What is a wildlife corridor?
‘A wildlife corridor is a link of wildlife habitat, generally native vegetation, which joins two or more larger areas of similar wildlife habitat. Corridors are critical for the maintenance of ecological processes including allowing for the movement of animals and the continuation of viable populations.
By providing landscape connections between larger areas of habitat, corridors enable migration, colonisation and interbreeding of plants and animals’. (Dept of Environmental Affairs, N.S.W.)
Create a wildlife corridor in your garden.
You may have heard or read about the alarming decline of insect populations world-wide. Loss of habitat due to alien invasive encroachment, property development, farming, use of herbicides and insecticide, climate change have all been blamed for this very alarming occurrence. The cumulative efforts of gardeners, landscapers and commercial farmers across the country planting wildlife-friendly gardens and preserving natural pockets in the landscape can begin to reverse the habitat destruction and species loss that has occurred over the last century.
When gardeners add indigenous plants to their landscapes they create stepping stones connecting formerly isolated habitat islands. Biologists call these “wildlife corridors,” and they’re critical for species to find the food, shelter, and breeding opportunities they need to thrive. Every garden, no matter how small, becomes part of the solution.
You don’t have to tear up your whole garden; make small changes, one plant at a time. For the biggest impact, especially in small suburban yards, select plants that support the greatest number of species. Trees and shrubs sustain more species than perennials and are the best place to start.
Indigenous plants are critical to the survival of our most cherished animal species. That’s because all ecosystems begin with plants, which harness the sun’s energy through photosynthesis. Animals consume the plants and transform the energy into tissue that’s consumed by other animals, and so it goes up the food chain. Without plants, ecosystems collapse. But not just any plant will do. Many insect species will only eat plants with which they co-evolved. That’s why indigenous plants play such a critical role in healthy habitats.
