For most ecological restoration projects, encouraging the correct vegetation is normally the cornerstone of the work. In more established areas, monitoring can include noting the type and health of the species that occur in each vegetation tier (understorey/canopy etc) and recording the density of seedlings and saplings on the ground.
There are many methods, below are a couple:
FORMAK - kit for monitoring native forest ecosystems.
This system encourages the recording of information in a quantitative way, and the field kit and guides help you to collect information in a simple yet objective way. On their website you can view the FORMAK manual, store your data and purchases equipment.
Provides a basic framework and secure data storage for recording plant growth, performance, and phenology, and wildlife status.
When plantings have been done in an area, monitoring their survival rates is very important. Depending on the outcomes of this, your group could adapt the methods used or plant species which have higher survival rates in certain habitats. Simply recording the number of plants which survive using a 6 monthly cycle will achieve this and will alert you to trends you may not otherwise notice.

Plant information and ID
New Zealand plant conservation network website is a place that can used to find information about plants found in New Zealand, both native and exotic. You can also upload photos to forum for help to identify plants you have seen.
