Netters: I am looking for information regarding emulating natural disturbance patterns by timber harvesting. Natural disturbance could include fire, windthrow (blowdown), and insects/diseases. I am especially interested in the disturbance pattern by frequency and size class in the Great Lakes-St. Lawrence forest in Canada and in Boreal forests anywhere. I am currently developing guidelines for harvest layout and configuration for the Ontario Ministry of Natral Resources, Canada. If you could provide me with background literature and on-the-ground implementation experience, it would be greatly appreciated. --- Dr. Mark Johnston Centre for Northern Forest Ecosystem Research Lakehead University, 955 Oliver Road Thunder Bay, Ontario, Canada P7B 5E1 tel (807) 343-4012 fax (807) 343-4001 internet: mjohnsto@sky.lakeheadu.ca
