In recent times, wooded area fires have turn into extra in style, extra common and extra serious in lots of portions of the sector. Summers are warmer, droughts are longer, and wildfires that have been outstanding many years in the past are actually common.
In line with the Ecu Wooded area Fireplace Knowledge Device, greater than 540,000 hectares burned within the Iberian Peninsula in August 2025, the best possible quantity on document.
Gas wealthy landscapes
When requested whether or not local weather trade is in the back of them, the solution isn’t easy. Surely, local weather trade lengthens the dangerous seasons and creates extra favorable stipulations for the prevalence of fires, however it’s not the one motive. Wooded area fires additionally rely at the ignition supply, the terrain and the crops that feeds them.
To know the present fires, we additionally want to take a look at the panorama now we have constructed.
For the reason that nineteenth century, quite a lot of huge plantation methods aimed toward bushes manufacturing, soil coverage or financial construction have unfold throughout Europe. In Spain, greater than 5 million hectares were planted, most commonly with pine species, a legacy that has deeply marked the present panorama.
Through the years, rural abandonment has larger the volume and continuity of biomass, growing fuel-rich landscapes that are actually extremely susceptible to fireplace. However how do various kinds of gas have an effect on fireplace severity and fireplace restoration? Can control scale back the affect of fireside in plantation-dominated landscapes?
Classes discovered from the fires in Spain
Our staff studied 3 huge fires in Spain (Sierra Bermeja, L. a. Culebra and Las Hurdes, which happened between 2021 and 2023) and we discovered that pine plantations burned extra significantly than oak forests, combined forests or scrub. Additionally, those ultimate 3 sorts of crops confirmed transparent indicators of restoration after 12 months, whilst the plantations remained almost abandoned.
A 12 months after the hearth, the panorama of the forested spaces didn’t resemble the unique ecosystem, however neither did it resemble a functioning plantation. We additionally spotted that plantations can threaten their neighbors. In 3 fires, the depth of the hearth within the surrounding crops used to be larger the nearer they have been to the discussed plantations.
On the other hand, no longer all plantations burned similarly. We found out a threshold of about 440 pine timber consistent with hectare: above that density, the depth of fires skyrockets. However, in the ones plantations the place the density of timber and trees used to be controlled, the results of the hearth have been a lot much less critical.
Those observations are just right information, as a result of they imply that managing those plantations could make a distinction. Practices akin to thinning, pruning, or selective logging scale back gas load and continuity, and feature been efficient in decreasing fireplace affects in the ones spaces. Shifting from an deserted plantation to a controlled plantation could make the variation between a hearth that may be put out or a hearth this is extraordinarily tough to control.
Advertise a extra numerous and not more flammable panorama
Prior to now, pine plantations performed a key function within the Ecu economic system and formed a lot of the panorama we see nowadays. Some reforestation helped stem land loss after many years of overexploitation, and wages from forestry allowed many households to reside with dignity within the post-war economic system.
On the other hand, in a context the place climatic stipulations are turning into extra serious, those plantations are in danger of changing into hotspots for massive fires.

The result of our analysis display that no longer all crops burns in the similar means, however that the kind, density and aggregate of gas resolve the results of fireside at the ecosystem and its talent to get well. This discovering is vital: it signifies that huge investments in wooded area control are not not obligatory.
We want to prevent specializing in placing out fires once they happen and get started specializing in decreasing the vulnerability of the territory sooner than the hearth begins.
Selling a extra numerous and not more flammable panorama, in addition to keeping up plantations underneath energetic control, is a practical and efficient technique. The measures integrated no longer handiest supply non permanent advantages, but additionally toughen regional fireplace prevention and adaptation plans. Additionally, they supplement, however don’t change, international methods aimed toward mitigating local weather trade.
Despite the fact that its implementation includes prime prices and logistical demanding situations, it additionally provides alternatives to advertise a extra sustainable forestry trade, mitigate the results of rural abandonment and advertise landscapes the place plantations are a part of the stability between financial productiveness and ecosystem preservation.
In an increasingly more sizzling and fire-prone global, planting timber as a local weather trade mitigation technique carries important dangers. On the other hand, not like climate or topography, gas is inside of our keep an eye on.
Rethinking what species, the place and the way we plant them, and above all, what occurs to them afterwards, is an crucial situation for construction extra fire-resistant landscapes and, in the long run, for studying to reside with it.
