Many other quantitative factors must also be integrated into the evaluation including: population dynamics, biology, life history, ecology, changes in habitat, threats, population viability analysis and risk assessments. Status evaluation is an evolving process and constantly requires incorporation of the latest scientific methods regarding these factors.
We will present and discuss an overview and flow chart of some of the factors and methods needed for an evaluation of the status of a threatened species. This overview is based on a decade of involvement and on-going research and assessment of the threatened Bliss Rapids snail, Taylorconcha serpenticola, in the Snake River basin, Idaho.
