1. Introduction


2. Talks [15 mins for each]


(1). Indigenous land use shaped past wildfire regimes in the Basin-Plateau Region, USA

Vachel Kraklow (Charles University)

Short abstract: Climate is one of the dominant drivers of fire in the western U.S., however, Indigenous populations likely shaped local fire regimes for millennia. Here we reconstruct the past 1,200 years of fire, climate and changing human activity on the high-elevation Fish Lake Plateau, located on the Great Basin-Colorado Plateau boundary in the western U.S. We show people used fire to modify forests.


------ Questions & Biobreak ------ [5-8 mins]


(2). Fire history and its drivers based on peatland charcoal analysis in the Changbai Mountains, north-east China, during the last 13 000 years

Meng Meng ( Northeast normal university )

Short Abstract: The forest fire history of the Changbai Mountains for 13 000 years was investigated using charcoal records. The results demonstrate that fires were more frequent at the regional scale during intervals of a weak summer monsoon, caused by a cold and dry climate and the abundance of flammable trees. Since 3.0 cal kyr BP, increasing human activity dominated the occurrence of local fires.


------ Questions & Biobreak ------ [5-8 mins]


(3). Tracking tolerance and resistance traits of local grasses to fire and herbivory using a South African palaeoecological record

Abraham Dabengwa ( University of the Witwatersrand, South Africa )

Short abstract: Fire and herbivore consumers shape vegetation from ecological to evolutionary timescales. Tracking the plant life-history strategy response to consumers is key for understanding tolerance and resistance traits. In this talk, I show how flammability and palatability traits of grasses are valuable for tracking environmental change with the aid of a ~1250-year multiproxy record.


------ Questions & Biobreak------ [5-8 mins]
