"Not only do we collect seeds from this particular tree here in Canberra but we also collect from this Candlebark in other areas of Australia because they are growing under different conditions and they might perform differently under different environments."

Tim is the team leader at CSIRO's Australian Tree Seed Centre, where the collected seeds are stored at various temperatures - from room temperature, refrigerator through to freezer cold, down to an extreme minus 80 degrees Celsius.

There are 30 thousand samples of seeds from about thirteen hundred different species, including some that could have got there by themselves.

"These ones have, for example, wings so that the wind can pick up the wing, carrying it a reasonable sort of distance. This one here is one of the wattles, which is attractive to birds so it has a coloured part on the seed, which they can eat and they pass the seed out later on and these ones here have a sort of flotation device on them which means they can be floated carried on water and floated away.

But the seeds also need a helping hand to reach their final destination.

In a world that needs all the new trees it can grow, The Australian Tree Seed Centre provides the seeds, and information about how the trees will best grow and what uses they can serve, not only in Australia but all around the world.
