Trees and Shrubs
Certain tree species have a tendency to grow together because they share preferences for soil conditions, light availability, exposure to harsh weather, and other biotic and abiotic factors. This has led to the formation of well developed forest groups. These forest groups have been well studied in Nova Scotia under the Forest Ecosystem Classification; several of these forest groups are prominent on Prince Edward Island as well.
Prior to disturbance and human settlement, much of Prince Edward Island was covered in Acadian forest. The Trees of the Acadian Forest is an interactive guide to the common tree species within this forest type.
Gaudet and Profitt (1958) developed the first guide to PEI's woody vegetation in Native Trees of Prince Edward Island and the More Common Woodland Shrubs. More recently, Native Trees and Shrubs is an excellent guide to Prince Edward Island's woody vegetation has been developed by the Macphail Woods Ecological Forestry Project, led by Gary Schneider. This group has also developed a detailed online guide to PEI's Trees and Shrubs.
