Brown Rat

Brown Rat (Rattus norvegicus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.

common tsessebe

<em>Damaliscus lunatus</em>, commonly known as the common tsessebe, is a large antelope in the family Bovidae, endemic to the grasslands and open savannas of sub-Saharan Africa. This species is among the fastest antelopes in Africa, capable of reaching speeds exceeding 80 kilometers per hour when fleeing predators. <em>Damaliscus lunatus</em> is typically found in moist, medium-height grasslands and floodplain grasslands, often near permanent water sources, across countries including Botswana, Zimbabwe, Zambia, Tanzania, and South Africa. The coat is a rich reddish-brown with a distinctive darker patch on the shoulders and upper hindquarters, and both sexes bear lyrate, heavily ridged horns. Tsessebe are highly selective grazers, favoring short to medium-height grasses, and they typically form herds that may number from a few individuals to several hundred during seasonal migrations. The species is currently assessed as Vulnerable by the IUCN, with populations declining due to habitat loss, hunting, and competition with livestock across much of its former range. Conservation efforts are focused on maintaining large protected grassland areas and managing livestock encroachment. Biological traits such as average lifespan, body weight, and body length are consistent with large bovid norms but precise population-wide figures remain poorly documented in the scientific literature.
