Biological Rarity Index and Probability Value - 40 Acre Grid
Two models, a probability model and a biological rarity index model, are provided in this dataset. Both models are based on the Michigan Natural Features Inventory (MNFI) database of known sightings of threatened, endangered, or special concern species and high quality natural communities. The model values are reported on a 40 acre polygon grid for the state of Michigan, or a subset of MI.
