This colorful map, titled Natural Vegetation, is part of Philips' Comparative Wall Atlas of North America and provides an ecological overview of the continent’s natural vegetation zones. The map is color-coded to indicate various types of vegetation, from the ice deserts of the Arctic to tropical forests in Central America and the Caribbean. The use of distinct colors and patterns helps to differentiate the primary ecological regions, revealing a broad diversity of habitats across North America.
Vegetation types are detailed in the reference legend, which includes categories such as Coniferous Forest, Broad-leaved Forest, Temperate Grasslands, Desert, and Tropical Forests. Each region is shaded accordingly, with darker greens representing dense forests, yellows indicating grasslands, and browns and oranges marking arid zones like deserts and semi-deserts. The map captures both the major environmental zones of the United States and Canada, as well as Mexico, Central America, and parts of the Caribbean.
A small inset shows the comparative size of the British Isles.
Edited by J. F. Unstead and E. G. R. Taylor, the map offers a comprehensive visualization of North America’s varied ecological landscapes, serving as an educational tool for understanding the natural flora of the continent and the geographic factors influencing biodiversity.
