Animals have to move - within the Scenic Rim and beyond
INSURANCE AGAINST TOTAL LOSSIf animals are eliminated from a particular area, if some of their relatives have been able to move elsewhere
they may still survive and their offspring return, or at least persist in another place.
GENETIC DIVERSITYIf animals populations are confined to small areas, they can become inbred, losing genetic diversity and becoming
less fit from one generation to the next. If they can move around more they can mate with Ďoutsidersí and
maintain genetic diversity, which may help the population survive long-term.
BETWEEN HABITATSSome animals move between habitat types Ė for instance the Lewinís honeyeater forages deep within the rainforest for fruits, but comes into eucalypt forests in search of nectar-rich flowers.
Conserving just one kind of habitat wont be enough for these species.
ALTITUDINAL within the regionGrey fantails, golden whistlers, and others use dense mountain forests for breeding in spring and summer but forage in more open areas at lower altitudes during winter.
Even the bowerbirds will come a little way out of the rainforests during winter, but the wompoo fruitdoves and catbirds, although moving lower down the slopes, generally donít like to leave the cover of the rainforest.
Coxenís figparrot, now almost extinct, no longer has enough lowland rainforest to support itself during winter.
LONG DISTANCESome fly long distances - usually north-south Ė every year.
Some have to fly long distances to find something \ fruiting or flowering - e.g. flying foxes have flown 200km or more in one night, then return the following night after not finding it
Waterbirds may have to fly many kilometres in a drought to find water.
AT MATURITYTo seek a new territory
EVERY YEARBetween over-wintering and breeding areas
AS NEEDEDNomadically, to seek new food or water sources.
Some donít like to fly out of the forest, but may go short distances between habitat patches.
Some canít fly but will cross cleared land between forests.
What problems can they face?Too far between habitat patches.
Nowhere to go.
Not enough food along the way.
Dogs, cats, foxes etc.
Native predators: escape from native predators can become harder if there is less shelter.
Natural or human-induced damage to corridors.
How can we help them?Habitat conservation and restoration.
Corridors that a variety of animals can use.
Corridors wide enough to avoid edge efects and buffer against disasters.
Control dogs and cats, especially at night. They need plenty of exercise, but not by themselves at night.
Shelters for gliding gliders. Poles can be provided across open areas, and gliders can glide from one to the other to reach the forest, but owls soon find it easy to predict their movements and catch them.
Shelters are needed to protect them while using the poles.
Careful driving, especially at dusk and dawn.
With care and intelligent planning, maybe we CAN still enjoy our wildlife for decades or even centuries to come!
