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.” keeping you informed Alcoa Anglesea has a range of activities and publications available to people who would like to learn more about Alcoa.
