Bartlett Experimental Forest - United States of America
Bartlett Experimental Forest
United States of America
The Bartlett Experimental Forest is relocateable site in Domain 01 Northeast and the site is part of NOEN'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. Total data products collected at this site is 116. Airborne remote sensing surveys of this field site collect collect lidar, spectrometer and high-resolution RGB camera data. The flux/meterological

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.
The Bartlett forest has a history of logging dating from colonial times through the beginning of the 20th century. Approximately 70% of the land area has remained uncut since the early 1900s. Natural disturbances include late 19th century fire, beech scale-Nectria complex (beech bark disease) beginning in the 1940s, severe wind disturbance resulting from hurricanes in 1938 and 1954 and a damaging ice storm in 1998.
