Read the Report Before You Write the Letter: A Naturalist's Field Guide to Fighting a Bad Planning Application

We've all had that moment. Someone shares a planning application on the local Facebook group: forty houses, a car park, and — sitting right in the middle of it — the barn where you've watched brown long-eared bats emerge every summer since 2019. Your blood pressure spikes. Your fingers hover over the keyboard.

Stop. Breathe. An angry objection saying "I love bats, don't build here" will be weighed, noted, and dismissed. A well-constructed one, grounded in law and evidence, can stop a development or force a redesign. Here's how to write the second kind.

Understand What Planners Can Actually Refuse

Here's the uncomfortable truth: bats don't have an absolute veto over development. What they do have is strong legal protection under the Conservation of Habitats and Species Regulations 2017 and the Wildlife and Countryside Act 1981, plus policy protection through the National Planning Policy Framework (NPPF), which requires planning authorities to refuse applications that would harm protected species unless there are "imperative reasons of overriding public interest" and no alternatives.

What this means in practice: your objection needs to argue that the application, as submitted, fails to demonstrate legal compliance or proper survey effort. You're not asking the council to like bats better than housing. You're pointing out that the paperwork is legally deficient.

Get the Documents — and Actually Read Them

Every planning application is available on your local authority's planning portal — Stockton, Redcar & Cleveland, Middlesbrough, Hartlepool, all of them. Search the reference number, download the Ecology Survey / Preliminary Ecological Appraisal (PEA), and read it properly.

Things to look for:

• The date. Bat surveys are only valid for around 12–18 months. An ecology report from 2022 for a 2025 application is not evidence of current roost status.
• The season. Dusk emergence surveys can only be conducted May to September, with the core window in June–July. A "survey" conducted in March or October is essentially worthless for roost confirmation.
• The number of visits. If an initial PEA flags bat potential, standard practice requires multiple dusk and dawn surveys. One visit is not adequate. If the report says "a single emergence survey was undertaken", that's a red flag you can cite.
• Access limitations. "The loft space could not be accessed" appears more often than it should. Inaccessible areas must be flagged and followed up — if they weren't, say so.
• The word "likely". Vague hedging like "the building is unlikely to support roosting bats" without supporting survey data is exactly the kind of assertion Natural England challenges.

The Step-by-Step Objection Checklist

1. Find the deadline and the reference number. Late objections may not be considered.
2. Gather your evidence. Your own records count — dates, times, species if you know them, photos of droppings or emergence counts. Submit them to your Local Environmental Records Centre (ERNEC covers much of Teesside) so they're on the official record.
3. Check the ecology report against the list above and note specific deficiencies, quoting page numbers.
4. Cite the law and policy: Habitats Regulations 2017, NPPF paragraphs on protected species, and your local plan's biodiversity policies.
5. Propose solutions, not just objections. Alternative layouts, retained roost features, lighting plans with lux limits — objections that suggest workable fixes are harder to dismiss as NIMBYism.
6. Keep it factual and concise. Two pages of precise, referenced argument beats ten pages of outrage.
7. Submit through the portal, so your comment is formally logged, and copy your ward councillor.

A Case Study: Stockton Gets It Right

In 2023, a housing application off the northern edge of Stockton proposed demolishing a disused agricultural building. The submitted ecology report contained a single dusk survey conducted in late April — outside the core season — and concluded the building had "low suitability".

Local naturalists, coordinated through a community WhatsApp group, did three things. They submitted years of personal records showing pipistrelle and brown long-eared activity. They quoted the survey guidelines (the Bat Conservation Trust's Bat Surveys for Professional Ecologists: Good Practice Guidelines) showing the survey was non-compliant. And they proposed an alternative: retain the building as a converted barn with an integrated roost and a lighting scheme capped at 1 lux along the boundary hedgerow.

The result? The applicant withdrew, resurveyed properly in June, found a maternity roost of soprano pipistrelles, and returned with a revised scheme that retained the building and incorporated a dedicated roost area. Not a total victory — the development went ahead — but a maternity roost that would have been bulldozed now persists, monitored annually.

The Long Game

Even when you lose, well-argued objections build a paper trail. They make councils more likely to attach proper conditions, make applicants take surveys seriously next time, and demonstrate that Cleveland's naturalists are watching. Join your local bat group, submit your records, and turn up to planning committees when it matters. The bats can't speak at the podium. You can.
