Are hedgerows priority habitats?

Hedgerows are a widespread Priority Habitat (i.e. a habitat of principal importance for biodiversity conservation), providing key semi-natural habitat for a broad range of biodiversity, including many threatened species. They occur predominantly in lowland farmland but also in urban areas.

Is a hedgerow a habitat?

Hedgerows are one of our most easily encountered wildlife habitats, found lining roads, railways and footpaths, bordering fields and gardens and on the coast.

How do hedgerows benefit wildlife?

Hedgerows provide food and shelter for insects, birds and other animals, forming corridors that permit wildlife to move between habitats. As many birds and small mammals never venture more than a few metres from cover, populations would become isolated and vulnerable without hedges.

How does the removal of hedgerows affect biodiversity?

Hedgerow removal can lead to the loss of important connections within the landscape for commuting bats and also a reduction in insect diversity and hence foraging opportunities. Management of hedgerows for bats should aim to produce tall (ideally a minimum of 3m), wide and continuous hedges, comprising native species.

Does hedge laying increase biodiversity?

Hedgerows provide habitat for a range of invertebrates from butterflies to spiders. … It also found that hedge laying can increase provide a diverse range and high abundance of invertebrates as the hedge grows.

What animals live in a hedgerow habitat?

Predators, such as Long-eared Owls and foxes visit hedgerows to feed on small mammals and young birds. The Long-eared Owl (Ceann Cait) is a nocturnal, predatory bird that hunts a wide range of small mammals, including mice, rats and shrews.

Is it illegal to remove a hedgerow?

Removing a hedgerow is a criminal offence which can lead to potentially unlimited fines if the breach is deemed serious enough to be heard in the Crown Court.

How do hedgerows improve the environment?

Hedgerows reduce the amount of polluting fertilisers, pesticides and sediment that reach watercourses through acting as a physical barrier, through increasing infiltration into the ground, and through nutrients being recycled by the trees, shrubs and other plants.

Why is maintaining hedgerows a good thing for the environment?

Hedgerows are important for farmland wildlife. They provide a variety of resources for species that benefit crops, including shelter for predators of crop pests and food for bees and other insects that pollinate crops3. They are especially vital for wintering birds1.

What value and benefits do hedgerows have to wildlife in the Irish countryside?

Hedgerows give the Irish landscape its distinctive character and field pattern. They provide an important wildlife habitat especially for woodland flora and fauna. Increasing the variety of hedgerow types in terms of height, width, shape and species mix promotes diversity in flora and fauna.

What is the importance of hedgerows in farming?

Benefits of a hedgerow

Hedgerows can help control insect pests as predatory insects overwinter in them and move into the crops in spring when aphid numbers start to increase. They also act as barriers to windborne pests, and insects in the hedgerow pollinate crops, particularly bumblebees, which need hedge banks.

Why are field margins and hedgerows are important in maintaining biodiversity?

Field margins can help buffer hedgerows and ditches from farm operations, and a diversity of habitats in close proximity will have wildlife benefits, providing a greater range of food resources, shelter and breeding habitats, especially benefitting less mobile species. Corners of fields can be particularly valuable.

Why are hedgerows so important?

Hedgerows provide food and shelter for many species. Because they often link small woods, they are essential corridors along which wildlife can travel.

How does reintroduction of field margins and hedgerows maintain biodiversity?

Conservation headlands, beetlebanks and grass margins around arable fields are all kept free of pesticides so that invertebrates can thrive. Insects living in these strips may include crop pollinators and predators of crop pests, and are also a food source for birds and small mammals.

What are hedgerows in agriculture?

Hedgerows give the Irish landscape its distinctive character and field pattern. They provide an important wildlife habitat especially for woodland flora and fauna. Increasing the variety of hedgerow types in terms of height, width, shape and species mix promotes diversity in flora and fauna.

What makes a species rich hedgerow?

The UK Habitat Action Plan for species-rich hedgerows defines them as hedges “which contain five or more native woody species in a 30 metre length”. Hedges that contain less than 5 woody species (trees and shrubs) in each 30m, but have a rich variety of herbaceous plants at their base, are also included.
