The wax palm is on the way to extinction, and for this reason, the teacher Maria José Sanín Pérez and the botanist Rodrigo Bernal did an investigation on the sex change of a hundred palms located in Tochecito, Valle del Cauca, this, to help their conservation and reproduction.

The published research called "Stalking the wax palm in danger of extinction", recounts the journey that Dr. Bernal and the teacher Sanín made in Tochecito and how they analyzed the palms that years ago were cornered and poorly preserved by the presence of the FARC in the Cauca Valley.

This article reiterates the current difficulty of preserving wax palms, not only because it is an economical diet for livestock, but also because of the arrival of foreign companies that want to stay in the sector to do mining.

That year, Dr. Bernal and Dr. Sanín proposed a government-backed palm sanctuary that would protect the entire 32 square miles of the river basin. But after 18 months of meetings in Bogotá, meetings with owners, meetings with the Ministry of Environment and Sustainable Development, Dr. Bernal said, most of Tochecito's landowners walked away from the table, feeling that their activities would be too restricted. ”Relates the New York Times article.

The Biology teacher and Dr. Rodrigo Bernal are currently working on a project to update the guide for Colombian palms and are adding 28 species that most have been identified in former conflict regions.
