A severe drought in Kenya is putting giraffes, zebras and other animals at extreme risk. Can you help get water and food to these starving animals? Find out more here or donate to help the grazing wildlife here.

What have hedgerows ever done for us?

We are interested in hedgerows because they are home to animals and provide habitat connection corridors meaning that wildlife can move around the landscape.

However, they also deliver a number of additional benefits to farmland, beyond that of a field boundary.

Here’s a list of some of the amazing things hedgerows do for us:

Hedgerows provide shelter for livestock

cows shelter from sun in shade of hedgerows and trees

  • Livestock on farms without shelter have a higher mortality and require more food
  • Shelter can increase lamb survival rates by reducing the effect of wind chill and thus hypothermia 
  • In the summer months, heat stress can reduce milk yield in dairy herds

Hedgerows regulate water supply for crops by:

  • reducing water loss through evaporation by decreasing wind speed over the ground surface
  • helping to store water for later use – a 50m hedgerow at the bottom of a 1ha field can store between 150 and 375 cubic metres of water during rainy periods for slow release down slopes during dry periods
  • reducing flooding by increasing the rate of water infiltration and slowing flows of water. Their deep roots help them remove water faster from the soil than crops during periods of excessive rainfall.

Animal health can be improved

  • Reductions in damp conditions in fields may reduce incidence rates of lameness

Shelter creates warmer soils, extending the growing season

Hedgerows reduce soil erosion

  • by reducing surface wind speeds; and
  • acting as a barrier to water-borne run-off

Hedgerows can reduce the need for pesticide use

  • They increase populations of predator species; and natural enemies of pests can improve the potential for biological control, so reducing the need for farmer input or pesticide use.
  • Biological control is a service provided by species of farmland birds and predatory invertebrates, such as spiders and predatory beetles, as these groups feed on, and therefore limit the populations of, pest species.
  • Rich flora in a hedge base will attract a host of predatory and parasitic species able to tackle crop pests

Hedgerows help sustain pollinator communities which support productive farming

  • Pollination services are valued at £430 – £603 million annually
  • Managed honey bees are an essential part of pollination, but populations are currently vulnerable to disease and pesticide usage, making populations of wild pollinators increasingly important. 
  • Bees and other pollinators depend on forage throughout the year including when crops are not in flower

A sustainable source of wood fuel

  • Hedges and hedgerow trees can provide sustainable wood fuel if managed correctly. Pollarding is a traditional management of trees that can provide both wood fuel and animal fodder.

Wildlife-friendly farms have reduced risk of bTB in cattle herds

  • Hedgerows appear to be a key factor for improved biosecurity. ‘Hedge-poor’ farms, those with few hedgerows and large field sizes, were found to have greater risk of bTB outbreaks than ‘hedge-rich’ farms.
  • Hedgerow availability, width and continuity has also shown to be to be more important than badger abundance in affecting bTB incidence.

Hedgerows can have a role in reducing the rate of climate change through carbon storage

  • A new hedgerow may store 600 – 800 kg of carbon per year per 1000m, for up to 20 years 

Hedgerows reduce pollution

  • by reducing the amount of fertilisers, pesticides and sediment that reach watercourses.
  • They do this by acting as a physical barrier, increasing infiltration into the ground, and through nutrients being recycled by the trees, shrubs and other plants.
