In the woods at Barra del Colorado is extreme northeast Costa Rica, officials have a bit of a mystery.
Someone cut most of the growth on four hectares of land in a sector known as Caño Pereira. The region is part of Pococí, Limón.
The land is believed to be public property, but there are major restrictions on cutting trees and shrubs.
The Fuerza Pública said that a frog that is in danger of extinction lives in the area. The Ministerio de Ambiente y Energía is involved both because of the frog and because of the clear cut woodlands.
Police found a shack and a tent that were unoccupied on the site along with some shotgun shells.
Similar activities elsewhere, such as in the Talamancas, would suggest the beginnings of a marijuana farm. But cultivating the weed might not be successful in the this region around the Río San Juan.
