It looks as if it might be curtains for yet another UK tree species with the discovery of the ash die-back fungus Chalara fraxinea in a Woodland Trust area in East Anglia (http://www.guardian.co.uk/environment/2012/oct/24/ash-dieback-disease-east-anglia?INTCMP=SRCH). The Ash (Fraxinus excelsior) is a common stand alone tree and can be a major component of hedgerows. The fungus can easily spread tens of kilometres as spores on the wind. Although the fungus has been recorded in the UK previously, it has, thus far, been limited to garden centres and imported trees (now banned) and its eradication has been relatively easy. Now it's into wild populations, the spread of the disease will be almost impossible to contain. A substantial proportion of the Ash in Danish forests has already disappeared.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Costing the Earth
The UN has warned that climate change is dramatically increasing the costs of basic foods over substantial areas of the globe. Awful summers have disrupted wheat production (in terms of amount and quality) in America, Russia and the UK (http://www.guardian.co.uk/environment/2012/oct/10/un-rising-food-costs-weather?INTCMP=SRCH). Then, on top of that, some grain is diverted to make biodiesel.
Washed Away!
The plethora of insect life in Sikkim just serves to underline what a truly awful summer 2012 has provided for our invertebrates. Apparently, slugs and snails are thriving (http://www.guardian.co.uk/commentisfree/2012/jul/16/wildlife-apocalyptic-summer-damp-weather?INTCMP=SRCH) but butterflies and moths are in a spiral of serious decline.

More Critters from Sikkim
Got a nice shot of a wild Hanuman langur monkey and some close ups of a type of dove , a yellow-fronted bird and a Drongo (birds). Butterflies were also spectacular including this Paris peacock (Papilio paris) and a male Yellow orange-tip (Ixras pyrene). Shot a very weird dragonfly (a female Anisopteran Palponeura seximaculata ) and some interesting relatives of the grasshopper (colour morphs of Mecopoda).
