The knowledge assessment for prioritization of conservation actions <br />considers what is known for a species in each 8-digit HUe with a potential project identified. <br /> <br />Known = 1 <br />Known = 1 <br /> <br />Unknown = 0 <br /> <br />Unknown = 0 <br /> <br />5 <br /> <br />o <br /> <br />The next step, risk assessment, is composed of six considerations with a total possible score of 14 <br />and a minimum score of 0 (Table 3-2). In this system, highest priority is given to 8-digit HUCs with <br />the greatest risk to persistence of three species, with declining and limited numbers of three species <br />populations, with less native diversity, and a higher degree of hybridization with non-natives. Lower <br />scores indicate lower risk and only the eight-digit HUCs in the management units with the highest <br />risk assessment score will move on to the opportunity assessment. If prioritization is performed at the <br />4-digit HUe level and a smaller area within the HUC is known to have a higher risk assessment <br />score than the total of the unit, that smaller stream can be broken out separately for opportunity <br />assessment. <br />
