The Times reports oysters are to be reintroduced to the Thames estuary in the hope of reviving production of the shellfish on a scale not seen for centuries.
The oyster population of the Thames has suffered an estimated 95 per cent decline in the past 200 years, due to habitat loss, pollution and disease. Human intervention is now the mollusc’s only hope, according to conservationists from the Zoological Society of London, and work will begin this month to build a new oyster bed in Essex.
The Telegraph reports that gardeners have been urged to pick up their torches and hunt in their gardens for slugs as the Royal Horticultural Society issues a plea for data on the disappearing British bug. [See the full article for details of how to hunt and how to report what you find]
There are worries the Yellow Cellar Slug, which is useful for gardens as it feeds on decaying rather than live plant material, is being usurped by the Green Cellar Slug, originally from Ukraine, which arrived in the 1970s. Since the Green Cellar Slug arrived, numbers of the useful slug are thought to have sharply declined.
While both slugs have large, green-yellow, patterned bodies, the Yellow Cellar Slug has a long yellow stripe running along the centre of its tail.
You can also learn more about these slugs from this Slugwatch guide to the Yellow Cellar Slug and Green Cellar Slug.
