It appears the number of Antrobia culveri in Tumbling Creek Cave has decreased substantially in the last 20 years but no quantitative data support this impression. A stratified sampling scheme was developed to monitor the population of this snail, which is endemic to Tumbling Creek Cave. Perma- nent markers divide an accessible stretch of Tumbling Creek Cave into seven variable-length sections of alternating “favorable” and “marginal” habitat. Favorable habitat is characterized as riffle habitat with gravel to large rocks and medium to fast stream flow. Marginal habitat is characterized as large pool (deeper than 0.6 meter) and minimal flow, or riffle habitat with a solid rock bottom. A PVC frame (0.09 meter square) is used as a sampling square. Rocks within a square are examined and the number of snails observed is recorded. The number of plots in each section constitutes approximately 3% or 1% of substrate area (for favorable and marginal habitats, respectively) within that section. Comparisons (between habitats, seasons, or years) can be made. 1999 National Cave and Karst Management Symposium 7 Planning for the Impact of Convention Caving Ann Bosted Cave Research Foundation Menlo Park, California Abstract Annual NSS National Conventions are attracting larger attendance and it is estimated that 50% to 75% of cavers attending expect to go underground at least once during the five-day event. Often convention sites are chosen for the facilities with little attention being paid to the capacity of the caves in the area. Convention organizers may put pressure on cave managers to relax visitation limits in order to accommodate the increased demand. Those that do so may later regret their hospitable gestures when the caves are degraded. Should cave managers and cavers be allowed or encouraged to voice their concerns about the potential impact of a proposed convention on caves in the area? What would be the best way to evaluate the impact of a proposed convention? What are the pros and cons of limiting convention caving? What is the responsibility of the NSS in making these decisions? These questions will be discussed in relation to past and future planned conventions. 8 1999 National Cave and Karst Management Symposium Here Today, Gone Tomorrow? Initiating Steps for Preserving West Virginia’s Cave and Karst Terrain Jeff Bray West Virginia Cave Conservancy 820 Meerkat Lane Christiansburg, VA 24073 (540) 382-1319 [email protected] Abstract Nationwide, caves and karst terrains face serious threats from a multitude of social and economic forces such as construction activities. At the same time many have felt a strong need for greater education and outreach efforts regarding karst regions for protecting these rare and fragile environments from being obliterated. In a manner similar to other cave and karst bearing regions, West Virginia continues to recognize challenges and evolve feasible solutions for protecting its caves and karst resources. Moreover, any such forward-looking strategies must involve a proactive, rather than a reactive stance in planning. However, until recently, there was lack of a formalized, concerted, viable group dedicated to the mission of preserving the state’s karst regions. This presentation offers an overview of the West Virginia Cave Conservancy, a federally-recognized, 501(c)(3) status organization pres- ently working with communities in West Virginia to pursue its preservation and management missions. The Conservancy is doing this by working to purchase or lease caves (such as Rapps Cave, a significant archaeological site that was recently leased to the West Virginia Cave Conservancy). The Conservancy also works with cave owners to create management plans that will allow access to such areas while protecting the landowners. This presentation outlines the stages involved in the evolution of the West Virginia Cave Conservancy as a recent organization and emphasizes specific cave and karst-related goals and objectives that are central to its mission.
