Site Description
Treehaven (TREE) is a NEON terrestrial field site located in Lincoln county, Wisconsin between the cities of Rhinelander and Tomahawk. The 4.7 km2 (1160 acre) site is hosted and operated by the University of Wisconsin – Stevens Point (UWSP), College of Natural Resources. The primary land cover types at this site are woody wetlands, mixed forest and deciduous forest. This site is approximately 1.6 km (1 mi.) south of the relocatable terrestrial site Steigerwaldt (STEI), which is managed by Steigerwaldt Land Services, Inc. The close proximity and different management plans for the two sites could lead to valuable data on the effects of different management practices on carbon cycling dynamics. TREE is located within NEON's Great Lakes Domain (D05), which includes northern Ohio, Michigan, northern Wisconsin, and parts of Indiana and Illinois. D05 hosts four other NEON field sites: two aquatic and two terrestrial, located in Wisconsin and Michigan.

Geology
This site’s bedrock is classified as Early Proterozoic mafic to felsic metavolcanic rock that is underlain by gneiss in some areas. The surface materials are loamy till from the Wildcat Lake Member of the Copper Falls Formation and meltwater stream sediment from the Wisconsin Valley Lobe. The primary parent material of this site is sandy outwash.
Vegetation
The lowlands of this area consist of mixes of black spruce (Picea mariana) and tamarack (Larix laricina) forests, non-forested acid bog environments, and hardwood and cedar wetlands. The upland sites feature aspen (Populus tremuloides), paper birch (Betula papyrifera), and red maple (Acer rubrum). The upland sites also contain red pine (Pinus resinosa), white pine (Pinus strobus), white spruce (Picea glauca), and balsam fir (Abies balsamea). Overall, sugar maple (Acer saccharum), red maple (Acer Rubrum), balsam fir (Abies balsamea), grey alder (Alnus incana), and Pennsylvania sedge (Carex pensylvanica) are the most dominant species in this site.
Soils
The parent material at the site is sandy outwash and soils that are Vilas and Sayner loamy sands. Some areas are also underlain by coarse-loamy till, which leads to a slightly higher productivity in some tree species. This area is also slightly less droughty and has a higher productivity due to a thin loamy mantle in several sites that is not typically found in Vilas or Sayner soils. Soils at TREE are part of the subgroup Alfic Haplorthods.
Hydrology
Treehaven has glacial topography that consists of glacial moraines and outwash features. Pickerel Creek flows into the site from the North and eventually merges with Big Pine Creek, which flows into the site from the northeast and out through the southwest. These both mainly feature warm water and muddy bottom habitats. This area also includes several small vernal pools and lakes.
