Dothistroma needle blight In Britain, Dothistroma Needle Blight (DNB), also known as Red Band Needle Blight, is caused by the fungus Dothistroma septosporum. It has been found on a range of conifer species, but pine (Pinus) are by far the most common hosts, with Corsican pine, lodgepole pine and Scots pine all now affected. Infected needles typically develop yellow and tan spots and bands, which soon turn red. The ends of the needles then turn reddish-brown whilst the needle base remains green. Needle symptoms are most apparent in June and July when the spore-containing fruit bodies are most abundant, after which the infected needles are lost and trees can have a typical ‘lion's tail’ appearance, with only a tuft of the current year's needles remaining at the branch ends. www.forestry.gov.uk/redbandneedleblight

MPs to study handling of ash dieback Published 1 minute ago There are hopes that some British ash trees may be innately resistant to the Chalara fraxinea fungus The Government’s handling of the ash dieback infestation is to be investigated by MPs. Present and former ministers are expected to be among the witnesses called to give evidence to the Environment Select Committee about how the disaster was allowed to happen and how it will be dealt with in future, a source said. They will also be asked to explain the dearth of funding for monitoring and studying the diseases threatening Bitain's trees. www.thetimes.co.uk/tto/environment/article3592363.ece

World's Big Trees Are Dying: Alarming Increase in Death Rates Among Trees 100-300 Years Old Dec. 6, 2012 — The largest living organisms on the planet, the big, old trees that harbour and sustain countless birds and other wildlife, are dying. A report by three of the world's leading ecologists in today's issue of the journal Science warns of an alarming increase in deathrates among trees 100-300 years old in many of the world's forests, woodlands, savannahs, farming areas and even in cities. "It's a worldwide problem and appears to be happening in most types of forest," says lead author Professor David Lindenmayer of the ARC Centre of Excellence for Environmental Decisions (CEED) and Australian National University. www.sciencedaily.com/releases/2012/12/121206162519.htm

Another explosion BC sawmills the average temperature in Fort McMurray has increased by 1.65 °C since 1960the 'energy industry' has said that area's contamination is 'natural' -- furthermore, the 'energy industry' has said that they are actually 'cleaning up' Pollutants in Lakes Linked to Oil Sands -- January 8, 2013. Some of the world’s largest reserves of crude oil are held in the oil sands in Alberta, Canada, and production has been ongoing. A new study shows that contaminants from the development of the sands are stacking up in the environment. The scientists published their findings in the journal Proceedings of the National Academy of Sciences¹. The researchers studied five lakes near mining and upgrading operations around Fort McMurray, Alberta, and another lake 90 kilometers northwest. They found that the levels of polycyclic aromatic hydrocarbons (PAHs), which are carbon-based compounds, some of which can be toxic or carcinogenic, in lake sediments have been on the rise since the 1960s. By 2011, PAH levels in these lakes ranged from 2.5 to 33 times higher than before 1960. scitechdaily.com/pollutants-in-lakes-linked-to-oil-sands/

Current cold snap not enough to disrupt Colorado pine beetle threat Updated: 2 months ago Temperatures would have to drop to minus 30 or lower and stay there for at least five to seven days for nature to hit back at the pine beetle from December through February, Leatherman said. The current beetle infestation has already claimed about 6.6 million acres of lodgepole pine forests in the state, according to the Colorado State Forest Service. www.denverpost.com/news/ci_24672322/current-cold-snap-not-enough-disrupt-colorado-pine

Olive oil prices surge due to drought and disease in Spain and Italy Producers say this year’s harvests are worst they have seen, as consumer demand begins to outstrip supply Friday 24 July 2015 19.42 BST The Italian government has declared a “state of calamity” in the provinces of Lecce and Brindisi on the heel of the country, where olive groves are being attacked by a bacterial disease nicknamed “olive ebola” . Up to 1m centuries-old olive trees could be felled in one of the most picturesque tourist spots of Italy in an attempt to contain the problem. The cost of the raw material has been increasing for two years as crops have been hit by drought in Spain, the world’s biggest producer of the oil, and the bacterial disease Xylella fastidiosa, which is destroying trees in Italy. www.theguardian.com/environment/2015/jul/24/olive-oil-prices-surge-drought-disease-spain-italy
