The New Forest is not only one of the most Important Freshwater Landscapes in the UK, with a huge array of rare species and incredible biodiversity, it’s also one of the few remaining clean water hotspots. 💧🙌🏻
Our WaterBlitz surveys from 2022/23 tested 828 freshwater locations for nitrates and phosphates. The results showed that an impressive 81% of sites contained clean, unpolluted water. Most clean waterbodies were found within the core of the National Park, where pollution input from agriculture and development is minimal.
By comparison, a similar survey in another catchment of the same size found that just 28% of sites contained clean, unpolluted water. Sadly, this figure more accurately reflects the reality of freshwater quality across the UK.
We also found that clean water is more commonly associated with smaller waterbodies such as ponds, with 79% of small waterbodies holding clean water compared to 53% of larger waterbodies.
Smaller waterbodies are often isolated away from pollution inputs, and as such can act as powerful clean water refuges for wildlife. However, our running water network – which is impacted by pollution from multiple sources across the catchment – is showing worrying declines in water quality. Our 2022/23 WaterBlitz data shows a decline in water quality in 6% of the waterbodies we retested from our initial 2016 WaterBlitz. Whilst these declines are present across all waterbodies, they are most prevalent in the running water network.
We’re lucky to have an abundance of small waterbodies within the New Forest – over 1000 mapped ponds alongside countless headwater streams, trackway pools and ditches. The clean water provided by these small but mighty wildlife refuges, paired with the longstanding tradition of livestock grazing, creates the perfect conditions for wildlife to thrive. Despite this, the Forest is still subject to the same pressures as other landscapes – and the impact is starting to show.
Protecting places like the New Forest shows what’s possible, and highlights why bringing back clean water must be a priority everywhere. With freshwater species populations declining at a rate 4 to 6 times greater than their marine and terrestrial counterparts, this is more important now than ever. 🩵🙌🏻
