During several days of January, the IDForest team is carrying out the replication tasks. So far, work has been carried out in farms located in the province of Cáceres (Spain). New plantations of holm oak and cork have been mycorrhized with Pisolithus arhizus oak (Finca Matilla de Abajo and Atoquedo) and adult trees have been protected with bioremediation techniques (isolation of local Trichodermas) in the farms of Navezuelas, Matilla de Abajo and Atoquedo.
