European brown hares inhabit landscapes including terrestrial forests, terrestrial meadows and steppes, and shrublands, at elevations up to 800 meters. The species occupies biomes such as temperate mixed forests with warm summers and many oak, birch, and maple trees; flooded meadows where water frequently covers the ground and there is abundant grass; temperate steppes with plentiful grass and few trees, experiencing rainfall; and taiga characterized by cold winters and numerous coniferous trees including spruce and pine. The climate varies, with summers ranging from cool to warm, never hot, between 15 and 25 degrees Celsius, and it is consistently very wet with frequent rain and high humidity. Rainfall is abundant, resulting in cool summers and snow in winter; some areas experience warm, pleasant summers with ample rainfall; and winters are not extremely cold.
