Cole's Wattle

<em>Acacia colei</em>, commonly known as Cole's Wattle, is a tree or shrub in the family Fabaceae, subfamily Mimosoideae. The species is assessed as Least Concern on the IUCN Red List, indicating that it is not currently at elevated risk of extinction. It is documented in Kenya and Tanzania, where it is associated with tropical and subtropical grasslands and savannas within the Afrotropic realm. Like many acacias, <em>Acacia colei</em> is likely adapted to seasonally dry conditions, which are characteristic of the East African savanna ecosystems it inhabits. Members of the genus <em>Acacia</em> often play important ecological roles, providing shade, food, and habitat for a range of animals, and some fix atmospheric nitrogen through symbiotic associations with soil bacteria. Diet, population estimates, and biological measurements including length, weight, and lifespan are not specified in available data for this species. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects a relatively stable population in East African savanna landscapes.
