Preliminary Results
Study Design
17 permanent vegetation plots along 5 transects throughout watershed
2 DOC collection devices (lysimeters) per plot placed at 70—90cm depth
Soil cores collected to determine root growth dynamics
Collection frequency: once per month in early winter** and once per
week late winter through spring
Analyze water samples for Total Carbon and Ammonium
We predict:
1.
Relatively small carbon loss through soil since carbon leaving the
system via stream flow is also small.
2.
Early season carbon flux spike as water soluble carbon built up
throughout the summer in the top soil layer is washed into soil.
3.
Spatial variability of carbon concentrations to be dependent on plant
community variability
** During early winter the watershed was inaccessible due to snow.
As a result lower than
desired sampling frequency occurred.
