. Plants around Jigokudani Valley

Although the elevation of Jigokudani Valley is only 210 to 260 meters, such alpine plants as Marsh tea, and Crowberry, grow there. This is because the surrounding environment is very severe for plants due to such emitted gas as hydrogen sulfide or the presence of the highly acidic and moisture absorbing grass. Such severe conditions, like severe weather on high mountains, impede growth of plants other than Alpine plants.
