Resumen

Forests help reduce global warming by capturing carbon dioxide. Their conservation is vital, especially for those at risk of disappearing, such as montane (high Andean) forests. In the Sierra of Lima, Huarochirí province, the Bosque de Zárate Reserved Zone protects a western montane forest rich in biodiversity and endemic species, ranging from 2,700 to 3,200 meters above sea level. However, limited financial resources from both local authorities and the San Bartolomé farming community threaten its conservation. This study addressed the issue by: (1) estimating the carbon stored in the aboveground biomass of calo and chachacomo trees, (2) identifying economic activities with offsettable emissions using the MINAM “Carbon Footprint Peru” platform, and (3) proposing an alternative funding method for conservation. A total of 27 plots (250 m2 each) were evaluated between 3034 and 3200 meters. Tree height and diameter were measured to estimate biomass through allometric equations, then converted into carbon and its CO2 equivalent. The total aboveground carbon stock was estimated at 329.23 tons of carbon, averaging 6.67 ton C/ha. Chachacomo contributed 5.04 ton C/ha, showing more potential as a carbon sink than calo (3.49 ton C/ha). This carbon stock equals 1208.33 tons of CO2 equivalent, enough to offset emissions from companies operating in offices, accommodation activities, and food services. These businesses represent a promising market niche for funding conservation through voluntary donations, crowdfunding platforms, or conservation trust funds.
