During this period we shall concentrate only on queries that have been requested as urgent, and that these will take longer to reply than is typical. We apologise for the inconvenience and thank you for your patience.

How to collect and prepare specimens

To determine the best way to prepare your specimens for identification please see our printable booklet on collecting plants (PDF, 216 KB).

The identification of plant specimens can be difficult and at times requires a considerable amount of time and effort. In order to give you accurate identifications we require well-collected specimens with adequate accompanying information.

Important information

Collecting permissions

Before you collect, please ensure you have permission. An appropriate licence is required prior to collecting plant specimens from land managed by National Parks and State Forests in New South Wales. Permission should always be sought from the landowner and/or manager when collecting specimens on private land.

The collection of species listed under the Biodiversity Conservation Act 2016 requires a licence to pick or harm a threatened species or ecological community. Please provide permit/licence details with your plant specimens.

What happens after identification?

The specimens we receive and retain through the Botanical Identification Service make a significant contribution to our knowledge and understanding of the New South Wales flora. They become a permanent record in the herbarium providing invaluable data on the distribution and ecology of our flora.

This data contributes to resources such as NSW Flora Online (PlantNET), Australasian Virtual Herbarium and Atlas of Living Australia.

  • general gardening advice
