Rain cows

This year anyone could be forgiven for thinking it's raining cows, not just cats and dogs. Yesterday I set off under a steady drizzle to check our conservation grazing herd on the Common. This involves walking the fence line of three separate meadows to confirm it's all intact - we don't want cows escaping onto nearby roads - as well as counting the cattle in each area and making sure they're all in good health, and checking their troughs are full.

The cows displayed a bovine indifference to rain. Their coats have an oily waterproof sheen and water falling from the sky wasn't going to deter them from eating and digesting the green riches around them. This is a 24-hour a day job for them and their dedication to it is admirable. Perhaps if I stop washing my hair, it too will develop a waterproof layer of oil, but friends and family might complain about the smell...

Under the rain, which grew steadily heavier over the next two-and-a-half hours, I viewed the countryside as a green smudge around me, with somewhat blurry edges. A bit like some of my photographs, but bear with me, it was raining, the cows were moving, and I was desperately trying to keep my camera dry.

Despite the weather, I felt a deep contentment. The rain had driven away all other human disturbances - even the dog-walkers had gone home - and I had the Common and it's wildlife all to myself. Incredibly, a few butterflies were on the wing: brown ringlets. Later I read, in a doom-laden article about butterflies in trouble in this wettest of summers, that ringlets (and speckled woods) like damp conditions.

In Rye Meadow, my favourite piece of pasture, I spotted a roebuck lying beside the electric fence right out in the open. As I approached like a child playing grandmother's footsteps, I began to fear that its determination to stay put was a sign of injury, but at the last moment it bounded away.

This part of the Common resisted the plough during the wartime "dig for victory" campaign, unlike our main grazing area, and it has retained a diverse seedbank of wildflowers, rushes, sedges and grasses. It was cleared of secondary woodland just two to three years ago and, with sunlight striking the ground again for the first time in decades, the seeds germinated. Yesterday I found water figwort and betony in flower.

I didn't notice how wet and tired I was until I got home...
















ps We don't normally give our cows names but Blondie seemed an obvious choice for the only white one. They belong to a local farmer and are destined for the table eventually. At least they enjoy one of the best summers a cow could wish for on the Common. And as dairy steers, most of their peers are killed at birth: males don't give milk and their breeding makes their muscles unsuited for prime cuts.

Kaleidoscope fritillaries

Marsh Fritillary - male


















Finglandrigg Wood sounds like a setting from Lord of the Rings or one of the Icelandic sagas, but the reality is even more magical. It is among four sites chosen in Cumbria to re-introduce the marsh fritillary butterfly after it reached the brink of extinction in the county around the millenium. I made a round trip of 100 miles to reach it from our Lakeland cottage.

“Kaleidoscope” is one of several collective nouns for butterflies but it suits the marsh fritillary perfectly. Its latin name, Euphydryas aurinia, roughly translates as “golden floating checkerspot”.

The site, managed by Natural England, has a magic of its own. In the lay-by where I parked, I bumped into another butterfly enthusiast from Norfolk (again!), who explained in detail the mile-long trail I needed to follow to find the butterflies and assured me they were flying in dozens and much easier to photograph than the elusive mountain ringlets. With my hopeless sense of direction, I might easily have missed them altogether without his instructions, despite the helpful butterfly waymarks.




















With rising anticipation, like a child on Christmas Eve, I walked first through dappled woodland, across a stream humming with damsels and dragons, through a gate into boggy heathland dotted with grazing cattle. There was a sign warning of adders and I thought to myself, “Can it get any better?” but sadly it was already too warm for basking reptiles. Then I came to a buttercup meadow, a splash of gleaming yellow in the sun, possibly the most splendid buttercup meadow I’ve ever seen.

Beyond that another field, damp grassland and suddenly the kaleidoscope started spinning. The word “fritillary” comes from the latin “fritillus” – dice box. Romans kept their dice in boxes with an inlaid chequered pattern, just like the wings of the butterflies named after them.

The Marsh fritillaries flitted from one clump of damp grass to another, undefeated by a strong gusting breeze in their mission to find a mate. The foodplant of their larvae is devil’s bit scabious, not yet in flower when I visited in late May.  In summer the black caterpillars live gregariously on webs spun across it. When I stopped in nearby Kirkhampton to buy some lunch, the shopkeeper told me that local children had been planting devil’s bit scabious for the butterflies – “to help them come back”.















After a few photographs, I sat down in the damp grass to marvel at the marsh fritillaries’ checkerboard orange, almost red and creamy yellow wings, separated by a fat furry body. A mating pair landed on a tussock beside me – the male larger with broadly open wings, the female fluttering her wings closed from time to time. The male walked them, oblivious, onto my hand.

The story of their reintroduction to Cumbria is worth retelling, though you can find it in more detail on the website of Butterfly Conservation’s Cumbria Branch. At one time there were some 200 colonies of marsh fritillary in Cumbria but by the year 2000 they had dwindled to three and four years later were facing extinction in the county. The situation continued to worsen despite attempts to manage their habitats carefully to suit their needs. Conservationists found just one egg batch on the last site in 2004.

The Cumbria Marsh Fritillary Action Group brought together decision makers from Butterfly Conservation, Natural England and Defra, and thanks to a very supportive individual at Natural England gained a licence within a single day to take the last 150 larvae into captivity. Several reasons for the drastic decline were considered: loss of habitat as marginal land was brought into farming production, too much shading from trees on field edges, parasitic wasps which attack the caterpillars in waxing and waning cycles, and genetic weakness in the isolated and tiny colony.

Three batches of larvae were raised in captivity, one pure Cumbrian, one from colonies in Argyll and one a mixture of the two. The results suggested that genetic weakness was the problem as none of the pure Cumbrian stock successfully emerged as adults. By 2007 45,000 caterpillars of mixed Scottish and Cumbrian heritage had been reared and four sites were prepared for their release. Butterfly conservationists learnt a great deal from the process.

Finglandrigg, 13 km west of Carlisle on the Solway plain, is the only site open to the public, and what a site it is – not just for the fritillaries. It also counts red squirrels, brown hares, badgers, otters, roe deer, many species of dragon and damselflies and warblers among its residents.

Needless to say, the marsh fritillary is one of the UK’s fastest declining butterflies, though it is also found in Argyll, the west coast of Ireland and Wales and the English Westcountry. But the success of the Cumbrian reintroduction shows just how much a handful of dedicated naturalists can achieve. I owe them a debt of thanks: they made my heart soar.
