Title: Hubbard Brook Experimental Forest: Lichen grazing assessment on valleywide plots
Herbivory by terrestrial gastropods, particularly Arion sp. (a non-native slug), can alter epiphytic lichen communities; however, little is known about this interaction in forests of North America. We used surveys of grazing damage to lichen thalli in the field on 52 plots within Hubbard Brook Experimental Forest, NH. Grazing damage by terrestrial gastropods was widespread, though few sites had severe grazing. Grazing damage was significantly higher on flatter terrain and on broadleaf trees. Overall, lichen communities in the HBEF were moderately impacted by terrestrial gastropod grazing, but potential effects of the non-native slugs at higher elevations and impacts on lichen health of widespread, moderate grazing deserve further study. 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. These data were analyzed and published in: Clyne, Ailís B, Natalie L Cleavitt, and Timothy J Fahey. 2019. “Terrestrial Gastropod Grazing On Macrolichens In A Northern Broadleaf–Conifer Forest”.

    Herbivory by terrestrial gastropods, particularly Arion sp., can alter lichen communities; however, little is known about this interaction in forests of North America. This data set reports the results of two feeding trials with slugs and snails from Hubbard Brook on seven lichen species. In feeding trials two common lichens, Hypogymnia physodes and Platismatia glauca, were grazed more heavily by both native and non-native slugs than other lichen species.

    Declining nitrogen (N) availability relative to plant demand, known as N oligotrophication, is a widespread phenomenon that has been particularly well documented in northern hardwood forests of the northeast U.S. It is hypothesized that later fall senescence contributes to this trend by increasing tree resorption of N, resulting in higher carbon:nitrogen ratios (C:N) in litterfall and reduced N availability in soil. To examine the effects of litterfall C:N on soil N cycling, we conducted a litter quality manipulation experiment comparing low C:N and high C:N litter with native litter along an elevation and aspect gradient at Hubbard Brook Experimental Forest, NH, USA. We found that potential net ammonification and mineralization rates were positively correlated with litter N and negatively correlated with litter C:N under high C:N litter, but these relationships were not present under native or low C:N litter. Differences in nitrate pools and net mineralization rates between high- and low-quality litter treatments were greater at colder sites where native litterfall tends to have lower C:N than at low elevation sites. Together, these results demonstrate that higher C:N litter and a warming climate likely contribute to N oligotrophication through effects on microbially driven N cycling rates in organic soils. 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.

    To evaluate the effects of ice storm disturbance on forest canopy structure and complexity terrestrial lidar data were collected within the Hubbard Brook Ice Storm Experiment plots starting in 2015 (prior to ice treatment) and annually thereafter. Data were collected using a ground-based portable canopy lidar (PCL) system during the growing season in August of each year along 5 permanently marked 30 m transects in each 20 x 30 m ISE plot. 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.

    Air temperature is measured at seven locations in rain gage clearings throughout the experimental watersheds and at Headquarters. The oldest air temperature record dates back to October 20,1955 at Station 1. From 1955 - 2014, temperature measurements were made continuously using hygrothermographs housed in standard shelters. Beginning in 2014, digital sensors housed in solar radiation shields collected daily minimum and maximum temperature measurements. Measurements made by the hygrothermographs have been corrected for screen bias to match the current aspirated radiation shields. 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.
