Extract from: Management and Research Priorities for New Zealand Braided Rivers (DOC 3MB PDF)

“Braided rivers in New Zealand support unique communities of plants and animals and many threatened species. However, these communities are subject to a number of threats, particularly predation, weed invasion, water abstraction, dams, modified flow regimes for electricity generation, flood protection works and human recreational activities on rivers. The result of these activities is that biodiversity values in braided rivers are in decline. However, in recent years, public awareness of the biodiversity values of braided rivers and threats to these values has increased. The number of initiatives to undertake conservation work within braided rivers has likewise increased. At the same time, greater demands are being placed on braided rivers, particularly as sources of water for irrigation and hydro development, but also for gravel extraction and recreational purposes such as jet-boating, four-wheel driving and fishing.

The vision for biodiversity recovery is that New Zealanders will value and enjoy braided river ecosystems as a unique and integral part of their natural heritage. People with an interest in conservation, management or use of braided rivers will support ongoing, sustainable local conservation programmes, and these will be demonstrably successful in maintaining and improving indigenous biodiversity of braided rivers. This document emphasises ecosystem and multi-species approaches to addressing the decline in biodiversity values, with a focus on conserving indigenous species that specifically depend on braided rivers (including a range of threatened species).

Current knowledge of the biodiversity values of braided rivers and the conservation management of these values is extensive. However, there is a clear need to improve conservation outcomes
for braided river ecosystems and species through the development of a better understanding
of the ecology of braided rivers and the development of more-effective management tools.

This document aims to assist this process by providing guidance on current ‘good practice’
f or managing biodiversity on and in braided rivers, priorities for management and future research, and by promoting co-operation among a range of stakeholders (including all levels of government, institutions, iwi, community groups, and local people and businesses) to conserve braided river ecosystems and species.”

This document:

1. Describes our vision for the conservation of biodiversity on braided rivers.

2. Provides an overview of braided rivers ecosystems and the factors that influence them, in the context of conservation of indigenous biodiversity, and particularly threatened species.

3. Summarises current ‘good practice’ for managing biodiversity on braided rivers and uses a range of case studies as examples.

4. Identifies and prioritises specific management and future research actions in relation to the main factors that directly impact braided river ecosystems.

Vision

New Zealanders will enjoy and care for braided river ecosystems as a distinctive a valued part of their natural heritage. Stakeholders will support ongoing, sustainable conservation programmes, and these will be demonstrably successful in maintaining and improving the indigenous biodiversity of braided rivers.
