Appendix 1 Schedule of infestation sites on lands administered by DOC
View the Schedule of infestation sites on lands administered by DOC (PDF, 447K)
This schedule lists all known wilding conifer infestations that threaten DOC-administered land in the South Island. The schedule has been compiled from Area Weed Control Strategies, Conservation Management Strategies, Protected Natural Area Programme reports, comments from DOC staff, and personal knowledge of some infestation sites.
The schedule is unlikely to be complete. Many areas threatened by wilding conifer spread are poorly known, and many have not been surveyed. The wilding conifer species that threaten some sites, and the biodiversity values at risk, are frequently not known or not clear. And, wilding conifers can invade new areas so quickly, new infestations may not yet be reported.
This Schedule of Infestation Sites is modeled on the spreadsheet of site-led programmes in Appendix 2 of Invasive Weed Threats: Weed-led and Site-led programmes identified by the Department of Conservation, June 1998 (Owen, 1998b). The main difference between the wilding conifer schedule (attached) and the site-led programme spreadsheet (Owen, 1998b) is that the former is primarily concerned with wilding conifers, whereas the latter considers all weed threats.
The purpose of the schedule is to identify (as part of the Wilding Conifer Strategy) the priorities for wilding conifer control in the South Island of New Zealand. Infestation sites are listed in order of priority for control using the following criteria:
- The total score, from 21 (highest priority) to 1.5 (lowest priority); then,
- Whether wilding conifers, or other invasive weeds, pose the main threat to the site. Sites where wilding conifers do not pose a significant threat are ranked lower than sites where they do; i.e. infestation sites where the urgency score for conifers is lower than the score for other weeds (these sites are marked with an asterisk (*) in the 'total score' column); then,
- The risk of re-infestation at the site (ranked 'low', 'low-medium', 'medium', 'medium-high', or 'high'), where low risk sites are ranked higher; then,
- The size of site, where small sites are ranked higher than large sites.
(Only sites scoring 12.5 or more are further sorted at stages 3 and 4)
The final priorities for wilding conifer control at each site may be influenced by other factors beyond the detail or scope of this strategy.
Methodology for interpretation of the schedule
Management Unit Name / Infestation Site Name
(column 1):
Lists the management unit and the infestation site within the management unit that is threatened by wilding conifers. A slash ' / ' separates the management unit name and infestation site name. Note that all management units threatened by wilding conifers are included, even if the present wilding infestations or seed trees are located outside the management unit and/or on land not administered by DOC.
Area Office (column 2):
Lists the DOC Area within which the management unit is located. Abbreviations for Areas, with the location of Area offices in brackets, are:
AO Aoraki (Mt Cook)
BU Buller (Westport)
CE Central Otago (Alexandra)
CO Coastal Otago (Dunedin)
GB Golden Bay (Takaka)
GR Greymouth (Greymouth)
MO Motueka (Motueka)
MU Murihiku (Invercargill)
NC North Canterbury (Christchurch)
RU Raukapuka (Geraldine)
SA St Arnaud (St Arnaud)
SI Southern Islands (Invercargill)
SM South Marlborough (Blenheim)
SO Sounds (Picton)
TA Te Anau (Te Anau)
TW Twizel (Twizel)
WA Waimakariri (Arthur's Pass)
WK Wakatipu (Queenstown)
WN Wanaka (Wanaka)
Area Under Threat (column 3):
Quantifies the area (in hectares) within the management unit that is likely to be affected by wilding conifers in 10-15 years if no control is undertaken. At some sites it is difficult to determine with accuracy the area affected by wilding conifer spread. The figures in this column must, in many cases, be regarded as estimates.
Rank Scores - Botanical (column 4):
Identifies the Botanical Score for the management unit, based on the Six-Point Scoring System outlined in the Department of Conservation Strategic Plan for Managing Invasive Weeds (SPMIW) (Owen, 1998a). Threatened plants, and the threat categories (critically endangered, endangered and vulnerable), are those listed in the most recent published list of threatened plants (de Lange et al, 1999).
Rank Scores - Wildlife (column 5):
Identifies the Wildlife Score for the management unit, based on the Six-Point Scoring System outlined in the DOC SPMIW (Owen, 1998a). Endangered, rare, and restricted species are those listed as 'Category A' or 'Category B' species in the DOC publication Setting Priorities for the Conservation of New Zealand's Threatened Plants and Animals, (Tisdall, 1994) (Second Edition of Molloy and Davis, 1992). These species are recorded as 'Cat.A' or 'Cat.B' species in the schedule.
Rank Scores - Urgency (column 6):
Identifies the urgency of weed control in the management unit, based on the Criteria for Assessing Urgency of Control in the DOC SPMIW. Where the 'wilding conifer species' present in the unit are less invasive than other invasive weeds present in the unit, this is indicated by a second score in this column and an asterix ' * ' in the total score column (column 7).
Rank Scores - Total Score (column 7):
The Total Score is the higher of the botanical and wildlife scores multiplied by the urgency score. The risk of re-infestation is also noted in this column.
Important Natural Values of the Management Unit
(column 8):
Describes the main plant communities present in the management unit and specifies the characteristics of those communities, or species within the communities, upon which the botanical and wildlife scores are based. Plant community descriptions are based on the structural classes proposed by Atkinson (1985).
Threat Posed to the Management Unit by Invasive Weeds (column 9):
Describes the impacts that invasive weeds are expected to have on the plant communities and/or wildlife habitat of the management unit over 10-15 years if no weed control is undertaken. Actual or potential impacts on landscape character, historic values, cultural values, or recreational opportunities are also noted.
Objectives of Wilding Conifer Control Programme
(column 10):
Describes the actions required to protect the plant communities and/or wildlife habitat of the management unit from the wilding conifer species that threaten the management unit.
Wilding Conifer Species threatening the Management Unit (column 11):
Lists the wilding conifer species that threaten the plant communities and/or wildlife habitat of the management unit. Wilding conifers are all those naturalised species within the Gymnospermae (Class Coniferopsida), and include all species within the Araucariaceae, Cupressaceae, Pinaceae, and Taxodiaceae families. Naturalised species within these families, and the common and scientific names for these species, are as listed in the Flora of New Zealand Volume IV (Webb, Sykes, and Garnock-Jones, 1988). (see species list below)
Other Pest Species threatening the Management Unit (column 12):
Lists all other significant weed and animal species that threaten the plant communities or wildlife habitat of the management unit. Ubiquitous herbaceous species that are not normally controlled are not recorded unless they pose a significant threat to the values of the management unit. Species listed are those recorded in existing weed strategies, inventories, or in the literature. It is likely that not all species, especially animal pest species, are recorded. (see species list below)
