All-important in cave restoration is the notion of leaving things better than we found them-while avoiding new harm to biota, habitat, or other cave resources. When considering a project-assess, plan, and avoid creating new problems. Thoroughly evaluate the restoration tasks. Carefully design the workload and crew assignments. Conscientiously avoid causing new restoration dilemmas in the cave passages. When the project is complete, clean up any leftover mess. These are simple, universal precepts.

In many cave systems, no harm is literally impossible if humans enter. More realistically, we strive to minimize our harm-and we should recognize that whatever we do in a cave may damage the resources in some way we have not yet anticipated. In caves, causing no new harm may sometimes mean doing nothing to remediate horrible impacts. Other times, we decide to attempt restoration with sincere and well-considered efforts toward minimizing new damage to cave values. With our inadequacies acknowledged, maybe we should choose an axiom like minimize harm, but instead we use the admonition do no harm. It is a strong statement-it reminds us to reach for the depths of ideal caving ethics and informed restoration decisions.
