Integrated Catchment Management

Tadmor River

Introduction

High quality freshwater is one of New Zealand’s most important natural assets and a resource that is at enormous risk. Good management of water resources requires a firm understanding of the effects of adjacent land management on water quantity and quality, the equitable allocation of water for out-of-stream and in-stream uses, and potential connections between freshwater and coastal ecosystems.

Information on the holistic management of water resources for large and complicated catchments, like the Motueka, is very limited. Rainfall, geology and land use varies across the catchment therefore information collected in one area is not necessarily applicable in another.

Particular concerns have been raised over the condition of the Motueka River catchment in the last few years. Annual surveys of brown trout over the last 6 years have consistently shown that the observed number of adult trout were about one third of the numbers seen in 1985. The reasons for this decline are unclear but could relate to changes in physical habitat suitability for adult trout in the main river, spawning success in the tributaries, and/or declines in food availability.

Water allocation from the catchment is also coming under increased scrutiny. Consequently, important decisions need to be made regarding the amount of water that can be abstracted from the river without having harmful effects on aquatic life in the river.

This research will provide information to enable informed decision-making on issues that will affect freshwater resource management at large scales.
