Title of Project

An investigation of non-climatic factors influencing range expansion of 4 northern temperate tree species in Newfoundland

Project Description

My project is aimed at bettering our understanding of the forces at
work under climate change-driven forest change at the boreal forest -
deciduous forest ecotone. Anthropogenic global warming is producing
favourable climatic conditions for southern tree species north of
their current range limits. However, climate is only one factor
influencing biome shifts, with other drivers operating at regional
(e.g. soil characteristics, topography) and local (e.g. pest
outbreaks, herbivory) scales. The complex suite of non-climatic agents
makes the question of whether or not the deciduous forest will advance
northward into the southern boreal forest more difficult to answer. My
experimental field study will manipulate a combination of non-climatic
factors to observe their influence on seed germination and early
seedling survival of four temperate tree species, Acer saccharum,
Betula alleghaniensis, Fraxinus nigra and Thuja occidentalis, beyond
their northern distributional range. It is my ambition that the
findings from this project will contribute to our understanding of how
this and other forest – forest ecotones will change with a warming
climate.
