This database began life as a repository of information for projects on New Zealand weeds, and wetland plants. It holds a list of all native and all naturalised higher plant species. Most effort to date has been on entering data on the naturalised flora and this information is updated from time to time. The ecological trait data covers world and local distributional data, morphological, reproduction, and other attributes that influence species' environmental responses, and interactions with other plants and animals. Attributes relevant to weed management such as response to damage, reproduction capacity, seed longevity, and weed status elsewhere are included. The database does not capture information on weed control methods. Data are derived from publications and databases on the the New Zealand Floras and many other publications.
