Everyone can provide useful biological records of non-native species, and with the development of online recording sites and smartphone apps it is now easier than ever. Non-native species records help us to understand how many of these species are present in Britain, and the rate at which they are spreading.

Species to record

There are a range of recording schemes available covering a variety of non-native species, but it is particularly important to record alert species. Early identification of these could help to prevent future problems from developing.

Keep up to date with new alert species here.

Current alerts include:

Where to send your records

We recommend submitting your records online, or through a smartphone application as these are fast and efficient. See below for a number of recommended schemes.

Online recording schemes


Use for: General use

Records of any non-native species can be uploaded to iRecord. Register for a free account which will allow you to view and manage all of the records you have submitted. You can also submit records of native species.

Recording Invasive Species Counts (RISC)

The RISC project brings together recording schemes run by a range of organisations. Use it to submit records of 21 invasive non-native animals and plants.

Smartphone Apps

All apps currently available for iPhone and Android.

Asian Hornet Watch

Use for:
potential Asian hornet sightings

Asian Hornet Watch was developed by the Centre for Ecology and Hydrology. Use it to help monitor for the alert species Asian hornet, an invasive predator of honey bees and other insects. Asian hornet was first spotted in the UK in September 2016 and a nest quickly removed, but there is a chance this species could reappear this spring. Use Asian Hornet Watch to browse photo galleries and key identification information for this and other similar species, and submit possible records quickly to help prevent it from becoming established.

To download the app, search Asian Hornet Watch on Google Play or the App Store.

If you don't have a smartphone you can submit records online or by email to (with a photo if possible).
Conker tree science leaf watch

Use for: monitoring conker tree health

Leaf Watch was developed by the Universities of Bristol and Hull. Use it to help scientists monitor the spread of an invasive leaf mining moth causing harm to Conker trees.
Tree Alert

Use for: monitoring tree health

Britain's trees are under unprecedented threat from new pests and diseases. Help the Forestry Commission to identify trees that might have problems - particularly ash, oak, horse chestnut, pine or spruce trees - so they can find out more or take appropriate action.

Looking to get more involved in identifying and recording wildlife?

If you get involved in the recording schemes above and enjoy looking for non-native species, you may become interested in recording other wildlife. If so, take a look at iSpot, a website aimed at helping anyone identify anything in nature.

Once registered, you can add an observation to the website, suggest an identification yourself, or see if anyone else can identify it for you. Take a look and get more involved in recording wildlife today!
