Humans known for their notorious deeds just to make their selfish ends meet, has been mercilessly and indiscriminately plundering the planet’s resources. Here is another astounding evidence of human perditions – that they have widely burned the Costa Rica’s forests.
And for a rainforest to overcome such devastation and re-grow to another pristine green lash, it takes 170 years! And, a new study has discovered evidence of charcoal in the region’s tropical forests.
This along with documentation of soil charcoal’s presence at every surveyed forest site from sea level to the Costa Rican highlands clearly suggests that the otherwise ‘virgin’ tropical forests are less than 200 years old.
This is uncovered by radiocarbon dating of montane forest soils in Costa Rica. Thus, the naturally-caused forest fires along with human presence imply the Costa Rica’s tropical forests’ multiple recovery from extensive burns.
The find of maize pollen in these studies sites shows what the humans have turned the tropical forests to!
The practice of maize cultivation over the past 7,000 years thus, reveals the extent and the time for which human populations in Central America may have been exploiting and modifying the tropical forests’ original character.
So, can we conclude that no rain forest is more than 200 years old and none could retain their original character, especially with changing climes?
