Centennial Valley Arctic Grayling Adaptive Management Project 2017 Factsheet

The Centennial Valley Arctic Grayling Adaptive Management Plan (AMP) is being implemented to identify the most effective management strategies to maintain at least 1000 spawning fish in the upper CV grayling population. Non-native hybrid Yellowstone cutthroat trout, spawning habitat, and overwinter habitat have been identified as the three most likely factors that could limit long-term viability of upper CV grayling. A population model representing each hypothesized limiting factor was created; learning occurs through the comparison of annual model predictions of grayling abundance to estimated grayling abundance.

This factsheet summarizes the goal, approach, and outcomes for 2017.
