Removing wilding conifers and enhancing the entrance to Alexandra

Located in the heart of Central Otago, Alexandra has a range of parks and reserves scattered across the town providing for a number of recreational activities. The 15-hectare Half Mile Reserve is located to the south of the bridge that crosses the Clutha | Mata-Au River.

Boffa Miskell was engaged to create a concept package for the reserve that would identify the ways existing groups use the current site, provide guidance on native planting that can withstand the dry harsh Alexandra climate, and include a design that showcases archaeological features that are located throughout the reserve.

Central Otago District Council identified that wilding pines on Half Mile Reserve have been causing seed spread and need to be removed because of the prevailing nor ’wester disperses the seed in an easterly direction. Wilding conifers can have significant adverse effects on landscape values, and potential to transform non-treed landscapes which have unique and defining qualities for Alexandra.

The masterplan for Half Mile Reserve looks to take a light approach with minimal amenity intervention. The site will be reflective of the surrounding Central Otago Landscape.

Native tree planting is proposed along the northern boundary to provide a break for the residents to the north from the prevailing southerly winds. A shelter belt is proposed behind the native planting to provide a quick and fast-growing wind break that can then be removed once the natives have established.

Informal trails will be retained. It is intended that the space provide an opportunity for the user to explore the site on their own accord. Minimal signage would be used to highlight historic features such as the mining artefacts.

Existing tors are prominent across the western portion of the reserve. Removing the wilding pines has revealed these unique features and it is proposed to keep the area open for people to explore the space as they wish.

Small pockets of native planting have been included in the central part of the eastern section of the site, around the existing grassed area. It is intended that these natives would be low maintenance and drought tolerant which require little care once established and would eventually self-seed across the site.

The plan was approved by council and the wilding pines have been felled. Central Otago District Council will implement the reserve design over the next few years.
