project in the spotlight
8,000 seedlings and growing strong
With seven native species, 200 planting hours and
8,000 seedlings; this year’s Alcoa Anglesea mine
rehabilitation planting really was an incredible effort.
This planting session forms part of Alcoa Anglesea’s
regular cycle of mine regeneration activities. The cycle
is conducted over a one year period and aims to
minimise the impact of the site’s mining activities by
restoring the land to its original composition including
the correct species of vegetation.
Photo: Deb Delgrosso and Marty Henzi.
Anglesea power station Environmental Scientist Lisa
Mills said the species planted include tea-tree,
eucalyptus, casuarina, banksia and grass trees.
“We have a target to rehabilitate a larger area of land
than what we clear each year,” said Lisa. “We also aim
to re-establish greater than 100 per cent of species
richness based on the botanical surveys we conduct in
the Anglesea heath each year.”
“We provided the seeds to Mike Robinson-Koss from
Otway Greening to propagate on his property,” she
said. “He delivers the seedlings to us when they are
large enough to be transplanted.”
Lisa explained that mine rehabilitation species
richness is when the average number of indigenous
plant species in 18 month old rehabilitation is at 100
per cent of the number found in representative unmined heath sites.
“Planting the seedlings is a very labor intensive
process. Our two external contractors, Deb Delgrosso
and Marty Henzi, spent three weeks planting each
seedling by hand. Certain species also needed to be
protected using stakes and plastic tree guards to help
improve their chances of survival.”
This year, in addition to the regular tree planting
program, the power station established its first ever
Banksia Marginata seed production area.
The size of the land re-vegetated each year depends
on how much land needs to be cleared for the
following year’s mining. When an area is mined, each
layer of soil removed is carefully re-laid in the same
order at the new regeneration site. Contours are
created to stop erosion from runoff and mulch, made of
plants cleared from the new mine area, is spread over
the site before the seedlings can be planted.
“The Banksia Marginata is an intrinsic part of the flora
of the Anglesea heath,” said Lisa. “Remnant
populations are fragmented, making seed collection a
physically difficult, time consuming and expensive
process. The development of a seed production area
will assist in the future management and inclusion of
this important species in restoration and revegetation
activities within Alcoa’s mining area.”
