Species diversity in natural grasslands is high.

天然草原的物种多样性很高。

We find a surprising area of natural grassland on both islands of New Zealand, a country otherwise dominated by temperate forests owing to its Oceanic climate.

我们在新西兰的两个岛屿上发现了令人惊讶的天然草原，而新西兰由于属于海洋性气候，所以主要以温带森林为主。

As mentioned, most of these areas of natural grassland have vanished, being replaced by agriculture, such is the quality of their soils and climatic suitability for cereal crops.

如上所述， 这些天然草原大部分已消失，取而代之的是农业用地， 这些地区的土壤质量和气候都非常适合种植谷物。
