Comparing a map of 1920 with today, we can see that approximately 1km of hedging has either been removed or replaced with wire in the last 100 or so years on the 16 acres which comprise Tymawr farm. If we assume that the width of these hedges including any associated ditches was approximately 3 metres, three-quarters of an acre of rich wildlife habitat has been lost in that time.
Hedges
wonderfully illustrate the main principles of the way that we want to farm
Tymawr in the future: They are productive, permanent, polycultural and
aesthetically pleasing: They provide habitat and sustenance for wildlife; food,
fuel and timber for the farm; their
combination of shrubs, trees and weeds improves the soil; used together with
ditches they help to drain and improve otherwise unproductive pasture; they
provide a shelter in extreme weather for farm animals; finally, they act as a
stock-proof barrier. This is a great
illustration of the Lean-Passive farming model which we want to create. Compare this with a wire fence which has largely replaced the hedge– it is
stock-proof certainly, but provides none of the other advantages of a hedge:
Wire fences illustrate nearly everything which is wrong with conventional
farming: They are single-purpose, they
provide no ongoing financial contribution to the farm, they wastefully use
valuable resources, they contribute nothing to the improvement of the soil, the
stock, the indigenous wildlife or the farm; they are ugly!
Over a period of years we aim to rehabilitate Tymawr Farm, with projects including: hedge planting & restoration, creation of a forest garden, drainage and water management projects including improvement of the brook and creation of new ponds, traditional cider orchard creation and the establishment of pedigree herds of local, primitive and unimproved breeds of pig, cattle, sheep and poultry. With these ambitious goals in mind, a great starting point, achievable in a relatively short period of time, is the restoration of the first 100 metres of hedge, including re-establishing the 1920 route of the hedge which followed the contour of the land in the traditional manner, this meandering route was replaced by a 'rational' straight line in the 1970s.
This incredibly diverse polyculture exists within a wide range of microclimates, from sunny, sheltered and dry, to shaded, exposed and wet, with every permutation and combination inbetween. These microclimates, partly created by aspect, soil, microtopology and partly by the hedge itself, create an ever changing habitat, supporting a wide range of wildlife and plants in a compact area. It is not uncommon to find 4 or 5 distinct microclimates in 10 metres of hedge.
This combination of plant species and microclimate in turn attracts, nurtures and supports a surprisingly wide range of wildlife. Generally, birds nest in the "overstorey" and "canopy" layers, feeding on fruits and insects; insects including bees and lepidoptera feed on the pollen and nectar produced by the tree blossom and flowers; small mammals feed and shelter in the dense hedge base; larger mammals use the hedge as a "corridor" to allow them to pass from their sleeping area to feeding and mating areas unseen; predators use the cover provided by the hedge to lie in wait for their prey.
The soil and the wildlife are not the only potential beneficiaries of the hedge; the farm benefits in a really tangible way too; country wines, syrups, preserves and port and gin-adulterants are made from the hedge-fruits and flowers, the Hazel contributes bean-stakes and charcoal-faggots, "canopy" layer trees contribute firewood and timber, nuts and mast from the Hazel and Beech contribute protein-rich human and pig food, holly and mistletoe can be made into festive wreaths and kissing-encouragers, numerous herbs and salad crops from the "ground" layer put food on the table throughout the year. The hedge pays its way.
