Sahuaro
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. The saguaro blossom is the list of state flowers, state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1994, 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 saguaro can absorb and store considerable amounts of rainwater, visibly expanding in the process, while slowly using the ...

National Register Of Champion Trees
The National Register of Champion Trees is a list of the largest tree specimens found in the United States as reported to American Forests by the public. A tree on this list is called a National Champion Tree. The National Register of Champion Trees has been maintained since 1940 by American Forests. To be eligible, a species must be recognized as native or naturalized in the United States. American Forests uses the following formula to calculate a point score for each tree so that they may be compared to others: :Trunk Circumference (in inches) + Height (in feet) + 1/4 Average Crown Spread (in feet) = Total Points Americanforests.org The National Register of Champion Trees is updated yearly and is available to view online. In addition to the national list, states, counties, and cities maintain their own list of local Champion Trees.

Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, 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 but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: 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 showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

US Forest Service
The United States Forest Service (USFS) is an agency of the U.S. Department of Agriculture that administers the nation's 154 national forests and 20 national grasslands. The Forest Service manages of land. Major divisions of the agency include the Chief's Office, National Forest System, State and Private Forestry, Business Operations, and Research and Development. The agency manages about 25% of federal lands and is the only major national land management agency not part of the U.S. Department of the Interior, which manages the National Park Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management. History The concept of national forests was born from Theodore Roosevelt's conservation group, Boone and Crockett Club, due to concerns regarding Yellowstone National Park beginning as early as 1875. In 1876, Congress formed the office of Special Agent in the Department of Agriculture to assess the quality and conditions of forests in the United States. ...

Branch
A branch, sometimes called a ramus in botany, is a woody structural member connected to the central trunk (botany), trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term ''twig'' usually refers to a wikt:terminus, terminus, while ''bough'' refers only to branches coming directly from the trunk. Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly vertical and horizontal, horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci, their cross section (geometry), cross-sectional areas closely follow the da Vinci branching rule. Terminology Because of the enormous quantity of branches in the world, there are numerous names in Engl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pima People
The Pima (or Akimel O'odham, also spelled Akimel Oʼotham, "River People," formerly known as ''Pima'') are a group of Native Americans living in an area consisting of what is now central and southern Arizona, as well as northwestern Mexico in the states of Sonora and Chihuahua. The majority population of the two current bands of the Akimel O'odham in the United States are based in two reservations: the Keli Akimel Oʼodham on the Gila River Indian Community (GRIC) and the On'k Akimel O'odham on the Salt River Pima-Maricopa Indian Community (SRPMIC). The Akimel O'odham are closely related to the Ak-Chin O'odham, now forming the Ak-Chin Indian Community. 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 Upp ...

Tohono Oʼodham
The Tohono Oʼodham (; Oʼodham: ) are a Native American people of the Sonoran Desert, residing primarily in the U.S. state of Arizona and the northern Mexican state of Sonora. The federally recognized tribe is known in the United States as the Tohono Oʼodham Nation. The Tohono Oʼodham Nation, or Tohono Oʼodham Indian Reservation, is a major reservation located in southern Arizona, where it encompasses portions of three counties: Pima, Pinal, and Maricopa in the United States. It also extends into the Mexican state of Sonora. Name The Tohono Oʼodham tribal government and most of the people have rejected the historical name Papago used by European colonizers. They call themselves ''Tohono Oʼodham'', meaning "desert people". The Pima, a competing tribe in this territory, referred to them as ''Ba꞉bawĭkoʼa'', meaning "eating tepary beans". The Spanish colonizers learned that name from the Pima and transliterated it as ''Pápago'', in their pronunciation. European-Ame ...
