Migrant birds lose breeding grounds to poor farm management Posted on: 04 Sep 2015 Up to 65 per cent of bird species use farmland as breeding habitat, but the barrenness of much of it is causing rapid declines. Migratory birds like Swallow or Montagu’s Harrier which breed in Europe in summer before migrating to warmer climes in autumn mare struggling to find appropriate breeding habitat, says BirdLife International. Farmland is a very important habitat for migratory birds, as up to 65 per cent of those species use it at some stage during their life cycle. “Species and habitats which depend on agricultural ecosystems are doing worse than those in general assessments,” states the EEA’s State of the Environment in Europe report. Against the doom and gloom stand the Birds and Habitats Directives.
Other News Kuwait becomes Ramsar state. Theconversation. Each year, humans reduce the number of trees worldwide by 15 billion. This is one of the startling conclusions of new research published in the journal Nature. The study also estimates the Earth is home to more than three trillion trees – that’s 3,000 billion – so you may think that while 15 billion is a very large number, humans shouldn’t be at risk of making significant changes to global tree cover. However, the team of 31 international scientists led by Thomas Crowther at Yale University also present evidence that the rise of human civilisation has reduced the numbers of trees on Earth by 46%.
In many areas we can’t see the wood because there are no trees. Unlike polar bears, pandas or peregrine falcons, trees and their demise typically do not generate much passion or protest. Previous estimates for the total number of trees on Earth have been much lower. Humans have long used trees as fuel for cooking or smelting, fibres for clothes, timber for construction.
La humanidad ya ha destruido la mitad de todos los árboles del planeta. Es el tipo de pregunta que deja sin guardia a cualquier padre y que ni las mejores mentes han podido responder de forma satisfactoria: ¿Cuántos árboles hay en el mundo? Un nuevo estudio acaba de aportar el cálculo más preciso hasta el momento y los resultados son sorprendentes, para lo bueno y para lo malo. Hasta ahora se pensaba que hay 400.000 millones de árboles en todo el planeta, o 61 por persona. El recuento se basaba en imágenes de satélite y estimaciones del área forestal, pero no en observaciones sobre el terreno. Después, en 2013, estudios basados en recuentos directos confirmaron que solo en el Amazonas hay casi 400.000 millones de árboles, por lo que la pregunta seguía en el aire. Y se trata de un dato crucial para entender cómo funciona el planeta a nivel global, en especial el ciclo del carbono y el cambio climático, pero también la distribución de especies animales y vegetales o los efectos de la actividad humana en todos ellos.
Europa deforestada. Theconversation. By the end of the century, the world’s remaining tropical forests will be left in a fragmented, simplified, and degraded state. No patch will remain untouched – most remnants will be overrun by species that disperse well, which often means “weedy” plants like fast-growing pioneer trees and small rodents that thrive in disturbed areas. Most of the rest will be “the living dead” – tiny remnant populations of plants and animals hanging on with no future.
There is no cast-iron law that dictates this scenario – but it appears likely unless we see a series of major policy changes. What could unfold? The first cut of timber from any natural forest is the most lucrative. Today, less than 25% of tropical forests have escaped industrial logging and each year new concessions are given to industrial loggers in forests that had hitherto never been logged. Logging pushes roads into the forest. Heavily logged and degraded forest is then often slated for conversion to agricultural plantations.
150820212652. The fact that the greatest diversity of large mammals is found in Africa reflects past human activities -- and not climatic or other environmental constraints. This is determined in a new study, which presents what the world map of mammals would look like if modern man (Homo sapiens) had never existed. In a world without humans, most of northern Europe would probably now be home to not only wolves, Eurasian elk (moose) and bears, but also animals such as elephants and rhinoceroses. This is demonstrated in a new study conducted by researchers from Aarhus University, Denmark. In a previous analysis, they have shown that the mass extinction of large mammals during the Last Ice Age and in subsequent millennia (the late-Quaternary megafauna extinction) is largely explainable from the expansion of modern man (Homo sapiens) across the world.
"Northern Europe is far from the only place in which humans have reduced the diversity of mammals -- it's a worldwide phenomenon. Africa is the last refuge. Rewilding: Movement to restore wilderness areas is growing across Europe - Travel - The Independent. A safari at the Knepp Wildland Project in West Sussex is very much in this vein. Knepp Castle and its 3,500 acre estate is home to Charles and Issy Burrell and has been in the family for 220 years. Until 15 years ago the couple farmed the land, but the soil was heavy clay and they struggled to make ends meet. Then a visit to the Oostvaardersplassen project in the Netherlands sent them in a new direction.
The Dutch had returned some reclaimed lowlands in Flevoland to their Palaeolithic state and the success they are having – rare buzzards, goshawks, kestrels, kingfishers, eagles (and even a wolf) turned up – has launched a European “rewilding” movement. Indeed, George Monbiot helped launch the controversial Rewilding Britain movement only last month, in the hope of reintroducing up to 15 species to our islands, from lynx to grey whales. All across the continent there is farm land that is economically marginal.
Charles and Issy were converted and they hurried home to do… nothing. Feds allow Shell to drill for oil in Arctic Ocean off Alaska. The federal government on Monday gave Royal Dutch Shell the final permit it needs to drill for oil in the Arctic Ocean off Alaska's northwest coast for the first time in more than two decades. The Bureau of Safety and Environmental Enforcement announced that it approved the permit to drill below the ocean floor after the oil giant brought in a required piece of equipment to stop a possible well blowout. The agency previously allowed Shell to begin drilling only the top sections of two wells in the Chukchi Sea because the key equipment, called a capping stack, was stuck on a vessel that needed repair in Portland, Oregon.
Because the vessel arrived last week, Shell is free to drill into oil-bearing rock, estimated at 8,000 feet below the ocean floor, for the first time since its last exploratory well was drilled in 1991. The Polar Pioneer, a semi-submersible drilling unit that Shell leases from Transocean Ltd., began work July 30 at Shell's Burger J site. The U.S. New research reveals climate change threat to uplands. Print page Last modified: 31 July 2015 Several rare upland bird species are being put at risk together with other ecosystem functions by the effects of climate change on the UK’s blanket bogs, ecologists at the University of York have discovered.
Most of our drinking water comes from these upland peats and several iconic bird species such as the dunlin, golden plover and red grouse depend on these wetland habitats for nesting and feeding. The scientists warn that climate change threatens these habitats, not only from rising temperatures increasing peat decomposition, but also via altered rainfall patterns – with summer droughts drastically affecting the blanket bog hydrology. The birds depend on the protein rich craneflies as food for chicks, but scientists have discovered that summer droughts, which are predicted to increase, will cause significant declines in crane flies and subsequently the bird species that depend on them. The results have been published in Nature Communications. Los efectos de los retardantes de llama persisten diez años tras los incendios.

Only China Can Save the Seas [Commentary] EU wants stiff penalties and wiretaps to fight environmental crime | Environment | The Guardian. Lenient penalties for environment crimes, such as the suspended sentence handed down to a former gamekeeper who poisoned buzzards, hamper law enforcement and obstruct police efforts to get authorisation for vital wiretaps, the head of an EU environmental crimes unit has told the Guardian.
Leif Gorts, who leads a team at Eurojust, was speaking as the cross-border crime-fighting agency launched its first environmental crimes report, showing a dearth of prosecutions in Europe with low penalties, under-reporting, poor cross-border cooperation and corruption all hobbling enforcement efforts. “We need stronger penalties so we can get wiretapping and other investigative measures authorised to fight organised crime,” Gorts said. “In my country, Sweden, we have four years as a maximum penalty, so we can wiretap people who are conspiring to kill wolves, for example.”
“The interception of communications is very seldom used in cases of trafficking in endangered species,” the Eurojust report says. Technologies and innovations to better understand changes in land use - Global Landscapes Forum. Technology and big data are transforming the way we monitor forests and climate in a post-Kyoto world. Static studies have given way to a stream of real-time information used by governments, businesses, and communities to better manage forests for conservation, for economic benefit, and for carbon.
Several such ground-breaking new remote-sensing data products related to estimating emissions from deforestation around the world will be launched at COP 20 (featured on Global Forest Watch). But top-down data from remote sensing can have huge gaps and important limitations. This session aims to encourage a frank and open discussion about the limitations of remotely sensed and crowd-sourced data and their usefulness. Another important aspect is the question which direction of future data development is needed so that forest monitoring programs are cost-effective and universally accepted. Participants are welcome to also discuss other technologies, such as lidar, radar, drones, crowdsourcing.

Meet 7 new endangered species on the IUCN Red List | MNN - Mother Nature Network. Earth's preeminent list of endangered species marks its 50th anniversary this year, but there isn't much time to celebrate.
With nearly a third of all surveyed species at risk of disappearing, and potentially millions more still unsurveyed, the International Union for Conservation of Nature (IUCN) Red List is scratching at the surface of what increasingly looks like a worldwide wildlife extinction crisis. The IUCN Red List has so far surveyed 76,199 species, nearly halfway to its goal of surveying at least 160,000 species by 2020.
This week the group announced that 22,413 of those are threatened with extinction, an increase of 310 species since its last update five months ago. This is part of a long-simmering crisis many scientists now describe as a mass extinction event. The IUCN has already assessed most mammals and birds, but it still has a long way to go with less visible, relatable or charismatic creatures such as fish, insects, plants and fungi. Photo: IUCN. Why natural conservation methods matter for the future of urban water supplies | MNN - Mother Nature Network.
The liquid that comes cascading out of the faucet each time you step up to the sink to brush your teeth, wash your hands or refill your self-cleaning, basil-growing aquarium has to come from somewhere, you know. And unless the municipal water supply in your city or town has been compromised or you are hyper-aware of personal water usage due to drought, there’s a good chance you might not know where that somewhere is. In addition to the report itself, Urban Water Blueprint includes a fascinating interactive website that details the state of 2,000 water-supplying ecosystems and the 530 cities across the globe, home to more than 1 billion people, that draw from them. The water situation — including specific risks such as agricultural runoff and erosion and the management solutions that should be employed to remedy them in conjunction with traditional infrastructure — in a handful of major cities ranging from Los Angeles to New York, London to Beijing are explored in further detail.
Conservation deal saves world's largest bat colony. With white-nose syndrome sweeping some parts of the country and killing millions of bats, there's rarely any good news to share about these cave-dwelling mammals. But the bats of Bracken Bat Cave have reason to celebrate, thanks to a $20 million deal signed on Halloween to protect these animals from a housing development that would have threatened the world's largest bat colony. Located outside of San Antonio, the cave is home to the largest colony of Mexican free-tailed bats in the world with 15 million to 20 million bats. Many of the bats are pregnant and nursing females are coming back from wintering in Mexico. "They deposit the baby in what we call the nursery section of the cave, which is just millions of hairless baby bats, so when you look at it, it's a ceiling of pink, hairless baby bats," Fran Hutchins, coordinator of the cave for Bat Conservation International (BCI), told NPR.
