ACD provides a full suite of ecological services to support its clients through the planning and development process. The preliminary ecological input typically comprises an extended Phase 1 habitat survey of the proposed development site alongside a desk study. This ecological assessment work allows us to inform our clients of any (actual and / or potential) legal and / or planning policy constraints in relation to ecology and their proposed development(s).


Ecological constraints such as the presence of protected/notable species, for example; roosting bats, great crested newt, dormouse, reptiles and badgers, are material considerations in the planning process and may require further survey work and/or mitigation.

Other constraints which would be identified comprise the presence of invasive species, specifically invasive weed species listed on Schedule 9 of the Wildlife and Countryside Act (1981) such as Japanese Knotweed and Giant Hogweed.

Section 14(2) of this Act states that it is an offence to ‘plant or otherwise cause to grow’ in the wild any species listed on Schedule 9. This could include spreading parts of the plant around a development site during site clearance or whilst undertaking construction works.

In addition, Japanese Knotweed is regarded as controlled waste and has to be disposed of at licensed sites or by burning on site. Establishing the presence of such species enables us to inform our clients of any likely mitigation requirements.

ACD’s primary piece of advice to its clients is therefore to commence the ecological assessment work at the earliest opportunity, preferably at the pre-application stage.

ACD have a team of experienced ecologists who specialise in protected species and habitat surveys. We are experienced at producing management plans for sites that vary in complexity and size. Our ecologists have particular specialisms in badgers, bats, invertebrates, dormouse, barn owls, otters and water voles. Our Principal Ecologist Nicholas Jones, is one of a small number of ecologists who is a Registered Consultant under the Bat Low Impact Class Licence and our Ecology Director Daniel Wood is a Registered Consultant under the badger class licence.

A number of our ecologists are experienced botanists who conduct National Vegetation Classification surveys of various habitat types, including woodland and grassland. We regularly prepare detailed habitat creation and long term management plans and are adept at using biodiversity impact calculators to demonstrate a biodiversity net gain.

Our ecologists hold Natural England class licences for bats, dormouse, great crested newt, barn owls and are members of the CIEEM.

Did You Know?

The word ‘badger’ comes from the 16th century earlier word bageard, possibly referring to the white mark on their forehead reminiscent of a badge.

Badgers live underground in a maze of tunnels and chambers known as ‘setts’. It is thought that these setts can survive for centuries.

Badgers (Meles meles) are not only found in the UK but also in China and Japan.

Badgers are protected by the Protection of Badgers Act 1992. This means disturbing or damaging setts, killing, injuring or taking a badger are illegal with stiff penalties.

Recently the guidance on badgers and proximity of working near badger setts, has changed. The need for a licence to work near a badger sett is now based on an ecologist’s professional opinion, and not the measured 10m, 20m and 30m exclusion zones as before.

Ecology Survey Season

In light of the complexity of the various ecological survey seasons, ACD would welcome the opportunity to discuss with its clients the programming of any ecological assessment work for the current season.
