There was an article in one of the New Zealand newspapers last week about Earnscleugh Station that farms 25,000 (yes, 25,000!!) Merino sheep in New Zealand. We were delighted to see the article mention the snowgrass tussock that the merino sheep feed on high up in the mountains. Snowgrass Merino Clothing is named after this same tussock which is the staple diet for the merino sheep when they are let to roam the mountains. It also happens to be the diet of the endangered Takahe bird, which is only found in New Zealand.
