The province is highly urbanised & industrialised. At Blesbokspruit (near Springs) there are wetlands of international importance. Gauteng is home to the largest Wonderboom fig tree (Ficus salicifolia); which is found in Wonderboom Poort, Tshwane metropolitan area. In earlier years, the tree was used as an ox wagon outspan area, and there is a legend that a Matabele chief was buried under the tree.
The largest monkey thorn tree (Acacia galpinii) is found in Rust de Winter.
Gauteng's agricultural sector is geared to provide the cities and towns of the province with daily fresh produce, including dairy products, vegetables, fruit, meat, eggs and flowers. A large part of the province falls within the "maize triangle". The districts of Bronkhorstpruit, Cullinan and Heidelberg are important agricultural land, where ground-nuts, sunflowers, cotton and sorghum are produced.
