Scotland’s forests are treated and sprayed every year with hundreds of kilograms of a toxic pesticide blamed for killing bees and butterflies, The Ferret can reveal. Our investigation has uncovered widespread use of the nicotine-based insecticide, acetamiprid, by the forestry industry, provoking concerns from experts and alarm from environmentalists who fear “creeping degradation” of nature.
Since 1990, butterfly numbers have dropped by 58 per cent in woods, a government study has found. The report was published in June 2018 by the Department for environment, food and rural affairs (Defra). Woodland species that are struggling include the brown argus, common blue, peacock and purple hairstreak .In response to the report, charities have claimed that reform is needed to the country's farming laws in order to protect the environment in the wake of Brexit. They say the latest figures offer more evidence to support expert predictions of an 'ecological Armageddon'.
Densities and populations of most breeding bird species in Ajloun Forest Reserve have “considerably declined” over the past three years in the evergreen Oak forest, a newly-released study carried out by the studies section at the Royal Society for the Conservation of Nature (RSCN) in 2017 indicated. Ajloun Forest Reserve is located in the Ajloun highlands north of Amman and covers 13 square kilometers.
For many people in Hong Kong, talk of endangered species conjures up images of wildlife whose natural habitats are “out there”, somewhere far away – such as giant pandas in the bamboo forests of Sichuan province, polar bears in the Arctic and miniature monkeys in the Brazilian rainforest. If, like me, you are a birdwatcher, however, the list of threatened species feels far closer to home.
Of the four subspecies of willow flycatcher (Empidonax traillii), three have breeding grounds in California and are listed as endangered by the state's Department of Fish and Wildlife. Because the southwestern subspecies, one of those three subspecies, is listed as endangered by the federal Fish and Wildlife Service, ecologists and conservation biologists have studied the birds closely for decades.
A while back we took note of a study that showed populations of airborne insects have declined by 76 percent in protected areas in Germany over the past 27 years. Part of the picture was that the disappearance of bugs is likely to pose problems for other animals in the food chain. Now a recent study by French scientists revealed that bird populations in France’s farming areas have declined by more than one-third in the past 17 years. Both resident and migrant species have decreased sharply.
In heel West-Europa zijn we in enkele tientallen jaren misschien wel de helft van de koekoeken (Cuculus canorus) kwijtgeraakt. Een van de oorzaken is de afname van dag- en nachtvlinders. Koekoeken leven van de rupsen van deze vlinders. In Groot-Brittannië is er een duidelijke relatie gevonden tussen de afname van de koekoek en een sterke afname van rupsen. Het is heel waarschijnlijk dat ook in Nederland het aanbod van voedsel is afgenomen. Dit zal vooral invloed hebben op de periode net na uitvliegen wanneer de jonge koekoek zelf voedsel moet verzamelen en overschakelt op rupsen.
There has been decline in the population of birds in Athagarh forest division in Cuttack. At least 16,948 birds were sighted in the forest division during the bird census which was carried out in the first week of January. The number of birds counted this year is much less against last year's 19,476. Adding to it, not a single migratory bird has been spotted in the region this time.
As their common name implies, the woodcocks (Scolopax rusticola) are woodland birds. They feed at night or in the evenings, searching for invertebrates in soft ground with their long bills. The population of British woodcock is now so imperilled that a game-shoot owner turned conservationist has started a national campaign to save the dwindling species. Figures indicate the number of breeding woodcock males has shrunk to possibly fewer than 55,000, down 30 per cent since 2003. Experts suggest that numbers could have been affected by collapsing insect populations.
