- Threatened Habitats in the UK
- Lowland Heathland
- Plagioclimax habitat usually found on sand & gravel soils. Soils infertile = not been intensively farmed. Low use of fertilisers & pesticides = many wildlife species. Grazing/burning prevent woodland re-establishment= smaller plants such as heather & gorge
- Threats
- urban expansion
- golf courses
- stopping use of burning
- conifer plantations
- Hedgerows
- Types: Woodland relic hedges - strips of woodland left between fields as woodland was cleared. Rich in plant- life = rich in animal life. Planted hedges - to divide up common land/barriers to keep livestock in. less plant/animals so lower wildlife value
- Reasons for loss
- increase in size of fields
- road widening
- replacement by fences cause easier to maintain
- Chalk Grassland
- Arable farming led to soil erosion, meant crop growing stopped. Used for sheep grazing which prevented woodland.
- Threats
- intensive farming with use of fertilisers cause infertile soil
- urban expansion/road building
- Hay Meadows
- Threats
- silage cutting - cutting during summer - destroys nests
- Threats
- Upland Moorland
- Heather & grass community of great wildlife value. Regular burning maintains plagioclimax.
- Threats
- reservoir construction
- increased visitor pressure
- Coasts & Estuaries
- Threats
- port developments
- pollution from rivers
- pollution from industrial developments such as oil
- Threats
- Lowland Heathland
