Vegetation is an assemblage of plant species and the ground cover they provide. [2] It is a general term, without specific reference to particular taxa , life forms, structure, spatial extent, or any other specific botanical or geographic characteristics.
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.
It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. [2] There are latitudinal gradients in species diversity for both marine and terrestrial taxa. [3]

African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while the baobab stores water in its trunk for the dry season. Many of these savannas are in Africa.
When not limited by other factors, increasing CO 2 concentration in the air increases plant growth, similarly as water use efficiency, which is very important in drier regions. However, the advantages of elevated CO 2 are limited by factors including water availability and available nutrients , particularly nitrogen.
A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.
