What will be left of the primary forest in Ecuador?

Ecuador is among the smallest countries of South America (250,000 square kilometers) but has the highest density of human population with the highest network of primary and secondary roads, which also explains why Ecuador has the highest slash-and-burn ratio per capita in America (about 250,000 hect...

Sumario: Ecuador is among the smallest countries of South America (250,000 square kilometers) but has the highest density of human population with the highest network of primary and secondary roads, which also explains why Ecuador has the highest slash-and-burn ratio per capita in America (about 250,000 hectares per year). Over 20% of the country’s surface has been declared as natural private and government reserves, where at least 2/3 of the area is totally inaccessible and has never been botanized. Thus, a large percentage of the approximate 1000 endemic orchid species described to date for Ecuador are probably not growing in these reserves. The remaining 80% of land is subdivided into 843,000 land ownerships, of which only 4% are parcels over 50 hectares. It can be concluded that no primary forests outside the reserves will survive the near future and respective endemic species will become extinct in nature. Ex-situ conservation is imperative.
