BROKEN HEAD QUARRY, BROKEN HEAD NSW
Broken HeadQuarry is a well-established sand and gravel quarry located within an area of high conservation vegetation which provides habitat for a number of threatened species. Blackwood Ecology were engaged in 2006 to overhaul the existing environmental management program and implement a program of works that would address the quarry's environmental obligations and guide the restoration of site habitats well into the future.
These works include extensive revegetation, regeneration and weed control, a seed collection program with onsite nursery, installation of fauna nest boxes for bats and arboreal mammals as well as cane toad exclusion fencing around sedimentation ponds. Blackwood Ecology works closely with the quarry manager to develop innovative environmental management measures. Monitoring of these measures is undertaken on a biannual basis to assess the effectiveness of works and report to Council and NSW Government agencies.
REF, GROUND PENETRATING RADAR SURVEY FOR BURIED SEAWALL, LENNOX HEAD, NSW
The Ballina Shire Coastline Management Study produced in 2007 identified the existence of an old buried rock seawall along Seven Mile Beach at Lennox Head, NSW. Ballina Shire Council commissioned a Ground Penetrating Radar study to locate the seawall and engaged Blackwood Ecology to complete an Ecological Assessment and Review of Environmental Factors (REF) to identify potential impacts associated with the establishment of transects through dune vegetation to allow for radar equipment to be utilised. The Ecological Assessment identified suitable locations for transects, avoiding areas of Littoral rainforest and minimising impacts on foredune vegetation.
MALLANGANEE QUARRY SITE REHABILITATION MANAGEMENT PLAN
Mallanganee Quarry is an active road base gravel quarry located on the boundary of Mallanganee National Park in the Kyogle Council LGA. Blackwood Ecology were engaged to prepare a Site Rehabilitation Management Plan (SRMP) to guide site rehabilitation in a progressive manner in accordance with extraction sequences, and develop a final vision for the site following cessation of quarrying activities in a projected timeframe of 20 years. Rehabilitation efforts were divided into a number of stages to be completed over the lifespan of the quarry. The SRMP detailed a number of management measures including topsoil management, weed management, landform management, revegetation methods and a list of suitable species representative of the surrounding indigenous vegetation. The Plan also included rehabilitation of a section of Mallanganee National Park and was approved by the NSW Office of Environment and Heritage.
CURRUMBIN RIDGE DEVELOPMENT, CURRUMBIN, QUEENSLAND
Currumbin Ridge is a residential development located amongst Blackbutt forest and rainforest overlooking Currumbin Beach on the southern Gold Coast. Blackwood Ecology provide regular consulting services to the site developers and oversee the implementation of the Vegetation Management Plan and the Tree Protection Plan. These documents provide the framework for revegetation and restoration works on the site, protection of trees and site vegetation during the ongoing construction and installation and monitoring of fauna nestboxes.
POTTSVILLE COMMUNITY HEALTH CENTRE TREE PROTECTION AND HABITAT RESTORATION PLAN
As part of development consent conditions for the Pottsville Community Health Centre the Northern Rivers Area Health Service required the preparation of a Tree Protection and Habitat Restoration Plan (TPHRP) to minimise potential indirect impacts to retained areas of vegetation and provide additional Koala feed trees on the site. Tree Protection Zones (TPZs) were calculated and established for all retained trees in close proximity to the development envelope. Blackwood Ecology worked closely with local council officers and Woolam Constructions to ensure these TPZs were incorporated into environmental management practices. Where there was insufficient space due to design requirements, a number of specific protection measures were incorporated into the plan including root barrier systems, structural soils and permeable pavements.
