Overview

2.1 Contract overview
The Pareora Berm transition will see the installation of 7,200 plants into mixed poplar and native
plantings to strengthen the berms around an area known as Evan’s crossing on Pareora Ford road.
We are looking for a supplier with a proven track record of good project management and delivery
of quality targeted weeding and native enhancement works of this scale.
2.1.1 Background
River berms and margins are the strips of land directly beside the river, or between the river and
the stopbank. Berms have an important function in flood protection by adding capacity to the main
river channel by carrying water when the river is high, slowing down the flood flow to mitigate
erosion risk, and absorbing excess water into the ground. Planting trees on these berms is
essential for flood resilience and protection as they provide a buffer to slow floodwaters and
prevent bank erosion. Currently, most river berms in Canterbury are choked with exotic weed such
as Old Man's Beard which is likely to worsen with climate change.
Weed infestation is a region-wide issue that compromises the health of trees and the performance
of the berm during flood. Environment Canterbury’s (ECan) annual river maintenance involves
chemical spraying and mechanical control of a range of weeds, but it is difficult to keep up. A more
sustainable method of controlling weeds is to both control the target species and manipulate the
environment to the disadvantage of the weed species. This ultimately reduces future weeding
efforts.
The Berm Transition Project is one of Environment Canterbury’s six Climate Resilience
Programme of Flood Risk Management Projects which is part-funded by the Ministry for Business,
Innovation and Employment's Kānoa - Regional Economic Development & Investment Unit (Kānoa
– REDIU). The goal of this project is to transform selected areas within the braided river berms into
multi-functioning areas, increasing their value, resilience and function. These areas will then
provide examples to inspire future management. It takes time to build resilience and we have a
transformational opportunity with the $10m of the funding to fuel this project to protect the health of
our flood protection vegetation and accelerate the regeneration of this important green asset.
We will achieve this with effective, strategic planting arrangements that will grow into dense,
stratified riparian plantings
