OUR MISSION: ACER ACER supports communities, government agencies and corporations in taking action to reduce biodiversity loss and strengthen climate resilience by increasing and monitoring urban and riparian zone forest canopy.


This plot was established in 1997 as part of the Niagara Escarpment Biosphere Reserve Studies project (NEBRS), in which ACER partnered with Environment Canada, the Ecological Monitoring and Assessment Network (EMAN), and the Smithsonian Institution.

Each hectare is divided in 25 quadrats and data such as location of each tree (>4DHB), DBH and status is recorded (See 1997 Data).

In 2009, three 20m x 20m quadrats were randomly selected and re-measured. Every tree in the selected quadrat was measured and assessed in terms of general health, regeneration, presence of invasive species, and evidence of extreme weather events, such as blow downs (See 2009 Data).
