Prescribed burning—Walpole
1052. Hon Jess Beckerling to the Minister for the Environment:
I refer to the
current prescribed burn in Willmot–Quindinillup FRK 112 in the Walpole
Wilderness Area.
(1) How many hectares is the Department of
Biodiversity, Conservation and Attractions aiming to burn?
(2) What is the total number of individual aerial
incendiaries that will be dropped?
(3) Is the area known habitat for Carnaby's and
Baudin's black cockatoos?
(4) Given that both Carnaby's and Baudin's are
endangered and this is their nesting season, with juveniles still in the nest
and not mature enough to fly away, how many nesting hollows were checked prior
to this burn?
(5) What is DBCA's success criteria for this burn?
(6) What cockatoo protection and survival measures
are included in DBCA's success criteria?

I thank the
honourable member for some notice of the question and provide the following
answer on behalf of the Minister for the Environment. It is a detailed question,
so the answer is detailed.
(1) The burn area covers approximately 15,108
hectares, with a target to burn at least 60% of it through prescribed fire.
(2) The number of capsules used varies based on
the timing and spacing of aerial ignition required to achieve the desired fire
behaviour.
(3) The area is identified as potential habitat
for both species of black cockatoos.
(4) Department of Biodiversity, Conservation and
Attractions staff undertook surveys for nesting behaviour prior to burn
implementation, with no nesting sites identified.
(5) The five success criteria are: Drakaea micrantha to be excluded if not burnt
between 15 October and 30 April; high burn severity in mature forest with
canopy height greater than 15 metres not to exceed 40%; very high burn severity
in mature forest with canopy height greater than 15 metres not to exceed 10%; a
mosaic of burnt and unburnt vegetation throughout the burn area for fauna
refuge and movement; a minimum of 60% of the burn area is burnt by prescribed
fire.
(6) Staging the burn
over several months created spatial and temporal variation, helping manage
impacts and achieve a mosaic of burnt and unburnt areas for fauna refuge
and movement.
