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.

Common Tiger Beetle

<em>Cicindela campestris</em>, the common green tiger beetle, is a predatory beetle in the family Cicindelidae, recorded from Belgium, Denmark, Norway, and Sweden. It is classified as Near Threatened on the IUCN Red List, reflecting population declines linked to habitat loss, particularly the loss of open sandy heathlands, coastal dunes, and dry grasslands across its European range. This beetle is one of the fastest-running terrestrial insects and is an active, visual predator that pursues invertebrate prey with speed and agility. It is characterized by vivid metallic green elytra spotted with cream or white, providing camouflage against sandy substrates. Adults are typically 12–15 millimeters long and are found on bare, sun-exposed sandy ground. Larvae are ambush predators living in vertical burrows in sandy soil, capturing passing insects. The species requires warm, sparsely vegetated sandy habitats that are increasingly rare due to land-use change, scrub encroachment, and development. Conservation of heathland and dune habitats is critical for maintaining viable populations of this Near Threatened species.
