Practical information on what to plant, and fire risk tips for people living in rural areas.
Fire and Emergency New Zealand has advice on understanding your fire risk and protecting your property from fire.
Plant pests, or weeds, are one of the greatest threats to biodiversity in New Zealand. Weeds can prevent natural regeneration of natives as well as impact established forest on neighbouring lands.
Unfortunately, weeds are often more efficient than natives in establishing after fire. Gorse, blackberry and Californian thistle are coming back in force on burnt areas and need to be controlled so that quick-growing natives such as bracken and poroporo can establish instead. These natives provide an important role in stabilising the soils while still allowing for seeds dispersed by birds to establish and grow.
Weed control and ongoing plant maintenance are critical to the success of any restoration planting.
Advice on how to identify and control weeds can be found at www.ecan.govt.nz(external link).
Environment Canterbury has a guide on options for erosion and sediment control [PDF, 894 KB] and advice on when consents might be needed for fire recovery work [PDF, 53 KB].
Planting fast-growing native species that are found naturally on the Port Hills will provide habitat for native wildlife and a seed source for natural regeneration, as well as shelter for larger, slower-growing natives such as tōtara (Podocarpus totara).
There can be an amazing amount of variety between the same species of plant growing in different areas; in form, size and leaf shape. By growing plants specific to different ecological areas we protect this diversity. The plants are also more likely to survive as they are specifically adapted to the conditions at this site.
Eco-sourcing ensures genetic purity by growing plants from seeds or cuttings collected from their original habitat or source.

Under the right conditions, any plant will burn but some plants are less flammable than others. You can create a ‘green firebreak’ by using low-flammable plants.
Poroporo (Solanum laciniatum) is quick-growing and has very low flammability. It’s not normally used in restoration projects but it will quickly provide ground cover to help suppress gorse and other weeds. Other species can be planted later and will start to naturally suppress the poroporo as they grow.
Note that some species will require shelter from frosts or wind. Visit www.lucas-associates.co.nz/ecosystems/porthills.html(external link) for guidance.
These nurseries stock eco-sourced native plants. Motukarara and Wai-ora Landscapes only stock local eco-sourced plants. Trees for Canterbury also stock variegated natives and cultivars so ask their friendly staff for advice when purchasing.
