Wildlife Corridors

Wildlife corridors (biodiversity corridors) are corridors of land planted with appropriate vegetation, which allow flora and fauna to traverse a wider territory. This allows specifically  the wildlife to:

  • Repond to environmental variability, eg. move from food/water scarce areas to food/water plentiful areas.
  • Respond to population pressure - move from over-populated to under-populated areas.
  • Access a wider range of breeding partners, thus preventing inbreeding and loss of genetic diversity in a local population.

In urban areas of Australia, clearing of native vegetation has created a sea of developled land dotted with the occasional island of preserved bushland. To promote wildlife movement, these fragments need to be reconnected, by establishing (replanting) vegetated corridors with locally-indigenous species on previously cleared land.

Corridors provides shelter, food and protection from predators by imitating the structure and diversity of native vegetation. Birds, reptiles, amphibians, mammals and insects that would otherwise be isolated in one native forest patch, can utilise corridors to move between patches with relative ease and safety. Ridgelines and creeklines are good candidates for wildlife corridors, because substantial vegetation there prevents erosion by wind and flowing water. Planting or retaining vegetation alongside roadways has the additional benefit of providing flexible impact barriers that screen out our lives from theirs.
