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.

Common Least Skipper

The Common Least Skipper (<em>Ancyloxypha numitor</em>) is a small butterfly in the family Hesperiidae, classified as Least Concern on the IUCN Red List. It is native to Canada and the United States, where it typically inhabits virtually all terrestrial and freshwater habitats within its range, showing a particular affinity for moist, grassy areas near water. The species is among the smallest skippers in North America, characterized by orange and brown wing coloration and a rapid, low-flying flight pattern close to vegetation. Adults typically nectar on small flowers while larvae feed on grasses, particularly those in wet meadows, marshes, stream margins, and disturbed grassy areas. The Common Least Skipper is frequently observed in wetland margins, wet prairies, and roadsides with rank grass growth. Its wide distribution across North America and habitat generalism across moist grassland and wetland types support its stable population and Least Concern conservation status. Biological traits of this species remain poorly documented in the scientific literature.
