PACIFIC ISLANDS PNW-FIADB User’s Manual A data dictionary and user guide for the Pacific Islands PNW-FIADB database Inventory Data for the Pacific Islands The Pacific Northwest Forest Inventory and Analysis Database The database includes data for: America Samoa Guam Palau Hawaii (documented here; data to be compiled in 2015) For more information or help, please contact : Olaf Kuegler 503-808-2028 [email protected] Jane Reid 907-743-9411 [email protected] Ashley Lehman 907-743-9415 [email protected] Sharon Stanton 503-808-2019 [email protected] Forest Inventory and Analysis Pacific Northwest Research Station Portland, Oregon This documentation is based on the National FIADB manual A customized version for the Pacific Northwest FIA program Foreword The mission of Forest Inventory and Analysis (FIA) is to determine the status and trend in forest resources. FIA is a continuing endeavor mandated by Congress in the Forest and Rangeland Renewable Resources Planning Act of 1974 and the McSweeney‐McNary Forest Research Act of 1928. The USDA Forest Service, Pacific Northwest Research Station is responsible for conducting inventories in the U.S. affiliated Pacific Islands. Specifically, the Forest Inventory and Analysis program within the Resource Monitoring and Assessment Program (known as RMA‐FIA), collects data in cooperation and collaboration with Island governments, land owners, and citizens; compiles data and creates databases for distribution to the public; and publishes summary reports to document and interpret the information. The island groups inventoried by RMA‐FIA include American Samoa, Guam, Hawaii, the Republic of Palau, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia, and the Republic of the Marshall Islands. Note that older data are being reorganized to fit into the current database structure, and will be added to the database over time. Currently the database includes data for American Samoa, Guam, and Palau. This data dictionary provides details on database structure, column definitions, valid codes, and more. All inventories strive to use a common plot design and common data collection procedures, resulting in consistency among the Pacific Islands and mainland United States. When things differ between Islands or the Inventory Year, data column definitions will note inconsistencies caused by different sampling designs and processing methods. The PNW‐FIADB is a customization of the national database structure. It contains inventory data collected and compiled with national protocol and algorithms, as well as regional data that are collected only by the PNW RMA‐FIA program and only in the Pacific Islands. Data columns that do not pertain to the PNW or Pacific Islands have been deleted from tables in this database. And, columns are reorganized and sorted by name to make it easier to find an individual column. Some frequently used columns have been moved to the beginning of each table. The PNW RMA‐FIA program hopes this customized version of the FIADB will simplify the use of FIA inventory data, and that analysts and other interested individuals will turn to the PNW‐FIADB when data are needed for projects and analyses of Pacific Island forests. Inventory data for plots in this database: Island Group Initial measurement Re‐measurement America Samoa 2001 2012 Guam 2002 2013 Palau 2003 2014 2010‐2014 Hawaii (may not be included in the database at the time of this printing) Although we have reviewed the data and documentation extensively, if you find any errors, typos, or other problems with anything in the PNW‐FIADB package, we would appreciate it if you would let us know.
