Romaneste - Joshua Tree National Park – acest parc national din sud-estul statului California este declarat un parc national din 1994 cand Congresul SUA a declarat cei 3,199.59 km2 ca pamant/desert protejat. Parcul este numit pentru padurile cu pomii bastinasi Joshua (Yucca brevifolia) care acopera cei peste 3 mii de km patrati. Aces pamant este putin mai mare decat statul din estul Americii- Rhode Island. Parcul include doua deserte- cel elevat, Deserul Mojave si cel plat, Desertul Colorado. Muntii mici San Bernardino fac parte din sut-westul Parcului.
Joshua Tree National Park is located in southeastern California. Declared a U.S. National Park in 1994 when the U.S. Congress passed the California Desert Protection Act (Public Law 103-433), it had previously been a U.S. National Monument since 1936. It is named for the Joshua tree (Yucca brevifolia) forests native to the park. It covers a land area of 790,636 acres (1,235.37 sq mi; 3,199.59 km2)– an area slightly larger than the state of Rhode Island. A large part of the park, some 429,690 acres (173,890 ha), is a designated wilderness area. Straddling the San Bernardino County/Riverside County border, the park includes parts of two deserts, each an ecosystem whose characteristics are determined primarily by elevation: the higher Mojave Desert and lower Colorado Desert. The Little San Bernardino Mountains run through the southwest edge of the park.

Romanian – Pomii Joshua ( Yucca brevifolia), pentru care este numit acest parc national, se gasesc in Desertul elevat Mojave. Pomii se afla si in paduri si singuri la distanta unii de altii.
The higher and slightly cooler Mojave Desert is the special habitat of Yucca brevifolia, the Joshua tree for which the park is named. It occurs in patterns from dense forests to distantly spaced specimens.
The Joshua tree, Yucca brevifolia, is a member of the Agave family. (Until recently, it was considered a giant member of the Lily family, but DNA studies led to the division of that formerly huge family into 40 distinct plant families.) Like the California fan palm, Washingtonia filifera, the Joshua tree is a monocot, in the subgroup of flowering plants that also includes grasses and orchids. Don’t confuse the Joshua tree with the Mojave yucca, Yucca schidigera. This close relative can be distinguished by its longer, wider leaves and fibrous threads curling along leaf margins. Both types of yuccas can be seen growing together in the park. The Joshua tree provides a good indicator that you are in the Mojave Desert, but you may also find it growing next to a saguaro cactus in the Sonoran Desert in western Arizona or mixed with pines in the San Bernardino Mountains.
