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'.
A great many birds eat a great many bugs: this is something that, in general, we already know. But just how much do they eat? Empirical figures are hard to come by — but according to a new estimate, published in the journal The Science of Nature, the total figure is truly breathtaking, roughly equivalent to the weight of meat and fish consumed each year by humans.
“SEE those little beetles with a black cross on a red background?” I lean in to take a look. “They’re Panagaeus cruxmajor – the crucifix ground beetle. They were collected by Charles Darwin back in the 1820s.” Ed Turner is curator of insects at the University of Cambridge’s Zoology Museum, where many of Darwin’s beetle collections are held. He is proud to show me specimens collected by the man himself, and I am chuffed to see them. But the thrill doesn’t last.
Het lijkt misschien prettig, minder insecten die van de voorruit gewassen moeten worden of ons lastig vallen in de tuin. Maar de massale insectensterfte is vooral heel zorgelijk en gevaarlijk voor de kringloop van het leven. Al jaren neemt het aantal insecten af, in sommige gebieden is in de afgelopen decennia zelfs een daling tot 75% geregistreerd. Dit blijft niet zonder gevolgen. Ecoloog Jan Doevendans volgt al tientallen jaren de zwaluwpopulaties. Sinds de jaren ’70 heeft hij honderden nestkasten opgehangen, onder meer in Groningen en het Lauwersmeergebied.
New research led by scientists at the University of Bristol has uncovered that long-term use of some pesticides to treat cattle for parasites is having a significantly detrimental effect on the dung beetle population. Researchers studied 24 cattle farms across south west England and found that farms that used certain pesticides had fewer species of dung beetle. Dr Bryony Sands, from the University's School of Biological Sciences, who led the research, said: "Dung beetles recycle dung pats on pastures, bringing the nutrients back into the soil and ensuring the pastures are fertile.
Seit 14 Jahren ruft der NABU inzwischen Anfang Mai zu Vogelzählaktionen auf. In diesem Jahr waren die Menschen bundesweit von Vater- bis Muttertag dazu aufgerufen, die Vögel im heimischen Garten zu zählen. Bis zum vergangenen Montag konnten die Teilnehmer die Ergebnisse melden. Während sich die Veranstalter über die rege Beteiligung freuen - 53.000 Vogelfreunde haben sich zurückgemeldet - finden sie die Ergebnisse besorgniserregend. Denn unter den Top 15 der Gartenvögel weisen sieben Arten so geringe Zahlen auf wie noch nie.
Bird protection organisation Vogelbescherming has named 2018 the Year of the House Martin in an effort to call attention to the dramatic decline of this migratory bird in the Netherlands, public broadcaster NOS reports. Together with bird research group Sovon, Vogelbescherming has mobilised a group of volunteers to find the cause of the dwindling numbers of house martins (Delichon urbicum). Since 1970 some 80% fewer house martins have been spotted in this country and it is thought that since 1920 the decline could be as much as 95%.
Scientific research commissioned by Natuurmonumenten shows that the number of insects is declining dramatically in the Netherlands. Measurements and analyses in recent decades show a decline of 54 percent (ground beetles) and 72 percent (ground beetles) in nature reserves. This represents a dramatic fall in these groups of insects, which is in line with the results of recent German, French, English and Dutch studies. And this is bad, as it has a huge impact on the cycle of life.
