Cleft Bramble

The Cleft Bramble, Rubus laciniatus, known also as the Cutleaf or Evergreen Blackberry, is a vigorous, thorny shrub in the family Rosaceae native to central and southeastern Europe, from the Balkans through to southwestern Asia. It is widely naturalized in western North America, southern Australia, New Zealand, and other temperate regions where it was introduced as a garden plant or for erosion control. The distinctive deeply divided, laciniate leaves with finely cut leaflets distinguish it from other brambles. Like other Rubus species, it produces edible black fruits relished by birds and mammals, making it an important food plant for wildlife, but its vigorous growth and ability to root from stem tips make it an aggressive colonizer and a serious invasive species in many regions outside its native range. In the Pacific Northwest of the United States, Rubus laciniatus forms dense, impenetrable thickets that displace native vegetation and reduce biodiversity. Control is difficult given its extensive root system and the ability of fragments to regenerate. The species is listed as a noxious weed in several US states and Australian states. In its native European range, Cleft Bramble is not threatened and occurs in woodland edges, hedgerows, and scrubby habitats.

Clusterspike False Indigo

Amorpha crenulata, known as clusterspike false indigo or crenulate lead plant, is a critically endangered flowering shrub in the family Fabaceae with a highly restricted distribution confined to Miami-Dade County in southern Florida, USA. This species represents one of North America's rarest plants, with remaining populations numbering in the hundreds of individuals occurring in pine rockland habitat, an ecosystem itself ranked among the most imperiled in the United States. Pine rocklands are fire-dependent communities on exposed oolitic limestone, characterized by an open canopy of slash pine over diverse understory, and have been reduced to less than two percent of their historical extent by urban development in the Miami metropolitan area. Amorpha crenulata produces elongated spikes of small purple flowers typical of the genus and was historically more widespread across the Miami Rock Ridge before land development eliminated most habitat. Current populations exist primarily within Everglades National Park and a few private preserves. Its Critically Endangered status reflects the tiny remaining population, extreme habitat restriction, ongoing threats from urbanization, altered fire regimes, and sea-level rise that threatens low-elevation limestone habitats. Conservation efforts focus on habitat protection, controlled burning to maintain pine rockland structure, and ex situ seed banking.
