Invasive Species Eradication & Pond Renovation
Restoring balance and safety to a rock-face wildlife habitat
Location: North Somerset
Project Scale: Challenging rock-face residential pond
Core Expertise: Invasive Species Management (Floating Pennywort), Ecological Rescue, Steep-Incline Logistics
Our Approach: Precision Rescue & Ecological Reconstruction
This project required a meticulous, multi-stage restoration strategy to protect the existing ecosystem while completely altering the pond's infrastructure.
1. Wildlife Rescue
Before any structural work could begin, we carefully netted and transferred all aquatic residents to a safe, temporary holding habitat. This included salvaging Dragonfly Nymphs, Tadpoles, and immature Smooth Newts.
2. Biosecurity & Plant Bio-Decontamination
To save the mature, healthy native plants, including Yellow Flag Iris, Marsh Marigold, and White Water-Lily, we painstakingly cleared and root-washed their systems to ensure not a single fragment of Pennywort remained. The invasive Pennywort was safely bagged and transported to a secure waste facility to prevent any risk of cross-contamination into the Somerset countryside.
3. Structural Re-Engineering
Working on a steep slope, we transported tons of pond compost, sand, and locally sourced stone to rebuild the habitat:
Safer Perimeters: We softened the steep banks, creating shallow, stepped margins that allow mammals and amphibians to enter and exit safely.
Hidden Longevity: A new professional liner was installed and completely concealed beneath local stone to protect it from UV damage and create a natural aesthetic.
The Challenge: Overcoming Invasive Growth & Dangerous Topography
The clients, Mr & Mrs Wilson, inherited a wildlife pond with severe structural and ecological issues. Built directly into a steep rock face, the pond had been completely engulfed by floating pennywort (Hydrocotyle ranunculoides) a non-native, highly invasive species that chokes out light and oxygen.
Previous removal attempts had failed. Furthermore, the original liner was exposed and degrading, and the pond’s perimeter banks were dangerously steep, creating a drowning hazard for terrestrial wildlife trying to access the water.
The Goal: To completely eradicate the invasive Pennywort, salvage the native flora, rescue the existing wildlife, and re-engineer the pond with hidden liners and safe, shallow margins—all on a highly challenging, steep incline.
The Results: A Rebalanced, Thriving Wetland Feature
With the Pennywort eradicated and the new internal stone habitats established, the pond has been transformed from an unappealing hazard into a high-functioning ecosystem. The returned wildlife now enjoys a clean, oxygen-rich environment with ample cover.
| Feature | Observations & Species Recorded |
|---|---|
| Biosecurity | 100% eradication of invasive Floating Pennywort with zero local contamination. |
| Amphibians & Insects | Successful relocation and safe return of Smooth Newts, Dragonfly Nymphs, and Tadpoles. |
| Flora Restoration | Re-established, clean native Iris, Marsh Marigold, and White Water-Lily. |
| Terrestrial Access | Shallow margins now provide safe drinking and entry points for garden wildlife. |
“Tony has transformed our messy, difficult to maintain wildlife pond into an attractive feature, at the same time providing much better accommodation for the critters which he was very careful to rescue. He and Liam worked like Trojans to transport tons of pond compost, sand, and rocks up our very steep slope... They are both obviously passionate about their work and are fonts of knowledge about pond ecology. An excellent job completed to a high standard, thank you!”
