Enrichment planting for established Greendots
A healthy native forest is made of several layers, ranging from the leaf litter on the forest floor to mature forest giants such as Totara and Kahikatea.
When planting Greendots, we plant the hardy nursery species of the forest that can establish with minimal shelter from extreme winds and frost. For the first two to three years, weed control is required between the native plants to remove competition for moisture, light and nutrients, after that time the taller species of a Greendot will form a canopy which reduces light to suppress weed growth and creates a sheltered environment below.
Restoration is a long term process and the aim is that a Greendot will eventually become self-sustaining with no human intervention required. Ideally once a Greendot has canopy closure, natural regeneration and introduction of other forest layers will begin to occur, with seed dispersal by birds being an important component. For a variety of reasons, including a lack of nearby seed sources or bird presence, this may not always happen, and this is especially likely in parts of Canterbury.
Enrichment planting may be required to recreate the natural composition of the forest. By actively planting those sensitive species that will make up secondary forest layers we can create a better representation of a natural forest and more diverse biodiversity.
Enrichment plant species will differ depending on each site but may include tender species such as kawa kawa, ferns, mahoe and native mistletoe. Te Ara Kākāriki invite Greendot owners who have sites that have formed a canopy (5-10 years old) to contact us if they are interested in enrichment planting at their Greendot.
