Subsequently, <br />in 1992, the Research Program was placed under the auspices of the San Juan River Basin <br />Recovery Implementation Program (SJRIP). The Research Program involved a variety of <br />activities designed to characterize the current status of the resident fish community (particularly <br />the federally protected Colorado pikeminnow, Ptychocheilus lucius, and razorback sucker, <br />Xyrauchen texanus); to identify and quantify those factors (biotic and abiotic) that may be limiting <br />protected fish species; and to identifY management and conservation activities that may eontribute <br />to the recovery of protected species. Much of the research begun under the Seven-Year Research <br />Program has been completed and a variety of management and conservation activities initiated. <br /> <br />SAN JUAN RIVER BASIN <br />RECOVERY IMPLEMENTATION PROGRAM <br />MONITORING PROTOCOLS <br /> <br />The San Juan River Basin Recovery Implementation Program Long Range <br />Implementation Plan was designed to be an "adaptive management" effort (Section 4.7 of Long <br />Range Plan) wherein research and particularly management/conservation activities are modified to <br />reflect new information, To aid in the practiee of adaptive management, the Long Range Plan <br />also direeted that "A long-term monitoring program be developed and implemented...". In <br />Section 5.7,1, development and implementation of "a long-term standardized monitoring program <br />to identifY changes in the endangered and other native fish species p~pulations, status, <br />distributions, and habitat conditions" is identified as a "Milestone." <br /> <br />Prior to and during the Seven-Year Research effort, several factors were identified that <br />might limit or adversely affect the status of native fishes, in particular Colorado pikeminnow and <br />razorback sucker, in the San Juan River. Briefly, these are; <br /> <br />Low population size ofCillilrad. pikeminnow and razorback sucker, <br />availability of suitable/needed habitats for completion .f life history stages, <br />absence of a "natural" flow regime (high spring runoff, low summer and winter base <br />flows, with storm generated flow spikes), <br />. water quality (temperature and contaminants), <br />nonnative fishes (predat.rs and cempetitors), and <br />disease. <br /> <br />The SJRIP has, as one of its two primary goals, the conservation of populations of <br />Colorado pikeminnow and razorback sucker in the San Juan River basin. With these program <br />goals in mind, the following Monitoring Plan goals have been developed: <br /> <br />1. Track the status and trends of the endangered and other fish populations in the San <br />Juan River. <br />2. Track changes in abiotic parameters, including water quality, channel morphology, <br />and habitat, important to the fish community. <br /> <br />DraO. Long Term Monitoring Plan.
