  • 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.
