A New Biological Approach Is Helping Spain's Dying Oak Forests

Across parts of southwestern Spain, something quiet has been happening for years. No smoke. No dramatic headlines. No sudden disaster for people to point at. Just trees slowly losing strength. Leaves thin out. Branches dry. Entire oaks that stood for decades begin to decline until, eventually, they die. Locals call it "la seca." And for the people who depend on Spain's dehesa landscapes, it has become one of the biggest environmental worries in the region. Now, researchers in Extremadura may have found something that offers a bit of hope. Not a chemical treatment. A biological one. The Problem Is Bigger Than One Disease "La seca" is often described as a disease, but it is not really that simple. It behaves more like a decline process. Trees weaken over time. Their root systems struggle with water and nutrient uptake drops. Stress builds. One major suspect behind all this is Phytophthora cinnamomi, a soil pathogen that attacks roots and has been linked to oak de...
