Step 1 conclusions: The 60% byelaws claim — what HC 1272 actually says

From FletchWiki

Summary verdict

XX is substantially correct. The government's claim that "around 60% of MPAs already have byelaws in place to prevent damage from fishing activity" is accurate in a narrow, technical sense but deeply misleading in practical terms. It has been described by independent analysts as a "protection myth." The figure counts any MPA with any fisheries management byelaw — including partial, feature-based restrictions covering only a fraction of a site's area — and should not be read as meaning that 60% of MPAs are meaningfully protected from bottom trawling.

1. Where the quote comes from

The quote appears in HC 1272 — which is not the Environmental Audit Committee's own report but the Government's response (4th Special Report, published August 2025) to the EAC's report HC 551, "Governing the marine environment" (published 5 June 2025). It appears in the section headed Marine Protection and Recovery.

The claim is made by DEFRA/MMO, not by the Committee. It is the government's own framing of its partial acceptance of the EAC's recommendation, used to resist calls for a blanket site-wide ban on bottom trawling. The same statistic appears verbatim in the DEFRA MPA Network Report 2019–2024 (published December 2024) — the primary source for the figure — and in a January 2026 letter from DEFRA Parliamentary Under Secretary Emma Hardy to a Conservative MP.

2. What "60%" actually counts

The "60%" figure is drawn from the MMO's byelaw programme, counting any MPA in England (out of 181) in which at least one fisheries byelaw of any kind is in force. This includes byelaws that:

  • restrict bottom-towed gear only over specific designated habitat features (e.g. a reef patch or maerl bed) within an MPA, leaving the rest of the site open to trawling;
  • apply to Stage 1 and Stage 2 byelaws (17 MPAs by end-2024) where bottom-trawl-specific restrictions exist — but only over features, not whole sites;
  • count sites with any fisheries management measure, including those addressing gear types other than bottom trawling.

What "60%" does not mean:

  • Only ~17 of 181 English MPAs (~9%) have byelaws that specifically prohibit bottom trawling (even then, only over designated features, not whole sites).
  • Only 5 of 50 offshore MPAs in English waters had management measures protecting the whole site from bottom-towed gear by end of 2024 (Wildlife and Countryside Link / Wildlife Trusts evidence to the EAC).
  • No byelaw restricts pelagic or midwater trawling — meaning the 1+ million tonnes of pelagic catch inside MPAs (2020–2024) represents entirely unregulated activity even in "byelaw-protected" sites.
  • The government's approach explicitly rejects whole-site bans, which it describes as "disproportionate and not in line with legislation." A byelaw in the 60% count may therefore protect only a small fraction of an MPA's seabed area.

The independent analysis by Ocean Rising (Luke McMillan) labels this the ["The 60% Protection Myth"](https://www.oceanrising.co/p/the-60-protection-myth).

3. Does the Committee challenge this claim?

Yes — implicitly but unmistakably. The EAC's own report (HC 551):

  • Called on the government to ban bottom trawling, dredging and mining outright across offshore MPA boundaries — a recommendation that would be unnecessary if 60% were genuinely protected.
  • Noted the government missed its own commitment to have byelaws for all offshore MPAs "where needed" by end of 2024.
  • Recorded that the three pilot Highly Protected Marine Areas (HPMAs) designated in 2023 still had no byelaws at all, making legal enforcement impossible.
  • Described the 2011 Marine Policy Statement as "outdated, not fit for purpose."

After the Government published HC 1272 rejecting whole-site bans, the EAC Chair reiterated: "We reiterate our recommendation to completely ban bottom trawling within offshore MPA boundaries and ask the Government to clarify how it intends to ensure that a feature-specific approach does not undermine the integrity of MPAs."

The Office for Environmental Protection (OEP) launched a formal investigation into DEFRA in January 2025 for suspected failures to comply with environmental law — specifically, failure to achieve Good Environmental Status of marine waters by the statutory deadline of 31 December 2020.

4. NGO evidence contradicting the 60% claim

Source Key finding Source URL
Oceana UK, The Trawled Truth (May 2025) Only 38 of 377 UK MPAs (~10%) across all UK administrations are fully protected from bottom trawling; 20,600+ hours of suspected bottom trawling inside offshore MPAs in 2024 alone https://uk.oceana.org/reports/the-case-for-banning-bottom-trawling-in-uk-mpas/
Greenpeace UK, All At Sea (July 2024) 92% of UK MPAs have no site-wide regulation against all towed gear; only 8% have complete site-wide closure; 32% (122 MPAs) have no fishing restrictions across the majority of their site https://www.greenpeace.org.uk/news/all-at-sea/

5. Enforcement

The government (HC 1272 and MMO blog posts) presents enforcement as adequate:

  • Since March 2024, the MMO has analysed VMS data for all vessels >12m using bottom-towed gear in English waters.
  • Of 524 such vessels, 66 (12.6%) were detected breaching byelaws — some cases under prosecution.
  • First-ever MPA byelaw prosecution: May 2025, guilty plea, £40,000 financial order.
  • Second prosecution: January 2026, illegal bottom-towed fishing in Offshore Brighton MCZ.

Critical context:

  • 12.6% is a high breach rate, not a low one — approximately 1 in 8 vessels fishing with bottom-towed gear was found in violation.
  • Much of the 20,600+ hours of bottom trawling inside MPAs in 2024 was legal activity in the 83%+ of MPAs with no bottom-trawl ban — not enforcement failure but absence of law.
  • The three flagship HPMAs still had no byelaws as of the inquiry, making any enforcement there impossible.
  • The government missed its own 2024 commitment on byelaw coverage.

6. The "38 out of 377" figure — source

The "38/377 fully protected" figure cited in the ChatGPT summary shared by XX comes from Oceana UK's "The Trawled Truth" (May 2025). It covers all UK MPAs across all four administrations (377), using a stricter definition: the MPA must have legally enforceable measures prohibiting bottom trawling across the whole site (or all qualifying habitat). It is therefore on a different denominator (UK-wide 377) from the government's 60% claim (England-only 181) and uses a more demanding definition of "protected."

Both figures can be simultaneously accurate — but together they reveal the gap between nominal designation and substantive protection.

7. Verdict on the TCP/XX dispute

Position Assessment
TCP: "60% of MPAs have byelaws in place" Technically accurate but substantially misleading — this is what the government said, and the government is the source TCP read
XX: "This claim is brazen and disingenuous" Correct in substance. Only ~9% of English MPAs have bottom-trawl-specific byelaws; only 5/50 offshore MPAs have whole-site protection. The 60% figure conflates partial feature-based measures with meaningful protection.
XX: "With the exception of 2–3 MPAs, they are all trawled" Consistent with the data. 20,600+ hours of bottom trawling inside offshore MPAs in 2024; 1.347m tonnes caught 2020–2024.
TCP's question: "Is the 60% inconsistent with 38/377 being fully protected?" No — they measure different things (England-only vs. UK-wide; any-byelaw vs. whole-site ban). Both can be true simultaneously.

The core finding: the government's "60%" claim counts feature-based partial restrictions as "protection," while the NGO figure of ~10% counts only MPAs with whole-site bans on bottom trawling. The government definition is technically defensible but practically misleading, and the EAC, Oceana, Greenpeace, the Wildlife Trusts and the OEP all effectively say so.
