| | Natural Processes in the Bulfinch Triangle |
 | | The Mill Pond Plan, construction of the MBTA Green Line and Central Artery viaducts, and the construction of tall, tightly-packed buildings have all led to the diversion, pollution, and in some areas amplification, of natural air currents directed from the Charles River. |
 | | While no historical maps indicate the presence of gardens along Causeway Street before the viaduct, it is probable that “volunteer species,” such as those observed along sunlit streets like Canal Street, were commonly found growing from cracks and holes created in the streets and sidewalks by the ice wedging process mentioned earlier. |
 | | The microclimate under the Green Line MBTA, which does not support any native species is a strong indicator of changing environments. |
