Elevation of Center Point in Meters: 300m
Frequency of Collection: Alluvial
dynamics: imagery May, June, July, August, September
Floodplain succession:
annual cloud-free imagery
Canopy nitrogen: AVIRIS
type imagery once during growing season
Upland succession: imagery
every five years
Post-fire establishment:
imagery summer after the fire
When (time of day or season or
whatever) should data be collected? Anytime
when cloud-free imagery is available during the growing season (May-September)
Resolution needed from data
(or scale needed): 1-meter for
estimating canopy N, 20-50m for other applications.
What is the impact of not
collecting the data when requested? Some
applications (mapping canopy N
Or documenting alluvial
dynamics impossible without remotely sensed data.
Describe the things or phenomena to be monitored and the purpose of the monitoring. Include information about the duration needed for monitoring to be effective.

What ecosystems are present at the site?
Taiga boreal forest: black spruce, white spruce, quaking
aspen/paper birch
Floodplain succession: willow, alder, balsam poplar, white and black
spruce
Upland succession following
wildfire: Calamagrostis/shrubs/aspen-birch/spruce
Fluvial and lacustrine
boreal wetlands
Are there management issues associated with the site?
Recreational use, timber
and firewood harvesting in nearby areas.
Is the site designated for special management or use (e.g. long term studies, specially reserved regions)?
Long term plant, soil,
climate, herbivore monitoring
Have previous monitoring activities been done at this site? If so, are data available in digital form?
Monitoring for the past 12+
years. Data available at
www.lter.uaf.edu
Describe any special characteristics of the site or the things or phenomena that are to be monitored (information that might help determine how it might be useful to monitor the things or phenomena at the site).
The primary research emphasis
of the site is changes associated with disturbance in the upland and
Floodplain landscapes. Primary disturbance agents include wildfire,
alluvial deposition and erosion,
Insect infestations, snow
and ice damage, thermokarsting, permafrost changes.
