Willow and Alder Guidelines

This project entitled 'Best Practice Guidelines for Willow and Alder Control for Riparian Restoration for the Waikato River' is funded by the Waikato River Authority. NZ Landcare Trust is delivering the project in partnership with Waikato Rupatu River Trust.

The aim is to develop a set of guidelines for riparian restoration, encompassing different scenarios of Willow and Alder Control. The guide will adopt an easy to read format that will assist community groups and individuals who are just starting their restoration journey.

We aim to bring together all organisations that have an interest in willows and alders within the Waikato Region to form a “think tank”.  This will involve a collaborative process, where we aim for consensus in determining the guidelines.  We will employ the services of an independent facilitator to assist with the think tank sessions as it will allow all (potentially conflicting) views to be heard and agreement to be reached by all stakeholders in a safe environment.

Project Update: February 2015

Guests gathered at Lake Koromatua on Thursday 19th February for the official launch of ‘Willows and Alders: Best practice guidelines for Willow and Alder control for riparian restoration for the Waikato River’. The innovative publication was produced by the NZ Landcare Trust and Waikato Raupatu River Trust with funding from the Waikato River Authority's Clean Up Fund. The guidelines were developed over a series of three think tank sessions, which drew upon the knowledge and experience of people from over 20 different organisations involved in willow and/or alder control.

Project Update: July 2014

The three think tank sessions were chaired by an independent facilitator with assistance from NZ Landcare Trust Project Coordinators and provided a valuable platform for discussion around willow and alder control.

The first think tank session took place on Tuesday 11th March and included useful early discussions around what the guide should include, as well as general discussion on willows and their positive and negative impacts on the environment. In the second session, different case studies were brought to the table to highlight various aspects of willow control as well as uses for sterile willow species in bank stabilisation situations. The third session focused more on the layout of the guidelines and what should and should not be included.
