“The role genetics/genomics research can play in forest management is huge but, unfortunately, remains under-utilized,” said Dr. Om Rajora, Professor of Forest Genetics and Genomics at the University of New Brunswick, Canada.

DNA fingerprints of 10 individuals each of white spruce (WS), black spruce (BS) and red spruce (RS) at a genic microsatellite showing genetic diversity; C. Sampling of old-growth and post-harvest second-growth black spruce to examine the genetic effects of forest harvesting and renewal practices in Manitoba (Rajora and Pluhar 2003, Theor. Appl. Genet. 106: 1203-1212); D. Testing of three-generation outbred pedigree of black spruce under ambient and elevated CO2 conditions for QTL mapping of traits related to acclimation and adaptation to climate change. All pictures were taken by Dr. Om Rajora or his associates.

“Genetics/genomics research can greatly assist the management of natural and planted forests by conserving healthy, productive, well-adapted and genetically diverse natural forest and developing high yielding tree varieties with desired traits for deployment in plantations,” he said.

Dr. Rajora is the organizer and coordinator of a session entitled Genetics and Genomics for Conservation, Climate Adaptation and Sustainable Management of Forests to be presented at the IUFRO 125th Anniversary Congress in Freiburg, Germany in September. Read more…

Forest ecosystem restoration is a critical component in tackling climate change, combatting biodiversity loss and desertification, and for providing products and services that support livelihoods at a local level.

For those reasons, restoring and rehabilitating forests and degraded lands will be one of the major environmental challenges of this century.

But, as a recent thematic study coordinated by Bioversity International, a IUFRO Member Organization, for the Food and Agriculture Organization of the United Nations – Genetic Considerations in Ecosystem Restoration Using Native Tree Species – notes, there is more to forest restoration than simply planting trees.
