A conversation at LEAFFEST (publiclaboratory.org/notes/leaffest
) was inspired by the pan/tilt kite aerial photography (KAP) rig we flew, and eventually hatched a plan to build an inexpensive Arduino-based version for ground-based time-lapse photography. So I dragged out the old Gigapan Epic 100 and took a quick ...-

On March 20 this sugar house is usually in full operation boiling sap into maple syrup. The sap runs on bright days after freezing nights, but this year, a week of hot days and warm nights ended the run three or four weeks early. Although this is one of the more authentic sugaring operations in Vermont, it felt strange...

The floating peat mat to the left supports some plants rarely found outside of cold, nutrient poor, peat bogs. Where the two-meter thick peat mat is not floating, trees and tall shrubs outcompete the bog plants. Much of the 50 acres of peatland surrounding Molly Bog supports a conifer swamp with spruce, larch, hemloc...

The apparent levee along the shoreline of Molly Pond is vegetative, not geomorphic. Leatherleaf grows tall at the edge of the floating peat mat which has been encroaching into this kettle pond for thousands of years. The floating mat is about two meters thick in the foreground and supported my weight well, but I had t...

Looking toward a gap in a stand of large eastern hemlock and red spruce near Roaring Brook in the Adirondack mountains of New York. Counts of tree rings nearby confirm that the ages of many trees in this stand approach 400 years. These ages, and the large number of dead standing and fallen trunks suggest that this is ...

During World War II this hillside was a cow pasture. After the war it was abandoned, and by 1960 a forest of young white pines had closed its canopy over the field. Some of the slower growing pines have since died, and the canopy opened to admit enough light for many sugar maple seedlings to germinate and establish i...

There are several dozen examples of this forest community in Vermont, most of them less than a few hectares in size. This is the most recently discovered example. The community is distinguished by the presence of pitch pine, which reaches its northern range limit in Vermont, and occurs in only three community types i...

I compared three methods of determining basal area (cross sectional area of trunks) in this stand of Alaskan birch at the Bonanza Creek LTER site near Fairbanks, Alaska. The diameter of each birch tree was measured in a 42 x 38 m plot surrounding this and two other sample/photo points. This provided a measure of the ...
