According to the World Wide Fund for Nature, the territory of the Czech Republic can be subdivided into four terrestrial ecoregions:
Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
The Western European broadleaf forests is an ecoregion in Western Europe, and parts of the Alps. It comprises temperate broadleaf and mixed forests, that cover large areas of France, Germany and the Czech Republic and more moderately sized parts of Poland, Austria, Switzerland and Belgium. Luxembourg is also part of this ecoregion.
The European-Mediterranean montane mixed forests is a composite ecoregion of southern Europe and North Africa, designated by the World Wildlife Fund as one of their Global 200 ecoregions, a list of priority ecoregions for conservation.
The Caucasus-Anatolian-Hyrcanian temperate forests is a composite ecoregion of southern Europe and West Asia, designated by the World Wildlife Fund as one of their Global 200 ecoregions, a list of priority ecoregions for conservation.
The Eastern Mediterranean conifer-sclerophyllous-broadleaf forests, also known as the Eastern Mediterranean conifer-broadleaf forests, is an ecoregion in the eastern Mediterranean Basin. It covers portions of Turkey, Syria, Iraq, Lebanon, Israel, Palestinian territories, Jordan, and Saudi Arabia.
The Sarmatic mixed forests constitute an ecoregion within the temperate broadleaf and mixed forests biome, according to the World Wide Fund for Nature classification. The term comes from the word "Sarmatia".
The Balkan mixed forests are a terrestrial ecoregion of southeastern Europe according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm.
The Illyrian deciduous forests is a terrestrial ecoregion in southern Europe, which extends along the eastern coast of the Adriatic Sea. It belongs to the Mediterranean forests, woodlands, and scrub biome, and is in the Palearctic realm.
The Dinaric Mountains mixed forests are a terrestrial ecoregion of the temperate broadleaf and mixed forests biome in Southeastern Europe, according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It also is in the Palearctic realm.
Poland is part of four terrestrial ecoregions, one freshwater ecoregion, and one marine ecoregion.
The Central Anatolian deciduous forests, also known as the Central Anatolian woodlands and steppe, is a Palearctic ecoregion of the Temperate broadleaf and mixed forest biome. It is located in Central Anatolia, Asian Turkey.
The Southern Anatolian montane conifer and deciduous forests ecoregion, in the Mediterranean forests, woodlands, and scrub biome, is in the eastern Mediterranean Basin.
The Anatolian conifer and deciduous mixed forests is an ecoregion located in southwestern Anatolia, Turkey. It has a Mediterranean climate, and is part of the Mediterranean forests, woodlands, and scrub biome.
The Pannonian mixed forests is a temperate broadleaf and mixed forests ecoregion in Europe. It covers an area of 307,720 km2 in Austria, Bosnia and Herzegovina, Czech Republic, Hungary, Romania, Serbia, Slovakia, Slovenia, Ukraine, and Croatia.
The Carpathian montane conifer forests, also known as Carpathian montane forests, is a temperate coniferous forests ecoregion in the Carpathian Mountains of the Czech Republic, Poland, Slovakia, Ukraine, and Romania.
The Iberian conifer forests is a Mediterranean forests, woodlands, and scrub ecoregion in southwestern Europe. It includes the mountain forests of southern and central Spain.
The Pyrenees conifer and mixed forests is a temperate broadleaf and mixed forests ecoregion in southwestern Europe. It extends along the Pyrenees mountains which run east and west along the border between France and Spain, and includes all Andorra. The ecoregion extends from the lower slopes of the Pyrenees to its highest peaks, which include Aneto, Posets, and Vignemale.
The Alps conifer and mixed forests is a temperate broadleaf and mixed forests ecoregion in central Europe. It extends along the Alps mountains through portions of France, Italy, Switzerland, Germany, Liechtenstein, Austria, and Slovenia. The ecoregion extends from the lower slopes of the Alps to its peaks, which include Mont Blanc, at 4,809 m (15,778 ft) the highest peak in the Alps.
