RECOGNISE Visit www.nonnativespecies.org for help with identifying invasive plants and for useful advice and guidance.
Check your garden and land for signs of any invasive non-native plants.
REACTControl any invasives found on your land to reduce the risk of spread.
Training and Personal Protective Equipment is required for spraying.
Approved weed killers can be used to treat invasive species near a watercourse if you follow SEPA’s General Binding Rules – Number 23.
Be careful not to include any invasive plants in your compost.
Check your boots, pets and equipment for seeds and clean where necessary.
REPORTReport any invasive plants you see to the North East Scotland Biological Records Centre www.nesbrec.org.uk with details of what you have seen and where they are located.
Gardeners beware! Some garden centres still sell invasive plants. Learn about which ones to avoid.
Businesses and public bodies have similar responsibilities for land under their management.
Landowners and farmers are responsible for controlling invasive species on their land, and it is good practice to prevent such species spreading into neighbouring land.
All of us! It is important to Recognise, Report and React to Invasive plants. Seek advice and follow good practice, see:
• Scottish Government Non-Native Species Code of Practice
• Horticultural Code of Practice.
Protecting our native plants, wildlife, rivers and us!
Invasive Non-Native PlantsNon-native species are animals or plants that have been introduced (deliberately or accidentally) by humans, into an area in which they do not naturally occur. Some are termed invasive as they can spread, causing damage to the environment, the economy, our
health and access.
What is the law? It is illegal to plant or otherwise cause a plant to grow in the wild at a place outwith its native range. The aim of the legislation is to prevent the spread of invasive non-native plants from cultivated areas, such as gardens. There is no legal requirement to control invasive species that are already established in the wild, however SNH can enforce action on landowners failing to act as part of a coordinated eradication program.

The NE Non-Native Invasive Species (NENNIS) Project is helping to locate and control invasive plants. With the help of local volunteers, NENNIS aims to enhance the riverbanks and protect native wildlife.
Why are invasive plants a problem? » Invasive plants are quick to spread and dominate.
They out-compete native plants, stealing their light, space and nutrients. This threatens native habitats and wildlife.
» Invasive plants dominate large areas in summer but die back over winter, exposing bare ground to erosion. This promotes water pollution and increases flood risk.
» Access to the river for recreation is restricted.
» Giant Hogweed can burn eyes and skin, resulting in painful blisters and scarring for you or your pets.
» Japanese Knotweed can rip through tarmac and concrete, damaging property and infrastructure.
» Japanese Knotweed and Giant Hogweed require special waste handling licences for disposal.
» Control is costly and requires full knowledge of control methods and regulations.

Giant Hogweed (Heracleum mantegazzianum)Native to: SW Russia and Georgia
Why is this dangerous? Not only does it shade out the light to native plants, the sap can badly burn your skin and that of your pets, resulting in painful blisters when exposed to sunlight.
Height: Up to 4 metres
Easily confused with: Cow Parsley and Common Hogweed.
Himalayan Balsam (Impatiens glandulifera)Native to: West and Central Himalayas
What’s the problem, it’s beautiful?Bumblebees are attracted to the nectar, resulting in less pollination of native species. When it dies back in winter, the bare banks are left vulnerable to erosion.
Height: Up to 1-2 metres
Easily confused with: Orange Balsam.
Japanese Knotweed (Fallopia japonica)Native to: Japan, Taiwan, Northern China
No mortgage for you! Japanese Knotweed can grow through tarmac and cause extensive damage to properties. It devastates habitats for local wildlife and leaves riverbanks more prone to flooding.
Height: Up to 3 metres
Easily confused with: Giant and Hybrid Knotweed.
Pirri Pirri Bur(Acaena novae-zelandiae)Native to: SE Australia and New Zealand
Tagging along for the ride! Originally introduced as a contaminant on wool, the pirri pirri bur forms dense vegetation mats which prevent native plants from establishing. Found near sand dunes or on sandy soils. Can easily be spread by dogs and humans by getting caught on fur or clothing.
Height: 2-15cm Dwarf Shrub
