Sahuaro High School Alumni
The saguaro ( , ; ''Carnegiea gigantea'') is a tree-like cactus species in the monotypic genus ''Carnegiea'' that can grow to be over tall. It is native to the Sonoran Desert in Arizona, the Mexican state of Sonora, and the Whipple Mountains and Imperial County, California, Imperial County areas of California. Saguaro typically grow at elevations ranging from sea level to 4,500', although they may be found at up to 5,000'. The saguaro blossom is the list of state flowers, state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1933, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat. Saguaros have a relatively long lifespan, often exceeding 150 years. They may grow their first side arm around 75–100 years of age, but some never grow any arms. Arms are developed to increase the plant's reproductive capacity, as more apical meristem, apices lead to more flowers and fruit. A sagu ...

Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull. The main forms of precipitation include drizzle, rain, rain and snow mixed ("sleet" in Commonwealth usage), snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation; their water vapor does not condense sufficiently to precipitate, so fog and mist do not fall. (Such a non-precipitating combination is a colloid.) Two processes, possibly acting together, can lead to air becoming saturated with water vapor: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called shower (p ...

Rocky Mountain Research Station
The Rocky Mountain Research Station (RMRS) is one of five regional units that make up the United States Forest Service Research and Development organization — the most extensive natural resources research organization in the world. The station headquarters are located in Fort Collins, Colorado. Research is structured within eight science program areas. The Station employs over 400 permanent full-time employees, including roughly 100 research scientists. The station is dedicated to advancing the understanding and sustainable management of the nation's forests and grasslands through cutting-edge scientific research. With a focus on improving ecosystem health, resilience, and the utilization of natural resources, the RMRS plays a crucial role in addressing the challenges posed by climate change, natural disturbances, and human impact on the environment. One of the key areas of research at the RMRS is the study of wildfire and resilient landscapes. Through the development of new ...

Branch
A branch, also called a ramus in botany, is a stem that grows off from another stem, or when structures like veins in leaves are divided into smaller veins.

They are also related to the Sobaipuri, whose descendants reside on the San Xavier Indian Reservation or Wa꞉k (together with the Tohono O'odham), and in the Salt River Indian Community. Together with the related Tohono O'odham ("Desert People") and the Hia C-ed O'odham ("Sand Dune People"), the Akimel O'odham form the Upper O'odham. N ...

Keystone Species
A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measur ...
