Poplar Demonstration - watch out for it!

Posted on February 12, 2020

The purpose: to show the features of different hybrid poplar clones being bred in New Zealand for soil stabilisation, shelter, shade, riverbank protection, timber, and carbon credits.

The location: signposted on State Highway 1 between Utiku and Taihape. The site is ~ 100 m from the road in clear view. Look out for it on your travels.

Plates 1-4. Views of the sign and planted poplars. Rows run up the hill.

Establishment: Poles (3 m) were planted using an augur, and protected with Dynex sleeves. Cattle were excluded with a solar-powered electric 2 wire fence. The poplar trees were planted in winter 2017 in rows extending up the slope, one clone per row, with spacing between rows of 10 m and within rows of 7 m.

The hybrid poplar clones:
