Plant Pest Control

 

Our services include clearing scrub and invasive plant pests from farmland for increased productivity, controlling wilding conifer populations, clearing land for native plantations or forestry projects.

Every member of our team has industry-based skills and training and we can offer a number of different pest eradication methods to suit both your budget and the terrain.

Wilding Conifers

 

Over the past five years, Longridge contracting has been heavily involved in the National Wilding Conifer Control programme, which was established by MPI in 2016. We have successfully completed our eradication work over substantial tracts of land in the Mackenzie country, Craigieburn Ranges and the Waiau area. Conifers, which can carry hundreds of seeds in the form of pinecones, are prolific spreaders, and can cause enormous damage if they escape the confines of a planted area. They are a huge and ongoing threat to New Zealand farms, biodiversity and our native landscapes. The main conifer species at risk of spreading are: - Douglas fir (Pseudotsuga menziesii) - Scots pine (Pinus sylvestris) - Lodgepole or contorta pine (Pinus contorta) - Dwarf mountain pine and mountain pine (Pinus mugo and P. uncinata) - Bishop pine (Pinus muricata) - Maritime pine (Pinus pinaster) - Ponderosa pine (Pinus ponderosa) - Corsican (black) pine (Pinus nigra) - European larch (Larix decidua) - Radiata pine (Pinus radiata)

Gorse & Broom

Gorse is a scrub weed, introduced from western Europe in the early 1800s as a form of hedging for farmland. Gorse is easily distinguishable from other plant species and is famous for its thorny leaves and yellow flowers.​ - Gorse can spread quickly over large distances; picked up by the wind or in the fur/ fleece of passing animals. - Growing very quickly and densely, it competes with grass-based pastures and exotic forests for water, light and space. - Prone to drying out over the summer months, gorse can increase the risk of fire.

Nassella tussock

Nassella tussock (Nassella trichotoma) is an invasive grass species, originally from South America. Mature plants can produce up to 100,000 seeds, which are dispersed by wind, water, stock, clothing, and machinery. Although most seeds only survive one to two years on the ground, some can remain viable for much longer. It can take three to four years for a seed to germinate and grow large enough to be detected. We can assist you with destroying nassella on your property, either by hand removal (grubbing) or chemical removal. Contact us early to secure your spot.

Native Planting and Restoration

Longridge contracting have completed numerous native planting and poplar planting projects around the South Island. No job is too big or too small. We work in with North Canterbury based nursery and planting business Hurunui Natives and other contractors, to source the healthiest and most reliable plants, and our team work quickly and efficiently, even in very steep terrain. As much as we enjoy controlling plant pests, we also appreciate the opportunity to give back. The restoration of native habitats, alongside the creation of shelter belts, gives every member of our team genuine satisfaction.
