With the spread of urban developments, transport networks have become important wildlife corridors and havens for biodiversity. However there are a number of species which can be problematic if allowed to colonise the green estate. These fast growing or noxious species can threaten biodiversity, impede maintenance, damage infrastructure and cause complaints from neighbours.
The three most commonly associated with the Highways Environment are Japanese Knotweed, Giant Hogweed and Ragwort. They are so important that their control is covered by legislation, but there are new species such as Himalayan Balsam and Wild Parsnip which are becoming a problem throughout the UK.
LanGuard VM has considerable expertise in the control and eradication of invasive and noxious species on Highways Green Estate including areas adjacent or near sensitive aquatic environments.
