- Ecologies along Routeways
- Why are Routeways Destinctive Habitats?
- Exotic Species are brought in by traffic
- They act as 'wildlife corridors', similar to rural hedgerows
- Railway Lines
- Enable animals to move around cities.
- During the days of steam, frequent fires burnt out tall species and allowed light through
- Allowed light demanding species such as Foxglove and Primrose to Establish.
- Windblown seeds are sucked along by trains, allowing plants such as the Oxford Ragwort to establish
- As the track is fenced off, there is a lack of human interference
- Encourages wildlife such a badgers and urban foxes.
- Bramble-filled area provide nesting sites for birds.
- Roads
- Homes on verges and embankments for kestrels and scavenging birds
- Nitrogen-rich exhaust fumes encourage the growth of some wild flowers.
- This in turn, increases the presence of insects and animal further up the food chain.
- Number of wildflowers sometimes reduced by mowing.
- Some roadsides managed - trees shrubs and flowers are planted which increases biodiversity.
- In London, the London Plane Tree is Planted as well-adapted to urban environments.
- Canals
- Act like long ponds, providing a habitat for a variety of aquatic plants such as the yellow flag iris.
- Attracts waterfowl (moorhens, ducks, kingfishers)
- Attracts water-loving insects such as dragonflies and damselflies.
