Understanding Natural Character in Marlborough District Rivers: A Comprehensive Assessment

This document provides an in-depth analysis of the natural character of rivers within the Marlborough District. Featuring contributions from experts like James Bentley, Alan Rackham, and MDC personnel, it explores natural elements, patterns, and processes while assessing the extent of human influence. A peer review process has been integral to developing a robust understanding, with initial concerns regarding purpose and methodology addressed through collaborative debate. The assessment evaluates 38 river segments, ultimately ranking their natural character within a defined scale, fostering greater insights into river management and conservation.

  4. Primary Attributes • River channel • River Shape • Flow regime • Water Quality • Absence of exotic flora/ fauna • Structures/ human modification

  5. Primary Attributes contd • Riparian edge • Extent of native flora • Structures/ human modification • Wider Landscape • Landscape character

  6. Result • Assessed 38 rivers/river segments • Potential range of natural character from 8-40 • Actual range 16-40 • Initial concerns with purpose and process • Worked through; takes time • Debates between ‘river experts’ robust • Ultimately considerable agreement

  7. Points of Difference/Issues • 5 point scale to rank each attribute • Concerns about adding ordinal data • Debate about what natural character is not yet resolved • Few objective measures; relies on expert assessments which may vary between regions • Peer review still continuing; some issues but largely complimentary
