General Wildlife

• Approximately 355 Bird, 89 mammal, 47 reptile, 9 amphibian, and thousands of aquatic and terrestrial invertebrate species can be found in GCNP and GCNRA's Glen Canyon reach. (NPS CFMP-EA_pg 19)

General Plant Species

• Approximately 129 vegetation communities, Over 850 species have been reported from GCNRA, and over 1,750 vascular plant species from GCNP (NPS CFMP-EA_pg 19)

Work in progress

1. Riparian communities are dominated by species such as coyote and seep willows, arrowweed, western honey mesquite, catclaw acacia, and exotic tamarisk with many other species present.
2. Desert Scrub communities are dominated by species such as creosote, white bursage, brittle bush, ocotillo, four-wing saltbush, big sagebrush, ephedra, dropseed, brome grasses, and many other species.
3. Approximately 11% of flora in GCNP and GC reach is exotic.
