Site Description
Bartlett Experimental Forest (BART) is a terrestrial NEON field site located within the Saco River Valley of the White Mountain National Forest in Carroll County, New Hampshire. The 15.66 km2 (3870 acre) site is hosted by the U.S. Forest Service. The site’s soils, elevational gradient, climate, and tree species composition are typical for many forested areas throughout New England. BART also represents the most northeastern NEON site and anchors the top of the north-south nitrogen deposition gradient along the eastern side of the U.S. BART is located in the Northeast Domain (D01), which encompasses the New England and northern Eastern Seaboard states along with the northern end of the Appalachian range. D01 includes one other terrestrial site and one aquatic site.

Geology
BART is made up of White Mountain Plutonic-Volcanic Succession bedrock. The parent materials at BART are mostly ablation till, lodgment till, melt-out till, and supraglacial till derived from conway granite and gneiss.
Vegetation
Climate and glacial till soil make BART an ideal area for old-growth northern deciduous hardwoods consisting of beech (Fagus sp.) and sugar maple (Acer saccarum). White pines (Pinus strobus) are dispersed throughout the site but are primarily found in lower elevations. Softwood trees such as hemlock (Tsuga canadensis), balsam fir (Abies balsamea), and spruce are frequently found on cool steep slopes or in lower elevations with poor drainage.
Soils
The soils at BART are spodosols within the subgroup Aquic Haplorthods. They developed on glacial till derived from granite and gneiss. The major soil series on the site include Marlow, Monadnock, and Danforth. The soils are moist, but relatively well-drained. The soil organic horizon under the forest canopy ranges between 3-30 cm in thickness.
Hydrology
Due to the geology of the White Mountain National Forests, most of the locations are well drained. However, lower elevation locations may be slightly less effective at water drainage.
