### Identification The Leadwood (*Combretum imberbe*) is the heavyweight champion of the African bushveld. Reaching up to 20 meters, its most distinctive field mark is the "crocodile-skin" bark—a pale, silvery-grey surface broken into neat, deep rectangular flakes. Unlike the larger, lime-green leaves of the Bushwillow cousins, the Leadwood’s leaves are tiny, grey-green, and leathery with wavy margins. In autumn, look for the classic *Combretum* four-winged fruits; they are small (15mm) and turn a distinct pale straw color when mature.
### Habitat & Range This species is a specialist of the semi-arid savannas of Southern Africa, stretching from the Limpopo Valley into the Okavango. It thrives in alluvial soils along seasonal riverbeds and drainage lines but is also a frequent resident on nutrient-rich termite mounds. It prefers elevations below 1,200 meters where frost is rare.
### Behaviour The Leadwood is the "Sentinel of the Savanna." It is incredibly slow-growing and long-lived, with some specimens dated at over 1,000 years old. An observer will often see "ghost trees"—skeletal, sun-bleached Leadwoods that have been dead for 80 years but remain standing because their wood is too dense for termites to penetrate. These provide essential high-altitude perches for vultures and raptors.
### Diet As a primary producer, the Leadwood "feeds" through deep-taproot hydration and photosynthesis. It is remarkably drought-resistant, drawing minerals from deep subterranean water tables. In the ecosystem "food web," it provides highly nutritious browse for elephants and giraffes, who target the protein-rich young leaves and twigs.
### Fascinating Fact The name "Leadwood" is literal: the wood is so incredibly dense (approximately 1,200kg/m³) that it actually sinks in water. If you drop a seasoned branch into a river, it won't float away; it will drop straight to the bottom like a stone.
