If you search, Honduras does have comparable trees, but Puerto Rico keeps getting hit by hurricanes, and that has quite an impact on tall trees even in the ravines. Regarding deforestation, actually Costa Rica was deforested faster than any other Latin American Country until the mid 1990's read Breakfast of Biodiversity: the political ecology of rain forest destruction by John H. Vandermeer, Ivette Perfecto. Anyway, in more recent years Costa Ricans have done quite well preserving what they have left which is quite substantial, though there are continuing battles to prevent illegal logging in some of the parks and mining of riverbeds for road building materials. What you see in my images is not old growth forests but trees that were spared because it was more trouble to pull them up from the steep ravines than the wood of the Wild Cashew is worth. Still, the people realize how important the environment is to their tourist based economy, and this helps a lot.
