Plant identification and info


INaturalist offers both a phone and browser app. The phone app allows you to take a photo then refer it for suggested identification.
INaturalist also allows expert to check photos submitted by citizen scientists and to confirm the identification (if the photo is good enough).

Nature Space

Nature Space is a site that was being developed by Auckland Council in conjunction with other organisations:

It is intended to provide a resource kit for bush restoration and to assist in monitoring the health of our native flora. 

It is arguably as at 2018 the best place to find what volunteer groups exist.

Botannical Society

The Auckland Botannical Society has visited Le Roys Bush a number of time over the years.
Their 2002 visit is covered in this report.

NZ Plant Conservation Network

For help in identifying native plants and other weeds, we recommend the  New Zealand Plant Conservation Network web site which provides a comprehensive list to help identify native plants and invasive weeds.

Landcare Research

There is a very structured search tool at
which allows you to search by characteristics (many of them are rather specialist for the average lay person) and then links to the Landcare Research Databases of plants at or

Links about plant identification and management

For more information on plant identification and weed control, see our page What's Good. What's Not. (one day we'll need to integrate these sites!)

A summary list of sites about plants found in NZ - good ones and invasive: - very comprehensive coverage of good plants and weeds 
And the mobile site which links to the weed key of about 518 weeds: --  not many plants an interesting collation of info about the plants - eg  Participating institutions are Landcare Research, Te Papa, and NIWA of course for marine plants - the encyclopaedia of NZ section on bush

And about weeds specifically: - gives details of how to control weeds with or without agrichemicals
They also have a facebook page

There is also the NZ Pest Plant Accord - which is of limited use - mainly intended for commercial companies - but unfortunately once a weed is no longer likely to be sold, they remove it from the list.

And there is a Global Invasive Species Database eg for Acanthus mollis at

And there's also the local government sites such as: - the Northland Regional Council site for comparison

Some commercial sites are helpful; eg  Oratia Native Plant Nursery website and

Also please see the LRB "poster" document attached below for a list of plants (natives and weeds) found in and around the Le Roys Bush wetlands. 

This poster was adapted to provide information for the BNZ volunteers in September 2013.
