Crown Pastoral Land Tenure Review Lease name : GLENCOE (North Otago) Lease number : PO 366 Conservation Resources Report - Part 1 As part of the process of Tenure Review, advice on significant inherent values within the pastoral lease is provided by Department of Conservation officials in the form of a Conservation Resources Report. This report is the result of outdoor survey and inspection. It is a key piece of information for the development of a preliminary consultation document. Note: Plans which form part of the Conservation Resources Report are published separately. These documents are all released under the Official information Act 1982.

Early tenure review surveys were generally not as comprehensive as those that are undertaken today and the use of additional tools (e.g. LENZ and structured SIV Guidelines) are now available to assist with assessment of ecological patterns and values present. A re-inspection therefore presented the opportunity to both examine the original proposed designations and to consider any major deficiencies in the original proposal. The re-inspection of the PL was undertaken on 17 November 2009, for the purpose of determining if changes were required to the initial Conservation Resources Report (CRR), which was based on information derived from the original inspection carried out in November 1998. The re-inspection team consisted of Tony Perrett (High Country Tenure Review Manager), John Barkla (Technical Support, Biodiversity Assets – vegetation), Shar Briden (Technical Support – Historic) and Fiona Hall (Technical Support – Recreation). It is important to note that the original assessment and recommendations were done over ten years ago. However, most of the original proposed designations have been reconfirmed as retaining natural heritage and the recommendations made in this report improve and compliment these. This addendum document is to be read in conjunction with and as an addition to the original CRR. The original DOC recommendations relating to the 1998 CRR recommended protection of a wide range of landforms, plant and fauna communities by way of return to full Crown ownership. The area recommended covered the majority (63%) of the small PL. Progress on negotiations failed to materialise in part due to grazing not being made available in the lower part of the proposed Conservation Area. A different approach is required to progress negotiations and the new DOC recommendations have been designed to achieve this and also to take account of new government high country policy whilst meeting the objectives for tenure review as contained in the Crown Pastoral Land Act. Additional areas have also been identified as containing significant inherent values, based on the application of the current version of the SIVs Guidelines. In particular the significance of a raised rim pit considered to be a probable umu was noted by DOC. docDM-540985 - Glencoe (Nth Otago) CRR Addendum 20103 3 RELEASED UNDER THE OFFICIAL INFORMATION ACT PART 2 INHERENT VALUES: DESCRIPTION OF CONSERVATION RESOURCES AND ASSESSMENT OF SIGNIFICANCE The following description and assessment of inherent values is to be read in conjunction with the original CRR. 2.1 Land Environments of New Zealand (LENZ) There are two databases that have been used to assess biodiversity protection (Walker et al 2003). 1. Environmental distinctiveness has been assessed through the Land Environments of New Zealand (LENZ). This is a classification of New Zealand landscapes using a comprehensive set of climate, landform and soil variables chosen for their roles in driving geographic variation in biological patterns (Leathwick et al 2002 & 2003). It is presented at four levels of detail containing 20, 100, 200 or 500 environments nationally. The most detailed is called LENZ Level IV. 2. The area of unprotected indigenous cover in threatened land environments has been identified in the national land cover database (LCDB). From the above databases, spatial data depicting indigenous cover and legal protection were overlaid on LENZ Level IV environments to identify biodiversity that is most vulnerable (most likely to be lost). This provides a measure for: a. percentages legally protected and; b. percentages of remaining indigenous cover Based on these two criteria, five categories of threatened environments have been used to identify environments containing indigenous biodiversity at most risk of loss. They are classified as follows: 1. Acutely threatened: <10% indigenous cover remaining 2. Chronically threatened: 10-20% indigenous cover remaining 3. At risk: 20-30% indigenous cover remaining 4. Critically underprotected: >30% indigenous cover
