It is now well known that trees sequester and store CO2 by fixing carbon in permanent forms of biomass. The amount of gas exchange between a tree and the atmosphere changes depending on the age and health status of the tree itself. However, the overall net balance of a patch of vegetation in equilibrium with the surrounding environment can be considered stable in time. This balance, however, is altered by man through factors such as an increase in fossil fuel emissions and the relationship between crops and the utilisation of biomass. In this regard, the peri-urban forests, city parks and gardens, serving as CO2 sinks, play a vital role in combating the rising levels of atmospheric carbon dioxide.
