Cinerous Groundling

The cinerous groundling (Bryotropha terrella) is a small moth in the family Gelechiidae, distributed across Europe including Britain, Scandinavia, and much of continental Europe. It inhabits dry, open habitats such as heathland, sand dunes, chalk grassland, and dry grassland margins, where its larvae feed on mosses and low-growing plants close to the soil. The adult moth has pale straw-colored to gray-brown forewings with indistinct markings, providing camouflage in its dry, open habitat. Like many gelechiid moths, Bryotropha terrella is a small, inconspicuous species that is frequently under-recorded due to the challenges of identifying micro-moths. The species is classified as Least Concern, with populations found across a wide range of European countries with suitable dry, open habitat. Its larval association with mosses and low vegetation makes it dependent on short, open sward conditions—habitats that have declined in parts of Europe due to agricultural intensification, scrub encroachment following the abandonment of traditional grazing, and afforestation. Moth surveys using light traps and careful examination of micro-lepidoptera have expanded knowledge of this and related gelechiid species' distributions. Conservation of dry heathland and chalk grassland habitats benefits a wide range of invertebrates including this species.

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.
