26

What is the purpose of a SAC?

To provide rare and vulnerable wildlife and habitats with increased protection and management.
- E.g. Dartmoor

27

What are the global and local aims of DEFRA?

- Sustainable rural communities
- Sustainable farming and food sector (animal health and welfare)

28

What is the purpose of a Ramsar Site?

To protect wetlands of international importance and ensuring sustainable use of wetlands.
- E.g. Minsmere, Suffolk

29

What are the three main plans of the UK BAP?

- Species Action Plan (382 threatened species)
- Habitat Action Plan (28 habitats)
- Local Action Plan (individual counties)

30

What are the aims of the Environmental Stewardship Scheme?

- Conserve wildlife
- Maintain/enhance landscape quality
- Protect historic environments
- Promote public access and understanding
- Protect natural resources

31

What are the features of farm management that are awarded points in the ESS and the benefits of them?

- Hedgerow/Stone wall/Ditch management (maintain landscape)
- Field buffer strips (protect rivers)
- Wild bird seeds (winter bird food)
- Low input grasslands (protect wildflowers)
- Archaeological sites (protection)
- Reduce soil erosion (maintain production/protect rivers)
- In-field tree protection (wildlife habitat)
- Beetle banks (habitat for natural predators/reduce pesticide use)

32

What campaigns does WWF perform?

35

How have woodlands been traditionally managed?

- Mature Trees (Produce large timbers for housing)
- Coppicing (Cut to ground level every 7-12 years)
- Pollarding (Cut down to 1.8m to protect new growth from grazing)

36

Why are native woodlands important?

- Terrestrial habitat with high biodiversity
- Possible range of recreational activities
- Regulates water flow in catchment areas
- Trees reduce soil erosion
- Absorb carbon dioxide, limit global climate change
- Return water to atmosphere (evapotranspiration)
- Provide sustainable supply of fuel
- Timber (construction, tools, ship building)

37

What are the threats to wetlands?

- Drainage to produce productive farmland
- Urban expansions onto flood plains
- River straightening to reduce flooding risk
- Excessive recreation pressure
- Bank reinforcement to reduce flooding risk
- Pollution (industry, sewage and agriculture)

38

What are the threats to The Broads?

- Traditional crafts have declined (cutting reeds for roof thatching)
- Eutrophication decline natural foodwebs (growth of algae)
- Introduced species (Coypu damage banks and cause floods)
- Recreation pressure (litter, noise, trampling and fuel pollution)
- Global climate change cause flooding and saltwater incursions

39

What are the management strategies to prevent the threats to The Broads?

- Sediment removal (remove phosphates)
- Phosphate removal from liquid effluents
- Coypu eradication
- Reed bed clearance and the re-establishment of commercial reed cutting
- Bank protection
- Speed limits for boats
- Path maintenance
- Public education

40

What are the threats to Lowland Heathlands?

42

What are the reasons for hedgerow loss?

- Increase in size of arable fields (easier use of machinery)
- Increase in farmable areas (food harvests)
- Road widening
- Replacement by fences
- Damage by vehicles
- Neglecting traditional managements

43

What are the threats to the environment through loss of hedgerows?
