Change to Monmouthshire’s mowing practices

“As spring approaches, Monmouthshire’s grounds maintenance service will work to support the environment and provide a boost for wildlife by modifying mowing practices. Teams will mark open spaces with blue or white topped stakes to highlight areas likely to be suitable habitats which have been identified by council staff, residents or through the council’s partnerships with local groups. These include Bee Friendly Monmouthshire, Bees for Development and Gwent Wildlife Trust as part of the Nature Isn’t Neat project funded by the Vale of Usk Rural Development Plan for Wales …”

Strips of wildflowers could cut pesticide spraying

Strips of wildflowers across farm fields could cut pesticide spraying.   Guardian newspaper report:-

“The stripy fields have been planted across England as part of a trial to boost the natural predators of pests that attack cereal crops.

Long strips of bright wildflowers are being planted through crop fields to boost the natural predators of pests and potentially cut pesticide spraying.  The strips were planted on 15 large arable farms in central and eastern England last autumn and will be monitored for five years, as part of a trial run by the Centre for Ecology and Hydrology…. ”

Buy organic to help curb global insect collapse.

A Guardian newspaper article ,,,  “Buying organic food is among the actions people can take to curb the global decline in insects, according to leading scientists. Urging political action to slash pesticide use on conventional farms is another, say environmentalists.”

Bumblebees use perfume patterns to tell flowers apart

Guardian newspaper report ….

“Pollinators don’t just wing it when it comes to finding a sweet treat: the shape, colour, perfume and even electrical charge of flowers are all known to offer clues.

But now researchers say bumblebees also use another floral feature to guide them: how the concentration of a scent varies across the flower’s surface.”

Warning of ‘Ecological Armageddon’ after dramatic plunge in insect numbers

The Guardian reports that a recent study shows the abundance of flying insects has plunged by three-quarters over the past 25 years.

Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is “on course for ecological Armageddon”, with profound impacts on human society.

The new data was gathered in nature reserves across Germany but has implications for all landscapes dominated by agriculture, the researchers said.

The cause of the huge decline is as yet unclear, although the destruction of wild areas and widespread use of pesticides are the most likely factors and climate change may play a role. The scientists were able to rule out weather and changes to landscape in the reserves as causes, but data on pesticide levels has not been collected.
