The BLM's Bishop Field Office is increasing its efforts to educate climbers and campers on how to enjoy natural resources without damaging them, especially as the number of visitors grows. Over the past decade, the Bishop Field Office has experienced an increase in climbing and car camping activity in the Volcanic Tableland north of Bishop. Damage to cultural and natural resources has also increased, with some visitors leaving trash or human waste, building improper fires, camping in archeological sites or on sensitive vegetation and creating new roads, trails and parking areas.
