The Metolius Intermediate Pine
site was established in 2001. It is located in a mixed-age ponderosa
pine stand initiated ca. 1915 (but with a mean age of 62 yrs), on Green
Ridge in the eastern Cascade mountains of Oregon about 30 km northwest
of the town of Sisters. The tower is 38 m tall and equipped with a full
complement of eddy covariance instrumentation and a vertical profile of
CO2 and meteorological data collection, powered
by solar panels and a wind generator. The site is also equipped with a
horizontal array of instrumentation collecting data on temperature,
soil respiration, sapflow, and tree growth, and contributes data to the
CO2 concentration project. The Metolius
Intermediate Pine site has been selected for a trial installation of
Neutron Soil Moisture Probe network, in collaboration with
the University of Arizona.
