Treehaven (TREE)

The 560-ha Treehaven Forest lies within the northern Great Lakes region south of Rhinelander, Wisconsin. Operated by the University of Wisconsin-Stevens Point, this site focuses on natural resource education.  The area includes an ancient glacial ridge with surrounding forest and wetlands. The site visit was facilitated by Peter Weishampel, NEON domain manager.

Plot 6 is an open stand near road access. The dominant species include Pinus strobus, Pinus resinosa, Picea glauca, Acer rubrum and Populus tremuloides. This recently burned site now supports a dense herbaceous layer of ferns, thistles, and briars.

Bog area in Plot 15

Plot 15 is located on a hillslope with Abies balsamea and A. rubra that descends to a bog with Thuja occidentalis. Ferns, moss and A. balsameaseedlings line the forest floor.

Lone P. strobus in plot 5

Plot 5 extends from a river bank. The canopy consists of one large P. strobusabove dense 4-m tall speckled alder and sawgrass in the herbaceous layer. Animal paths are evident throughout the sawgrass.

Plot 7 is located in a dense field of 2 to 3 m tall P. tremuloides saplings. The open canopy consists of two large P. resinosatrees.

Plot 2 is a recently thinned stand of P. strobus. The understory consists of A. rubrum, ferns, briars, with young A. balsamea and P. glauca trees. To include the sparse P. strobus canopy we mapped trees in the 40 x 40 meter area.

Plot 14 slopes from an open stand in the northwest downhill to dense 5 m tall aspen saplings. The canopy supports a mixture of Prunus serotine, A. rubrum, P. resinosa and A. balsamea, which have not yet reached maturity.

Plot 1 includes recently thinned P. strobus sloping steeply from P. glauca and A. rubrum in the north to a creek fringed with A. balsamea.  Despite the size of large P. strobus trees few cones were detected.

Open savannah in plot 3

Plot 3 is an open savannah with a grass and fern herbaceous layer. The canopy is dominated by A. rubrum and A. saccharum, with a few P. tremuloides.

Plot 4 lies within a bog dominated by T. occidentalis and A. balsamea. The ground layer is covered with sphagnum moss, grasses, ferns and A. balsameaseedlings.

Plot 8 is a riparian alder stand bordering the river. The mature alders are both black and speckled with animal trails leading through the grasses between. The canopy is sparse, with few T. occidentalis loaded with cones.

Soaproot Saddle is part of the Sierra National Forest and managed by the Forest Service. Jessica Bolis, NEON domain manager, facilitated access to the plots.

Wind River Experimental Forest (WREF)

The Wind River Experimental Forest, north of the Columbia River River Gorge and part of Gifford Pinchot National Forest, has been studied by the USFS since 1908.

Yellowstone (YELL)

Parent materials combine a history of volcanism, faulting, and glaciation. The park remains seismically active, with frequent earthquakes and many hydrothermal features. Vegetation includes a mosaic of forest, sagebrush-steppe and riparian bottomlands.

Bartlett Forest (BART)

Bartlett Experimental Forest (BART), located in the White Mountains National Forest, New Hampshire, is managed as the U.S. Forest Service, Northern Research Station.

Harvard Forest (HARV)

Sampling at Harvard Forest includes long term plots established by our lab in 2012 and new efforts located at NEON plots.

Mountain Lake Biological Station (MLBS)

Mountain Lake Biological Station is located in the Southern Appalachians of Southwest Virginia. This field site is administered through the University of Virginia. The NEON plots extend from mixed decidious forests to pine plantations.

Smithsonian Environmental Research Center (SERC)

Smithsonian Environmental Research Center is located south of Annapolis, MA. Formally farmland, this coastal plain forest sits on the western shore of the Chesapeake bay. The 1070-ha site is operated by the Smithsonian Institute.

Talladega National Forest (TALL)

The Talladega NEON site is located within the Oakmulgee Ranger District of the Talladega National Forest. This rolling terrain is part of the Fall Line Hills of the Eastern Gulf Coastal Plain. In the 1800’s this area was heavily logged, but since the 1980’s the Forest Service has worked on restoring this area back to the Longleaf Savannah ecosystem.

Ordway-Swisher Biological Station (OSBS)

The University of Florida hosts the NEON OSBS site at their Ordway-Swisher Biological Station in north-central Florida. Andrew Rappe, the Assistant Director, gave us an orientation to the site.

Disney Wilderness Preserve (DSNY)

Formerly ranchland, the Disney Wilderness Preserve has been restored to Pine savanna under ownership of The Nature Conservancy. Previously, most of the preserve consisted of flatwoods open to cattle and excluded from fire.

Niwot Ridge (NIWO)

Niwot Ridge is an LTER site administered through University of Colorado’s Institute of Arctic and Alpine Research (INSTAAR)at their Mountain Research Station. NEON sites extend from P. contorta and subalpine spruce-fir to above treeline.
