Research:
I
have been involved with forest fire
history studies from 1995 onwards. I
have studied forest fire history of
eastern Finland by using
palaeoecological methods (charcoal
particle and pollen analyses). In
addition, I have studied history of
mire fires in Finland and in western
Siberia. At the present I am working in
research project "Changes in the fire
regime and forest dynamics in Finland
through past 4000 years" funded by
Finlands Akademi for period 2000-2002.
The project is a part of
multidisciplinary research
programmeFIBRE, (link:
http://fibre.utu.fi/). The present
research project involves with the
analyses of fire frequency and
associated vegetational changes in
forest ecosystems by means of a
stratigtaphical method based on
charcoal layers in marginal areas of
small mire basins.
Keywords:
