Trent University Researchers Awarded $253,700 to
Study Effects of Climate Change on Ganaraska Forest
FOR IMMEDIATE RELEASE
New Study to Determine Links Between
Forest Health and Bird, Insect Populations
Monday, May 11, 2009, Peterborough
A new study led by Trent University biology professor Dr.
Erica Nol to understand how climate change is affecting
birds and other fauna in the Ganaraska Forest will receive
$253,700 over three years from the Natural Sciences and
Engineering Research Council (NSERC).
“While scientists have a great deal of evidence showing
the dramatic effects of climate change in more northerly
reaches of the planet, there is less hard data available to
help us understand how southern environments are
impacted by climate fluctuations,” said Professor Nol, who
is collaborating with fellow Trent professors Dr. James Buttle of the Geography
Department and Dr. Shaun Watmough of the Environmental and Resource Studies
Department. “Thanks to NSERC’s strong support of this project, we can start to develop
models of forest health that can help us predict how changing environmental conditions
will affect birds and insects in this region.”
The project is being funded through the NSERC Strategic Project Grants. The program
seeks to increase research and training in areas that could strongly enhance Canada’s
economy, society or environment in the next 10 years “NSERC wants to make Canada a country of discoverers and innovators, for the benefit
of all Canadians,” said Dr. Suzanne Fortier, President of NSERC. “Professor Nol and her
partners are helping us realize that vision. I congratulate them on their success.”
Prof. Nol’s study will be conducted in the Ganaraska Forest, the largest single tract of
forest cover in the settled landscape of southern Ontario. As such, it is a major refuge for
forest trees and associated bird species, including some rapidly declining insectivores; in
fact, this region contains greater avian biodiversity than any other region in south-central
Ontario.
Since 1970, the Ganaraska Forest has experienced significantly less snow as a
proportion of total precipitation, a strong signal of the effects of climate warming. Prof. Nol and her team hypothesize that this decline in snow cover is impacting soil moisture,
a key regulating factor of forest biodiversity. Her study will investigate causes of
variation in soil moisture among different forest stands and at different slope positions,
and how that variation relates to nutrient availability for vegetation, and insect and avian
biodiversity and productivity.
Through this research she will also test the strength of connecting links between
precipitation inputs, soil moisture, soil nutrients, vegetation, insect prey and birds. If the
connecting links are strong then changes in the pattern of winter precipitation due to
climate change will have cascading effects to the bird communities. If these links are
weak, this will reflect greater resiliency in the ecosystem to changes in precipitation
patterns.
“Our ultimate objective is to construct a predictive model that will allow us to identify the
most productive forest types and slope positions for long-term persistence of the avian
community and forest sustainability,” said Prof. Nol, whose research team will include
two Trent graduate students and nine technicians/research assistants. “The model will
use inputs from the field work and a range of values within those predicted for variation
in the ratio of snow to total precipitation.”
Prof. Nol noted this work will be useful for complying with the Crown Forest
Sustainability Act of Ontario, and is supported in part by the Ganaraska Forest
Conservation Authority and the Ontario Ministry of Natural Resources.
