Scotland water resilience given boost with 10-year plan

A scheme to protect future water supplies and create one of the biggest new woodlands in Europe has taken a major step forward at an iconic Scottish loch.
A ten-year plan for the land at Loch Katrine includes the restoration and maintenance of several hundred hectares of peatland across the site as well as the creation of over 4,600 hectares of native woodland, largely through rewilding and natural regeneration.
It is anticipated that delivering these actions will see a 40% increase in the status of biodiversity across the site, as well as capturing up to 1 million tonnes of carbon over 60 years.
This is key to helping protect the quality and resilience of the water supply at the loch in the face of more extreme rainfall patterns due to a changing climate. Restoring natural woodland and encouraging healthy, functioning, peatland and moorland will make the landscape more resilient, helping to stabilise soils to hold more water and slow the runoff from the land.
This results in less organic matter being washed into the loch and into the water treatment works and ensures the water can continue to be treated to the high standards Scottish Water utility customers expect.
The freshwater Loch Katrine is almost 13km long and supplies water to 1.3 million people in the Greater Glasgow area via largely Victorian-built infrastructure and is surrounded by 9,500 hectares of land which is occupied and managed by Forestry and Land Scotland (FLS), located in the heart of the Loch Lomond and Trossachs National Park (LLTNP).
Dr Mark Williams, Scottish Water’s head of sustainability and climate change, said, “Loch Katrine is a hugely significant site in terms of Scotland’s natural environment, as well as being the basis of an essential service for around a quarter of Scotland’s population.
“It has nationally important peatland, moorland, and woodland habitats, which offer many recreational opportunities for visitors and residents alike but which are also vitally important in our work to mitigate the impact of the climate crisis."
Long-term collaboration
The 10-year Land Management Plan (LMP) for Scottish Water’s Loch Katrine estate is developed in partnership with long-term tenant Forestry and Land Scotland (FLS) and has been approved by Scottish Forestry.
"By taking a whole-catchment approach, this 10-year plan sets out a long-term vision which will help secure the resilience and quality of Loch Katrine as a vital water supply into the 22nd century..."
Williams said, “The energy needed to provide essential water and wastewater services makes Scottish Water one of the largest single users of electricity in the country, and whilst we are working hard to eliminate emissions across the entirety of our assets, we must also ensure that the woodland, peatland, and natural habitats across our landholdings are thriving, able to lock up carbon and support the journey to net zero emissions.
“By taking a whole-catchment approach, this 10-year plan sets out a long-term vision which will help secure the resilience and quality of Loch Katrine as a vital water supply into the 22nd Century while also supporting nature, tourism, and the rural economy.”
The site also makes an active contribution to the Great Trossachs Forest, an initiative driven by FLS, Woodland Trust Scotland, Loch Lomond and the Trossachs National Park Authority, and the Royal Society for the Protection of Birds (RSPB) that will see a rich and diverse mosaic of wildlife habitats stretching 16,500 hectares from Callander in the east to the shores of Loch Lomond in the west.
Carol McGinnes, central region manager for FLS, said, “It has taken a lot of hard work in this collaborative effort to get the project to this stage. We can now look forward to on-the-ground delivery and making changes that will further enhance a very special landscape.”

Diverse nature restoration
Simon Jones, director of environment and visitor services at Loch Lomond and the Trossachs National Park Authority said, “This signals another big step towards the National Park Authority’s goal to reverse the decline in nature by 2030 and see widespread restoration of nature by 2040. The water, peatland, and woodland within the Park are undoubtedly our greatest allies in tackling the twin crises of nature loss and the climate emergency.
“As well as our wildlife, the wider natural environment helps to deliver many essential aspects of our lives, from the nutritional value and availability of our food, and the health benefits of good air quality, to the livelihoods of those connected to it. Only through partnership working like this will we achieve the scale of change required to ensure a sustainable future for the National Park.”
Future woodland creation at Loch Katrine will look at encouraging native woodlands, which currently exist at lower levels in the catchment, to expand to sites at a higher elevation therefore linking woodland from the shores of the loch up into the hills. Work will also focus on restoring peatland across the site, rewetting, reprofiling, and encouraging sphagnum moss to proliferate ensuring it can once again start to retain water and slow surface water run-off into the loch, as well as act as a carbon sink.
The project will see a variety of habitats of healthy peatland, moorland, and woodland benefit the diversity of wildlife in the area including badgers, bats, a huge variety of birds, and rare species such as the Pearl Bordered Fritillary butterfly.
Cameron Maxwell, Perth & Argyll conservator with Scottish Forestry, said, “We were delighted to approve this ambitious new native woodland creation proposal on the land around Loch Katrine, continuing the expansion of the Great Trossachs Forest National Nature Reserve.”
