The eponymous Pampas grass is found in that South American grassland, while the equally eponymous Veldtgrass (Ehrharta calycina) is from South Africa, and in the New Zealand tussock grasslands, Chionochloa is common.

同名的潘帕斯草生长在南美草原，同名的草原草（Ehrharta calycina）则产于南非，而在新西兰的草丛草原上，Chionochloa 则很常见。

The causes of these " Tussock" grasslands are poor soils in the centre of the North Island, and a rain shadow in the South Island east of the Southern Alps that reduces rainfall significantly.

形成这些“丛生” 草原的原因是北岛中部土壤贫瘠，而南岛南阿尔卑斯山以东的雨影区导致降雨量大幅减少。
