Last summer, on one of the hottest days of the year, I joined a walk led by Nick Gray of the Dorset Wildlife Trust through some traditionally managed meadows in Dorset’s western Vale. We found fields filled with lush grasses, colourful wildflowers and a profusion of insects. This outpouring of joyous, exuberant growth seemed to embody the essence of high summer and the walk turned out to be one of my wildlife highlights of 2018.
We started from Babers Farm below the village of Marshwood and, after a short walk across several fields clad only in a veneer of golden stubble, we crossed a field boundary to enter another world. Here a thick carpet of knee-high grasses dominated the sward, still green despite the long spell of hot weather. Richly coloured flowers were woven into the grassy fabric and many small brown butterflies danced among the seed heads. A transient flash of orange was probably a silver-washed fritillary butterfly. Grasshoppers leapt from the grass in broad arcs as we walked and brightly coloured insects fed from the flowers. As I looked up at the bowl of hills surrounding the Vale, a kestrel, pale brown in this brash light, swept silently across the field. It was the perfect summer moment.
Perhaps it was a reaction to all the doom and gloom I had been hearing about our treatment of the environment and the resulting loss of wildlife? Perhaps it was a deeply buried childhood memory of family picnics among flowers on Dorset hills? Perhaps it was simply all the natural beauty around me? Whatever the reason, it felt, for a few moments, as though this was the only place in the world I wanted to be.
These meadows are managed under a higher-level stewardship scheme which pays for the loss of income incurred through traditional, less intensive land cultivation. The meadow flowers and grasses grow during the warmth and wet of spring and summer and hay is cut and removed in mid-July when flowers have mostly set seed. The aftermath growth is grazed by animals in the autumn after which the land is left until the following spring. It was the last day of June when we visited and high summer sees these meadows liberally studded with the flattened white umbels of corky-fruited water dropwort, a member of the carrot family and a Dorset speciality but rare elsewhere. The flowers were very popular with insects, especially hoverflies which buzzed loudly in small groups while hovering by the flowers in a courtship display. A female would sit on a flower head while a male hovered above her; sometimes another male would hover above the first in a “stack”.
The bright yellow slipper-like flowers of bird’s foot trefoil were also very common in the meadows, sometimes growing so prolifically that the flowers merged into drifts of sunny colour. This is such a common flower that we tend to overlook it but perhaps its very familiarity leads to the many popular names attached to the plant such as eggs and bacon, hen and chickens or granny’s toenails. Nick also told us that the plant may have useful anti-worming properties if consumed by sheep.
Dotted around the meadows, sometimes in large clumps, were the unruly purple flowers of knapweed. These are popular with nectaring insects and I saw a colourful burnet moth and several marbled white butterflies. Knapweed is also one of the plants with the popular name of Bachelor’s Buttons and Nick told us how, in the past, young women played a love-divination game with the flower heads. A young woman wanting to know if her affections would be returned took a knapweed flower head and plucked off the open florets. She placed the flower head inside her blouse and if, after an hour, new florets had opened, then her love would be reciprocated.
Here is the story told by John Clare in his poem May from the Shepherd’s Calendar:
They pull the little blossom threads
From out the knapweeds button heads
And put the husk wi many a smile
In their white bosoms for awhile
Who if they guess aright the swain
That loves sweet fancys trys to gain
Tis said that ere its lain an hour
Twill blossom wi a second flower
And from her white breasts hankerchief
Bloom as they ne’er had lost a leaf
A short walk across open countryside took us southwards towards the centre of the Vale, where we found another large traditionally managed meadow. As before, a rich mixture of thick grasses and colourful flowers dominated but I was surprised to find drifts of yellow rattle and a few orchids, looking rather the worse for wear. I began to realise that each meadow has its own character, its own flora, its own colours reflecting the underlying geology and dampness.
Several recent studies have highlighted the decline of insect and bird life in the UK. Factors contributing to this decline include climate change, habitat loss, pollution and pesticide use. For example, the 97% loss of flower-rich hay meadows in the UK during the 20th century linked to agricultural intensification must have seriously affected insect populations as well as birds dependent on insects for food. Some have gone so far as to suggest that unless we modify farming methods, we shall face “Insect Armageddon”. This needs to be taken seriously owing to the important role insects play in, for example, maintaining soil health, digesting waste and pollinating our fruit and flowers.
The meadows that I visited last summer in the Marshwood Vale send a positive message showing that, with careful management, these important habitats can be restored to their former glory, supporting insects and providing food for birds. In more good news, the Magical Marshwood Vale Project (funded by National Grid and coordinated by Dorset AONB and Dorset Wildlife Trust) started in 2018 with the aim of enhancing traditional landscape features and helping to reinstate ecologically important wildlife habitats. This includes the restoration of more wildflower meadows.
I should like to thank Nick Gray for his advice and enthusiasm.
