example and date pf a recent extreme weather event in the UK
- February- March 2018
- beast from the east
causes of the beast from the east
- a change to northern polar jet stream drew in cold air to the UK from the east
- brought a severe chill from thousands of miles away
- air picked up moisture over the north sea bringing snow to the east coast
- 1st March depression called storm Emma moved in from the Atlantic –> even more snow

example of a small scale UK ecosystem
- Epping forest
- ancient deciduous woodland
- managed to some degree for 1000 years e,g hunting and timber
- a wide variety of natural tree species that include beech, elm, oak and ash
- a shrub layer consisting of hazel and holly, along with grasses, brambles, fern, bracken and flowering plants
- 177 species of lichen and moss, many primary consumers including insects and small mammals and deer along with 38 species of birds
- 700 species of fungi, important decomposers, which are common due to a large amount of dead wood
- over 100 lakes and ponds provide important habitats for numerous fauna species and flora
example of a river valley in the UK
- river Tees
- found in NE England
- 137 km long
- source at Cross fell in the Pennines hills
- mouth north sea
- upper course- V-shaped valleys, interlocking spurs, high force waterfall tallest in England (21m), horizontal cap of of whinstone ( hard) over carboniferous (soft)
- middle course- meanders, floodplain at Barnard castle
- lower course - town of Yarm found inside meander, Ox bows, levees, Tees estuary, Mudflats at Tees mouth ( Middleborough) petrochemical and nuclear plant at mouth
example of a flood management scheme in the UK
- Jubilee river relief channel
- found on the river Thames
- aims to reduce flooding in Windsor and Eton
- founded by environment agency costing £330 million
- opened in 2002
- 11.17km long
- UKs largest artificial channel
- 5 damns along its course
social issues for the Jubilee river relief channel
- protects wealthy Maidenhead and Eton but at the expense of less affluent Wraysbury
economic issues of the Jubilee river relief channel
- one of the UKs most expensive schemes but at £330 million only 1 of 4 channels was built due to the EA running out of money
- damns damaged in 2003 floods and expensive to maintain
- scheme has transferred the problem downstream which led to severe flooding in 2014
environmental issues of the Jubilee river relief channel
- concrete damns are unattractive and spoil the natural environment, habitats below confluence damaged in 2014 floods
- algae collects behind damns damaging aquatic habitats
an example of an upland area in the UK affected by glaciation
- lake district
- located in the Cumbrian mountains (NW England) west of the M6
erosional landforms in the lake district
- striding edge - arete
- Red tarn/Easedale Tarn - corrie
- Windermere/ Coniston - Ribbon lakes
- langdale - U shaped valley and hanging valley
depositional landforms in the lake district
- erratic’s - bowder stone, Borrowdale
- swarms of drumlins - Swindale
- terminal moraines - Borrowdale
- Moraines - Easedale valley
what is the mountain called in the lake district
scarfell pike England’s highest mountain at 978m
what is tourism like in the lake district
- 41,000 residents
- 19.9 million tourists a year
- tourists spend £1.9 billion a year
- lake district national park authority works with 25 partner organisations aiming to secure long term sustainability
opportunity’s in the lake district
- glacial features create opportunity e.g ribbon lakes for water sports e.g Windermere adventurous activities
- quarrying - honister slate mine- blue grey lake district slate
- Ambleside - honeypot site at northern end of lake Windermere (17km long)
- national trust ( wray castle), national park
challenges in the lake district
- second home ownership has forced up house prices - 15% are holiday homes
- jobs are seasonal and poorly paid
- footpath erosion damages landscape
- pollution from cars damages environment- congestion on narrow country roads - 90% come by car
- conservationists aiming to protect the landscapes & tourists have conflicting interests - walkers v mountain bikers, walkers v farmers, conservationists v tourists
strategies to manage impact in the lake district
- creation of honeypot sites - active zoning- focuses tourists on areas such as Windermere & Ambleside to protect other areas
- reducing congestion- B4 bus network, £7million spent of ‘drive less, see more’ initiative
- footpath erosion - fix the fells repair paths with local stone, improve signage, plant native plants that are able to withstand trampling
- pressure on property - give planning permission for new homes and restrict them to locals only
