Oaks New Zealand
New Zealand has about 140 of the ~600 species of oaks found worldwide. Some species are commonly planted as farm and amenity trees. Many others are represented in small numbers in botanic gardens, arboretums and a few private collections. It is very difficult and expensive to import new oak genetics into New Zealand. Acorns must be imported through post-entry quarantine and spend up to 2 years there before they are given biosecurity clearance.
Therefore a first priority for Oaks New Zealand is to conserve and fully utilise the genetic resources of oak trees already in New Zealand.
Oaks New Zealand is currently developing the following pilot projects:
- Battle Hill Farm Forest Park, Pauatahanui - planting programme to establish a range of different species and seed orchards over 5 years.
- Longitudinal measurement study of Mexican oak species on dry sites: Guthrie Smith arboretum, Hawkes Bay & Penrith Park, Marlborough.
- Red oak planting trials - East Coast, Hawkes Bay, Wairarapa.
- Selections of precious species with edible, large acorns for food (human nutrition / paleodiet).
