Summer 2009 Harvest
The summer of 2009 will be an exciting time in Rhinelander. We will initiate
our planned harvest of the FACE experiment following a protocol developed
collaboratively between Michigan Tech, the USFS (Rhinelander), the University
of Michigan, and the University of Nevada, Reno. The above- and belowground
portions of the experiment will be harvested by block once the entire
canopy has developed (all the determinate shoots have elongated). First,
the trees will be cut at ground line and taken back to the field lab for
analysis. Then, an excavator and commercial soil sieve will be used to
recover most of the roots. This exercise will be a real adventure and
the results should eventually be very interesting! Details of the harvest
protocols and a schematic are available on our website (Details
If anyone has a need to collect data during the harvest or would like
samples from the harvest, please complete the registration form for research
requests on our web site http://aspenface.mtu.edu/reg.htm.
These requests will be handled just like all the previous requests to
conduct research on the site. They will be reviewed by the Executive Committee
and approved unless there is some conflict with the official harvest protocol.
Having a brief description of the sample types needed and their purpose
as soon as possible will facilitate a timely, coordinated harvest. A sample
archive will be created, but its purpose is to fulfill requests for future
needs that were unknown at the time of the harvest. Meeting current needs
during the harvest will help ensure that the archive lasts well into the
future. The Executive Committee will begin reviewing requests during a
February 18, 2009 meeting. Early requests will be much easier to accommodate.
Sample that will be generated by the harvest include:
- leaves by annual height growth increment (HGI)
- stem cross sections every 1 m and at midpoints of HGI
- branches by order, composited across HGIs
- buds from all 1st order branches within each HGI
- coarse (> 1 mm) and fine (< 1 mm) roots by 10 cm depth increment,
to 1 m depth.
- root free mineral soil by 10 cm depth increment, to 1 m depth
Northern Forest Ecosystem Experiment (NFEE) is funded by the US
Forest Service. The Aspen FACE Experiment is funded principally
by the U.S. Department of Energy's Office of Biological and Environmental
Research. Additional support is from the USFS Global Change Program,
Michigan Technological University, the Canadian Forest Service and
the USFS Northern Research Station.
