Habitat & Geographic Range

Coastal Iris

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Green Sea Turtle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, Brazil, Costa Rica, Indonesia, and Mexico. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Coastal Iris

Iris atropurpurea, the coastal iris or Sharon iris, is a bulbous geophyte in the family Iridaceae critically endangered and endemic to the coastal plain of central Israel, one of the most range-restricted irises in the world. The species is confined to a narrow strip of the Sharon plain sandy coastal habitat, a Mediterranean coastal sandstone and sandy soil ecosystem that has been almost entirely eliminated by the sprawling Tel Aviv metropolitan area and its associated agricultural conversion. Iris atropurpurea produces striking deep purple to blackish-purple flowers with intricate veining and yellow signals in late winter and early spring, blooming briefly before entering summer dormancy as a bulb in the dry Mediterranean season. Fewer than twenty natural populations of this species are thought to survive, all within a highly fragmented and disturbed coastal landscape under permanent threat from urban expansion, recreational pressure, invasive alien plants, and changes in grazing regimes that alter the open sandy habitat structure the iris requires. It is classified as Critically Endangered by the IUCN. Conservation efforts include habitat protection in a few coastal reserves, translocation programs, and cultivation in Israeli botanical gardens to secure genetic material against the extinction of remaining wild populations.
