For years, companies took advantage of Costa Rica’s forest in Guanacaste. The area was left almost barren, with only a select species of plants and trees growing, and the soil’s nutrients sapped. But the Conservation Area of Guanacaste had a plan up its sleeve to restore the forest to its natural diversity – orange peels!
Ecologists representing the conservation park, Daniel Janzen and Winnie Hallwachs, established a deal with a nearby company that produced tons of waste in orange peels and pulp with nowhere to put them. 12,000 metric tons of orange peels were driven into the park and dumped – and then left completely unattended for years.
16 years later, Timothy Treuer, a graduate student went on a trip to visit the site and document any changes that had taken place since the great orange-peel-dump. When he found the exact location, he was astounded by the difference: it was “like night and day”.
Treuer reported, “It was just hard to believe that the only difference between the two areas was a bunch of orange peels. They look like completely different ecosystems.” (1) He and a team of Princeton University researchers then led a 3-year study documenting the changes that happened in the park’s ecosystem.
The area was filled with 24 times the number of species compared to the forest areas that hadn’t been treated with orange peel compost. The researchers found higher biodiversity, richer soil, and a well-developed canopy (i.e. treetop coverage).
Ultimately, this success story bodes well for other forests that have been sapped of their resources – with the pollution epidemic and climate change posing serious threat to nature’s resources, being able to undo damage in a short period of time is incredibly significant.
