The National Park Service has announced that they will be conducting nature walks through the various parks and monuments for which they are responsible--explaining the plants and animal life that can be found in each of these areas. 

The guided walks require advance registration, and one of them is conducted at night at Saguaro National Park east of Tucson.  For the night walk, visitors are urged to dress warmly and bring flashlights and water.
