Be Plant Wise campaign relaunch
The Be Plant Wise campaign was relaunched in September as part of UK Plant Health Week. The updated campaign asks asking retailers to take a pledge to support the campaign and order a free Be Plant Wise pack, and gardeners and pond owners follow three simple tips to help prevent the spread of invasive plants:
- Know what you grow – Choose the right plants for your garden, pond and water features.
- Stop the spread – Keep your plants in your garden - don’t plant them, or allow them to grow, in the wild.
- Compost with care - Dispose of your unwanted plants, roots, weeds, seeds, and seed heads responsibly.
Invasive Species Week 2021
Save the date! Invasive Species Week 2021 will be held during the week beginning 24th May 2021. More information to follow.

Updates from non-native species projects
The Angling Trust has produced a video (external link) from a recent launch of the Thames Floating Pennywort Pilot project, which took place on the River Kennet in September.
The project involves environment groups and government agencies working together to help halt the spread of floating pennywort, a highly invasive non-native plant that is choking rivers and lakes across Britain. This video (external link) looks at the work being carried out on the River Kennet and tributaries involving Reading and District Angling Association and other organisations.
Scottish Invasive Species Initiative – Coronavirus impacts and insights
Vicky Hilton, Scottish Invasive Species Initiative
At the Scottish Invasive Species Initiative, the spring Coronavirus (COVID-19) lockdown saw us faced with the prospect of invasive species fighting back whilst we stayed at home. For us, as for everyone else, there were more important public health matters to be tackled as the COVID-19 pandemic did its worst.
March saw us contacting our 270 mink volunteers with instructions to suspend monitoring and trapping activity. We pessimistically anticipated the backwards step this would bring - shutting down our surveillance and trapping network after 2½ years of hard work establishing it. We underestimated the tenacity of our volunteers - the response from many was a determination to continue; “We’ll use our daily exercise to check our raft” was the frequent reply. While raft and trap numbers reduced from 578 to 319 units, over half the network was kept up and running by volunteers through lockdown. By July, when lockdown restrictions had eased, the network had been restored to near pre-lockdown levels and trapping effort returned to that needed to tackle the autumn dispersal period when young mink move to new territories for next year’s breeding season.
We used staff home working time during lockdown to take our education pack – Alien Detectives (external link) - to another level. With a sudden demand for home schooling materials and talk of future blended education with outdoor learning encouraged, we used desk time to widen the scope of the Alien Detectives resources making them suitable for use by families and home-learners as well as in schools.
Emerging from lockdown we adapted our plant control strategy. Staff and contractors were unable to start work until June – and, of course, by then giant hogweed plants were indeed giant and coming into flower. Our window for chemical control was closing quickly. We prioritised our most important hogweed sites for action – where possible we treated chemically but elsewhere, we cut flowering heads to prevent seeding and spread. Himalayan balsam pulling, normally run as summer group activities, was curtailed - group work was not an option this year. By autumn when we shift to Japanese knotweed treatment, things were beginning to get back on track and small numbers of volunteers helped with stem injection. We adjusted our procedures to keep our team and volunteers safe but we were operating back at something akin to ‘normal’.
So, although our activities were and are constrained, we have continued work with volunteers on mink and plant control programmes and, together, keep those invasive species in check. A surprising bonus this year was the unique and early insight gained as to what future invasive species control post-Scottish Invasive Species Initiative might look like.
Our work implementing a community-based approach to invasive species management is geared towards creating a sustainable legacy to the Initiative – building community capacity to continue control after the project has ended. The COVID lockdown suddenly put this to the test – what would happen to invasive species control when we weren’t around? We witnessed volunteers maintaining mink monitoring and control, farmers and land managers using their staff (trained by us) to continue Giant hogweed treatment when we couldn’t, and local people heading out on their own to pull balsam on sites we’d worked on together previously.
We acknowledge this was a snapshot taken in exceptional circumstances and we can’t say whether such enthusiasm would stand the test of time. However, the observations from 2020 suggest our strategy is indeed the right one. The impression we have is that work investing in communities, training volunteers and engaging at a local level are working and are creating a resilient, skilled, enthusiastic network of volunteers - willing to carry on the battle against invasive species. We look forward to building on these foundations in 2021.

Recording non-native species: water primrose
Trevor Renals, Senior Technical Advisor, Invasive Species, Environment Agency
Water primrose Ludwigia grandiflora is an ornamental perennial plant native to South and Central America, associated with wetlands and marginal zones of watercourses, ditches, ponds and lakes. The plant has been introduced into GB through the ornamental aquatic plant trade. It primarily spreads by vegetative fragments and forms dense carpets of growth that exclude native biodiversity, increases flood risk and siltation and degrades amenity.
Since 2009, the Environment Agency has been coordinating the eradication of water primrose in GB. During that time, a further 29 sites have been added to the 14 initially confirmed in 2009. Of those sites, 16 are believed to have been eradicated over the 11 year period. Water primrose is proving hard to completely kill, but the programme has successfully reduced the biomass of known sites to a fraction of the original infestation. By the end of 2019, the combined total area for all known water primrose in GB was less than 100m2, but this has increased during the pandemic restrictions, despite the valiant efforts of site managers.
If you suspect that you may have seen water primrose, check the identification with the ID sheet (PDF) and report it (external link).
Tackling Invasive Non-Native Species in the UK Overseas Territories (The OT Biosecurity Project)
The UK Overseas Territories (OTs) encompass some of the greatest biodiversity in the world, accounting for 94% of the UK’s endemic biosecurity. As small islands they are particularly vulnerable to the impact of invasive non-native species - the greatest threat to island biodiversity, and a risk to food security and sustainable development. A 3.5 year NNSS led project, funded by the FCO’s CSSF fund (external link), was carried out between 2016 and 2020 to improve the biosecurity of the UK Overseas Territories (OTs) against invasive non-native species. Total project funding was £1.26 m, less than £20,000 per territory per year.
At the end of the project, the OTs have substantially strengthened their protection against the threat of invasive non-native species as a result of project activities. The project involved 343 people within the OTs, 9 UK government and part-government bodies, and more than 150 external experts from 54 entities in the UK, Europe and USA. In addition, the project mobilised over £1m in co-finance, in effect almost doubling the project budget. The project continues with reduced funding, principally to provide technical support to the OTs on request.
EMFF Biosecurity Planning for Pen Llŷn a'r Sarnau Special Area of Conservation
Chloe Powell Jennings, Natural Resources Wales
Chloe Powell Jennings (Natural Resources Wales) is working on a project which involves working with stakeholders to create a marine biosecurity plan for the Pen Llŷn a'r Sarnau Special Area of Conservation (PLAS SAC). The project is funded by the European Maritime and Fisheries Fund and will run to June 2022.
The project has so far been gathering evidence to underpin biosecurity planning and two reports have recently been published as part of the project (pathways assessment and INNS impacts on MPA features, fisheries and aquaculture). Chloe is currently working with the Welsh Fishermens Association, the PLAS SAC officer and other stakeholders to look at what biosecurity actions could be feasible in the area to inform the species action plans and pathway action plans. Chloe has also been working on distribution maps, fact sheets for relevant species and stakeholder identification training (online!)
The next stage of the project is to continue using local knowledge gained from stakeholder engagement (questionnaires, online meetings, etc.) to continue working on the species and pathway action plans and possibly hold an online workshop early in the New Year (if feedback is that one would be useful). The project will also involve further monitoring, management and awareness raising actions including a contingency plan exercise, producing biosecurity videos, etc. The final phase of the project will be to implement, embed and monitor the biosecurity plan.
