Rapid landscape assessment of representativeness for wildlife conservation, Hokitika Ecological District, New Zealand

Hokitika Ecological District was selected to test a methodology for the rapid evaluation of representativeness in a fragmented landscape. The methodology was based on the use of previous vegetation and soil survey reports and aerial photographs for the area, and brief field surveys. Natural vegetation types and the character of the landscape prior to human settlement were described on the basis of landform-vegetation relationships. The current landscape was described and mapped to ow modified vegetation types and land use activities. Quantitative data on the extent of natural and modified vegetation types in the former and current landscape was obtained. The results showed the degre, e to which unmodified areas are represented in the current landscape and the protected areas system. A low degree of representativeness for natural vegetation types in lowland areas was noted. Lowland areas in Hokitika Ecological District are heavily fragmented and representative wildlife conservation requires the protection and appropriate management of habitats in a wide range of modified habitats. A method for the evaluation of suitable habitats is outlined and the options for management discussed. The landscape classification and evaluation methods used in this study are reviewed and compared with those for the New Zealand Protected Natural Areas Programme
