About the Ecological Traits of New Zealand Flora


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.

Ecological traits for individual species are organised into six groups of attributes: Status in New Zealand, Distribution, Morphology, Reproduction, Flower and Fruit, Wetland and miscellaneous.  Please see below for a brief explanation of each group.  A description of each trait recorded within these groups can be found in the Glossary.


Trait categories covered by this database:



Status in NZ
Whether the species is native etc. to New Zealand, its history of introduction where applicable in New Zealand and overseas.  Whether the species or its relatives are weeds.  Also whether the climate in its home range and New Zealand are similar.

Distribution
Its distribution within New Zealand, the communities it grows in, and its global distribution.

Morphology
The species' life form, height, longevity, morphological features, presence of vegetative reproduction, and leaf parameters.

Reproduction
The species reproductive system, time until reproduction, resprouting ability, seed output, seed size, seed dispersal method(s).

Flower and Fruit
Time of flowering and fruiting and size and properties of flowers and fruit.

Other/Wetland
Others: whether poisonous, palatable, or nitrogen fixing etc.  Wetland: descriptors specific to wetland species covering morphology and habitat preferences.
