Objective(s): Main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon.

Project Description: The main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. Additional objective is to conduct a regional study of stand development and its relationship to environmental factors in a several-square-kilometer study area of mostly black spruce.
Five methods will be used. 1) Soil and air temperature will be measured with sensors and data loggers. 2) Aboveground forest litter will be collected with the litter traps. 3) Annual growth of fine roots will be estimated by setting the fine root ingrowth/litter trap cores made of cylindrical thin soil columns in the study plots. 4) About ten study plots of boreal forests are used in a several-square-kilometer area, and marked permanently for a study of silvichronology. Tree sizes and numbers of these stands will be measured as the base-line data. 5) A few trees will be cut in areas adjacent to some of the plots (about 10 trees in total) for the study of silvichronolgy to examine tree rings and history of stand development.

The researchers will give a seminar on their research project to the local community. They will also organize a field trip to the study sites with Aurora Research Institute for explaining research activities to interested persons.

Results of the study will be published as research papers in scientific journals. The research team will also explain the results in presentations in plain language to the local community.

The fieldwork for this study will be conducted from September 4, 2013 to October 31, 2013.
