My parents bought the land in 2000 and started the fencing of waterways in about 2003. I am noticing that the regeneration is just starting to take off. There aren't many medium sized plants but there are literally thousands of small plants and new seedlings at the back of their property. Just before we moved here in 2008 I started trapping possums and planting the fenced off areas.
We've planted around 3000 trees and hope to do another 3000 in the next two years. We used a number of different species found locally with the majority of what we planted being manuka. It supports both groups of mycrohizzal fungi, provides a lot of mulch and is relatively cheap, making it the perfect choice for native regeneration. We've noticed a substantial increase in native bird life since we started trapping.
We don't use and fertiliser on the land as it is very lightly stocked. Dad used lime and liquid fertiliser on his dairy farm in Kerikeri. His stocking rate was also on the low side. Their production was still high however due to a good breeding programme which resulted in record sale prices when their herd was sold. The main barrier here has just been time. Being a landscaper has helped. The Kaipara council also refunded the money for the fences and these areas have been covenanted.
