Page 52 Progress toward achieving the overall goal will be used to evaluate effectiveness -have we established or maintained the designated number of populations in each management unit? If one population is lost, the Team can choose to re-establish this population using a nearest neighbor ~ population, any genetically appropriate population, or a highly robust and healthy population either in the same location or in a different stream within the unit or state. We are currently considering the need for a hatchery or grow-out facilities only for bluehead sucker in the Bonneville Basin; however, three species cooperators may eventually decide these options are a necessity for all three species. In any event, hatchery fish will also be adequate to restore a . population as long as appropriate hatchery management plans have been developed. We will consider our efforts successful if the designated number of populations are reached and persist through the life of the Agreement. In addition to the number of populations in a management unit we must also identify the adequate population size within each unit to help determine if we are successful. For each ~ species, the Team will attempt to determine the number of individuals required per population to maintain the population in perpetuity. Because we have limited life history and historical information on these species, we must leave this criterion for later refinement. We will use historical and newly collected data to further refine population criteria. These values will be assigned by year five of the Agreement (2009). ~ If we find that it is too difficult or expensive to effectively evaluate the number of individuals per population statewide, we will instead use population trends or relative abundance over the course of the Agreement to determine whether we are successful in meeting this criteria. Because it will likely be difficult to maintain up-to-date information on all streams statewide, we will not require ~ recent information on all streams at the end of the Agreement. Instead we will evaluate the observed situation from 2009 - 2014 (the last five years of the Agreement), compile that with the information obtained through baseline surveys in 2003 through 2009, and use all of this information to make a determination.
