Thinning Old Man Poplars

In winter 2009 work was carried out at a property on State Highway 1, in the Rangitikei District. The work involved thinning the Old Man Poplars (OMP) that had not been managed over their lifespan. The trees were starting to cause problems on the farm by falling and making it unsafe for stock and farm personnel.

Tunnel Gully Erosion

Tunnel gully erosion not only creates hazards for people and stock but it also causes the loss of pro- ductive land and siltation downstream. Pole planting is a key management technique available to to stablise susceptible land.

Development of Water Management Zones in the Manawatu-Wanganui Region: Technical Report to Support Policy Development

The water management zones support the policy framework for surface water allocation, surface water quality and activities in the beds of rivers and lakes including structures and flood protection works. This report describes how the water management zones and subzones were defined.

Identifying Community Values to Guide Water Management in the Manawatu-Wanganui Region

The values framework that underpins the One Plan is based on extensive community and stakeholder consultation. This document defines the framework and sets out a process by which it can be incorporated into the One Plan.

Lake Horowhenua Review: Assessment of Opportunities to Address Water Quality Issues in Lake Horowhenua

This Ministry of Science and Innovation Envirolink report provides a review of the available information on Lake Horowhenua and an assessment of opportunities to address water quality issues in the lake.

Restoration Plan for Lake Horowhenua

A restoration plan for Lake Horowhenua prepared for Horizons Regional Council by the National Institute of Water and Atmospheric Research that reports strategies to improve/benefit lake water quality.

2013 Assessment of fish populations in Lake Horowhenua

As part of lake restoration efforts by Horizons Regional Council and the Lake Horowhenua Trustees, a survey of fish species in Lake Horowhenua was conducted by the University of Waikato using boat electrofishing and fyke netting. The purpose of this survey was to determine the abundance and diversity of fish species within the lake and to ascertain if pest fish species were present at biomasses high enough to be negatively impacting on lake ecology.

Delimitation of submerged weed bed areas in Lake Horowhenua

Horizons commissioned NIWA to undertake a sonar survey of the bed of Lake Horowhenua, focused on mapping the areas of high weed cover, so as to estimate areas for harvesting. This brief report confirms the methodology employed, provides maps of the lake bed distribution of weed beds, a description of weed bed features and calculated areas of dense vegetation.

Lake Horowhenua Action Plan

In August 2013, five parties signed an Accord to provide leadership, halt the degradation and put in place remedial measures on Lake Horowhenua and Hokio Stream that will ensure these taonga hold pride of place in the Horowhenua Community. This Action Plan sets out how the parties will address issues affecting the Lake from 2014-16.

Water Quality Guidelines to Protect Trout Fishery Values

There are four key water quality parameters for the protection of trout fishery values. This report describes these and recommends guidelines for each in relation to trout life-stage and activity.

Water Quality State and Trends in the Horizons Region

This report assesses the current state and recent trends in river water quality in the Horizons Region. For this report, depending on the individual site, data from 1978 to 2009 has been used.
