Farmland Habitats
Farming shaped our lowland landscape. For
centuries, hedgerows and arable land have been important
habitats for wildlife. But the recent shift to livestock
farming threatens this harmony.
Hedgerows
Hedgerows are part and parcel of the Welsh countryside. They are
important for landscape, cultural, archaeological and agricultural
reasons.
But these threads of shrubs and trees are also important for
wildlife. They provide refuge and resources for native flora and
fauna in the middle of a continuous swathes of grassland. Records
show that over 600 plant, 1500 insect, 65 bird and 20 mammal
species live or feed in hedgerows. And these green boundaries are a
primary habitat for at least 47 Species of Conservation Concern in
the UK.
Arable Land
Ever since mankind first cultivated the land to grow crops, many
species of plants and animals have taken advantage of these
manmade habitats.
Many specialist annual plants depend on the bare soil that
cultivation creates. A range of invertebrates and small
mammals, as well as several species of nesting and over-wintering
birds, make use of the crop and arable weeds for shelter and
food.
But over the last few decades, as farms specialise more in
livestock, arable farming has virtually disappeared in many areas
of Wales. Meanwhile, intensification has reduced the wildlife
value of remaining arable land. As a result, many species of
arable weed are now rare and the farmland birds that depend on
mixed farming are in decline.
