Ecology and Natural Resources
Some resources are oil, natural gas, phosphates, and sulfur.
The Rub'al-Khali has very limited floristic diversity. There are only 37 species, 20 recorded in the main body of the sands and 17 around the outer margins. Among these 37 species, only one or two are endemic. Vegetation is very diffuse but fairly evenly distributed, with some interruptions of near sterile dunes.
Some typical plants are
- Calligonum crinitum on dune slopes
- Cornulaca arabica (saltbush)
- Cyperus conglomeratus.
Other widespread species are
- Dipterygium glaucum
- Limeum arabicum
- Zygophyllum mandavillei (Mandaville 1986).
Very little trees may be found except at the outer margin (typically Acacia ehrenbergiana and Prosopis cineraria).
Other species are a woody perennial Calligonum comosum and annual herbs such as Danthonia forskallii

Famous quotes containing the words ecology, natural and/or resources:
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
“Doubtless, we are as slow to conceive of Paradise as of Heaven, of a perfect natural as of a perfect spiritual world. We see how past ages have loitered and erred. “Is perhaps our generation free from irrationality and error? Have we perhaps reached now the summit of human wisdom, and need no more to look out for mental or physical improvement?” Undoubtedly, we are never so visionary as to be prepared for what the next hour may bring forth.”
—Henry David Thoreau (1817–1862)
“I am willing to pledge myself that if the time should ever come that the voluntary agencies of the country together with the local and state governments are unable to find resources with which to prevent hunger and suffering ... I will ask the aid of every resource of the Federal Government.... I have the faith in the American people that such a day will not come.”
—Herbert Hoover (1874–1964)
