Article Synopsis
  • - Urbanization, particularly air pollution from ozone (O), has negatively impacted urban forests, especially fir forests near Mexico City since the 1970s, leading to the decline of these ecosystems and raising concerns about their survival.
  • - A study compared young symptomatic and asymptomatic fir trees exposed to varying levels of ozone, finding that asymptomatic trees had thicker epidermis and higher terpene concentrations, suggesting healthier responses to the pollution.
  • - The research highlights significant genetic variation and phenotypic responses among trees, providing insights into ozone tolerance and potential strategies for forest restoration in urban areas.

Peri-urban forest monitoring requires indicators of vegetation damage. An example is the sacred fir (Abies religiosa) forests surrounding Mexico City, which have been heavily exposed to tropospheric ozone, a harmful pollutant, for over 4 decades. We developed a participatory monitoring system with which local community members and scientists generated data on ozone tree damage.
