Country Park 2011

Dead and desiccated juvenile common newt, from our garden pond.

Buzzard

Male chaffinch

Otter spraint under the concrete bridge.

Tons of spawn!
.
I'll be keeping a very close eye on Greenfields Nature Reserve (the country park) this year because last summer the water voles here disappeared due to mink predation. I have no idea whether either mink or voles will return. There are no signs of either yet, though there's plenty of otter spraint under the bridge.
.
There are also dozens of active frogs in the pond created a couple of years ago by the Whitchurch Water Vole Group and, along with the frogs, bucketfuls of spawn.

An Old Friend, and an Opportunity

The blackbird that lives by White Lion Meadow (Tesco)
.
Fresh water vole droppings in the ditch by Grocontinental.
.

Field vole droppings for comparison. Teeny weeny, smaller than uncooked grains of rice.
.
Water vole foot prints in the ditch by Grocontinental.
.
A feeding station further up - could be field- or water-vole.
.
Rubbish finding its way from the yard of one of the industrial units
.

What's this pipe been discharging into the water?
.

Unsuitable habitat - too many trees shading the soil.
.
Checked on the ditch near Grocontinental and found more prints at one end and fresh droppings at the other, so it looks as though these water voles are establishing themselves well again this year. Then I followed the ditch further, crossing Grocontinental's yard, to investigate an area I'd not seen before. The first stretch looks like potentially good habitat as a lot of predators will be discouraged by the noise from the industrial units on either side, and at the moment the water level here stays pretty regular (though it may not do if a lot of new units get built - Shropshire Planning Dept need to be aware of this re application ref 11/00806/FUL ).
.
However, further up the water is contaminated with rubbish from one of the units, and then towards the culverted end there are too many trees to allow much vegetation to grow on the banks. The habitat could be improved by felling some of the trees to let more light in, and asking the owners of the industrial units to take more care in how they dispose of their rubbish.
.
An opportunity to extend and strengthen a water vole colony here!

When Voles Grow Wings

Moves like a vole, is brown as a vole, but isn't a vole.

The ditch near Grocontinental, featuring...

...a latrine by the bridge
I'm sure these are water vole prints and not rat - White Lion Meadow
.
It's still too cold to go out watching for water voles, but the evening was so nice I couldn't stay indoors so went in search of field signs. There are water vole footprints at White Lion Meadow (near Tesco), another latrine in the ditch by Grocontinental, and new burrows at Edward German Drive and the field off Edgeley Road.
.
Thought I'd had my first sighting of the year! - but it turned out to be this wren. I can't tell you how many times I've confused wrens and voles, given they're often found in the same location and creep about in the same way. I've even seen wrens come out of vole holes. Most annoying.

Putting out the Welcome Mat

Construction going on in the same field as the water voles. Council planners have stipulated the work must not come any closer to the bank than ten metres.
.
Ditch with piece of wood thrown in.

But closer inspection of the plank reveals a latrine. It's always worth checking floating junk if you think water voles might be in the vicinity.
.
Water vole footprints further down the ditch, towards Grocontinental
.
It's helpful when the first latrines appear, because colonies don't always stay in the same place from year to year so it can take a few weeks for me to work out where best to set up my camera. And there's no surer sign of water vole activity than droppings - it's like the animal's putting out its front door mat.
.
The water voles in the field near Grocontinental seem to wake up earlier than the ones just across the railway line, so there are three latrines in this ditch already and I'm hoping to get my first vole sighting here next month. However, Grocontinental are busy with some building work not far away, so I hope the brook stays uncontaminated and undisturbed.

Des Ong's Lovely Voles


Active already, apparently! For more gorgeous water vole photos, go to desong.co.uk

Anxious Year Ahead

One of the frogs in my pond gearing up to breed.

This should be a happy time - first proper field signs appearing, and spring getting ready to unfurl. But this year will be the one where the council decides whether to re-designate two wildlife-important fields from their current 'green space' status to 'for development'. It shouldn't even be a consideration.
.
Because not only does this have catastrophic implications for the water voles, it's extremely serious for the people of the town, too.
.
Currently this very marshy land soaks up water like a giant sponge. It's a natural storage or holding tank for the surrounding area. However, if these fields were to be drained and concreted over, and additional water from new household or industrial use added to our natural, often torrential levels of rainfall, the likelihood of many Whitchurch homes flooding looks like a cert.
.
And anyway, what developer would want to go to all the expense and time of getting in ecological experts to assess the land, trap all the voles, keep the voles safe while the houses are built, have ecological experts guide the developer to reinstate the water course to a standard where it was suitable for the voles to return? Which of course would have to be done by law.
.
I absolutely can't imagine a less suitable place for building. So you have to hope commonsense prevails here!

Reading the banks

Field off Edgeley Road, location of burrow/slipway photos below.

Erosion reveals this old burrow in horizontal cross section.


Slipways or trackways running into the water from burrows.


Occupied burrow

Droppings at the railway bridge by Homebase, but are they rat or w-v? Both animals tend to make use of this handy brick!
.

Still a few weeks too early for real signs to emerge, I'd have thought, though a fortnight of days as warm as today would wake the water voles up I'm sure. But even in the absence of breeding latrines and ostentatious feeding stations it's not too hard to see where the w-vs have been active. There are occupied burrows, for instance, with nibbled grass round the outsides, and lots of slipways into the water. Have to say, though, these don't always come out so clearly in photographs; they're actually more obvious in the field.
