Most of Germany has a temperate seasonal climate in which humid westerly winds predominate. The climate is moderated by the North Atlantic Drift, the northern extension of the Gulf Stream. This warmer water affects the areas bordering the North Sea; consequently in the northwest and the north the climate is oceanic. Rainfall occurs year-round, especially in the summer. Winters are mild and summers tend to be cool, though temperatures can exceed 30 °C (86 °F).
The east has a more continental climate; winters can be very cold and summers very warm, and long dry periods are frequent. Central and southern Germany are transition regions which vary from moderately oceanic to continental. In addition to the maritime and continental climates that predominate over most of the country, the Alpine regions in the extreme south and, to a lesser degree, some areas of the Central German Uplands have a mountain climate, characterised by lower temperatures and greater precipitation.
The territory of Germany can be subdivided into two ecoregions: European-Mediterranean montane mixed forests and Northeast-Atlantic shelf marine. As of 2008 the majority of Germany is covered by either arable land (34%) or forest and woodland (30.1%); only 13.4% of the area consists of permanent pastures, 11.8% is covered by settlements and streets.
Plants and animals are those generally common to middle Europe. Beeches, oaks, and other deciduous trees constitute one-third of the forests; conifers are increasing as a result of reforestation. Spruce and fir trees predominate in the upper mountains, while pine and larch are found in sandy soil. There are many species of ferns, flowers, fungi, and mosses. Wild animals include deer, wild boar, mouflon, fox, badger, hare, and small numbers of beavers.
The national parks in Germany include the Wadden Sea National Parks, the Jasmund National Park, the Vorpommern Lagoon Area National Park, the Müritz
