19 State Parks Could Close for Financial Reasons
Highlights of the 2010 River Management Society and National Association of Recreation Resource Planners Symposium The River Management Society joined with the National Association of Recreation Resource Planners (NARRP) to host their biennial symposium on river management. Recognizing resource protection as a core value, the symposium explored how scientists, planners, and managers are maintaining or restoring ecosystem sustainability while providing opportunities for high quality recreation experiences on rivers, lakes, and reservoirs. Participants at the symposium interacted with regional and national leaders in river conservation and recreation management through a diverse program. The symposium theme, “Bridging Conservation and Recreation” recognizes that resource professionals too often become narrowly focused in their specialties, and that effective long- term management usually requires broader cross-disciplinary solutions. The symposium provided opportunities for professionals to network and integrate their knowledge from many fields. Attendees left with renewed creativity and passion for natural resource management in watersheds. Feedback from Symposium Attendees Mary Donze, Missouri Division of State Parks “While all of the educational sessions I attended were wonderful, it was the networking that took place at the breaks and dinners that was the most valuable. It is amazing how many agencies are facing the same issues. The camaraderie that develops at the annual conference is truly inspiring. It is nice to take that home; knowing you have lots of fellow professionals to contact, when you need advice on an issue or problem. Meeting the student scholarship recipients was also a highlight of the conference. It is so gratifying to see such amazing young professionals entering the field."

LOCAL SPOTLIGHT Edwards Aquifer, San Antonio, Texas, United States—Protecting Groundwater
LOCAL SPOTLIGHT Edwards Aquifer, San Antonio, Texas, United States—Protecting groundwater Photo: © Blake Gordon Photo: © Blake Gordon North America Left. Officials release a benign "tracer dye" into Edwards Aquifer drainage systems to chart flows and track the underground water pathways. Right. Hydrogeologist descends into a sinkhole to check on the Edwards Aquifer. The challenge As one of the largest, most prolific artesian aquifers in the world, the Edwards Aquifer serves as the primary source of drinking water for nearly 2 million central Texans, including every resident of San Antonio—the second largest city in Texas—and much of the surrounding Hill Country. Its waters feed springs, rivers and lakes and sustain diverse plant and animal life, including rare and endangered species. The aquifer supports agricultural, industrial and recreational activities that not only sustain the Texas economy, but also contribute immeasurably to the culture and heritage of the Lone Star State. AUSTIN The aquifer stretches beneath 12 Texas counties, and the land above it includes several important hydrological areas. Two areas in particular— the drainage area and the recharge zone—replenish the aquifer by “catching” rainwater, which then seeps through fissures, cracks and sinkholes into the porous limestone that dominates the region. While this natural filtration system helps refill the aquifer with high-quality water, the growing city of San Antonio is expanding into territories of the very sensitive recharge zone, increasing the risk of contamination. In Edwards Aquifer SAN ANTONIO addition to a rising population, the state’s water supplies have been impacted by multi-year droughts. By 2060, Texas is projected to be home to approximately 50 million people while the annual available water resources are estimated to decrease by nearly 10 percent. -

Habitat and Phenology of the Endangered Riffle Eetle, Heterelmis
Arch. Hydrobiol. 156 3 361-383 Stuttgart, February 2003 Habitat and phenology of the endangered riffle beetle Heterelmis comalensis and a coexisting species, Microcylloepus pusillus, (Coleoptera: Elmidae) at Comal Springs, Texas, USA David E. Bowles1 *, Cheryl B. Barr2 and Ruth Stanford3 Texas Parks and Wildlife Department, University of California, Berkeley, and United States Fish and Wildlife Service With 5 figures and 4 tables Ab tract: Habitat characteristics and seasonal distribution of the riffle beetles Herere/ mis comalensis and Microcylloepu pusillus were studied at Comal Springs, Texas, during 1993-1994, to aid in developing sound reconunendations for sustaining their natural popu1atioas. Comal Springs consists of four major spring cutlers and spring runs. The four spring-runs are dissimilar in size, appearance, canopy and riparian cover, substrate composition, and aquatic macrophyte composition. Habitat conditions associated with the respective popuJatioos of riffle beetles, including physical-chemi cal measurements, water depth, and currenc velocity, were relatively unifom1 and var ied lHUe among sampling dates and spring-runs. However, the locations of the beetles in the respective spri ng-runs were not well correlated to current velocity, water depth, or distance from primary spring orifices. Factors such as substrate size and availability and competition are proposed as possibly influencing lheir respective distributions. Maintaining high-quality spring-flows and protection of Lhe physical habitat of Here· re/mis comalensis presently are the only means by which to ensure the survival of this endemic species. Key words: Conservation, habitat conditions, substrate availability, competition. 1 Authors' addresses: Texas Parks and Wildlife Department, 4200 Smith School Road, Austin, Texas 78744, USA. -

(ESA), to authorize the incidental take of two endangered species, the golden-cheeked warbler (Dendroica chrysoparia) and the black-capped vireo (Vireo atricapilla), referred to collectively as the “Covered Species.” In support of the Permit application, the County has prepared a regional habitat conservation plan (Proposed RHCP), covering a 30-year period from 2010 to 2040. The Permit Area for the Proposed RHCP and the area of potential effect for this Environmental Impact Statement (EIS) is Comal County in central Texas. The requested Permit would authorize the following incidental take and mitigation for the golden-cheeked warbler: Take: As conservation credits are created through habitat preservation, authorize up to 5,238 acres (2,120 hectares) of golden-cheeked warbler habitat to be impacted over the 30-year life of the Proposed RHCP. -
