阿蘇の草原


総面積380km²の阿蘇カルデラの風景は、山、草原、湿地で構成されています。この内、草原は約220km²を占めています。阿蘇カルデラの特徴でもあるこれらの草原は、草地、沼地、牧草地などの自然・半自然のエリアと農耕のための植物を植えられた人工的なエリアで作り上げられています。


特定の地理的位置と気候条件のおかげで、阿蘇の草原は多様な植物や動物が繁栄する豊かな自然生態系を作り上げることができています。この地域には大きな家畜棲息地があります。農業は地域の人々に適合し成功した産業でもあります。これらの草原は、九州の貯水池としても知られており、ここには雨水を貯める天然の地下水槽があり、九州北部に約500万人の人々が使用している純粋でミネラル豊富な水を生産しています。

この草原地帯は、春の野焼きや伐採、牧草地としての利用などの人の手によって、急速に育つ木々がこの地帯を森にしてしまわないよう、守られているのです。

Aso Grassland


Covering a total area of 380 km², the landscape of the Aso Caldera features mountains, grasslands, and marshes. Grasslands account for approximately 220 km² of the total caldera area. These grasslands are a unique feature of the caldera, being made up of both native, semi-natural areas including meadows, pasture land, thatch fields, and marshes, as well as areas in which grasses and plants have been introduced and cultivated.


Thanks to their geographical location and the local climate, the Aso grasslands support a rich natural ecosystem in which a variety of plants and animals thrive. The area is home to a large livestock population. Agriculture flourishes, having been successfully adapted to the local conditions and the specific needs of the people here. These grasslands are commonly regarded as the reservoir of Kyushu, with natural underground water reservoirs storing rainwater in porous volcanic strata. The pure, mineral-rich water is supplied to around five million people in northern Kyushu.


These grassland areas have been managed so that invasions by fast-growing shrubs and trees, and subsequent forestation, have been avoided. Management of the land includes spring burnings, cutting, and maintaining cattle pastures.
