Project Title: RSPB Medbury Seabird Nesting Restoration

 

Objective:

The primary goal of this project was to restore critical seabird nesting areas on a series of islands managed by the RSPB. Due to challenging site access, the project required innovative solutions to ensure a safe and effective habitat restoration.

 

Challenges:

The site consisted of four islands situated on a tidal estuary, accessible only on foot at low tide. All heavy equipment and materials had to be transported by barge, and amphibious excavators were essential to reach the work areas.

 

Equipment and Solutions:

To tackle these challenges, the team deployed a 16-ton excavator using biodegradable hydraulic oil for environmental safety. This excavator helped load pans and barges, which were then tugged to the islands. Two amphibious excavators capable of floating under their own power were used to navigate the terrain, and a hovercraft was on hand for safety and rescue operations.

 

Restoration Process:

The restoration involved several key steps. First, a Green Climber 600 was transported to the islands to cut down excess vegetation. The excavators then scraped back the remaining vegetation to expose the shingle bank. Once the area was cleaned, predator fence posts were installed around the islands, and an artificial high-tide line was created using natural debris. Finally, a saltwater treatment was applied to prevent vegetation regrowth.

 

Outcomes and Feedback:

The project was completed ahead of schedule and exceeded the client’s expectations. Within two to three weeks of completion, seabirds had returned and begun nesting. RSPB was so pleased with the high-quality outcome.
