Bush Regener<strong>at</strong>ion:<br />
The str<strong>at</strong>egic approach to rebuilding<br />
remnant rainforest<br />
CONTRACTING SERVICES by Jolyon Froude<br />
Last month the Contracting team completed work on two local<br />
properties as part of a Rainforest Recovery Project facilit<strong>at</strong>ed by<br />
<strong>Barung</strong> with the aim of protecting and enhancing several key<br />
rainforest remnants in the Maleny area.<br />
The first property we worked on belongs to Maureen and Mitch<br />
O’Brien. This amazing 100 acre property ranges over a series of<br />
seven n<strong>at</strong>ural terraces cascading down the side of the Range in<br />
the upper Stanley River c<strong>at</strong>chment. Maureen and Mitch are<br />
extremely dedic<strong>at</strong>ed land owners, working tirelessly over the ten<br />
years they have owned the property to control large-leaf privet,<br />
lantana and a range of other weeds. They must have poisoned<br />
tens of thousands of privets, earning Maureen the nick-name of<br />
‘the Privet Lady’.<br />
The property has abundant remnant rainforest confined mostly to<br />
the gullies and steep slopes between the fl<strong>at</strong>ter n<strong>at</strong>ural terraces,<br />
and the decade of weed control has seen massive amounts of n<strong>at</strong>ive<br />
plant regener<strong>at</strong>ion spreading out from these areas. As well as<br />
poisoning privet, other techniques used to achieve this outcome<br />
have included progressive spraying of lantana and herbaceous<br />
weeds and str<strong>at</strong>egic c<strong>at</strong>tle grazing. The property is home to several<br />
rare and thre<strong>at</strong>ened species and is one of the most impressive<br />
large-scale rainforest regener<strong>at</strong>ion projects I have seen.<br />
The second site we have worked on is the Book Farm in the<br />
headw<strong>at</strong>ers of the Obi Obi Creek <strong>at</strong> Reesville. This is owned by<br />
Richard Dent and Jill Morris who are strongly committed to the<br />
preserv<strong>at</strong>ion and enhancement of the key rainforest remnant on<br />
the property. This is probably the best veget<strong>at</strong>ion remnant on the<br />
upper Obi, consisting of six acres of undisturbed subtropical<br />
rainforest along the creek, surrounded by regener<strong>at</strong>ing forest and<br />
plenty of privet, lantana and other weeds. The value of this small<br />
remnant is clear when viewing the surrounding area, which has<br />
been almost completely cleared for dairy farming.<br />
On both properties our contracting work was focused on the Bush<br />
Regener<strong>at</strong>ion approach: the str<strong>at</strong>egic control of weeds to facilit<strong>at</strong>e<br />
the n<strong>at</strong>ural regener<strong>at</strong>ion processes of the forest systems.<br />
This sounds simple enough … The key is being str<strong>at</strong>egic and<br />
efficient in undertaking the work. There are always more weeds<br />
than resources to remove them, so it is important to focus on areas<br />
and techniques th<strong>at</strong> will maximize the positive outcomes. Working<br />
out from more intact areas into more disturbed areas is one of the<br />
main str<strong>at</strong>egies. It is also important not to clear too much <strong>at</strong> once<br />
thereby increasing light levels too dram<strong>at</strong>ically and cre<strong>at</strong>ing perfect<br />
conditions for other weeds. (Continued next column.)<br />

Plant identific<strong>at</strong>ion skills are vital ; being able to pick out a dozen<br />
or two weed species from well over 100 n<strong>at</strong>ives <strong>at</strong> a glance is the<br />
essence of the process!<br />
When we think about enhancing and extending remnant veget<strong>at</strong>ion<br />
we often (sometimes too often) focus on planting trees. However<br />
<strong>at</strong> the right site the bush regener<strong>at</strong>ion approach offers a range of<br />
advantages over tree planting. It is usually much more efficient in<br />
terms of time and money to remove the weeds and facilit<strong>at</strong>e n<strong>at</strong>ural<br />
regener<strong>at</strong>ion than it is to plant and establish tube stock. The<br />
regener<strong>at</strong>ion approach also ensures th<strong>at</strong> the right species are used<br />
(n<strong>at</strong>ure doesn’t make mistakes!) and th<strong>at</strong> inappropri<strong>at</strong>e genetic<br />
m<strong>at</strong>erial from elsewhere is not being introduced to the site through<br />
planted stock.<br />
Remnant rainforest p<strong>at</strong>ches are of immeasurable value. They<br />
provide immense insight into wh<strong>at</strong> the landscape was like before<br />
it was cleared – the n<strong>at</strong>ure of the plant communities and how they<br />
were distributed. Bush regener<strong>at</strong>ion is usually the best way to<br />
protect and enhance the integrity and long-term sustainability of<br />
remnant p<strong>at</strong>ches. If you are a local landowner interested in<br />
protecting and enhancing remnant veget<strong>at</strong>ion, <strong>Barung</strong> Contracting<br />
can give you advice and practical assistance with all aspects of<br />
the process.<br />
