Zamora Wildfire: 12 Towns Evacuated, 1,000 Flee as Blaze Hits Biosphere

Eleven thousand hectares is the number that matters most in Zamora, and it is hard to picture until you walk it. That is roughly 110 square kilometres of the Arribes del Duero Natural Park burned in three days, a blackened perimeter reported at 75 km, driven by gusts up to 40 km/h ⁸. On a map the perimeter looks like a rough fist around Fermoselle. On the ground it meant flame fronts moving faster than villages could be warned, and a protected canyon landscape burning at the height of summer ²³⁸.

What is established is that the fire broke out on July 29, 2026, in Fermoselle in the Arribes del Duero park in Zamora province, in Castile y León, and grew rapidly with wind and dry fuel ²³⁴. That afternoon the Castile y León environment ministry raised it to level 2, the category for grave risk and imminent danger to populated places ²³. Level 2 is not an administrative detail. It unlocks outside help, puts evacuations on the table, and signals that the fire has moved beyond what local crews can hold ²⁵.

Twelve villages were evacuated and two others, Fermoselle and Fariza, were confined, meaning residents were told to stay inside rather than take the roads ²³. The count was confirmed that evening by RTVE and El País, both reporting 12 evacuations on July 29 ²³. Even the count wobbled in print. El País carried 12 villages in its headline and body while its URL slug said 11 pueblos, a small internal inconsistency that shows how fast the orders were moving that night ³.

The response grew quickly once the level was raised. The UME, the Spanish military emergencies unit, deployed 99 troops and 35 vehicles to Zamora ⁵. The deployment matters because the Arribes country is steep river canyon, hard for ground crews and engines to work, and under extreme heat a fire there can spot across gullies and reappear behind the lines ⁶⁸. By the second day officials were no longer talking about early control. They were talking about survival of villages and getting people back only when the wind allowed ⁴⁶.

July 30 was the day the fire showed what it could do. Specialist weather coverage described a critical phase, with extreme heat, wind and low humidity combining to drive aggressive fire behavior and complicate every advance by crews ⁶. In that kind of air, relative humidity collapses in the afternoon, fine fuels ignite from embers carried hundreds of metres, and night brings little recovery ⁶. The technical extinguishment director Raúl gave a pessimistic assessment on Thursday afternoon, a judgment that matched what was visible on the perimeter ⁴.

By the morning of July 31 the picture had shifted but not ended. The fire remained out of control, with the 75 km perimeter and roughly 11,000 hectares burned and gusts to 40 km/h still testing the lines ⁸. El Norte de Castilla reported that morning that the situation had improved a lot during the night, the first sign that the overnight work had held in enough places to think about returns ⁴. That gap between still out of control and much improved is normal in large fires. It means the worst runs have paused, not that the fire is safe ⁴⁸.

Nowhere captures that night better than Mámoles, a small village that nearly burned. Volunteers and firefighters, including a crew sent from Cádiz, saved the village from 11-metre flames, holding the edge as the fire pressed toward houses ⁹. A resident later summed the fear in the line set large above, saying the feeling was that the village was about to burst into flames ⁹. The detail about Cádiz matters. It shows how far the call for help travelled, with crews moved across the country to defend a hamlet most Spaniards could not place on a map until that week ⁹.

The outcome as of July 31 was partial relief. Residents of 12 of the 14 evacuated localities had been allowed to return, with only Mámoles and Pinilla residents still kept from their homes ⁴⁵⁷¹⁰. The confinements in Fermoselle and Fariza were lifted, ending days in which thousands lived with closed doors and smoke outside ⁴¹⁰. The lifting was overseen through the Integrated Operational Cooperation Center, the joint command structure used when a level 2 fire crosses municipal lines ¹⁰. Telemadrid, citing Europa Press, reported the same Zamora returns alongside parallel progress in Castellón at Vall d2Uixó, where stabilization also allowed evacuations to end ¹⁰¹¹.

The Arribes del Duero designation hangs over all of this. The fire burned inside a natural park and biosphere reserve on the Duero and Tormes canyons, a landscape valued for cliffs, scrub, oak and juniper, birds of prey and traditional terraces ⁸. The upday report on July 31 framed the blaze as a direct threat to the canyons of the Duero and the Tormes while still out of control ⁸. That outlet labelled its illustration as an AI Generated Stock Image, so its perimeter and burned-area figures should be read as reported figures rather than independently verified measurements ⁸. What the Spanish press agrees on is simpler and more important for residents. The evacuation system moved a dozen villages out of the way, the confinement system held two larger towns in place, and by the third day most people could go home ⁴⁵⁷¹⁰.
