Research interests
Dr. Tjaša Tolar is an archaeobotanist, she studies plant macroremains from archeological sites. Her main focus is on identifying charred remains of crops and gathert wild fruits/nuts, as well as charcoal. Rarely, but often archaeobotanical remains in Ljubljansko barje are preserved in a waterlogged state. They hold enormous research potential and enable the discovery of new knowledge about past vegetation, its changes over time, as well as the beginnings of agriculture. The pile-dwelling sites at Ljubljansko barje occupy a special place in archaeobotanical research in Slovenia. On the subject of fossilized, dog or human excrements (so-called coprolites) recently discovered at the Stare gmajne site.The interdisciplinary bilateral research project J7-2598, led by Tjaša Tolar, was completed in 2024. Archaeobotany can be perfectly combined with other sciences such as palynology, archaeozoology, paleoecology. Archaeobotanical discoveries often reveal the already forgotten knowledge of our ancestors who lived closely with nature thousands of years ago. Since 2023, Tjaša Tolar has been mentoring a PhD student Taja Skrt Kristan, who will try to identify changes in weed vegetation over time (i.e. ftom the Neolithic to the present day) and possible agricultural practices in the 4th Millenium BC.
