The hidden side of rarity: it’s not that rare being rare

Begoña García has spent many years passionately studying a curious plant, Borderea chouardii. It is a rare species with a biogeographical origin that dates back to the Tertiary and remains confined to a few limestone cliffs in the Central Pyrenees. Unknown until the middle of the 20th century, it is considered an endangered species. But... is it?

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.
