New book published on the population genetics of Himalayan balsam (Impatiens glandulifera) which compares native and introduced populations.
It look at how invasive species can interfere in the structure and functioning of ecosystems, and how a better understanding of the evolution of such species will be useful when planning their management and eradication.
A new paper discusses biological control (using natural enemies) of plants that have escaped from gardens and are invading wild habitats in UK. These include Japanese knotweed, Himalayan balsam, Australian swamp stonecrop, floating pennywort, giant hogweed, water fern, rhododendron and buddleja.
Volunteers from RINSE (Reducing the Impact of Non-Native Species in Europe) performed a survey of the River Bure (in the Norfolk Broads), tracking it from source to sea and seeing how many invasive plants such as Himalayan balsam they cam across.
