What this is
What is a biodiversity assessment?
What is a biodiversity assessment?
A biodiversity assessment records the habitat types and protected species present near a site, whether planned works will affect them, and what licensing, timing or enhancement measures follow. It runs at development and periodically, and is increasingly required by lenders.
Who carries it out?
An ecologist, engaged directly or through a consultant, competent to identify habitat types and assess species likelihood. A desk-based check by non-specialist staff can flag a concern, but confirming bats or nesting birds needs someone qualified.
What triggers a new assessment?
A new development, a permit requirement, a plant or site change, a complaint, or an incident affecting habitat. It also runs periodically, since habitat and species presence change independently of any planned activity.
Scope
When is a biodiversity assessment required?
This assessment is one step in the environmental management programme, and its boundary with contamination and other instruments matters because a single site visit can otherwise blur what each record is meant to establish.
Use this template when
- A new development, plant change or installation is planned that could affect habitat or species
- A new record is needed; each one gets its own ID in the form BIO-2026-000
- A permit condition, complaint or incident requires the ecological position to be assessed
- The assessment is due at its periodic interval regardless of planned change
- A linked record needs this one to exist: links Site
Do not use it for
- Contaminated Land Record, which records land contamination and monitoring, not habitat or species
- Environmental Aspects Register, the site's general aspects list rather than the survey behind one of them
- Environmental Noise Assessment or Light Pollution Assessment, where those impacts are the primary concern rather than secondary to habitat here
- Waste Stream Register, which tracks material arisings rather than the ground and vegetation nearby
- Anything outside KnowEnviro, which belongs in the workspace that owns that process
Compliance mapping
Which ISO 14001 cl.6.1.2 requirements does this satisfy?
Biodiversity sits inside ISO 14001's aspects-and-impacts requirement, but the sharper duties come from protected-species law, prescriptive about timing and precaution in a way the standard is not.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 14001:2015 cl.6.1.2 | Identification of environmental aspects and their associated impacts, considering a life cycle perspective | Site context |
| UK Conservation of Habitats and Species Regulations 2017, reg.43 | Bat roosts are protected whether or not currently occupied; deliberate disturbance or damage to a roost is an offence | Protected species |
| UK Wildlife and Countryside Act 1981, s.1 | Offence to intentionally kill, injure or take a wild bird, or damage or destroy a nest while in use or being built | Protected species |
| UK Wildlife and Countryside Act 1981, s.14 | Prohibits causing specified invasive non-native species to spread, including through soil or spoil movement | Protected species |
| UK Conservation of Habitats and Species Regulations 2017, reg.9 | Operators near a European protected site must have regard to the site's conservation objectives | Site context |
| ISO 14001:2015 cl.8.1 | Operational controls established to manage significant environmental impacts identified under 6.1.2 | Activities and impact |
| IFC Performance Standard 6 | Biodiversity conservation and sustainable management of living natural resources, applied as lender due diligence criteria | Outcome |
What it does not cover
- Contaminated Land Record, which records known or suspected land contamination and monitoring, not an ecological survey.
- A protected species licence application, a separate regulatory submission this assessment may trigger but does not itself constitute.
- Environmental Noise Assessment or Light Pollution Assessment, where those impacts are the primary subject rather than secondary to habitat identified here.
- The ecological survey report itself, the technical evidence behind the findings, which must exist and be referenced, particularly for season-specific observations.
- Contractor and grounds maintenance instructions, issued separately once the assessment sets what to avoid; it records that briefing is needed, it does not deliver it.
Global
Biodiversity Assessment requirements by country
ISO 14001 sets the general expectation everywhere it is adopted, but the specific, prescriptive duties around timing, roosts and invasive species sit in national wildlife law, where the practical exposure lives.
Wildlife and Countryside Act 1981; Conservation of Habitats and Species Regulations 2017
Nesting birds are protected while a nest is in use or being built; bat roosts are protected whether occupied or not; specified invasive species must not spread.
The most prescriptive of the three on timing and precaution; the form's own field logic, likelihood over confirmation, mirrors it closely.
Endangered Species Act; Migratory Bird Treaty Act
Take of a listed species is prohibited under the ESA; the MBTA prohibits killing or possessing most native bird species without a permit.
Listing status must be checked against federal and state lists, since protection depends on which species are actually present.
ISO 14001:2015; IFC Performance Standard 6
ISO 14001 requires aspects and impacts to be identified and controlled; IFC PS6 sets biodiversity due-diligence expectations for lender-financed projects.
Where finance is involved, PS6-standard evidence is often requested regardless of local law.
How to complete it
How to complete a biodiversity assessment, step by step
The template records a snapshot of habitat, species and planned works. Whether it prevents an offence depends on judgement the fields alone do not supply.
Protected-species law turns on reasonable likelihood, not sighting. Nesting Birds Present or Likely and Bats Present or Likely are worded that way deliberately; answering 'No' without a walkover suited to species and season understates the position.
A survey done in winter finding no active nests says nothing about spring, when works are scheduled. Timing Avoids Nesting Season must be answered against the planned works date, not the survey date.
Identifying an opportunity and implementing a measure are different achievements, and a maintenance plan without both briefing fields answered 'Yes' depends on someone remembering, which is not a plan.
Noise, lighting and discharge assessed as fine for the site can still be material to a designated site within reach, and a below-maximum score there should pull those impact fields into sharper scrutiny.
What auditors find
Most common biodiversity assessment findings
Biodiversity findings are rarely about the ecology being wrong. They are about the gap between what the assessment found and what the people doing the physical work were told.
| Finding | Clause | What fixes it |
|---|---|---|
| Vegetation cleared or a structure altered in nesting season with no survey preceding the works. | UK Wildlife and Countryside Act 1981, s.1 | Require a dated ecological check before clearance, timed to the actual works date, not the assessment's completion date. |
| Bats or nesting birds marked 'No' on a visual check with no survey suited to the species or season. | UK Conservation of Habitats and Species Regulations 2017, reg.43 | Route any building or vegetation due for alteration to a specialist survey rather than a general walkover. |
| Invasive species present but Invasive Species Managed left unanswered with no containment measure recorded. | UK Wildlife and Countryside Act 1981, s.14 | Require a containment or disposal method before any soil movement is authorised near the area. |
| Enhancement opportunities identified but Measures Implemented left blank at the next review. | IFC Performance Standard 6 | Carry open measures into the action record with an owner and date. |
| Maintenance plan marked in place with no briefing fields evidencing it reached the field. | ISO 14001:2015 cl.8.1 | Do not close until both briefing fields are confirmed. |
| Licence identified as required but works proceed before Licence Obtained is confirmed. | UK Conservation of Habitats and Species Regulations 2017, reg.43 | Gate the works instruction on Licence Obtained, since the requirement alone does not permit work to start. |
Case in point
Case in point: the roof that was surveyed in the wrong month
A cold store extension required demolishing an old brick outbuilding. A biodiversity assessment done in November found no bats and no active nests, rated the impact low, and recorded no licence required. The project was approved on that basis and delayed by procurement for four months.
Demolition went ahead in April. Nobody had reconnected the finding to the new date; the roof void, unremarkable in November, was in fact a summer bat roost, and demolition disturbed it. The survey had been correctly answered for the month it was done; it had simply gone stale, and the fix was a rule that any finding older than one active season gets re-checked against the actual works date.

From a document you fill in to a programme that runs itself
The assessment is a snapshot. What prevents an offence is whether its findings reach the person instructing the work on the date it happens, not whether the document itself is accurate.
Holds the biodiversity library against the site portfolio, flags assessments whose works date moved past the surveyed season, and keeps survey evidence attached.
Connects demolition and vegetation clearance permits to this assessment so timing and licensing restrictions are checked before work is authorised.
Tracks licence-required and licence-obtained status so works cannot proceed on the strength of a requirement alone.

Watches project schedule changes for a works date drifted past the surveyed season, and raises the review rather than waiting for the periodic date.

Biodiversity Assessment definitions and key terms
- Reasonably likely to be present
- The legal threshold for protected species assessment in several jurisdictions: protection can apply based on likely presence inferred from habitat, without a confirmed sighting.
- Roost
- A structure or feature used by bats for shelter, protected under UK law whether or not bats are present when it is assessed or disturbed.
- Mitigation hierarchy
- The sequence lenders and regulators expect for biodiversity impact: avoid, minimise, restore, then offset, in that order rather than jumping to compensation.
- Invasive non-native species
- A species specified in law as prohibited from being caused to spread, where the offence can arise from moving contaminated soil rather than only deliberate introduction.
- Biodiversity net gain
- A measurable improvement in habitat value beyond simply avoiding harm, increasingly requested by planning authorities and lenders as an enhancement standard.
FAQ
Frequently asked questions about biodiversity assessment
Do we need to confirm a species is actually present before it is protected?+
No. UK law protects on reasonable likelihood inferred from habitat, and a bat roost is protected whether or not it is currently occupied. Waiting for a confirmed sighting gets the threshold backwards.
How long is a biodiversity assessment valid for once completed?+
Only as long as the season and site conditions it was assessed against. An assessment done outside the active season needs revalidating against the works date, not treated as valid for a fixed period.
Is moving contaminated soil really a biodiversity issue?+
Yes, where it carries an invasive species. Causing it to spread is an offence in itself in several jurisdictions, and it is commonly missed since it is filed under waste rather than ecology.
What does 'high is bad' actually mean for this assessment's scoring?+
Read the individual field scores, not a headline figure: across this form the safer condition, no confirmed bats or active nests, no adjacent designated site, consistently scores highest. Treat a low total as the signal to act on.
Who has to be told if a licence is required?+
The licensing authority before works proceed, and internally whoever holds the contractor relationship; Licence Required 'Yes' has no effect until obtained and instructed.
Does an enhancement measure need ongoing maintenance?+
Yes, almost always. A pond, hedgerow or wildflower area degrades without a maintenance plan, and one without the grounds contractor briefed on areas to leave alone is where enhancement most often fails quietly.
