Efforts to extinguish the fire in the Odiel Marshes, which originated from a resurgence of the fire that occurred last Sunday in the Burro Marshes, continue this Wednesday. The fire, which is contained but has two active fronts, has been generating a considerable amount of smoke affecting the city of Huelva and its surrounding areas.

It is warned that the smoke will be "very perceptible" throughout the day due to the vegetation and wind. The director of COP Infoca Huelva, Alejandro López, stated that although the fire "does not pose a significant risk of propagation," the smoke will persist. It is recommended to close doors and windows and protect vulnerable individuals such as the elderly, children, and those with respiratory illnesses, suggesting the use of masks.

Assigned resources for firefighting include, on the ground, a team of forest firefighters, an operations technician, an environmental agent, and a fire engine, in addition to two aerial resources. External conditions such as tides and winds hinder operations, especially in the southern zone, which is inaccessible by land, where the vegetation promotes slow and persistent combustion.

The fire reignited due to strong winds that caused a new focus, affecting areas with eucalyptus sprouts, reeds, and pasture. The large amount of smoke in Huelva city is explained by the abundant espartina grass and organic matter in the marsh, as well as plant debris carried by the Odiel river.

The main current challenge is access to the affected areas, particularly in the south, which complicates firefighting efforts and maintains the visibility of the smoke. The smoke affects the north of the capital due to the northwest wind, but the situation does not present a significant potential for propagation.

The Marisma del Burro Natural Reserve, declared in 1984 and part of the Marismas del Odiel Natural Site, covers 597 hectares and holds multiple protection designations, including Natura 2000 and Biosphere Reserve.
