Plain Language Summary

The Canadian Forest Service is currently developing new techniques to improve our understanding of ecosystem integrity. The presence or absence of “indicator” species in soil and water can provide a way of measuring changes in biodiversity in response to various forest management practices. The assessment of ecosystem integrity is a critical activity within the forest management community. It contributes to the sustainability of Canadian forest management practices, helps maintain domestic and international market access for wood products and supports our social license to harvest wood.

The development of cost-effective, ecologically relevant, sensitive and standardized indicators is an essential component of biomonitoring. The Canadian Forest Service is developing metabarcoding techniques to address this challenge. Metabarcoding is a DNA-based method of identifying multiple species from a sample of environmental DNA and provides a signature of the organisms that reside or pass through a particular environment. It is particularly effective because DNA can be extracted from a water or soil sample even when there are no intact organisms in the sample. Data from the metabarcoding of soil for example, can provide important information on changes in the soil biodiversity in response to alternative forest management practices.
