Invasive species Management & research

Silv-Econ undertakes research about the detection, management and ecology of invasive species. Our team members have graduate degrees in forestry and soil science and are well qualified to design and implement research programs.

Examples of our work include:

  •  Collaborated with researchers at Agriculture and Agri-Foods Canada and University of Toronto on the development of a new biological control agent (Hypena opulenta) for dog-strangling vine
  • Conducted research on conservation biocontrol for EAB - including examining food resources for emerald ash borer parasitoids and potential strategies to enhance them. 
  • Conducted a stakeholder needs assessment for emerald ash borer (EAB) information and technology transfer. This resulted in the development of an educational website for stakeholders managing EAB and other invasive insects in Canada.

detection & management

Silv-Econ designs and implements surveys for detecting and quantifying invasive forest insect and plant species, and provides management recommendations for them.


Examples of our work include:

  • Hemlock woolly adelgid threat assessment and recommendations for monitoring and management in York Region
  • Spongy moth defoliation and egg mass surveys, and population forecasting
  • Prism trap surveys to detect the presence, advancement and intensity of emerald ash borer
  • Developed and implemented a protocol to map and monitor invasive plants in  York Region forests
  • Facilitate a hemlock woolly adelgid working group for forest practitioners

forest insects and invasive species

Silv-Econ has the expert knowledge and practical experience to detect, monitor and map native and non-native forest insect pests, and invasive plant species in forests. We design and conduct research programs on invasive species detection and management. This work often involves collaborative partnerships with universities, government agencies and municipalities.
