Information Management

Information management at the Hubbard Brook Ecosystem Study (HBES) is run by the Information Oversight Committee (IOC), which meets two times a year. One meeting is held during the summer at the Hubbard Brook Experimental Forest around the time of the annual HBES cooperators' meeting. The other meeting is timed to coincide with the winter HBES Committee of Scientists meeting in January, usually at the Institute of Ecosystem Studies in Millbrook, NY. Occasionally, additional ad hoc information management meetings are necessarily and are scheduled accordingly.

Data Use

The Hubbard Brook Ecosystem Study adheres to the LTER network data use policy that was approved by the LTER Coordinating Committee on April 6, 2005. A complete copy of the policy can be downloaded from the LTER website (

Conditions of Use for Hubbard Brook Data
The re-use of scientific data has the potential to greatly increase communication, collaboration and synthesis within and among disciplines, and thus is fostered, supported and encouraged. Permission to use this dataset is granted to the Data User free of charge subject to the following terms:
(1) Acceptable use. Use of the dataset will be restricted to academic, research, government or other not-for-profit professional purposes. (2) Redistribution. The data and metadata are provided for use by the Data User. The Data User will not redistribute the original Data Set or metadata to others without the explicit permission of the Principal Investigator. (3) Citation. It is considered a matter of professional ethics to acknowledge the work of other scientists. Thus, the Data User will properly attribute the Data Set in any publications or in the metadata of any derived data products that were produced using the Data Set. Citation should take the following general form: Creator, Year of Data Publication, Title of Dataset, Publisher, Dataset identifier. For example:
Holmes, R.T. 2012. Bird Abundances at Hubbard Brook (1969-2010) and on three replicate plots (1986-2000) in the White Mountain National Forest. Durham, NH. Hubbard Brook Data Archive [Database]. (23 July 2012) (4) Acknowledgement. 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.
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. 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". The Data User holds all parties involved in the production or distribution of the Data Set harmless for damages resulting from its use or interpretation. (8) Terms of Agreement. By accepting this Data Set, the Data User agrees to abide by the terms of this agreement. The Data Owner shall have the right to terminate this agreement immediately by written notice upon the Data User's breach of, or non-compliance with, any of its terms. The Data User may be held responsible for any misuse that is caused or encouraged by the Data User's failure to abide by the terms of this agreement.

Data Backup

At the Hubbard Brook Ecosystem Study, individual scientists are responsible for backing up their own data. Data on the HBES website are backed up regularly by the HBES information manager. Beyond that, we strongly recommend that scientists follow the backup guidelines listed below to ensure that valuable HBES data are not lost. We also offer the option of storing backups (tapes, CDs, etc.) in a temperature-controlled, fire-resistant vault at the US Forest Service office in Durham, NH. The vault remains locked and the backups will not be made available to others. If you have questions about storing your backups at the Forest Service, please contact John Campbell

Disks or tapes can be submitted to:
John Campbell, U.S. Forest Service
271 Mast Road, Durham, NH 03801
Tel.: (603)868-7643

Data Backup Guidelines
Check with your computer support staff to see what backup options may be available to you through your institution.

Develop a written backup plan that lists who is responsible for backups, what is being backed up, the number of backup copies made, and where the backups are stored. We encourage you to send your written plan to the HBES Information Manager at the address above for storage at the Forest Service vault in Durham. This information will enable us to recover Hubbard Brook data in the event that something happens to a researcher or facility.

Set a schedule for backing up data and stick to it.

Maintain a written backup log of what was backed up, when the backup occurred, and who conducted the backup.

Do not always overwrite the same disk or tape. Archive disks or tapes periodically (e.g., monthly) so that you can go back and determine if and when errors occurred.

Properly label disks or tapes with permanent marker.

Test your backups before you need them. Perform trial restorations periodically to verify that your files were properly backed up.

Keep at least one copy of the backup offsite in a properly controlled environment in case of site-specific disasters such as fire or flood. Make sure other people know where that backup is stored.

Select the correct backup medium for the job. (e.g., floppy disks can hold only a small amount of data and are prone to failure; CDs can hold up to around 800Mb, but can degrade over time; USB sticks with built-in backup software are coming down in price and are available in large capacity form ; some companies are offering on-line web server data backup; a technology called RAID (Redundant Array of Independent Disks), copies all files to a second hard drive as they are created.

There are many backup device options. Choose the one that is right for you and use it.

Physical Sample Archive

An archive facility was built at the Hubbard Brook Experimental Forest to store samples permanently so that they will be available for future research. The building now houses approximately 40,000 samples of soil, water, plant tissue, and other materials. See the Archived Samples page for more information.

Document Archive

The Institute of Ecosystem Studies in Millbrook, NY maintains a document archives of Hubbard Brook Ecosystem Study materials, including publications, theses, correspondence and photos. Copies of publications and theses are also available at Pleasant View Farm for student use.

To ensure that these materials are available to others, researchers are required to submit citaion information and pdfs of all Hubbard Brook publications to the Hubbard Brook Information Manager.
