標高の変化が作る、植物の多様性
奥日光の特徴のひとつが、1,200m～2,500mにまで及ぶエリア内の標高に起因する植生の多様性です。
標高が100m高くなるにつれ約0.6度気温が下がり、高度によって植生が変化します。山地帯のミズナラ、より高い位置にある亜高山帯のコメツガ、もっとも標高の高い高山帯のコケモモなどが生育しています。奥日光ではこのように、好湿植物の生きる湿地と、山々などが混在した環境が存在するのです。

Plant Diversity Created by Rising Altitude
One of the key features of Oku-Nikko is the diversity of flora resulting from the altitude of the area spanning 1,200 to 2,500 meters. For every 100 m increase in elevation, the temperature drops around 0.6°C, and the flora changes with elevation. The lower reaches of the mountains are dominated by Japanese oaks (Quercus crispula Blume), Northern Japanese hemlock are found (Tsuga diversifolia) in the higher sub-alpine zones, and Lingonberry (Vaccinium vitis-idaea) in the highest alpine zones. Oku-Nikko is thus a highly complex environment since the mountains are combined with wetlands, with their many moisture-loving plants.
