“…the public interests will be promoted by reserving these caves with as much land as necessary for the proper protection thereof,” William Howard Taft Presidential proclamation, 1909.

The importance of the land above the cave cannot be overlooked. Many of the processes occurring within the cave are greatly influenced by what is happening above ground. This is especially true via the exchange of air, water and food between the connected ecosystems.

The park is faced with the challenge of allowing the public enjoyment of the fragile ecosystem below and above ground without causing significant impacts to park resources, and hopefully giving the public a greater appreciation of this special place.

The National Park Service recognizes and appreciates the extent of public interest in the general management plan for Oregon Caves National Monument. Learn more about Park Planning.

Dragonflies and damselflies are ancient creatures that have lived on Earth far longer than mammals. They have sophisticated eyes, over twenty to thirty thousand per head. Dragonflies are fast fliers; the blue-eyed darner can fly 48 feet per second while chasing prey. Most can fly far, even able to survive crossing a sea or ocean, if they have to.
