Environment Canterbury (Ecan) Biosecurity Jan Crooks • Examples of habitat remaining • Native forest on aggraded river gravel • Coastal escarpment p on Old Beach Road • Threats • To native forest - smothering plant pests (OMB, banana passionfruit, german ivy, tradescantia) • To forest and tussock - wilding pines (douglas fir) Geoff Walls Ecologist working in Kaikoura Region • Priorities P i i i ffor ecosystem protection/restoration i / i • • • • Lowland native forest remnants C Coastal t l native ti fforestt remnants t (eg ( Hapuku) H k ) Lowland riparian systems Lowland wetlands (coastal, valley alluvial, hope fault depressions etc) • Limestone ecosystems • Lowland corridors (coast to mountains) • Totara forests (remnant, regenerating, restoration plantings) Geoff Walls • Threatened species protection/restoration • Hutton’s Hutton s shearwater • Endemic geckos • Weeping tree broom (Carmichaelia stevensonii) Seaward Kaikouras and Mt Alexander • Coastal tree broom (C.

Discussion • Feedback on stakeholder input? • Wh Whatt do d you wantt to t gain i outt off Immediate Steps funding? • Remember goals and targets in CWMS must be met as well (Annex G) • Protection first, restoration second, creation third • Suggestions for priority areas/habitats? Where to next? • Propose • Collate stakeholder input input, discussion today and ECan ecologist assessment • Put together g a recommended list of p priority y areas for IS funding • Agenda g p paper p and p presentation in Oct meeting g • Public consultation Oct/Nov? Housekeeping... • Decision on current Year 1 project applications • Biodiversity Biodi ersit ssub-group? b gro p? • Happy with proposed progression of priority areas?
