Problem

Chapultepec Forest had an over-density of trees, which caused several issues such as competition between species, soil compaction due to lack of light, and poor water infiltration into the subsoil. 

Actions Taken:

• A forest sanitation program was established throughout the First Section of the Forest.
• Soil decompaction was carried out and reinforced with mulch production. mulch.
• Gardening work was performed.
• Spaces were created for the growth of shrubs and herbaceous plants necessary for ecosystem sustainability and visitor recreation. 

What is Forest Sanitation?

It is a set of actions aimed at improving the health of trees, shrubs, and herbaceous plants within Chapultepec Forest. Pruning, thinning, removal, and replacement tasks are carried out by experts under the supervision of the National Institute of Forestry, Agriculture, and Livestock Research (INIFAP) and initiated by the Chapultepec Forest Trust.

• Pruning: Improves tree structure, balance, health, and appearance by selectively removing dead, infested, diseased, rotten, or poorly positioned branches.
• Thinning: Involves removing sprouts on trunks or relocating closely spaced trees to provide more sunlight and reduce competition for space and nutrients.
• Removal and Replacement: Trees are susceptible to pests, diseases, or vandalism. In urban areas, dead trees pose a risk to people because their roots soften and they may fall. Therefore, removal and replacement of dead or unhealthy trees is performed in accordance with standard NADF-001-RNAT-2006.
• Chipping and Spreading: Removed trees are chipped to produce mulch, an organic material made from leaves, branches, and trunks, which is used to nourish the soil.
