ABSTRACT:
As the climate changes, it is thought that ice storms will begin to occur with increasing frequency. This project evaluates the damage and changes ice storms cause to northern hardwood forests in forest structure, nutrient cycling and carbon storage. Ten 20x30 meter plots were established in a predominately sugar maple stand, with four icing treatments and 2 control plots. This data set includes species and diameter breats height measurements of every tree with a DBH greater than or equal to 5 cm, as of June 2015. Trees will be remeasured every spring until 2019.

RESEARCH SUMMARY
A National Science Foundation (NSF) funded experiment to simulate an ice storm. As the climate changes, it is thought that ice storms will begin to occur with increasing frequency. This project aims to evaluate the damage and changes ice storms cause to northern hardwood forests in forest structure, nutrient cycling and carbon storage.
FIELD COLLECTION PROCEDURES
Ten 20x30 meter plots were established in a predominately sugar maple stand, with four icing treatments and 2 control plots:
- Low (0.25"): Plots 2, 6
- Medium (0.5"): Plots 3, 10
- Medium_2yr (0.5") 2 Years in a row: Plots 1, 8
- High: (0.75"): Plots 5, 9
- Control: Plots 4, 7
Tree measurements include species, tree health and canopy position of every tree with a DBH greater than or equal to 5 cm, as of June 2015. This data set only includes initial DBH measurements. Trees will be remeasured every spring until 2019.

4) Acknowledgment: The Data User should acknowledge any institutional support or specific funding awards referenced in the metadata accompanying this dataset in any publications where the Data Set contributed to its content. Acknowledgments should identify the supporting party, the party that received the support, and any identifying information such as grant numbers.

Acknowledgment example: Data on [topic] were provided by [name of PI] on [date]. 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, Newtown Square, PA. Significant funding for collection of these data was provided by [agency]-[grant number], [agency]-[grant number], etc.

5) Consultation and questions. Data users are strongly encouraged to consult with the Principal Investigator(s) who collected these data for further information. Also, when appropriate, Data Users should consider including the Principal Investigator as a collaborator and/or co-author in the use of these data.

6) Notification. The Data User will notify the Principal Investigator of any publication or derivative work based on the Data Set. The Data User will also provide the Principal Investigator and/or the administrator of the Hubbard Brook Ecosystem Study with a pdf or two reprints of any publication(s) resulting from use of the Data Set.

7) Disclaimer. While substantial efforts are made to ensure the accuracy of data and documentation contained in this Data Set, complete accuracy of data and metadata cannot be guaranteed. All data and metadata are made available "as is".
