World Rainforest Week 12 - 18 October




To celebrate World Rainforest Week I have posted just a few of  images that show the  amazing beauty of  the rainforests. But photographs do not convey the awesome nature of the rainforest - the size and complexity of the vegetation, and the overloading of one's senses from the  cacophony of insects, frogs and birds, the smell of decay, the lack of light  and the humidity that saps your body of energy.

The pressure on the forests continues - oil palm and rubber plantations,  clearance for cattle ranching, oil exploration, mining, quarrying, for timber etc etc. The list goes on and on.  Now the Rainforest Action Network (RAN) are highlighting yet another threat - this time to the temperate rainforests of British Columbia. The exploitation of the tar sand deposits in Alberta continues and a pipeline is proposed to take millions of barrels of oil  to Kitimat on the Pacific coast, from where it will be shipped around the world. I have visited this part of Canada and it is beautiful. I took the ferry along the Inside Pasage where we passed  forested islands separated by narrow channels. The region is rich in wildlife, both in the sea and on the land.


So whats the problem with the pipeline? The tankers travelling to and from Kitimat will have to pass along treacherous shipping routes where accidents are common. A navigation accident with an oil tanker could lead to millions of tonnes of oil pollution the pristine waters. Its not hard to imagine what would happen, one has just to think of Exxon Valdez. To find out more about this threat, read the excellent article on the RAN blog (http://understory.ran.org/2009/10/05/tar-sands-threaten-canadas-rainforests/)

Billions of butterflies


This year the UK has been invaded by an army of painted lady butterflies. The painted lady is a summer migrant, flying from Europe and North Africa. The conditions in North Africa this year were superb and the adults, strong fliers, have dispersed through Europe. Scientists estimate that one billion painted ladies will be on the wing in the UK in August, some having flown over from Europe and others emerging from pupae from the first arrivals back in June.
Its a bumper year for the Painted Lady and other common species such as the Peacock, Small Tortoiseshell, Red Admiral and Meadow Browns but sadly, others are not doing so well - fritillaries for example. Its not due to competition with other butterfly species, but habitat loss.
On the butterfly conservation website (http://www.butterfly-conservation.org) you can log your sightings of this butterfly as well as those of the humming-bird hawkmoth. This moth is a day flying species that is often seen sipping nectar from flowers using its extra ong proboscis. It gets its name from the way it hovers in front of the flower, just like a hummingbird.
