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.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
