PROJECTS
Ecology and Environmental Projects Across NSW
Biodiversity, approvals, and construction-stage ecology for development, infrastructure, government, and education projects across New South Wales.
Recent work across Sydney and regional NSW
Since March 2024, ESEA has delivered biodiversity development assessment reports (BDARs), flora and fauna assessments, reviews of environmental factors (REFs), vegetation management plans (VMPs), targeted surveys, fauna rescue, and clearing and habitat certification across Greater Sydney and regional NSW.
The projects below are a selection, chosen to show the range of sites, constraints, and clients we work with. Each one lists the location, the year, and the services ESEA provided, and links to a fuller write-up.
200 Lot Subdivision Ecology, Advance Street Schofields
Biodiversity assessments, a Vegetation Management Plan and nest box compensation works for an approximately 200 lot subdivision, successfully defended in the Land and Environment Court without a reduction in yield.
Sand Quarry Biodiversity Constraints, Old Northern Road Maroota
Environmental support for a State Significant extractive industries proposal at Maroota, planned around large areas of retained vegetation and threatened species habitat.
Grose River Bridge Sea-Eagle and Koala Management
Environmental documentation and on-site ecology for a Transport for NSW bridge project in the Hawkesbury, with koala and White-bellied Sea-Eagle management running alongside construction.
Pre-Demolition Thermal Survey, Sydney Inner West
Thermal imaging, endoscope inspection and visual assessment of every building cavity before demolition, which confirmed no fauna were present and let demolition proceed on schedule.
Biodiversity Stewardship Due Diligence, Mount Wilson
A Biodiversity Stewardship Agreement due diligence letter for a property at Mount Wilson in the Blue Mountains, assessing whether the land suited a stewardship pathway before the landholder committed to…
Arboricultural Impact Assessment, Norwest
Arboricultural impact assessments for subdivision proposals on Windsor Road at Norwest, prepared alongside a Small Area BDAR that identified hollow-bearing stags and a large Forest Red Gum with multiple hollows.
Rezoning BDAR and Riparian Assessment, Kemsley Park Grose Vale
Biodiversity and riparian assessment for a residential rezoning on land containing critically endangered Cumberland Plain Woodland, with multiple riparian corridors declassified through the water agency.
Richards Precinct Ecology, Riverstone West
Ecological assessment, management planning and construction-phase support across an approximately 400 hectare development site in Blacktown, carried as one continuing project ecologist commission.
Riparian Vegetation Management Plan, Mudgee
A riparian Vegetation Management Plan for a residential subdivision at Mudgee, with two management zones designed around a proposed low-flow channel and high-flow easement.
Clearing Certification and Squirrel Glider Relocation, Marsden Park
During supervised clearing at Marsden Park, five Squirrel Gliders found in a hollow received veterinary assessment before relocation, and the clearing certification letter recorded the event.
Water Infrastructure REF, Austral
A Review of Environmental Factors for about 428 metres of external potable water infrastructure serving a 31 lot subdivision at Austral, with safeguards tailored to the adjacent riparian corridor and…
Industrial Development Ecology, Lee Holm Road St Marys
Ecological input to a large-scale industrial development that used the site's contaminated-land and flooding constraints to focus development within more disturbed areas.
Powerful Owl Acoustic Survey, Castle Hill
Ultrasonic and acoustic monitoring combined with endoscope inspection to identify Powerful Owl habitat at Castle Hill, so proposed new floodlighting could be designed around it.
Controlled Activity Exemption, Smeaton Grange
Controlled activity exemption advice for an industrial development at Smeaton Grange that secured departmental concurrence that a separate approval was not required for the works as designed.
Reserve Pre-Clearing and Drone Survey, Campbelltown
A pre-clearing report covering 78 trees at a Campbelltown reserve, followed by a drone inspection that found nesting native birds and placed the works on an ecological hold until they…
COUNCIL PEER REVIEW
Peer review for councils
ESEA undertakes biodiversity peer review for Councils in the Greater Sydney Region, with more than 20 review records across biodiversity assessments, stewardship site assessments, and management plans since 2024, covering sites from the Hawkesbury Valley to the Blue Mountains foothills.
