Lake District visitors urged to curb spread of invasive weed

New Zealand pigmyweed harms waterways by forming dense mats and depleting oxygen, say experts

Visitors to the Lake District are being asked to help prevent the spread of a particularly bad" invasive weed that could wipe out native species if left unchecked.

Conservation organisations said they were dismayed to find New Zealand pigmyweed spreading rapidly across a number of lakes in the national park, including a previously pristine waterway.

Check all clothing, footwear and equipment for plant fragments and living organisms before leaving a water body. Pay particular attention to any crevices.

Clean and wash all equipment on site, leaving all organisms and plant fragments behind. Or wash on a hard standing surface away from a draining system.

Dry all equipment and clothing thoroughly before heading to the next water body. Some species can survive for two weeks in damp conditions.
