Dave Bentley Ecology Services, established in 1991, is an ecological consultancy specialising in wetland ecology.
The consultancy is provided by Dave Bentley who is the most experienced wetland ecologist working in consultancy in North West England. He has been organising nature conservation work in Greater Manchester since 1983.
All wetland survey and evaluation work undertaken by the consultancy is conducted solely by Dave Bentley and thus by hiring Dave Bentley Ecology Services you are guaranteed to have all his skills, experience and knowledge at your disposal (refer to Expertise Page).

Our main work (examples of which can be found on the Clients Page), expanded upon below, has two strands:
- Survey and Evaluation including -
Terrestrial, marshland, running water and still water Invertebrate Surveys
Survey of habitats and protected species
Invasive plants surveys (Knotweeds, Giant Hogweed, Himalayan Balsam, other Schedule 9 plants, and invasive feshwater alien plants)
Environmental Impact Assessment
Planning submissions in support of development
Planning rebuttal in opposition to development
Planning appeals and Expert Witness
Local Authority Forward Planning Work
Independent Appraisals or Second Opinions

Countryside Access work
Survey and Evaluation
- Habitat description
- Habitat mapping e.g. pond plans
- Botany, including mosses, and NVC and rare/protected species (e.g. Floating Water-plantain Luronium natans)
- Terrestrial invertebrate surveys
- Aquatic invertebrates (an identification service is also available from us)
- Mud Snails (Omphiscola (Lymnea) glabra)
- Crayfish - White-clawed Crayfish and the alien American Signal Crayfish
- Lesser Silver Water Beetles (Hydrochara caraboides)
- Lancashire Pond Biodiversity Survey
- Water Voles, Water Shrews and Otters
- Amphibian assemblages
- Great Crested Newt single visit surveys
- Great Crested Newt surveys in July, August and September by looking for larvae and other habitat indications
- Great Crested Newt population studies
- Stream kick sampling surveys (BMWP+ and Bullhead fish)
- River Corridor Surveys
- Waterside birds such as Little Grebe, Reed Bunting and Sedge Warbler
- Wide range of related terrestrial surveys as set out below
Our unparalleled experience in amphibian surveys and pond ecology evaluation allows us to complete presence/absence surveys for protected or special pond species - Great Crested Newts, Lesser Silver Water Beetles, Mud Snails and Water Voles - in a single visit by one field worker e.g. at some sites we have located more than 20 clustered Great Crested Newt "new" breeding ponds in a single day. Comparison with others' work has shown our use of our skills and knowledge locates more protected species sites than do expensive multi-method multi-visit approaches where the client pays for adherence to a methodology rather than skill. Ponds which are difficult to survey using torchlight or bottle-traps often fail to reveal the presence of legally protected newts. False negative results can cause extreme delays for construction companies once the error is discovered. Our 100% reliable blanket surveys are used to give rapid answers to urgent questions. N.B. More work is sometimes needed to satisfy planners and Natural England when applying for planning consent or licences, and in this case blanket surveys are often unavoidably accompanied by multi-method multi-visit methodologies. If we feel we have done enough work to know the answers we were seeking through the surveys we were doing for our clients then we do our best to persuade the decision makers to allow us to stop. We do not want to waste our clients money trying to answer a question we have already answered. Repeat visits allow for an estimation of population though add nothing to presence/absence data.
The Lancashire Pond Biodiversity Survey Methodology is required for all ponds which may be directly affected by developments in Lancashire County - it involves a single visit by a single surveyor encompassing habitat description, habitat mapping, botany, hydrology, aquatic invertebrates (including rare and protected species), amphibians including Great Crested Newts, waterside birds and mammals such as Water Voles, Water Shrews and Badger setts in steep pond banks. The methodology is equally useful in any county. Dave Bentley has completed 1168 of such surveys.
Breeding Bird and Bat surveys can also be arranged using our network of associated specialists.
During our torchlight pond surveys we record Bat species encountered e.g. Pipistrelles and Daubentons Bats as a matter of course.
