About Us

About Us

The Scottish Invasive Species Initiative (SISI) is a 4-year partnership project which aims to work with local organisations and volunteers to control invasive non-native species along riversides in Northern Scotland, for the benefit of our native wildlife and communities. 

SISI is led by Scottish Natural Heritage (SNH) and is funded by the Heritage Lottery Fund, SNH and by in-kind support from project partners and volunteers.

Our iconic Scottish freshwater rivers and lochs are at the heart of our environment and they play a key role in supporting much of Scotland’s wildlife, support a range of economic activities and have a high social and recreational value. Invasive non-native species (INNS) are having a significant negative impact on our freshwater and riparian (riverside) environments, being responsible for the decline of native species and causing effects like bank erosion. We want to halt and control the spread of invasive species, undertake habitat restoration and encourage the return of our native wildlife.

Our project staff will work with the ten Fisheries Trusts/Boards who look after the rivers from the Tay in the south to the remote catchments of North West Sutherland, to recruit and train volunteers and work with local groups to enable control of invasive species at a local level, embedded in the community. We are funded for 4 years, until Oct 2021, after which time our aspiration is that local community control of invasives will continue, making this a sustainable long-term solution to invasive species control. 

Everyone can help halt the spread of invasive non-native species, whether by getting directly involved in their control, practising better biosecurity to limit their spread or by simply being more aware and reporting invasive sightings. We want to raise awareness of the problems invasives cause and engage the public in being part of the solutions.

This is an ambitious project, aiming to create a sense of cohesion between partners, volunteers and communities and working at a large-scale across a third of Scotland to ensure co-ordinated INNS control. Read more about our partners and funders.

Our Project Area

The Scottish Invasive Species Initiative project area is defined by the boundaries of the fishery trusts and boards that we are working in partnership with. It stretches from the Perth area in the south, covers the whole of North East Scotland and across to the west coast (Kyle of Lochalsh to the south) and northwards to Durness, in North West Sutherland. The area encompasses a variety of communities, geography and land uses. It also includes a number of sites designated for wildlife / conservation value and the SISI project activities will help protect habitats and species on 22 of these sites from invasive non-native species. 

In total we cover an area of 29,500km2  - over a third of Scotland (and an area larger than the country of Wales!).

Our Activity Plan

Giant hogweed plant

Invasive Non-Native Plant Control Project

We are targetting several key invasive non-native plants across the project area - the worst offenders in creating problems in our environment. As well as our own staff and contractors removing these, we will recruit, train, equip and support a network of volunteers across the partnership area. We aim to have all our target areas in a minimal maintenance state within the duration of the project.  

Our key invasive plant control target plant species across the project area are; Giant hogweed, Japanese knotweed, Himalayan balsam

American Mink

American Mink Control Project

The invasive American mink is well-known to be responsible for the decimation of native wildlife, particularly the water vole. Building on the work of previous mink control projects, and in partnership with the University of Aberdeen, we will undertake a programme of monitoring and trapping for removal of mink, with the help of a network of volunteers. We aim to have breeding mink reduced to minimal levels (less than 10% of original detection rates) and we aim to see recovery of native mink prey species; water vole and moor hen.

Spreading the word

We will raise awareness about invasive non-native species, and educate people about their impacts, how they can practice good biosecurity and how to record sightings.  We will engage people in discovering about the importance of the river environment and its native wildlife and deliver various education programmes to schools ensuring we are inspiring and educating the next generation to value our iconic species and habitats.

Creating a volunteer community

Central to our approach is the establishment of a volunteer network that will be passionate about our iconic freshwater habitats and species and will continue to control invasive species beyond the end of the SISI project.  We know from previous projects that partnership and volunteer-based invasive control at large geographical scales can be successful - we also know that control at this scale is challenging and takes hard work and investment in people to be sustainable.

Keep it Clean! Promoting biosecurity

A key part of controlling invasive species in Scotland is preventing their spread into new areas.  This can happen naturally by seed dispersal, but often it is due to people unwittingly carrying invasive species as hitchhikers on their canoes, fishing gear or walking boots. As part of our project we will highlight the importance of practising good biosecurity measures so we can stop the spread of invasive species.
