PhD student Pip Jones is taking the model ewes' temperatures as she moves them around the fields of Bangor University's research farm, comparing places where trees, hedgerows and shelter belts
are grown with areas where there is no shelter.
Wind Breaks and Shelter Belts
: Any barrier which slow down the speed and effect of wind is known as a wind break.
She said developing and applying water management techniques like desalination, saving and reusing treated water, fixating soils through the use of sand fences, shelter belts
, woodlots and windbreaks, enabling native tree growth through selective pruning of shrub shoots and enriching soil through plantation, can help in this regard.
NEW shelter belts
and hedgerows at Pontbren Farming Group, near Llanfair Caereinion, have helped slow peak water run-offs into rivers by as much as 40%.
"When we left Hong Kong in 2000 we realised we had a field at the back of our house that had a pretty perfect microclimate." Sitting next to Snitterfield Fruit Farm, the south-facing slope is surrounded by shelter belts

Oak, ash and birch trees, and shrubs such as crab-apple, spindle and guelder rose, were planted on two of the estate's tenanted farms to create a number of shelter belts
most of the efforts at tree conservation in those Western states are aimed at shelter belts

It's a delightful and effective tribute to the many abandoned pieces of iron now residing in shelter belts

The key to its success lies in shelter belts
. The deep woodland that surrounds the garden makes a wonderful backdrop, but their real function is to protect the garden from scouring gales.

Various types of wind barriers and shelter belts
