Overview of Arbor Ecological

Our ecologist and arborist works range from single tree assessments for home owners to development assessments such as construction of the Pacific Highway and residential housing developments and subdivisions. Many of our projects combine professional ecologist and arborist tree surgeon services.

Our clients include land developers, owner builders, private landholders, local councils, State Government agencies, development and planning firms, and fellow environmental consultants. We work mostly in the NSW North Coast in Northern Rivers centres such as Ballina, Lismore, Lennox Head, Byron Bay, Bangalow, Brunswick Heads, Murwillumbah, Mullumbimby, Tweed Heads, Kyogle, Casino, Evans Head and Grafton.

Our ecological services include flora and fauna impact assessments, vegetation and threatened species management planning, spotter catcher and pre-clearing assessments, and installation of wildlife fauna nest boxes.

Our arborist tree surgeon services focus on tree health, condition, risk and tree impact assessments.

We have experience and expertise in preparation of development arborist reports, ecologist reports and conservation management plans. Field assessments and reports are completed on time and within budget and we draw on the expertise of colleagues with specialist skills to meet client needs as required. Arbor Ecological is committed to ethical practices and professional standards.

From individual tree assessments to large scale ecological assessments for developments, we deliver high quality and affordable ecologist and arborist tree surgeon services.
