Whose Land Is Burning? A Firefighter’s Worst Nightmare in Portugal

Portugal’s firefighters can only do so much. Year after year the biggest barrier they name is not water, helicopters or budgets, but simply knowing who owns the fuel-filled plots where flames take hold. Despite a raft of reforms, 2025 has again exposed how missing names on title deeds translate into slow prevention work, expensive emergency interventions and spiralling insurance claims.

The Ownership Puzzle Behind the Flames

The country’s countryside is famously fractal. Millions of micro-parcels—many no larger than a tennis court—dot hillsides from Trás-os-Montes to the Algarve, reflecting centuries of inheritance customs known as minifúndio. When heirs scatter abroad or lose track of paperwork, the land is left unmanaged, under-insured and increasingly combustible.

Officials estimate that roughly 30 percent of Portugal’s 11.7 million rural plots sit inside unresolved estates; nobody is authorised to cut trees or clear brush, yet everybody pays when a spark turns into a firestorm.

2025: A Hard Deadline for Mapping the Countryside

Lisbon’s response is the Balcão Único do Prédio, or BUPi—an online one-stop shop that lets owners georeference property for free until 31 December 2025. The service now covers 155 municipalities lacking an older cadastral map, and justice-ministry figures show 2.4 million plots uploaded so far, about one-third of the area targeted.

The government’s broader Forest Intervention Plan wants 40 percent of all rural deeds accurately mapped by New Year’s Eve, arguing that clear boundaries unlock insurance, investment and safer woodlands.

North and Centre Still in the Dark

Progress is uneven. Mountain districts such as Viseu, Guarda and Castelo Branco—where 2017’s catastrophic fires killed more than 100 people—remain the least documented. Many locals migrated decades ago, leaving heirs unaware they even own land. Without coordinates in the national system, municipal officers cannot issue formal notifications to clean plots, and police cannot levy fines.

Enforcement Season Starts After 15 June

This spring the government again pushed back the annual vegetation-clearance deadline—first to 31 May, then to 15 June—because of heavy rains and labour shortages. From 16 June the GNR’s environmental branch began daily patrols, already flagging over 10 400 suspect parcels. Fines range from €140 to €5 000 for individuals and up to €60 000 for companies, though commanders say they apply “bom senso” when tractors and crews are hard to find. If the owner cannot be located, councils post a notice on site for five days; after that the municipality may hire contractors, then bill the absent proprietor.

New Money for Active Management

Alongside sticks come carrots. The “Floresta Ativa” fund, launched in June with six million euros, offers grants of €650 per hectare for solo owners and €800 for collective bids covering pruning, fuel breaks and native-species replanting. Integrated Landscape Management Areas and long-standing Forest Intervention Zones also receive fresh support, though foresters warn that none of these schemes will succeed without clearer land records.

What Foreign Residents and Buyers Need to Know

Many expatriates are drawn to stone farmhouses and olive groves at bargain prices. Owning rural land brings a legal duty to maintain a 50-metre buffer around homes and a 100-metre strip around villages or tourism sites. Failure can void insurance and lead to steep penalties. New buyers should verify that their deed is georeferenced in the BUPi or the older cadastral registry; if it is not, the process is free until the end of the year but becomes paid—and potentially contentious—thereafter. Lawyers also advise checking for undivided heirs who may still hold rights.

Looking Past 2025

From 2026 the state may begin taking custodial control of parcels without an identified owner, starting with fire-prone priority zones. Officials hope that threat will spur the remaining hold-outs to update records, but admit the task is generational. Until then every summer will hinge on whether the undergrowth has been trimmed in places nobody is sure belong to anyone at all.
