So in habitats that have already been damaged, like the tall grass prairie here in the USA, or in mined land in various countries, restoration is already happening because of these species -- and because of this collection.
比如那些动植物生存环境已经受到破坏的地区， 像美国的大草原， 或者是许多国家的矿井地区， 这些物种使得以上类似的地区在生态上得到了修复。 多亏了这些收藏，
