DOI: The 2nd Section of Chapultepec Park is an ecological preservation site and provides ecosystemic services and anthropocentric benefits to the inhabitants of the Metropolitan Area of Mexico City. In recent years the tree cover has shown a reduction and decline. This condition must be reverted and reforestation programs can do in a short period of time. A species test of six native leguminous trees was assessed to determine the response to the conditions of the 2nd section.
