Do a Pollinator Monitoring Survey

“The Pollinator Monitoring and Research Partnership (PMRP) aims to establish how insect pollinator populations are changing across Great Britain.

We are working with existing recording schemes that focus on pollinating insects, and have established new large-scale surveys under the UK Pollinator Monitoring Scheme banner (PoMS)

PoMS is the only scheme in the world generating systematic data on the abundance of bees, hoverflies and other flower-visiting insects at a national scale (currently across England, Wales and Scotland). Together with long-term occurrence records collated by the Bees, Wasps and Ants Recording Society and Hoverfly Recording Scheme, these data will form an invaluable resource from which to measure trends in pollinator populations and target our conservation efforts.

With reports of dramatic losses of insects occurring across the globe, and concern about what this means for wider biodiversity and ecosystem health, there has never been a more important time to document evidence of change in populations of pollinating insects.

FIT Counts: if you can spare ten minutes to sit and watch insects and flowers you can carry out a FIT Count (Flower-Insect Timed Count)! This simple survey collects data on the total number of insects that visit a particular flower, ideally chosen from our list of 14 target flowers. FIT Counts can be done anywhere, including gardens and parks, in warm, dry weather any time from April to September. If you can carry out several counts at one location during that time you will be adding extra value to your survey records. All the information you need is provided on their web site:”

A third of British wild bees and hoverflies are in decline

A widespread loss of pollinating insects in recent decades has been revealed by the first national survey in Britain, which scientists say “highlights a fundamental deterioration” in nature.

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.”

The world’s insects – a “catastrophic collapse of nature’s ecosystems”

The Guardian newspaper reports – “The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review.

More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.”

Insect collapse: ‘We are destroying our life support systems’

Scientist Brad Lister returned to Puerto Rican rainforest after 35 years to find 98% of ground insects had vanished.  A “bottom-up trophic cascade”, in which the knock-on effects of the insect collapse surge up through the food chain.

“I don’t think most people have a systems view of the natural world,” Lister said. “But it’s all connected and when the invertebrates are declining the entire food web is going to suffer and degrade. It is a system-wide effect.”

To understand the global scale of an insect collapse that has so far only been glimpsed, Lister says, there is an urgent need for much more research in many more habitats. “More data, that is my mantra,” he said.

The problem is that there were very few studies of insect numbers in past decades to serve as a baseline, but Lister is undeterred: “There’s no time like the present to start asking what’s going on.”

Social bees are fitter in more biodiverse environments

“Bee population declines are often linked to human impacts, especially habitat and biodiversity loss, but empirical evidence is lacking. To clarify the link between biodiversity loss and bee decline, we examined how floral diversity affects (reproductive) fitness and population growth of a social stingless bee. For the frst time, we related available resource diversity and abundance to resource (quality and quantity) intake and colony reproduction, over more than two years. Our results reveal plant diversity as key driver of bee fitness. Social bee colonies were ftter and their populations grew faster in more forally diverse environments due to a continuous supply of food resources. Colonies responded to high plant diversity with increased resource intake and colony food stores. Our fndings thus point to biodiversity loss as main reason for the observed bee decline.”

New report highlights uncertain future for Welsh wild bees

Buglife Cymru is launching the Wales Threatened Bee Report, the first report of its kind to examine the health of our most threatened wild bee species. Alarmingly, the report has found that seven of our bees have gone extinct in Wales, and a further five – such as the Long-fringed mini-mining bee (Andrena niveata) – are on the brink of extinction. Most of the wild bees species assessed by the report have suffered significant declines, including the Shrill carder bee (Bombus sylvarum) whose core populations are now confined to South Wales, raising concerns about the future prospects of these species.

By examining historical and modern data, Buglife Cymru found that many wild bees in Wales are found in fewer places than they have been found in the past, and face an uncertain future. They also found wild bee declines to be evident across the whole of Wales. Buglife Cymru are now calling for action to restore populations of declining wild bees in Wales.
