BOREAS TE-13 Biometry Data The Boreal Ecosystem-Atmosphere Study (BOREAS) Terrestrial Ecology (TE)-13 collected data on site characteristics, soil profiles, woody debris, overstory vegetation, and understory vegetation from approximately 100 sites in the Southern Study Area (SSA), Northern Study Area (NSA), and Transect Areas in the boreal forest. This information is supplied in three Forestry Canada documents that are included on the BOREAS CD-ROM series as Portable Display Format (PDF) files: BOReal Ecosystem-Atmosphere Study (BOREAS) Biometry and Auxiliary Sites: Overstory and Understory Data (TE13_BOREAS_CANOPY.PDF) BOReal Ecosystem-Atmosphere Study (BOREAS) Biometry and Auxiliary Sites: Locations and Descriptions (TE13_BOREAS_SITE_LOC.PDF) BOReal Ecosystem-Atmosphere Study (BOREAS) Biometry and Auxiliary Sites: Soils and Detritus data (TE13_BOREAS_SOILS.PDF) All of these documents include background information, methods, equations, explanation of terms and acronyms. The data are given in the form of tables and maps in the PDF files and may be viewed using Acrobat Reader, which is provided on the BOREAS CD-ROM and can be obtained from the Adobe website, http://www.adobe.com/. Using Acrobat Reader, data may be copied from the document and pasted as text into a word processing or spreadsheet program. The three reports are available free of charge from: Publications Canadian Forest Service 5320-122nd Street Edmonton, Alberta T6H 3S5 Canada (403) 435-7210 (403) 435-7359 (fax) dleroy@nrcan.gc.ca The Biometry and Auxiliary Sites Overstory and Understory Data consists of two sections: overstory and understory. Overstory vegetation was defined as vegetation taller than breast height, which were typically trees and occasionally shrubs. Understory vegetation was divided into three classes. In 1993, the shortest class ranged from 0 m (ground) to 0.05 m consisting mainly of lichen, mosses, and short herbs, the middle class ranged from 0.05 m to 1.0 m, and the tallest class ranged from 1.0 m to 2.5 m. In 1994, the middle class expanded its range to 1.5 m and the tallest class ranged from 1.5 m to 2.5 m. For each site, three tables are given: stand values, individual tree values, and field data from cored trees. Stand values included the date of measurement at each plot, sampling method (point or fixed area plot), basal area, stem density, stem volume, and biomass. A graph of the diameter at breast height (DBH) versus mean stem density and versus biomass is given for each site. Individual tree values included the tree number, species, diameter at breast height, and canopy class. Field data from cored trees included the tree number, species, diameter at breast height, number of rings, tree height, height to the base of the live crown, live crown width, sapwood thickness, number of sapwood rings, and bark thickness. In Biometry and Auxiliary Sites Location and Descriptions, the site information is divided into four sections: NSA Auxiliary Sites, SSA Auxiliary Sites, Transect Sites, and Tower Sites. The following information is provided for each site: directions, map showing its location, site description, coordinates, classification, percent species at the site, and the locations of the Tie-in- Point (TIP) and any plots at the site. The sites are listed alphabetically by CFS site code. On page 9 in the document, there is a cross reference table giving the BOREAS Operational Grid Identification and CFS site code for each site. See the Site Reference information to relate the Operational Grid Identification to the Final Site Identification. The Biometry and Auxiliary Sites Soils and Detritus Data document is divided into two sections: Soils and Detritus. The soil section describes the soil profile of the soil pit and describes the characteristics of each soil horizon in each profile. For each soil pit, the following information is given: site code, BOREAS Operational Grid Identification, latitude, longitude, plot , soil type, landform, drainage, moisture, depth to bedrock, depth to carbonates, depth to water table, depth of effective rooting, and depth of root restriction. For each soil horizon, the following information is given: soil horizon, upper depth, thickness, color, structure, texture. mottling, effervescence, root characteristics (abundance, size, and orientation), Van Post Scale (an assessment of decomposition), and bulk density. The detritus section of the document includes tables giving the site code, BOREAS Operational Grid Identification, stratum, plot. volume of debris and total detrital mass for all size classes combined, mean duff depth, and intersections, volume, and detrital mass are given for each size individual size classes. For individual debris items having a diameter greater than seven cm, species, diameter at the point of intersection, and condition (state of decomposition) were also provided. 1.
