Transcript of Ecosystems along routeways

Wildlife corridors
A wildlife corridor links two similar wildlife habitats e.g hedgerow and footpaths
Railway lines and motorway verges become wildlife corridors in urban areas as wildlife quickly adapts to the conditions.
The corridors can be non-continuous (clumps of habitats not too far apart)
Many areas deliberately create wildlife corridors e.g Milton Keynes and Newcastle upon Tyne
Ecosystems along routeways
Routeways - motorways
The soil that is removed from the routeway to build the motorway is piled up on the sides of the road.
When they are built the verges are prepared to make a good soil bed.
Grass seed mix and flower meadow seed are planted to give a variety of vegetation.
Trees and shrubs can also be planted e.g sycamore and silver birch.
Other plant species begin to develop and urban niches are developed.
Railways
Along the railways Oxford Ragwort grows.
O.R is part of the
Senecio
genus which is a yellow flowered plant, native to rocky mountainous areas.
In the 1700 it was brought over by the Duchess of Beaufort and was transferred to the Oxford Botanic Garden.
O.R became connected to the railways so began to spread across the UK with the railway system.
Urban Blight
Argicultural land near a city begins to deteriorate and are less farmed due to different factors such as:
vandalism e.g fly tipping
pressure of tourism and leisure taking up farmland
pressure of tourism and leisure e.g dog walkers, off road cyclists etc
pollution from traffic, housing, litter etc
farmers care less about the land and neglect it
developers use the farmland
All these factor affect the ecology of the area.
Garden creation
There is a range of different gardens in the rural/urban fringe:
Paved areas and patios
- ecosystems are deliberately destroyed increasing the potential of flooding.
Well kept lawns which become monocultures
- chemicals limit the development of plants and animals (even worms)
Gardens with exotic, imported plants
- compete with indigenous species and discourage wildlife species
Wildlife gardens
- encourage growth of all species creation a high biodiversity
Ecosystems along routeways
Routeways through and between urban areas create new, different ecosystems due to varying factors such as:
construction altering the surface
different drainage systems
traffic spreads different seeds
along busy routeways there is little to none human interaction with the ecosystem
pollution due to traffic fumes and litter
additional salt is added to the ecosystem in the winter
