The Tree Sparrow (Passer montanus) colony at Beddington Farmlands – which used to be one of the biggest in England – is all but lost following a shocking decline of the species at the London site, with analysis in the Beddington Farmlands 2019 Bird and Wildlife Report suggesting failed habitat management as the key factor.
The grey partridge (Perdix perdix) has been deemed extirpated from Switzerland following a year of no sightings in 2019, marking a sad demise for a species once common in the land-locked European nation. Last year's blank came after only two breeding pairs were found in the Geneva region in 2018. Given their sedentary nature, a recurrence of the species is considered very unlikely.
In Limburg worden veel planten- en diersoorten die uniek zijn voor deze regio ernstig bedreigd. Er is een lijst van 28 bedreigde diersoorten die binnen Nederland alleen – of in belangrijke mate – in Limburg voorkomen.
Sinds 1990 zijn populaties wilde dieren in zowel open natuurgebieden zoals heide, als in het agrarisch landschap, gemiddeld gehalveerd. Diverse vogel-, vlinder- en reptielensoorten die vroeger algemeen voorkwamen zijn tegenwoordig zeldzaam. Deze zorgwekkende ontwikkeling blijkt uit het vandaag door het Wereld Natuur Fonds (WWF-NL) gepubliceerde Living Planet Report Nederland, getiteld ‘Natuur en Landbouw Verbonden’.
In the summer of 2010, Henk Tennekes from Experimental Toxicology Services Nederland at Zutphen warned that the accumulation of neonicotinoids in the environment would not only decimate useful insects but also have a knock-on effect on other species, including birds (Curr. Biol. (2011) 21, R137–R139). At the time, Tennekes did not find much support for his views and went on to publish his warnings as a book — The Systemic Insecticides: A Disaster in the Making.
In de jaren negentig kregen universiteiten het credo van de marktwerking opgelegd. De overheid bepaalde dat wetenschappelijk onderzoek niet langer alleen uit publieke middelen moest worden gefinancierd, maar voortaan ook deels met extern geld. Dat betekende dat universiteiten de boer op moesten. Voor Wageningse onderzoekers betekende dat het begin van een innige samenwerking met chemiegiganten.
The renowned author and whistleblower Evaggelos Vallianatos describes British environmentalist and campaigner Dr Rosemary Mason as a “defender of the natural world and public health.” I first came across her work a few years ago. It was in the form of an open letter she had sent to an official about the devastating environmental and human health impacts of glyphosate-based weed killers. What had impressed me was the document she had sent to accompany the letter.
A recent study concludes that the birds of Canada and the United States have taken a substantial hit in the last 49 years. Researchers from several institutions in the U.S. and Canada, including the American Bird Conservancy, the Bird Conservancy of the Rockies, the Cornell Laboratory of Ornithology, and Environment and Climate Change Canada, joined forces for the study.
Birdwatch Ireland's research has shown that the country has lost half a million waterbirds or almost 40% in less than 20 years. Among species in decline are Lapwing (Vanellus vanellus), Mallard (Anas platyrhynchos), Tufted Duck (Aythya fuligula), Goldeneye (Bucephala clangula) and Pochard (Aythya ferina). It says that there has been an "almost complete extermination" of farmland birds such as the Corncrake (Crex crex).
Schon 20 Feldvogelarten, darunter Braunkehlchen, Rebhuhn, Kiebitz oder Uferschnepf, sind rund um Kassel nicht mehr zu sehen, da diese Arten bereits ausgestorben sind. „Und um den Neuntöter ist es auch schon schlecht bestellt, ebenso um die Feldlerche, den Vogel des Jahres 2019“, sagen Manfred Henkel und Martin Lange vom Nabu Kaufungen-Lohfelden. Im Landkreis sei ihr Bestand dramatisch gesunken. Die beiden Naturschützer läuten Alarm. Nachdem vor rund einem Jahr das Insektensterben in den Medien ein großes Thema war, sind es nun die Feldvögel.
