US Fish and Wildlife Service Downlists Rough Popcornflower and Adopts ESA Section 4(d) Rule

US Fish and Wildlife Service has finalized a Federal Register rule downlisting the rough popcornflower from endangered to threatened under the Endangered Species Act and establishing a species-specific section 4(d) rule effective 18 June 2026. The species remains conservation reliant, so developers and land managers in its Oregon range must continue to treat it as an ESA-listed plant, with strict controls on removal and commerce and ongoing consultation risk for projects affecting its wetland habitats.

Michigan HB 5536 Proposes Revised Wetland Definitions and Local Ordinance Rules

Michigan is considering HB 5536, a bill that would amend the state’s Natural Resources and Environmental Protection Act to revise how “wetland” is defined and how local wetland ordinances and inventories are structured. If enacted, the new criteria and governance rules would change how developers, landowners, and local governments in Michigan determine which areas require wetland permits and how state and local approvals are coordinated.

EU Adopts Forest Reproductive Material Regulation on Production and Marketing of FRM

The EU has adopted a new Forest Reproductive Material Regulation creating a harmonised framework for the production and marketing of forest seeds and planting stock, replacing the 1999 directive and amending the plant health and official controls regimes. Forestry and nursery operators across the EU will face stricter approval, traceability, labelling and import requirements for FRM and should plan multi‑year adjustments to sourcing, certification and data systems ahead of application five years after entry into force.

Brazil Chamber Approves Bill Redefining Jamanxim National Forest Boundaries and Creating Jamanxim APA

In May 2026 Brazil's Chamber of Deputies approved bill PL 2486/2026 redefining the Jamanxim National Forest in Pará, carving out a large Environmental Protection Area and enabling controlled mining and other land uses, and sending the measure to the Senate. If enacted, this would materially weaken protection of a strategic Amazon conservation area while reshaping land regularisation rules, raising deforestation, biodiversity and ESG risks for operators, investors and supply chains linked to the region.

Brazilian Chamber Committee Approves Biotechnology Research Programme For The Legal Amazon

A key committee of Brazil’s Chamber of Deputies has approved a substitute text for Bill 411/2025 to establish a national programme that funds biotechnology research based on Legal Amazon biodiversity, with mandatory participation of Indigenous and traditional communities, alignment with the National Bioeconomy Development Plan, and explicit linkage to Brazil’s Biodiversity Law on access and benefit-sharing. If enacted as drafted, the programme would channel public support and safeguards into Amazon-focused biotech R&D, shaping how research institutions and biotech and pharma companies design projects, partnerships and benefit-sharing arrangements in Brazil over the coming years.

Germany: Greens Motion Proposes Night-Time Operating Ban And Certification Rules For Robotic Lawnmowers

In May 2026, the German Greens tabled a Bundestag motion to mandate daytime-only operation and wildlife-safety certification for robotic lawnmowers, which has now been referred to the Committee on Nature Conservation. If translated into law, manufacturers would need to redesign products and firmware, deliver free updates for connected legacy devices by 2027, and plan for hedgehog-safety certification as a market access condition by 2030.

CJEU Advocate General Kokott Clarifies SEA Obligations for S1 Vienna Outer Ring Express Road (Case C-189/25)

On 21 May 2026, CJEU Advocate General Kokott issued an opinion in Case C-189/25 arguing that Austria’s amended route-designation law for the S1 Vienna Outer Ring express road should have been subject to strategic environmental assessment under Directive 2001/42/EC and that omissions at this level can later destabilise downstream permits. If followed by the Court, this would materially raise legal risk for major infrastructure projects whose underlying plans or route choices were modified without SEA, as national authorities could be required to suspend or revoke long-standing consents unless an equivalent assessment has already rectified the gap.

Norwegian Environment Agency Adopts New Catch Reporting Rules for Anadromous Salmonid Fishing

In May 2026, the Norwegian Environment Agency adopted a new regulation tightening digital catch reporting and gear registration requirements for anadromous salmonid fisheries in Norway. The phased move to weekly and continuous electronic reporting from the 2026 and 2027 seasons will force fishers and river managers to modernise systems, while giving authorities better real-time data to safeguard salmon stocks and adjust rules quickly.

US NOAA Seeks Comment on Supplemental Programmatic Environmental Impact Statement for Coral Reef Conservation Program

NOAA has launched a supplemental programmatic environmental impact statement under NEPA for its Coral Reef Conservation Program and is seeking public comment by mid-June 2026 on the scope, alternatives, and new restoration and conservation methods to be evaluated. The outcome will steer future design, scale, and mitigation expectations for coral reef conservation, restoration, and watershed projects across multiple U.S. coral jurisdictions, so agencies, grantees, and other stakeholders may wish to engage early to influence priorities and safeguards.

UNECE Draft Decision X/4–VI/4 on Mediterranean Cooperation Under the Espoo Convention and SEA Protocol

UNECE has issued a draft decision for its June 2026 Working Group meeting that would formalise Mediterranean-region cooperation on transboundary environmental and strategic impact assessments under the Espoo Convention and its SEA Protocol for the 2027–2029 workplan. If adopted, this will push Mediterranean governments and multilateral lenders towards more systematic, harmonised scrutiny of large marine and coastal projects, strengthening links to the Barcelona Convention and the emerging high seas biodiversity regime without yet creating direct new obligations for companies.

Minnesota Publishes 2026 Noxious Weeds Guide With Ornamental Phase-outs

Minnesota has issued a 2026 noxious weeds guide that consolidates statutory weed categories and highlights new 2026–2028 phase-out schedules and trade restrictions for several invasive ornamental species. Nurseries, garden centres and land managers in Minnesota must plan now to stop producing, selling and planting affected species, update labeling and procurement, and prepare for full sales and propagation bans taking effect after the 2028 phase-out window closes.

Delaware Senate Finance Committee Reports SB 9 (Wetlands Stewardship Act) Out Of Committee

Delaware’s Senate Finance Committee has reported SB 9 (Wetlands Stewardship Act) out of committee, advancing a state wetlands permitting programme that would cover tidal and nontidal wetlands and require DNREC to build a new regulatory framework. If enacted, the bill would shift more oversight from federal Clean Water Act jurisdiction to Delaware, expanding permitting and mitigation obligations for projects affecting wetlands while creating new exemptions and general permits, so land developers, utilities, agriculture and other land‑disturbing operators should start assessing future permitting and timing risks.

DNREC Releases 2026-2030 Delaware Wetland Program Plan

Delaware’s environment department has issued a voluntary 2026–2030 Wetland Program Plan that sets priorities for monitoring, restoration, regulatory work, and public outreach on wetlands statewide, aligned with U.S. EPA’s core elements for wetland programmes. The plan does not itself create new permit deadlines, but it signals DNREC’s strategic focus for the next five years and highlights the importance of pending legislation such as Senate Bill 9, which would establish stronger freshwater wetland protections and future compliance expectations.

Canada Applies SARA Critical Habitat Protection to Channel Darter (Lake Erie Populations)

Canada has brought into force a Species at Risk Act order that applies the section 58(1) prohibition on destruction of critical habitat to the Channel Darter Lake Erie populations from 4 May 2026. This materially tightens federal controls on in‑water works in key stretches of the St Clair–Detroit River corridor and western/central Lake Erie, so projects there must now factor SARA/Fisheries permitting risk and potential design changes into planning.

Dutch Minister for Agriculture Clarifies Natural Nitrogen Sources and AERIUS Updates for Wadden Area

In May 2026 the Dutch Minister for Agriculture answered detailed parliamentary questions on nitrogen deposition in the Wadden area, clarifying that natural nitrogen sources such as seabirds and "ammonia from sea" form only a small share of total emissions and are already factored into Natura 2000 assessments and AERIUS modelling. The response signals that no additional "ammonia from sea" changes are planned in upcoming AERIUS updates, so permit calculations and legal exposure for activities like farming and shrimp fisheries will continue to hinge primarily on reducing anthropogenic nitrogen emissions rather than reclassifying natural background loads.

Mexico Semarnat Announces It Will Not Approve Royal Caribbean "Perfect Day" Project in Mahahual

In May 2026 Mexico’s environment minister Alicia Bárcena announced that Semarnat will not approve Royal Caribbean’s proposed “Perfect Day” mega‑tourism project in Mahahual, Quintana Roo, citing environmental impact concerns. This effectively signals a likely denial of environmental impact authorisation for the project and highlights tougher scrutiny of large coastal tourism developments in fragile Mexican ecosystems, raising permitting and reputational risks for similar investments.

France: Toulouse Administrative Court Orders City To Enforce Nighttime Lighting Rules For Shops

A 2026 judgment by the Toulouse Administrative Court orders the city to enforce France’s light‑pollution rules by formally notifying 30 non‑compliant commercial establishments to switch off night‑time lighting. This precedent signals growing legal pressure on municipalities to police energy‑wasting and biodiversity‑harming lighting, raising enforcement risk for retailers and other operators that ignore national switch‑off requirements.
