Help monitor and protect our lakes and ponds
We want everyone to become interested in the aquatic world, and have the skills to observe changes in water quality by identifying key plants and animals.
Protecting a nature oasis
Ponds and pools are often found in shared spaces such as parks. They can be oases of biodiversity in otherwise ecologically poor areas and are important for human and environmental wellbeing.
However, they are often struggling with problems such as water pollution and nutrient enrichment, and may also be poorly managed.
