Interaction of fire, climate, and human history of northern Mongolia

Presented by Byambagerel SURAN on 16 May 2013 from 11:00 to 11:20
Type: Oral Presentation
Session: Fire Ecology II
Track: Fire ecology

Content

In Mongolia, mean annual temperature has increased by 2OC and forest and steppe fires have increased in temporal and spatial scales in recent decades. We developed a network of fire-scar chronologies across forests in northern Mongolia to place this recent fire history and associated fire climatology into their longer term historical context, and to assess relationships between historical fires and climate and human influences. Trees sampled include both Scots pine (Pinus sylvestris) and Siberian larch (Larix siberica). Cross sections from 10-20 fire-scarred trees were collected from each site using a targeted sampling approach. All sites had fire histories that ranged from 250-450 years, and fire scars were frequent in all stands. Regional fire dates have been identified from local fires, and used to disentangle longer term patterns of top-down climate forcing of fires from bottom-up human factors across this region of the world.
