Snake Creek Road and Campsites Closed
The Snake Creek Road will be closed from the park boundary into the park to begin work on campsites, trails and restroom improvements. Work will continue until snow closes the project. Work will resume in Spring 2015.
The Great Basin is a desert, averaging less than 10 inches of rain a year. It is a cold desert, and because of its high elevation, it receives most of its moisture in winter snows. Despite these dry conditions there are over 800 different plant species in the park and South Snake Range, of these 13 are considered sensitive species. The way many of these plant species are able to survive in this environment is through specialized adaptations or by living in the cooler, wetter mountain ranges.
Dealing With Little Water
Other adaptations help keep plants from losing their water. The Sagebrush, a very common resident of the Great Basin, is well adapted to the area. The Big Sagebrush root system can extend as much as 90 feet in circumference. This adaptation allows the plant to catch as much water as possible when the rains do come. The hairy leaves of sagebrush work as a windbreak to slow down evaporation from leaves. Other methods of water loss prevention are waxy leaves and succulence. The waxy coat acts as a barrier to evaporation by the wind. Succulence allows plants to hold water for the drier times. Greenleaf manzanita is an example of a plant with a waxy coat and prickly pear cactus is a succulent.
Plants exchange gases, including water, through their leaves by a process called transpiration. Plants in this area can not afford to lose much water through evapotranspiration (the process by which plants release oxygen and sometimes water) and have developed modified leaves. Mormon tea or joint fir possesses modified leaves. The leaves are very small and are not the primary area for photosynthesis. The chlorophyll filled stems carry out the primary photosynthesis.

Did You Know?
Many of Great Basin National Park's bristlecone pines were growing at the time the Egyptians were building the pyramids. Not only are the trees themselves old, but the needles alone can be 25-40 yrs old!
