Species Profile

**Algarrobilla (Senna sophera)** Algarrobilla is a leguminous shrub or small tree belonging to the Fabaceae family, characterized by compound leaves with paired leaflets and bright yellow flowers arranged in terminal clusters. The species produces distinctive flat seed pods and can reach heights of 2-4 meters. As a nitrogen-fixing plant, it plays an important ecological role in soil enrichment and serves as a food source for various pollinators and seed-dispersing animals. This species is native to tropical and subtropical regions of the Americas, with historical distributions spanning parts of Central and South America. Algarrobilla typically inhabits dry forests, scrublands, and disturbed areas, demonstrating adaptation to semi-arid conditions and poor soils. The species' Critically Endangered status reflects severe population declines, though specific threat assessments remain incomplete. Habitat destruction through agricultural expansion and urban development likely represents the primary pressure on remaining populations. Deforestation for cattle ranching and crop cultivation has fragmented the dry forest ecosystems where Algarrobilla naturally occurs. Climate change may pose additional stress through altered precipitation patterns in already water-limited environments. Current conservation efforts for Algarrobilla appear limited, with insufficient documentation of active protection programs or habitat restoration initiatives. The lack of comprehensive threat assessment and population monitoring represents a significant knowledge gap hindering effective conservation planning. The outlook for Algarrobilla remains uncertain due to inadequate population data and unknown trends. Without immediate research to establish baseline population numbers and implement targeted conservation measures, this species faces continued risk of further decline or potential extinction.

Senna sophera faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its native range. The species is further threatened by overexploitation for medicinal purposes and invasive species competition in its remaining fragmented habitats.
