Willow Vegetation for Managing River Edges

The art of balancing community expectations, cost, and politics in an environment of climate change. There is no ‘one size fits all’ tool in the river management toolbox, particularly when it comes to balancing expectations from numerous stakeholders about what’s best. Policy, affordability, politics, and science all play a part.

Performance of bioengineering solutions (poplars and willows) for riverbank protection during Cyclone Gabrielle

This project looked at how bioengineering functioned within Hawke’s Bay and Tairāwhiti, including performance in relation to flood flow effects, erosion control, stopbank protection, interception of silt and woody debris, and benefits to downstream receiving environments.

Poplars and willows as bioengineering solutions – learnings from Cyclone Gabrielle

McIvor I, Heslop I, Brooks F

A survey of the bioengineering works (primarily mature willows and poplar trees) on a) the Tūtaekurī River within the Heretaunga Plains Flood Control Scheme and b) the Te Ārai River from Gisborne City water intake to its integration into the Waipoua Flood Protection Scheme was conducted 13 months after Cyclone Gabrielle.

Root development in poplar and willow clones (a pot study) - Research Brief 05

A range of willow (Salix) and poplar (Populus) clones were used in the study. This information is important for river engineers, land managers and landowners seeking to match planting material to situation.

Willows at work in the catchment - Research Brief 11

Natural water catchments extend from mountains to sea, collecting water on the way. The erosive power of flowing water increases during periods of high water runoff, e.g. rainstorms. The heavier the rainfall the greater the water volumes and velocity the greater the erosive forces.
