Vancouver is part of the coastal western hemlock biogeoclimatic zone.
Therefore, Stanley Park is considered very biodiverse, with many different tree, flower, and grass species.
 There are many threats to these plants such as invasive species.
Conservation of these species is a priority for the Society as well as the management of existing flora; for instance, the Hollow Tree is a landmark of Stanley Park that needs constant maintenance.
