This site was constructed through a joint effort of Bat Conservation International and the Bureau of Land Management as a guide for determining the most appropriate closure type specific mine openings. 

  • This tool is designed for public land managers, mining companies, consultants and contractors, and anyone else actively participating in abandoned mine closure projects.
  • When you begin using the Decision Matrix Tool, you will need adequate data on each mine opening that is being considered. These include geographic location, wildlife use, opening size and orientation, cultural resources that require protection and rock conditions at the opening.
  • As a general rule, we discourage managing individual mines as crises develop. This "whack-a-mole" approach is often more expensive and less effective for conservation than a landscape-level approach that considers all resident bat populations and all potential mine roosts in the area.
  • We look forward to your feedback!
