| Black-breasted Buttonquail |
Endangered rainforest
in the Sunshine Coast hinterland - the habitat of what may be the
largest surviving population of the rare Black-breasted Buttonquail –
continues to be bulldozed during logging operations. During recent
visits I was concerned to see that an area of vine scrub frequented
by nesting buttonquail in Imbil State Forest had been felled.
Subtropical lowland rainforest is listed federally as critically
endangered.

The company conducting
the harvesting, timber giant HQPlantations, says it has modified
management practices to help protect the buttonquail and other
threatened species. Vine scrub remnants in the state forest have been
a reliable site for the scarce and cryptic buttonquail for at least
the past 30 years. The Black-breasted Buttonquail is the only bird
species endemic to south-east Queensland. Buttonquail sites in the
Imbil area are frequented by other scarce and difficult-to-find birds
such as Barking Owl and Black-chinned Honeyeater.

Remnant areas of
lowland rainforest survive among hoop pine plantations in Imbil State
Forest. These remnants are protected under Queensland's Nature
Conservation Act and Vegetation Management Act; they can not be
cleared to expand the plantation estate. However, “native forest
buffer areas” remain under the management of HQPlantations.
It was evident that
vine scrub has been bulldozed during current logging operations, with
rainforest trees obvious among large piles of vegetation debris. A
newly cleared 200m strip of scrub, along with the edge of a mature
pine plantation which was logged at the same time, was an important
feeding and nesting area for Black-breasted Buttonquail.

I submitted a
plan for the rewilding of the 21,000ha Imbil State Forest in
2019. That proposed a halt to logging hoop pine plantations,
facilitating the regrowth of the subtropical rainforest that occurred
naturally over the area before it was cleared. I suggested that as a
trial, 200ha of state forest plantation adjoining Conondale National
Park be left unlogged as rainforest regrowth is monitored. Although
this constitutes a tiny fraction of the 330,000ha of state forest in
Queensland under the control of HQPlantations, the company rejected
the proposal.

I reported
in June last year that well-meaning land-care volunteers were
removing lantana from Black-breasted Buttonquail habitat in the area.
Lantana is an exotic weed that generally should be removed, but in
the case of this species and some other wildlife, it provides a
valuable service. The natural habitat of the buttonquail is the
lowland rainforest of south-east Queensland, almost all of which has
been cleared. Sites where birds survive, like those in Imbil State
Forest, are often flanked or invaded by lantana thickets. Buttonquail
feed and seek shelter in them; lantana provides a degree of
protection from feral cat and fox predation.

In response to that
blog post, the volunteers agreed to stop removing lantana. They have
planted a large number of trees in an area where weeds had been
removed. I found that behind this newly planted stand of young trees,
a 200m track has been bulldozed by HQPlantations through another
important buttonquail feeding area. I also saw an assortment of empty
cans and bottles, broken machinery and other rubbish.

I failed to see
buttonquail during several visits over the past couple of weeks,
which is unusual, although some platelets were present. The
population appears to be steadily declining. A constant procession of
trucks carrying logs and heavy equipment traversed the road
dissecting the buttonquail site during my visits.
However, the good news
is that HQPlantations responded positively when I approached the
company recently, with senior company officers agreeing to meet me
on-site. They explained that the recently bulldozed track was
intended as a fire break for forthcoming control burns. The company
had been unaware of the presence of Black-breasted Buttonquail and
other rare wildlife. I was assured that fire control operations would
be conducted in a way that took account of the need to protect the
birds' habitat. That was reassuring.
Regarding the recent
removal of buttonquail breeding habitat adjoining the newly logged
pine plantations, there were no clear answers. However, the
suggestion was that vine scrub was removed to facilitate access to
pine trees being logged, which the company is legally entitled to do.
The company said in a
statement: “We use aerial photography, LiDAR (provides high
definition ground surface and canopy mapping), original plantation
history records and field inspections to ensure our harvesting
remains within the original plantation boundary inclusive of old
boundary tracks. Our management of areas of remnant native vegetation
adjacent to plantations is focused on maintaining biodiversity values
and protecting the adjacent plantation resource. This is primarily
undertaken via pest and fire management programs. We do not harvest
timber products (excepting introduced pine wildlings) from these
areas.”

Expanding more broadly,
the company said: “In some instances, we develop and implement
additional species specific management procedures where forest
activities may pose a significant threat, - for example koala
protection during harvesting operations. We collaborate with local
groups to improve the protection and management of endangered and
vulnerable species. For instance, we are working with the Burnett and
Mary Regional group researching Mary River Cod and other threatened
aquatic species within Tinana Creek. We are working with groups
including the Macadamia Conservation Trust, regarding the Southern
Macadamia Species Recovery Plan.”

HQPlantations also
noted: “As agreed under our Plantation Licence, we have several
plantations and associated native forest areas which are being
progressively handed back to the State Government, following harvest
of the current plantation crop, to be transitioned into permanent
conservation estate. As at June 2025, there were three such areas
still within the Licence Area totalling approximately 1,200 ha
(approximately 700 ha plantation).” These are steps in the
right direction, but we remain a long way from a satisfactory reserve
plan for protect what remains of critically endangered lowland
rainforest.
