A little piece of South Wairarapa's heritage is now protected after an open space covenant was put in place at Wairio Station this week.
The Buddle Findlay Flaxland is a 9ha covenant on land farmed by Grant and Carina McGhie, a wetland with flax plants up to 3m tall and a rare swamp nettle found in just a few places in Wairarapa.
Wairarapa QEII National Trust Representative Trevor Thompson said the wetlands are a small patch of what's left of flax grown in the flax industry boom from the 1860s to 1930s.
"It left a long time ago, and what you're going to see are a couple of pieces of flax that were left from those days. It's a significant habitat that is almost all but gone. It doesn't look pretty at this point ... but from now on it's all upwards."
Over the last year, a team has planted 3000 flax plants seeded from the original flaxlands and 1000 cabbage trees, and pulled out willows and other pest plants.
