Habitat & Geographic Range

chimpanzee

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 5 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Cameroon, Congo (DRC), Guinea, Tanzania, and Uganda. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Coco-grass

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

chimpanzee

Humanity's closest living relative, sharing approximately 98.7% of DNA, chimpanzees inhabit tropical forests and savanna woodlands across central and West Africa. Highly intelligent, social primates that use and make tools, display cultural traditions, and communicate with rich vocalizations including the distinctive pant-hoot. Endangered, with populations declining due to deforestation, bushmeat hunting, and disease transmission from humans.

Coco-grass

Coco grass (Cyperus rubicundus) is a perennial sedge in the family Cyperaceae, native to tropical and subtropical regions of Africa, South Asia, and Southeast Asia, but now naturalised as a weed across much of the pantropical zone, including the Americas, Australia, and the Pacific. The species forms dense tufts of grass-like foliage growing to 20–60 centimetres from creeping rhizomes and small, dark tubers in the soil. Flower heads are reddish-brown to purplish, borne on triangular stems in compact compound umbels. Like the closely related purple nutsedge (Cyperus rotundus) — one of the world's most problematic agricultural weeds — C. rubicundus spreads aggressively through both seed and vegetative means via its tuber-bearing rhizomes, enabling rapid colonisation of disturbed ground, irrigated fields, gardens, and roadsides in warm climates. The tubers serve as propagules that survive soil disturbance and are difficult to eradicate mechanically, making infestations persistent. Despite its weed status, the species has documented traditional uses: the dried rhizomes have been used medicinally in parts of Asia for gastrointestinal conditions and as an aromatic ingredient in perfumery and cosmetics. Cyperus rubicundus is classified as Least Concern by the IUCN, reflecting its wide distribution and robust, expanding populations in anthropogenic habitats globally. Research into biological control has targeted related invasive Cyperus species in some regions.
