quickly and easily generate summary, abundance, occupancy, and species richness analyses for over 100 bird species. Results can be generated from the scale of individual transects, to sets of multiple transects within forest service ranger districts, National Forests, or the entire bioregion.

There are mapping tools for visualizing the spatial distribution of survey locations and presence/absence of species at those locations and links to raw data. As new data are collected they are made available on the website within a few months. Currently SNAMIN provides access to data from multiple Point Blue avian monitoring projects including: Sierra-wide bioregional Management Indicator Species (MIS) project targeting the habitats of Hairy Woodpecker, Mountain Quail, Fox Sparrow, and Yellow Warbler; as well as aspen, meadow, and fuels treatment monitoring projects in the Northern Sierra. In addition, SNAMIN provides access to Sierra Nevada relevant avian monitoring resources including recent publications, reports, and white papers.
