Coulee Experimental Forest larch needle-cast environmental data logs, 1981-1982 and 1984-1987

Meteorological and phenological data were collected for European larch on the Coulee Experimental Forest in Wisconsin from 1981-1982 and 1984-1987 (data are missing for 1983). Data were collected generally biweekly from April to November. Variables recorded include: rainfall, terminal shoot growth, needle growth, high and low temperature, and phenological notes about the trees.
These data were collected as part of an effort to study the development, life-cycle, and spread of larch needle-cast (Mycophaerella laricina) in the upper Midwest (Wisconsin and Iowa). As far as known, these data were not part of any specific study or research but were part of a larger framework of learning about this disease.
There are some data included in the supplemental progress reports that refer to a second site in the Yellow River State Forest located in Iowa. Additionally there are non-environmental data within the progress reports regarding data such as seed sources, disease ratings and tree heights that were not included in the data archived in this publication. This is due to the lack of supporting materials available when archiving these data.
