Mayor of Bogotá Enrique Peñalosa has proposed construction in the Reserve that could host 1.5 million people.[4]
The Thomas van der Hammen Natural Reserve is a rich natural area important for the biodiversity of the Bogotá savanna. Several endemic species have been registered, and two newly described species of butterflies were discovered in the Reserve.[5]
