Survey Site 3

Fully restored indigenous vegetation along creekline.

History:

In the past, this property has been subjected to low-intensity logging. The creek has been altered via earthworks to the banks and the construction of a small dam. Many Habitat-changing environmental weeds invaded the site at some point, and had spread throughout the bushland and creekline, where they smothered indigenous species.

A variety of woody weeds infest this bushland.

Action:

EVC 29: Damp Forest. Victorian Status: Endangered
EVC 18: Riparian Forest. Victorian Status: Vulnerable

Over the years, the owner saw the weeds spread at an alarming rate, choking the bushland. He knew that before long, all the bushland would be destroyed, and decided to take action. Extensive weed control works were commissioned, using environmentally sensitive techniques to protect the creek and its abundant tree ferns. The native vegetation began to regenerate of its own accord, so no revegetation was required apart from the addition of some blackwoods to protect the ferns from strong sunlight.                            

These woody weeds have been poisoned to enable regeneration of the understory.

It has taken a number of years of intensive weed control to eliminate all the established weeds, and to wear down the huge seed bank in the soil.                                

The diverse understory has regenerated, following weed eradication.

It was decided that the small dam should remain in place, as earthworks would probably cause more damage, in particular to the tree ferns that have grown up on its banks.

Future Aims:

Weed control will continue, as the more damaged areas are still regenerating. Weeds from surrounding properties are attempting to take advantage of these incomplete patches.                            

Status:

The natural vegetation has reclaimed the site, and has once again become valuable habitat. As a result, fauna that had abandoned the site has returned. Furthermore, the abundance of existing species has increased.                            

This graph shows that the diversity of wildlife species making use of the bushland increased following weed control works.

This graph shows how the indigenous species were able to regenerate once the competition from weeds was removed.
