environmentremains

Environmentremains is a term used in archaeology and environmental sciences to denote preserved evidence of past environments recovered from natural and cultural archives. These remnants, which include biological, chemical, and sedimentary traces, help researchers reconstruct vegetation, climate, hydrology, and ecosystem composition at specific times and places. The concept is distinct from artifacts and features, focusing on the environmental context in which human and nonhuman activities occurred.

Types of environmentremains include macroremains such as bones, shells, seeds, wood, and charcoal; microremains like pollen, spores, phytoliths, and diatoms; and geochemical signatures such as stable isotopes and trace elements. Together, these materials provide a multi-proxy view of past environments and can be complemented by dating techniques to place reconstructions within an chronological framework.

Formation and preservation of environmentremains depend on rapid burial, low oxygen conditions, mineralization, and stable sedimentary settings. Common sources include lake and peat sediments, floodplains, caves, archaeological middens, and stratified soils. Recovery methods often involve flotation to separate plant remains, careful stratigraphic excavation, and laboratory analyses such as palynology, microfossil identification, and isotopic measurements.

Applications of environmentremains span climate reconstruction, habitat change, resource availability, and human–environment interactions. They inform models of past biodiversity, aid in interpreting site function, and support conservation planning. Limitations include preservation bias, taxonomic difficulty, and interpretive uncertainty, all of which require careful taphonomic assessment and transparent reporting.
