Pine-Oak-Heath-Sandplain Forest, Salisbury, Vermont -- Due to the presence of pitch pine, this is one of the rarest forest communities in Vermont, known only from the deltaic sandplains of Colchester (gigapan.org/gigapans/30324/) and this stand in the Salisbury Town Forest. The parent material for the droughty, acid soils is a 13,600 year old deposit of sand and gravel that is about 20 m deep here (an exposure of the deltaic strata under this surface can be seen here: gigapan.org/gigapans/34814/). Students at Middlebury College under the direction of Matt Landis have been describing the forest composition and population structure of this stand, and addressing questions about its disturbance history and the probable fate of the pitch pines. Results suggest that pitch pines have not reproduced in this part of the stand for many decades, and that many of the large pitch pines are dying. Most trees marked with flagging in this view are pitch pines.

Shutter speed was altered between 0.4 (top 3 rows) and 0.8 (bottom 3 rows) seconds. Two second shutter delay was initiated by wireless remote. Field of view set to 9.8 degrees. Exposure, vibrance, and saturation of photos were adjusted in Lightroom before outputting jpegs for stitching.

    Thanks John. I'm glad you have found these GigaPans interesting. I am still climbing the learning curve. Each new forest requires a different set of choices (scene, lighting, whether to vary focus and exposure), and I rarely get it right. But I am enjoying the challenge of optimizing depth of field and resolution in scenes of different geometries. It has forced me to learn a lot about photography (not to mention forests).

    You have made a remarkable series of images of habitat. The detail is amazing. As I am involved in floristic inventories here in Florida the use of panoramas presents some interesting possabilities. You have mastered a high level of photography and Gigapan skill. How steep was the learning curve?
