<br />Page 63 <br /> <br />· Identify threats to population persistence. <br />· Locate populations of the subject species to determine status of each. <br /> <br />2.) Establish and maintain a database of past, present, and future information on roundtail chub, <br />bluehead sucker, and flannelmouth sucker. <br /> <br />· Establish format and maintain compatible databases. Signatories have identified <br />the need to maintain a range-wide database as the primary means to conduct a <br />range-wide assessment. <br />· Establish and maintain bibliography of subjeqt species. <br /> <br />3.) Determine roundtail chub, bluehead sucker, and flannelmouth sucker population <br />demographics, life history, habitat requirements, and conservation needs. <br /> <br />. <br /> <br />Determine current population sizes of subject species and/or utilize auxiliary <br />catch and effort data to identify trends in relative abundance. <br />Identify subject species habitat requirements and current habitat conditions <br />through surveys and studies of hydrological, biological, and watershed features. <br />Determine if existing flow recommendations and regimes are adequate for all life <br />stages of the subject species. Develop appropriate flow recommendations for <br />areas where existing flow regimes are inadequate. <br />Where additional data is needed to determine appropriate management actions, <br />conduct appropriate, focused research and apply results. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />4.) Genetically and morphologically characterize populations of round tail chub, bluehead sucker, <br />and flannelmouth sucker. <br /> <br />. <br /> <br />Determine if known information is adequate to answer management questions <br />related to conservation genetics and assess need for additional genetic <br />characterization of subject species. <br />Apply new information to management strategies. <br />Review the literature available on hybridization and adequacy of existing data to <br />characterize the degrees of threats to conservation of the three species posed by <br />hybridization. <br />Develop genetic management plans for all three species that outline maintenance <br />of species at the population level and discuss application to reestablishment <br />efforts. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />5.) Increase roundtail chub, bluehead sucker, and flannelmouth sucker populations to accelerate <br />progress toward attaining population objectives for respective species. <br /> <br />. <br /> <br />Assure regulatory protection for three species is adequate within the signatory <br />states. <br /> <br />6) Enhance and maintain habitat for roundtail chub, bluehead sucker, and flannelmouth sucker. <br /> <br />. <br /> <br />Enhance and/or restore connectedness and opportunities for migration of the <br />subject species to disjunct populations where possible. <br />
