Amphibious vehicle battles algae
AN amphibious vehicle was in action at the National Trust’s Stourhead last week, mechanically removing the invasive blanket weed that has covered much of the lake this summer at the world famous landscape garden.
The machine, a cross between a digger with caterpillar tracks and a boat with large forks on the front, could be seen for two days scooping out large amounts of the algae from the lake. The vehicle when fully loaded weighs two tonnes, so an enormous amount of algae was removed.
The algae was then stacked and left to dry at the side of the lake, allowing any wildlife to crawl back into the water. Once dry, the algae will be removed and put in to compost heaps, as it makes great compost material.
Stourhead is currently undertaking an extensive review process with an outside agency to assess and put in place a strategy and policy of how best to long term deal with the weed and algae problems on the lakes.
