The Ontario Tree Project began in 1994, upon the signing of an agreement between The Arboretum, University of Guelph and the Genetic Heritage Program, Ontario Forest Research Institute. A vast network of volunteers, numbering over one thousand participants, was utilized to survey the province's trees over a four-year data collection period. The data collection phase of the project is now complete.
A computer database and Geographical Information System (GIS) has been developed to map the collected information; we are currently in the process of incorporating the data into a publication, the "Atlas of the Trees of Ontario." The goal of the project is to produce detailed range maps, illustrating the distribution and relative abundance of Ontario's trees. More detailed analysis for certain species may also be included. Here is a sample of the type of map that we've been able to produce from the data collected for Bitternut Hickory (Carya cordiformis)*.
