The way the world is – now!

There has been a wealth of information going past my ‘desk’ in the last couple of days that gives plenty of cause to worry.  But I’m going to spend a few days mulling it all over rather than react in some ‘knee-jerk’ fashion.

However, a couple of stories caught my eye a few days ago on the BBC News website and seemed worthy of sharing with you.

The first was,

Mild drought caused Maya collapse in Mexico, Guatemala

Relatively mild drought conditions may have been enough to cause the collapse of the Classic Maya civilisation, which flourished until about AD950 in what is now southern Mexico and Guatemala.

Scientists have long thought that severe drought caused its collapse.

But Mexican and British researchers now think that a sustained drop in rainfall of only 25-40% was enough to exhaust seasonal water supplies in the region.

The findings were published in the journal Science.

The research was conducted by the Yucatan Centre for Scientific Research in southern Mexico and the University of Southampton in the UK.

The second piece published by the BBC within 24 hours went as follows,

Drought conditions in England ‘set to widen’

Ongoing dry weather over the spring and summer threatens to place more areas of England in a state of drought, the Environment Agency (EA) has warned.

It singled out parts of western, central and south western England and parts of south east Yorkshire.

The agency said time was running out for rain to restore groundwater levels before the new growing season begins.

Earlier this week the South East joined most of East Anglia in a state of official drought.

In parts of south-east England groundwater levels are lower than in the infamously dry summer of 1976.

And closer to home?

The historical (30-year average) precipitation for Payson up here in the Rim Country is 2.30 inches for January, and 2.41 inches for February.  Today, February 29th 2012, we have had less than 0.5 inches for the whole of 2012 so far!  Interesting times!

British Otters

A wonderful ‘good news’ story.

Just a few days ago, the British news media carried a wonderful story about the resurgence of the otter in every county of England.  For many years, the otter was losing the battle for survival owing to hunting and trapping and the far South-West of England became it’s last refuge.

Then a combination of sensible legislation and public commitment to saving the otter became the turning point.

Here’s a typical media report from The Independent newspaper of Thursday, 18th August,

Otters return to every county in England

Once the rivers were cleaned up, fish returned to once-polluted waters and otters began to spread back eastwards from their strongholds in Devon and Wales

By Michael McCarthy, Environment Editor

It has taken 30 years, but the otter’s comeback is now complete. After becoming extinct across most of England in the Fifties and Sixties, one of Britain’s best-loved animals has now returned to every English county, the Environment Agency announced yesterday.

The slow but steady recolonisation of its former haunts has been rounded off with the reappearance of otters in Kent, the last county to have been without them, the agency said.

The otter’s return represents a happy ending to one of the worst episodes in modern British wildlife history: the sudden disappearance of one of our most widespread and charismatic mammals.

The process began around 1956 and was almost certainly caused by the introduction of powerful organochlorine pesticides such as aldrin and dieldrin. Residues of these chemicals were washed into the rivers where otters lived, poisoning them.

As wild otters are hard to spot – their presence is usually detected by their spraints, or droppings – it was several years before the scale of their disappearance began to dawn on people, but by then they had been wiped out over vast areas of lowland England.

Despite the banning of organochlorine pesticides in the mid-Sixties, otters continued to decline, and their population reached a low point by the end of the 1970s, when they had effectively vanished from everywhere except the West Country and parts of Northern England (although good numbers remained in Wales and Scotland).

The first national otter survey, carried out between 1977 and 1979, detected the presence of otters in just over 5 per cent of the 2,940 sites surveyed; all the sites were known to have held the animals previously.

But then a comeback gradually began. Helped by a substantial clean-up of England’s rivers, which brought back fish to many once-polluted watercourses, and by legal protection, otters began to spread back eastwards into England from their strongholds in Devon and in areas of the Welsh borders, such as the Wye Valley.

By the time of the fourth otter survey, carried out between 2000 and 2002, more than 36 per cent of the sites examined showed otter traces; and when the fifth survey was carried out, between 2009 and 2010, the figure had risen to nearly 60 per cent, with otters back in every English county except Kent. Now wildlife experts at the Environment Agency have confirmed that there are at least two otters in Kent, which have built their holts on the River Medway and the River Eden.

“The recovery of otters from near-extinction shows how far we’ve come in controlling pollution and improving water quality,” said Alastair Driver, the Environment Agency’s National Conservation Manager. “Rivers in England are the healthiest for over 20 years, and otters, salmon and other wildlife are returning to many rivers for the first time since the industrial revolution.

“The fact that otters are now returning to Kent is the final piece in the jigsaw for otter recovery in England and is a symbol of great success for everybody involved in otter conservation.”

Otters are at the top of the food chain, and are therefore an important indicator of river health. The clean-up means that they are now inhabiting once-polluted rivers running through cities – something which would have been unthinkable before the population crash – and they have been detected in places such as Stoke-on-Trent, Reading, Exeter and Leeds, as well as in more likely urban centres, such as Winchester.

But although they are now widespread once more, otters’ nocturnal habits and riverine habitat make them difficult to glimpse, let alone observe, in England. The best place to see otters in Britain is Western Scotland, where the animals have become semi-marine and live along the coast. They can regularly be seen foraging along the shoreline in the daytime, especially on some of the larger islands, such as Mull and Skye.

 A lovely story with a powerful message – mankind can change things for the better, and frequently has done.
Representing the power of positive change!
