Abstract:

Abstract

An ice storm simulation was performed at the Hubbard Brook Experimental Forest to evaluate impacts of these extreme weather events on northern hardwood forests. Water was pumped from the main branch of Hubbard Brook and sprayed above the forest canopy in subfreezing conditions so that it rained down and froze on contact with trees. The experiment consisted of five treatments, including a control (no ice) and three target levels of radial ice accretion: low (6.4 mm), mid (12.7 mm), and high (19.0 mm). Two of the mid-level treatment plots (midx2) were iced in back-to-back years to evaluate impacts of consecutive storms. This dataset consists of hemispherical photographs of the forest canopy with leaves on and off the trees before and after the various ice treatments.

These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Description:

Methods

Ice was applied to 20 x 30 m plots and the hemispherical canopy photographs were taken on the center line, 5 m in from the north and south side of each plot. All images were taken with a Nikon D3200 camera (Nikon, Tokyo, Japan) outfitted with a 5.8 mm 180° circular fisheye lens. The camera was mounted on a self-leveling monopod 1.5 m above the ground. Attempts were made to collect images at different exposures under uniform, diffuse sky conditions. The dataset includes both pre- and post-treatment images with leaves on and off the trees.
