Habitat & Geographic Range

cocobolo

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common Silver Hairgrass

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Cameroon), Asia (Japan, South Korea), Europe (6 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (4 countries). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

cocobolo

Cocobolo (Dalbergia granadillo) is a medium to large tropical hardwood tree in the family Fabaceae, native to the dry and moist forests of Pacific Mexico and Central America, from Jalisco and Colima south through Guerrero, Oaxaca, and Chiapas into Guatemala and Honduras. The species is one of the most prized commercial rosewoods in the world, producing exceptionally dense, fine-grained heartwood in rich tones of red, orange, and brown with contrasting darker grain lines; this wood is used in high-end guitar fingerboards, knife handles, turning, and decorative woodwork. Unfortunately, this commercial value has driven intense illegal logging across much of its range, leading the IUCN to classify Dalbergia granadillo as Critically Endangered — the highest threat category short of extinction in the wild. The species is listed in CITES Appendix II, requiring documentation of sustainable harvest for international trade. Remaining populations are heavily fragmented in degraded and secondary forest, with mature trees of commercial size increasingly scarce. The slow growth rate of the species means that recovery of logged populations takes decades. Conservation initiatives include reforestation programmes, strengthening of enforcement against illegal logging, community-based forestry schemes, and research into propagation for plantation production as an alternative to wild harvest. Without effective action, Dalbergia granadillo faces continued population decline and potential extirpation from parts of its natural range.

Common Silver Hairgrass

<em>Aira caryophyllea</em>, commonly known as Common Silver Hairgrass, is a slender annual grass belonging to the family Poaceae within the order Poales. This delicate grass is currently classified as Endangered on the IUCN Red List, reflecting significant conservation concern despite its historically broad distribution. It is typically found across a remarkable diversity of biome types, including tropical and subtropical moist broadleaf forests, grasslands, savannas, and flooded habitats, demonstrating notable ecological versatility. Its geographic range spans multiple continents, with documented populations in Africa (Cameroon), Asia (Japan, South Korea), Europe, North America, Australia, and South America. As an annual grass, it completes its life cycle within a single growing season, reproducing via wind-dispersed seeds. The inflorescence typically bears silvery, shimmering spikelets that give the species its common name. Biological traits such as average lifespan, body dimensions, and dietary specifics follow typical patterns for annual grasses — drawing nutrients from soil through root absorption rather than consuming other organisms. The endangered status suggests populations may be declining due to habitat loss, land-use change, or invasive species pressure across parts of its range.
