How you can help

* Read our latest coronavirus (COVID-19) update *

There are a range of ways that you can help conserve our freshwater environment and keep it clear of Invasive Non-Native Species (INNS) for the benefit of our native wildlife.

You can get hands-on with some invasive plant removal, keep an eye on your local river and report any sightings of invasive species or make an individual commitment to undertake more biosecurity actions.

Get involved and volunteer!

We'd love to hear from anyone who is interesting in volunteering with the Scottish Invasive Species Initiative, whether you want to come along for just a day out in the fresh air, or become a dedicated Invasive Species crusader! 

Read on for the Who? What? Where? When? of volunteering.

Our plant control work is seasonal, we treat invasive plant during the growing season, typically April - October. 

Our mink control project runs all year round. 


volunteer group


Invasive species are a great threat to the native wildlife of Scotland. Our project is only funded for five years, so to be successful and create a long-term sustainable solution to controlling invasive species we need your help.

By providing free training, supporting and equipping volunteers we aim to embed invasive species control at a local level, within communities and supported by the local Fishery Trusts, so there is a long-term commitment to continuing the good work after the Scottish Invasive Species Initiative finishes.

Student placement

Elise found out about volunteering through her university (UHI) and decided to do her 4th year placement with the SISI project. She started with the project in July working 3 days a week with one of the SISI project officers and continued right through to October. She has helped with cutting giant hogweed flowers, pulling Himalayan balsam and stem injecting Japanese knotweed.

She said "I've really enjoyed it, it's been a great way to spend my summer, I've met lots of new people and had a great banter and also developed my skills for future careers. Before I felt like a sham, studying Environmental Science but I didn't have any experience or stories to tell, but now I do have stories and experiences. It's been really helpful for me doing this work, now I have practical experience. I'm going to do more volunteering."



Calum looks after the Meikleour Fishings on the River Tay. He's been a dedicated mink volunteer for years, monitoring his patch and successfully catching several mink. 

Calum said "Mink have a devastating impact on our local wildlife - I've witnessed it with my own eyes; I once watched a mink raiding a kingfisher nest, it came back again and again, until it had taken every chick out of that nest, it was total devastation."

Angus Canoe Club

Film stars

Three fantastic volunteers from the Angus Canoe club volunteered their services to help SISI make a film about biosecurity.  They were set off to paddle down the river bedecked with helmet cams and kayak mounted 360o cameras to capture the essence of enjoying the river - something not everyone gets to experience from that angle - and then showed us all the biosecurity practices they do on pulling out of the river to clean out their kayaks and wash down their gear, so they don't run the risk of moving invasive species from one river to another. 

Tom said "We were happy to lend a hand when we were asked if we could feature in the SISI film, cleaning your gear after coming out of the river is really important and something we were happy to help promote."
