Checking an ecologist's membership and competence

Choosing an ecologist for a planning application is a competence decision with legal consequences. Some ecological work can only lawfully be carried out by a person holding a licence, and some reports will be rejected by the local planning authority because the author was not suitably qualified for the survey type. Membership grade is the starting point rather than the answer.

The professional body for ecologists and environmental managers operates graded membership with an associated code of professional conduct, and separate chartered registrations sit above it. None of those grades certifies competence for a particular species or habitat, which is the thing you actually need to check.

The membership grades and what each signals

Graded membership runs from student and graduate levels, through a qualifying grade for those working towards full membership, to associate and full membership, with a fellowship above. Full membership requires assessed professional experience, and it is the grade most authorities expect to see behind a report on anything beyond a simple appraisal.

Chartered status is a separate, higher hurdle. A chartered ecologist has been assessed against a defined competence framework and is subject to continuing professional development requirements and a disciplinary process. Chartered environmentalist registration covers broader environmental practice.

What these tell you is that someone has been assessed and is accountable to a body with a complaints procedure. What they do not tell you is whether that person has ever surveyed a barn for roosting bats or identified a lowland meadow in the field.

So check the grade, then set it aside and ask the harder questions.

Competence for the specific survey

Match the person to the work rather than to the project.

A preliminary appraisal covering habitats and the potential for protected species is generalist work, and full membership plus local experience is normally sufficient. A Preliminary Ecological Appraisal written by someone who has walked hundreds of sites in the county is worth more than one written by a specialist in a single taxon.

Species-specific survey is different. Bat emergence and re-entry surveys, great crested newt surveys, dormouse work, water vole and otter surveys and badger work each have their own methods, seasons and licensing positions. Ask which of these the individual attending site has personally led, in the last three seasons, and how many.

Licensable work is different again. Surveys that involve disturbing a protected species, entering a roost or setting traps require the surveyor to hold a licence from the statutory nature conservation body under the relevant wildlife legislation. That licence is personal to the holder, so the question is not whether the consultancy holds licences but whether the person on site does, and at what level. A Protected Species Survey and any subsequent mitigation licence require a suitably licensed ecologist as a matter of law, and no draft document substitutes for that.

Biodiversity net gain work is its own competence. The statutory metric under the Environment Act 2021 expects a competent person to complete it, and habitat condition assessment in particular rewards field experience. Errors in condition scoring change the unit figures materially, and they are not obvious to a reviewer working from the spreadsheet alone. The report sits at Biodiversity Net Gain Assessment.

Habitat and geography

Ask what the ecologist has surveyed within 30 miles in the last two years, and which habitats.

Local experience matters more in ecology than in most disciplines, because it brings knowledge of the local records centre, the county recorders, the local wildlife sites system, the relevant nutrient or recreational impact issues and the authority's own ecologist. An ecologist who knows which local wildlife site designations the council applies will produce a report that answers the council's questions.

Habitat experience matters for a different reason. Botanical survey competence varies widely, and condition assessment for net gain purposes depends on it. Ask directly whether the person doing the field survey can identify grassland indicator species without a key.

Reading a method statement for competence signs

The method statement tells you more than the CV.

1. Does it name the survey seasons and tie them to the proposed programme, or does it promise results in any month?
2. Does it state survey effort, such as the number of visits and the conditions required, rather than referring generally to standard methods?
3. Does it name the source of the desk study data and say whether a records centre search has been commissioned?
4. Does it say what happens if a protected species is found, including the licensing route and the programme consequence?
5. Does it state the limitations, including seasonal constraints and access restrictions?
6. Does it name the individual attending, their licence level where relevant, and who will sign the report?

A statement that promises a bat survey in January without explaining that it can only be a daytime building inspection at that time of year is the clearest warning sign in the field.

Survey seasons set the programme, not the other way round

Most ecological survey work is seasonally constrained, and the constraint is biological rather than administrative. Bat emergence surveys run through the warmer months, amphibian surveys through the spring breeding period, breeding bird surveys across a defined spring and early summer window, and botanical survey when plants can be identified in the field.

An ecologist who agrees to deliver out-of-season results is either planning to caveat the report heavily or planning to overstate what the survey shows. Either way the council's ecologist will see it, and a holding objection follows.

The practical answer is to commission the preliminary appraisal as early as possible, so that the survey requirements are known before the programme is fixed. On a site with a barn, mature trees or a pond, that appraisal should be the first thing commissioned after the site is acquired, ahead of the architect.

Where the season has already been missed, the honest routes are to wait, to design on a precautionary basis that assumes presence, or to seek the authority's agreement to a condition. Which of those is available depends on the species and on the authority, and it is a conversation worth having before an application is submitted rather than after.

Professional codes and what they do to a report

The code of conduct requires members to work within their competence, to report findings honestly and to have regard to the public interest and to biodiversity. Those obligations have practical consequences you should expect to see.

An ecologist bound by the code will refuse to write a conclusion the survey does not support, will record negative findings, and will say when a survey is out of season. That occasionally produces an answer clients do not want. It also produces a report that survives scrutiny from the council's ecologist, which is the point.

The same independence questions that apply across planning evidence apply here, and they are set out in independence and conflicts of interest in planning evidence.

Insurance, liability and quotations

Check professional indemnity insurance level and that it covers ecological advice specifically, not merely general consultancy. Check whether the cover is claims-made and what happens if the firm dissolves.

In a quotation, four things should worry you.

A price materially below the others, with survey visits reduced to a number the method cannot support. A programme that ignores survey seasons. An exclusion of the records centre search, which then arrives as a variation. And a scope that stops at survey without covering the mitigation design, licensing support or the biodiversity gain plan, leaving you to appoint again mid-application.

Ask for the deliverables list and the assumptions in writing, and compare those rather than the totals. The approach to setting that scope is covered in writing a brief for a specialist planning report.

PlanScope drafts ecology-related planning documents to a policy-aware structure and flags missing site facts rather than inventing them. Surveys, licensing and the statutory metric remain work for a licensed or competent ecologist, and the draft is a starting point for that professional rather than a substitute.

For specialist technical reports, qualified professional input may be required.
