Stille ramp: de insecten verdwijnen

Er zijn steeds minder insecten. Uit onderzoek blijkt dat de hoeveelheid insecten in de natuurgebieden rond het Duitse Krefeld met bijna 80% is afgenomen in 25 jaar van 1989 tot 2014. Een afname die volgens een publicatie in Science niet alleen in Duitsland geconstateerd wordt, maar ook in andere landen. Zo daalde het aantal insecten in Schotland met 60%. Het onderzoek in Krefeld werd uitgevoerd in natuurgebieden waar niet zo extreem veel was veranderd in het beheer van die gebieden zelf. Maar in de omgeving is wel veel veranderd.

British wildlife is in serious trouble

Populations of farmland, woodland and marine birds have all fallen dramatically over the past 50 years, according to new government figures. In all bird species, populations have declined by six per cent since 1970, but some species saw stunning declines over the past five decades, as pesticides, the intensification of farming and the removal of hedgerows wreaked havoc. Bird populations are seen as a key indicator of the health of the natural world as they tend to feed on small insects that are the basis of the food chain.

Bird populations in steep decline in North America

North America has more than a billion fewer birds than it did 40 years ago, with the snowy owl (Bubo scandiacus) and the chimney swift (Chaetura pelagica) just two of the better-known species in dramatic decline across the continent, a recent survey has found. The total number of continental landbirds stands at about 10 billion, down from about 11.5 billion in 1970.

Pesticides affect pheasant abundance in California

Based on count data compiled from Breeding Bird Survey (BBS) from 1974 to 2012, Christmas Bird Count (CBC) collected from 1914 to 2013, and hunter data from Annual Game Take Survey (AGTS) for years 1948–2010, ring-necked pheasants (Phasianus colchicus) in California have experienced substantial declines in agricultural environments. An additional analysis using a restricted data set (1990–2013) indicated recent negative impacts on pheasant numbers associated with land use practices were also associated with relatively high levels of pesticide application.

Bird decline in Bulgaria after the country joined the EU in 2007

Based on monitoring data for the period 2005-2010, we studied the trends in abundance and species richness of common breeding birds in Bulgaria before and after the country joined the EU in 2007. We analysed the trends in birds of farmland, woodland and “other” habitats, and additionally, we tested whether indices of the commonest birds are representative of wider changes in bird populations. At species level (n = 32), significant declines were detected in 11 species (34%), and increases in just two (6%); 19 species (60%) had uncertain trends.

'Dramatic' decline in European birds linked to industrial agriculture

The number of birds in Germany and Europe has dropped significantly over the past 30 years, according to the German government. In Germany, one-third of all bird species have seen "significant population declines" since the end of the 1990s, said the government in response to a question about the plight of birds across Europe put forward by the Greens. "The situation of birds is dramatic," said Steffi Lemke, a German Green Party lawmaker.

Immer weniger Vögel in Niedersachsen

Die Zahl der Vögel in Niedersachsen geht weiter zurück. Im vergangenen Winter seien etwa 17 Prozent weniger Vögel gezählt worden, berichtet der NDR. Insgesamt über 40 Vogelarten stehen nach Angaben der Vogelschutzwarte Niedersachsen auf der sogenannten Roten Liste. Ein Grund für den Rückgang des Vogelvorkommens liegt in der Landwirtschaft. Weil Landwirte immer mehr Pestizide einsetzten, sterben viele Insekten. Die fehlen dann den Vögeln als Nahrung. Daher fordert Niedersachsens Umweltminister Steffen Wenzel, den Einsatz von Pestiziden stärker einzudämmen.

Erst sterben die Insekten, dann die Vögel

Die Zahl der Vögel in ganz Deutschland und Europa geht dramatisch zurück. Vor allem Vögel, die in Agrarlandschaften leben, sind bedroht. In einer Antwort auf eine Kleine Anfrage der Grünen, die der Deutschen Presse-Agentur am Donnerstag vorlag, hat die Bundesregierung die Zahlen zusammengetragen: Insgesamt ist demnach in der EU die Zahl der Brutpaare in den landwirtschaftlichen Gebieten zwischen 1980 und 2010 um 300 Millionen zurückgegangen, ein Minus von 57 Prozent.

Declining numbers of Blue-tailed bee-eater worry conservationists

Once sighted in the thousands, the Blue-tailed bee-eater is a sparsely spotted bird these days. Bird watchers and photographers say their numbers have significantly declined from thousands to a few hundreds in the last five years. In South India, the tiny beauty is endemic to Chandagala, a village on the banks of River Cauvery and close to the historic town of Srirangapatna in Mandya district. The Blue-tailed bee-eater (Merops philippinus) is migratory by nature. The bird is found in peninsular parts of the country.
