Most of the land around Greenhillock has been intensively farmed for decades. To increase yields, field margins have been ploughed up and trees and hedges removed. It is estimated that we have lost some 500,000 kms of hedgerow in the UK in the past 60 years. In this blog, I hope to tell you why this is important and about our modest efforts to combat this trend. Very recently, farming subsidies have encouraged more sustainable practices and we look forward, in time, to the restoration of a better balanced landscape.
Trees and hedges add three important dimensions to any habitat – food, cover and shelter – and the protection provided by hedgerow bases is important in the survival of native wildflowers, grasses and plantains which, in turn support a community of invertebrates and birds. If you pitch your tent on a windy day you too will appreciate the considerable sheltering effect of our 3-4 metre high perimeter hedges!
With the exception of the 150+ year old Beech trees on the East boundary, all of the trees and hedges on site were planted by us and our neighbour Mary. Nearly all are native species (with a few other trees gifted to us in ways that obliged us to plant them) and there are well over 20 varieties – an interesting identification challenge for visitors. The hedges are 90% thorn (Hawthorn, Blackthorn and Wild Rose) inter-planted with Oak, Ash, Rowan, Hazel, Beech, Field Maple, Alder, Holly, Bird Cherry and other species. These provide food in the form of pollen and nectar in Spring and Summer and berries in Autumn and Winter. The thick spiny interior gives important protection from predators for nesting birds and an escape for small birds from the attentions of raptors such as Sparrowhawk, Kestrel and Buzzard.
Finally, connecting up areas of woodland with ponds and other habitat essentials, hedges serve as ‘wildlife corridors’, allowing birds and animals to move safely through their respective territories. As well as many types of bird, over the years, we have seen Roe Deer, Foxes, Badgers, Stoats, Rabbits, Red Squirrels, Brown Hares and even Otter, all making use of this feature. So please don’t take trees and hedges for granted – the world would be a poorer place without them!
