Why do we want to know history of the forest? better understanding of the present state advice on management decision making provides a broader perspective to our research WoS: “historical ecology“ 1973–2008 Historical ecology

“historical” resources -Not readily usable -Often qualitative For example: Urbaria Perambulations Estate conscriptions Account books Normative directives “ecological” resources -Readily usable -Mostly quantitative For example: Forestry documents Cadastres Estate maps ca AD History: “ecological” vs. “historical” resources The 1800-barrier older younger
Coppicing cycles – how often were forests cut Mikulov estate (S Moravia) Urbarium from 1384: “Das holcz, das do get niderhalb des wegs durich die Chlausen, das haist der Lelasch, und ist deselb zeit 2 jar alt gevesen; wann er zw 7 jarn chumpt, so schaczt mann für 36 lb. und 2 lb. ze leitchauff.” Forest description from 1692:

Forest in the Czech Republic currently 34% cover (and increasing)
Altitude: the most obvious large-scale factor < 400 m n.m m n.m. > 800 m n.m.
Lowlands mostly deforested since the Neolithic (7ka BP) long-term stability
Moravian cadastres The first record
Coppicing, our favorite topic
Lowland forests relatively best knowledge up to 400 (500) m of altitude European phenomenon warmer, usually drier climate long-term human inhabitation intensively managed stable in extent (ancient woodland) specific (and threatened) biodiversity
coppice high forest wood pasture Three basic management forms in the lowland forest most common in the past most common in the present information scarce
