In northeast Colombia, police guard warehouses stacked high with confiscated timber with a noble new destiny: transformation into homes for bees beleaguered by pesticides and climate change.

The illegally harvested wood is used in northern Colombia’s Santander department for its “Timber Returns Home” initiative, which has been building hives since 2021 to house the little pollinators so critical to human survival.

So far, the project has seen about 200 cubic meters (7,060 cubic feet) of wood transformed into 1,000 bee hives, with another 10,000 planned for the next phase, according to the Santander environmental authority.

Previously, confiscated timber was turned into sawdust and donated to municipalities for projects, or sometimes just left to rot.

Now it is being repurposed to help address the “extremely serious problem” of possible bee extinction, said biologist German Perilla, director of the Honey Bee Impact Foundation.

About three-quarters of crops producing fruits or seeds for human consumption depend on pollination. Still, the United Nations has warned that 40 percent of invertebrate pollinators – particularly bees and butterflies – risk global extinction.

“The main threat is that we will run out of trees and there will be no flowers because, without flowers, there are no bees; without bees, there are no humans, and we will run out of food,” said beekeeper Maria Acevedo, one of the beneficiaries of the project.

In 2023 alone, she said, she lost more than half of her hives. She blames pesticides used in the nearby production of crops such as coffee.
