Freese Scale for Grassland Biodiversity (Background Summary)
To help guide our actions over time, we have developed the Freese Scale for Grassland Biodiversity, which evaluates the Reserve based on ten ecological conditions that have been most affected by human activities on lands in the APR region. The seven-point scale tracks the effects of different management decisions on ecosystem processes, such as grazing patterns, hydrology and fire. In addition to creating a common language between APR and our science partners, the Freese Scale provides our managers with a tool to measure our progress as we transition lands from a primary focus on agricultural production to a focus on biodiversity.
Annual Bison Reports
We are pleased to provide you with the annual bison report from American Prairie Reserve (APR). The APR bison population, reintroduced in 2005 after a one hundred and forty year absence from this area of the Glaciated Plains, is healthy and growing steadily. It is an exciting challenge to continue to provide an expanding habitat base for this increasing bison population. Due to the eventual herd size, lack of cattle genes and overall treatment as a conservation herd for the public’s enjoyment, this herd is emerging as one of the most important bison populations in North America.
BioBlitz Report and Results
On June 23-25, 2011, the American Prairie Reserve held their first BioBlitz. In just 24 hours a list of 550 species was created by approximately 70 scientists, college students, citizen scientists and volunteers. The number of documented species was only limited by the number of taxonomic experts we could get to join this project in such a remote location. The species list will serve as a benchmark of the biodiversity in the early years on the Reserve.
