Ecuador
Ecuador is generally considered to have the highest biodiversity of plant and animal species in the world and about 4000 species of orchid have been found here, a thousand of them discovered in the past 12 years alone. Orchids are very common in Ecuador and some 4000 species are already classified although many more await official recognition. They are there as epiphytes on trees, as lithophytes on rocks or rooted in the soil in the more traditional terrestrial fashion.
