Nigeria

===Vegetation===
Nigeria is covered by three types of vegetation: forests (where there is significant tree cover), [[savannah]]s (insignificant tree cover, with grasses and flowers located between trees), and [[montane]] land (least common and mainly found in the mountains near the Cameroon border). Both the forest zone and the savannah zone are divided into three parts.<ref name="gai4">{{cite web |title=The Human and Physical Characteristics of Nigeria |url=http://www.uni.edu/gai/Nigeria/Background/Standard4.html |url-status=dead |archive-url=https://web.archive.org/web/20100328172528/http://www.uni.edu/gai/Nigeria/Background/Standard4.html |archive-date=2010-03-28 |access-date=2007-08-13 |work=Geographical Alliance of Iowa |publisher=[[University of Northern Iowa]]}}</ref>

Some of the forest zone's most southerly portion, especially around the Niger River and [[Cross River (Nigeria)|Cross River]] deltas, is [[Central African mangroves|mangrove swamp]]. North of this is fresh water swamp, containing different vegetation from the salt water mangrove swamps, and north of that is rain forest.<ref name="gai4" />

The savannah zone's three categories are divided into [[Guinean forest–savanna mosaic|Guinean forest-savanna mosaic]], made up of plains of tall grass which are interrupted by trees, the most common across the country; Sudan savannah, with short grasses and short trees; and [[Sahel]] savannah patches of grass and sand, found in the northeast.<ref name="gai4" />
