Around 30,000 trees and shrubs were planted between 2016 and 2019 in the Mediterranean basin and the Canary Islands, with a survival rate achieved that varied between 20 and 80%, depending on the species involved. The economic analysis shows that the Cocoon system can be up to four times more profitable than the normal reforestation method.
Through research conducted on young Scots pine trees and Diprion pini, a sawfly common to conifer forests in the Northern Hemisphere, scientists have shown, for the first time, how trees take steps to protect themselves against insect infestation even before eggs are laid on them.
According to a study led by the Spanish National Research Council (CSIC), the way trees have responded to drought in the past could be a key indicator of their risk of mortality. The study examined growth rings to compare that response in dead and surviving trees.
Yew is considered a species of interest from the point of view of conservation for its small and isolated populations. An international team led by CREAF has studied the adaptive variation of their populations, a crucial knowledge to develop correct conservation measures.
A study involving three CREAF researchers has found that plants with low nitrogen and phosphorus concentrations in their leaves do not reproduce every year to enable them to reproduce on a huge scale in years in which conditions are right. Oaks, holm oaks and beeches are examples of trees that behave in such a way.
