The 400 year old Moreton Bay Fig is now just a stump after it snapped and blew over on Thursday, leaving a 50 metre gap across the forest canopy. But it's all part of the natural process with these trees, which are structurally much poorer than they appear.

Kevin Carter of the National Parks and Wildlife Service said Moreton Bay Figs are part of the 'Strangler Fig' family that grows from the canopy of another tree down to the ground.

"Its roots form around the trunk of the existing tree and slowly make their way to the ground, which means that once the original tree rots and dies, the Moreton Bay Fig is hollow in the middle," he said.

Kevin inspected the site on Friday and said it was now cleared and safe for public use.

"The debris should rot away in a short time and it will now make room for others to grow and establish themselves as the dominant tree," he said.

"The leftover branches and leaves make rich and fertile mulch so other trees will come through and thrive."

National Parks were also pleased to find that there was no structural damage to the board walk following the incident. Over the coming months the rainforest regeneration team and parks staff will be working together to ensure that weeds do not regenerate on the ground underneath the gap in the canopy.

"We'll be keeping a close eye on that spot from now on," Mr Carter said.

They will also be monitoring the bat population and roosting areas as the tree stood in the middle of the maternity area for bats.

Although the area has been cleared, National Parks and Wildlife are urging people to stay on the board walks should they wish to have a look at the fallen tree.
