Résumé	Phytolith analysis is a laboratory technique used to identify and quantify microscopic silica bodies deposited in plant cells, recovered from soils, sediments, or archaeological contexts. Because phytoliths preserve long after organic material has decayed, the method is central to reconstructing past vegetation, crop histories, land use, and soil development across agronomy, paleoecology, and archaeobotany.	Dendrochronology is the science of dating and interpreting wood and climate from tree rings. Each annual ring records the tree's growth response to weather during that year: wide rings indicate favorable conditions (adequate water, warmth, light); narrow rings indicate stress (drought, cold, shade). By crossmatching ring-width patterns across trees and backward in time using dead wood, researchers construct chronologies extending centuries to millennia, providing archives of regional precipitation, temperature, and hydroclimate independent of instrumental records.
