We pride ourselves in conducting effective invasive weed control while maintaining the integrity of the local environment. We use as little chemical as possible to avoid non-target damage, and all our staff are conscious of protecting the ecological value of each work site. We employ a range of weed control techniques; from cut and paste to using a 500L motorised spray tank.
Do you have weeds on your property? Keystone Ecology can control and eradicate a wide range of species, including the following . . .
- Boneseed (Chrysanthemoides monilifera)
- Broom (Cytisus scoparius, Cytisus multiflorus, Teline monspessulana)
- Gorse (Ulex europaeus)
- Nodding thistle (Carduus nutans)
- Variegated thistle (Silybum marianum)
- Old man’s beard (Clematis vitalba)
- Ragwort (Senecio jacobaea)
- Velvetleaf (Abutilon theophrasti)
- Wildling conifers (Pinus contorta)
New Zealand has a staggering 2,200 exotic plant species that have now become naturalised (common in our environment) throughout the country (Allen & Lee 2006). Because of these foreign plants we are losing our native biodiversity and continue to risk some species going extinct. At Keystone Ecology we are dedicated to stopping this process in its tracks and restoring our native and endemic flora.
