Bartlett Experimental Forest NEON - United States of America
Bartlett Experimental Forest NEON
United States of America
The Bartlett Experimental Forest is relocateable site in Domain 01 Northeast and the site is part of NEON's sampling design. The site is located in New Hampshire. BART extends from the village of Bartlett in the Saco River valley at 680 ft to about 3,000 ft at its upper reaches. Aspects across the forest are primarily north and east. This particular site was chosen because it represented conditions (soils, elevation, climate, tree species composition) typical of many forested areas throughout New England and northern New York. An actively managed forest: manged protions (30% reflect a range of forest patch sizes and structural distrubutions. Sampling area is 15.66 km^2. . Airborne remote sensing surveys of this field site collect collect lidar, spectrometer and high-resolution RGB camera data. The flux/meterological tower at this site is 116’ with 6 measurement levels. The tower top extends above the vegetation canopy to allow sensors mounted at the top and along the tower to capture the full profile of atmospheric conditions from the top of the vegetation canopy to the ground. The tower collects physical and chemical properties of atmosphere-related processes, such as humidity, wind, and net ecosystem gas exchange. Precipitation data are collected by a tipping bucket at the top of the tower and a series of throughfalls located in the soil array. This site has five soil plots placed in an array within the airshed of the flux tower. Field ecologists collect the following types of observational data at this site: Terrestrial organisms (birds, ground beetles, mosquitoes, plants, small mammals, soil microbes, ticks), Biogeochemical data, and and soil data. Total data products collected at this site is 116.
General Characteristics, Purpose, History
Relocateable sites such as BART gather data for research projects under a few major themes including land use change, invasive species, and nitrogen deposition. The Observatory will move relocatable sites periodically to address the Grand Challenges in Environmental Science and other environmental gradients by surveying contrasting areas of environmental change. Site location criteria include: Location in an area subject to ecological phenomena, specifically relevant to the Grand Challenges; Proximity to core sites for logistical convenience; and comparability to nearby core sites, which provide wildland baseline information.The Observatory's comprehensive design supports greater understanding of ecological change and enables forecasting of future ecological conditions. Exogenous factors likely to affect forest growth and composition into the future include climate change, increasing regional rates of atmospheric deposition (S, N and Hg), and new invasive species, such as the hemlock wooly adelgid, emerald ash borer, and Asian long horned beetle, whose ranges are likely to expand within the region. Bartlett Experimental Forest also represents the most Northeastern NEON site, and anchors the top of the north-south nitrogen deposition gradient along the eastern-side of the US.
