Përmbledhja	Archaeobotanical flotation is the standard recovery technique for charred plant macroremains, separating buoyant carbonized seeds, nutshell, and wood charcoal from archaeological sediment by agitating the soil in water. Because carbonized tissue is light and water-repellent, it rises and overflows into a fine mesh as a 'light fraction,' while denser bone, lithics, and uncharred residue settle as a 'heavy fraction.' The remains are then dried, sorted under low-power magnification, and identified against modern reference collections to reconstruct past diet, agriculture, fuel use, and environment. Machine-assisted water flotation was popularized by Stuart Struever in the late 1960s and systematized for routine paleoethnobotanical practice by Deborah Pearsall, whose handbook codified sampling, processing, and quantification procedures now used worldwide.	Site catchment analysis models a settlement's economy by delimiting the territory that its inhabitants could realistically exploit and inventorying the resources within it. Introduced by Claudio Vita-Finzi and Eric Higgs in their 1970 study of the Mount Carmel area, the method rests on the premise that the cost of moving to and from a site falls off sharply with distance, so most subsistence activity occurs within a limited radius. By drawing a catchment — classically the area within one or two hours' walk — and measuring how much of it is arable land, grazing, water, lithic sources, or wild biota, the analyst characterizes whether a site is oriented toward farming, herding, hunting, or gathering. Modern practice replaces simple circles with terrain-sensitive least-cost territories computed in a Geographical Information System, as set out by Conolly and Lake.
