53 Area Objective Treatment Timeframe Figure A – Offset Planting Vent Shaft Offset To offset for the loss of vegetation and habitat associated with the vent raises in Area 1. To recreate complex broadleaf native forest habitat with species and vegetation tiers consistent with the Coromandel Forest Park (CFP). To provide an extension of habitat for native fauna in the CFP. To promote natural reseeding from the CFP. General ecological and landscape enhancement. Stock and pig exclusion. Low density native planting with suitable broadleaf species, for example kanuka (Kunzea robusta), pigeonwood (Hedycarya arborea), mahoe (Melicytus ramiflorus). Once established (3-5 years), enrichment planting with specimen tawa (Beilschmiedia tawa), miro (Prumnopitys ferruginea), pukatea (Laurelia novae-zelandiae) and rimu (Dacrydium cupressinum) Planting should be staged to support natural forest regeneration processes particularly where natural seedling establishment is observed. Weed control. Mammalian pest control. Pioneer planting completed by the end of the first planting season following vegetation clearance for vent shafts within Area 1. Enrichment planting of future canopy species once the pioneer plantings have reached a sufficient size to shelter enrichment species (likely to be between 3 and 5 years following pioneer planting). Figure A – Other Planting Screen planting To visually contain and assimilate landform modification and screen associated surface infrastructure area from Willows Road (including the unformed paper road) and adjoining rural dwellings Stock exclusion; Site preparation; Standard mass planting of riparian and adjoining terrestrial areas using representative native pioneer species and non-invasive exotic shelter belt in specified area; Enrichment with future representative canopy species once the pioneer plantings have reached a sufficient size to shelter enrichment species; Establishment of a shelterbelt in the location shown in Figure A; Planting complete within the first planting season following the completion of bulk earthworks in Area 2 associated with the establishment of the Willows Road Surface Facilities Area.
