All Cumberland’s ecologists are well-versed in Biodiversity Assessment Method (BAM), required when working with the NSW Biodiversity Conservation Act (BC Act). We also have 11 accredited in-house BAM assessors.

Cumberland’s expert team has carried out a wide variety of large and small BAM projects since the BC Act started, including matters assessed by the NSW Land and Environment Court (LEC).

We have an in-depth knowledge of State and Commonwealth environmental legislation and deep experience in its application across a multitude of real -life situations, giving our clients confidence they are receiving pragmatic, astute and efficient advice.

Some project highlights are:

The ongoing eight-year survey and analysis of threatened flora and fauna on Groote Eylandt in the Gulf of Carpentaria.
Cumberland has overseen nine ecological expeditions through the megadiverse tropical rainforests of the Philippines.
Expert analysis of impacts to critically endangered temperate grasslands and Snow Gum woodlands in the NSW Snowy Mountains.
❖ Providing thousands of hectares of new habitat for native species through development and management of biodiversity offsets.

Land and Environment and Federal Court – Expert Witness

Since its beginnings in 2003, Cumberland Ecology has delivered more than 5000 environmental projects across Australia and overseas, with many requiring astute negotiation and final resolution and approval from the court.

Cumberland’s strong reputation for excellent expert testimony has delivered our clients successful outcomes in many Land and Environment Court and Federal Court cases.

Our ecological consultants are experienced in preparing for, and managing LEC proceedings for Class 1, Class 3, Class 4 and Class 5 matters.

We stand ready to guide your business through the complexities of ecological assessments in court, working closely with your legal counsel.

Cumberland Ecology’s Director Dr David Robertson is a highly experienced and sought-after expert witness with 35 years of ecology experience since obtaining his doctorate at Melbourne University in 1985.

Dr Robertson is also a key opinion leader in government and court-related environmental work and has a special interest in threatened species impacts, ecologically sustainable renewable energy solutions, terrestrial and aquatic monitoring, and surveying.

Biodiversity and
Renewable Energy

The tension between human growth and sustainability has never been more apparent with the visible onset of climate change and increasing global population challenges.

Climate-driven natural
disasters underscored 2020 in Australia

This is when Australia lost 3 billion animals as wildfires scorched almost 20 million hectares of land.

Australia has the fourth highest level of animal species’ extinction

Today 30% of the world’s entire global mammal extinction has occurred right here in Australia.
