Site ID: CPEAK
Description: This is a weather station on the summit of Caribou Peak (2537' / 773m ASL) in the Caribou Poker Creeks Research Watershed. It consists of a 10-meter tower with various atmospheric sensors and ground temperature thermistors at eleven different depths.
Directions: The Caribou Poker Creeks Research Watershed is located off the Steese Highway 31 miles northeast of Fairbanks. The first two miles of Watershed Road (restricted access) can be driven with a car or truck to the confluence of Caribou and Poker creeks. From there, access to Caribou Peak via the Caribou Trail usually requires an ATV (or a snowmachine in the winter season). Turn right at the T-junction just above the confluence area and follow the trail straight up Caribou Peak (approximately 2 miles). On the summit of Caribou Peak there are two weather stations. The station to the west is a RAWS site that belongs to the Alaska Fire Service (BLM). The station to the east is the LTER CPEAK site.
Site History: The current met tower was installed in April 1998. This replaced an earlier station that was in service from 1993 through 1997. The station logged data during the FROSTFIRE experimental burn that took place in July 1999. In 2001 the station was connected to a radio telemetry network, allowing for remote data acquisition and near-real-time data displays on the Internet.
Location: The site is located on the broad summit area of Caribou Peak, right at the treeline elevation. There are no higher peaks nearby to limit the exposure of this site.
Site ID: CRREL-Met
Description: This is considered the primary climate station in the Caribou Poker Creeks Research Watershed. Located in the lower part of the watershed near the confluence of Caribou and Poker creeks, this station consists of a 12-meter tower with various atmospheric sensors, a separate tower with long and short wave radiometers, ground temperature sensors and soil moisture probes at various depths, plus an older site about 25 meters away with two air temperature sensors and additional ground temperature thermistors.
Directions: The Caribou Poker Creeks Research Watershed is located off the Steese Highway 31 miles northeast of Fairbanks. The first two miles of Watershed Road (restricted access) can be driven with a car or truck during the summer months. After driving across the bridge over Poker Creek, the CRREL tower will be seen about 100 meters ahead and to the left of the road. A short footpath leads from the road to the site. The radiometer tower is to the left (south) of the 12m tower and the CRREL AT sensors and datalogger are about 25m behind (west of) the tower.
Site History: The station's name comes from the agency that originally managed CPCRW and set up many of the research sites, the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL). The original site consisted of the CRREL AT air and ground temperature instruments, the radiometer tower, and a 3m tripod with air temperature, relative humidity, and wind sensors. In May 2000, the Water and Environmental Research Center (UAF) replaced the 3m tripod with the current 12m tower. New instruments for temperature, RH and wind were installed at this time. A tipping bucket rain gauge was added (plugged into the CRREL AT datalogger) in June 2003.
Location: Valley location, wind-sheltered, cold spot in winter. It is on a slight south-facing slope in open canopy black spruce, feather moss, and sphagnum moss; less than 100m from Caribou Creek.
Site ID: FP0A
Description: Newly vegetated sandbar
Directions: By boat, 1km down-river from BCEF road landing
Site History: In 1993 a large expanse (1km x 1km) of new sandbar was established as part of an island complex during a major shift in the channel of the Tanana River. In 1994 we established FP0A in the center of this area so that we could follow the succession from the first invasion by plants through to later stages of succession. We realized that there was a high likelihood that the area would experience frequent severe flooding and that there was some chance that the entire area would return to river channel without vegetation development.
Location: Tanana R., island, 1 km down river from termination of BCEF Road
Site ID: FP1A
Description: FP1A is located on a low early successional terrace (1.8 - 2 m above winter low river level) adjacent to the Tanana River. Vegetation establishment occurred in 1982 to 1983. Significant bank erosion has occurred since the establishment of the study area, resulting in loss of some study plots.
Directions: By boat, FP1A is 3 km upriver from the termination of the BCEF Road (at the Gravel Pit) on the north side of the river. It can also be reached by following a 2 km footpath beginning approximately 1 mile before the Gravel Pit on the BCEF Road.

Site ID: UP1A
Description: UP1A was established to follow the development of vegetation following the burning of a well developed 200 year old white spruce stand on a south facing slope. The vegetation has progressed from an herbaceous community following the fire to an open hardwood stand.
Directions: This site is located on the old 'Sawmill Road' about half way between the main BCEF road and the Argyle Highway. It can be reached, on foot or by snow machine or 4-wheeler, from either the main BCEF road or the Argyle Highway.
Site History: This stand originated as a 200 year old upland white spruce stand that was moderately to severely burned in the Rosie Creek fire in late May of 1983. Prior to the fire the stand and been the subject of considerable research on white spruce regeneration. At the time of the 1983 fire there were permanent vegetation plots that had last been measured in 1975. These 20 plots were relocated and used for the revegetation studies.
Location: BCEF, Sawmill Road, midslope
