Although the threats mentioned in the reading are serious, effective measures can be taken to save koalas. First, planting trees seems like an obvious solution to the problem of habitat loss. But remember that fragmentation, or cutting habitats into parts, makes the problem of habitat loss even worse. So planning has to be done strategically. Scientists have suggested creating vegetation corridors to reconnect habitats that are fragmented or separated by treeless land. A vegetation corridor is a long, narrow strip of trees that connects different patches of forest by creating a pathway of trees in between. Koalas can follow these strips of trees from one forest patch to another. Second, collisions with cars can be reduced thanks to wildlife crossings. Wildlife crossings are structures that allow animals to cross roads safely. The Australian government has found a cost-effective way to provide wildlife crossings. They use structures that already exist, specifically tunnels that carry water under roads. These tunnels were originally built to allow water from rivers or streams to pass underneath roads. Since there's usually extra room in the tunnels above the water, elevated platforms or walkways are being built inside the tunnels. On these new platforms, koalas can move safely through the tunnels under the roads without even getting wet. Koalas have already started using the tunnels, and automobile collisions are decreasing. Finally, a solution to the fencing problem lies in encouraging homeowners to provide koalas with some means of quick escape from backyards. Koalas have a hard time climbing fences with flat surfaces, but a tree or a round pole is easy for koalas to climb. So people could plant trees near fences, and koalas could use the trees as a natural ladder. Another solution is to use a tall wooden pole and lean it against the fence at an angle. Koalas can usually escape from dogs quickly enough by climbing up round poles or trees.
