Summary The BOREAS TE-23 team collected map plot data in support of its efforts to characterize and interpret information on canopy architecture and understory cover at the BOREAS tower flux sites and selected auxiliary sites from May to August 1994. Mapped plots (typical dimensions 50 m x 60 m) were set up and characterized at all BOREAS forested tower flux and selected auxiliary sites. Detailed measurement of the mapped plots included: • stand characteristics (location, density, basal area) • map locations DBH of all trees • detailed geometric measures of a subset of trees (height, crown dimensions) • understory cover maps. The data are stored

Overview

1.1 Data Set Identification BOREAS TE-23 Map Plot Data 1.2 Data Set Introduction This canopy architecture and understory cover data set provides BOReal Ecosystem-Atmosphere Study (BOREAS) investigators with a common ground-truth site characterization for the major study sites at tree and stand levels, and provides links between the various disciplines involved in BOREAS. Mapped plots (typical dimensions 50 m x 60 m) were set up and characterized at all forested tower flux and selected auxiliary sites.

1.3 Objective/Purpose These mapped plots serve two general functions: • To provide comprehensive canopy architecture specific type of forest. • To provide a study area for field measurements, index (LAI), and tree population dynamics.

measurements

for a site representative

such as studies of light regime,

of a

leaf area

More specifically, the mapped plots serve as the location for: • Intercomparison and calibration of techniques used to estimate LAI, fraction of intercepted photosynthetically active radiation (FIPAR), and fraction of absorbed photosynthetically active radiation (FAPAR). • Testing geometric models concerning radiant transport in canopies. 1.4 Summary of Parameters • General information about mapped plot: study area, forest type, grid dimensions, direction and distance from flux tower or other georeferenced location, stand density, basal area, average height, average crown radius. • Measurements for all trees (> 2 m height) in the mapped plot: X-Y location in the local grid coordinate system, diameter at breast (DBH), dominance class (dominant, codominant, suppressed, juvenile, dead standing, dead leaning). • Measurements for a subset of trees: height, height to base of first branches, height to base of green crown, crown radius in four azimuth directions. • Understory cover for i0-m x 10-m subplots: hand-drawn maps of major cover classes, description of dominant species and understory features, catalog of photographs. 1.5

Discussion A total of 13 mapped plots were set up and characterized for 1) the Old Aspen (OA), Old Black Spruce (OBS), Old Jack Pine (OJP), and Young Jack Pine (YJP) tower flux sites in the Southern Study Area (SSA): 2) the OBS, OJP, and YJP tower flux sites in the Northern Study Area (NSA); 3) four locations representing a successional series within a mixed aspen - white spruce site Terrestrial Ecology (TE) tower site in the SSA; and 4) the OA TE tower site and a Young Aspen (YA) auxiliary site in the NSA. Site characterization involved setting up a reference grid, mapping and labeling individual trees, measuring basic crown geometry, and mapping understory cover. Our site characlcrization at the tree and canopy levels is part of a hierarchical sampling approach for characterization of canopy architecture (Foumier et al., 1995). This approach involves a series of three sets of scale-tailored measurements spanning from leaf to stand levels: 1) tree vectorization _andry et al., 1994), involving detailed sampling of the three-dimensional distribution of canopy elements and crown form, 21 site characterization (this data set), involving detailed measurements of individual tree location, crown geometry, and understory cover; and 3) measurement of canopy geometry as seen from beneath, in_ olx ing acquisition of a multitemporal catalog of hemispherical photographs. The tree vectorization d_,la ,,ct has been provided by R. Landry, Canada Centre for Remote Sensing (CCRS). The catalog of hcmi,pherical photographs has been provided to the BOREAS Information System (BORIS) by P,M. Rich. University of Kansas (KU) (TE-23). This text focuses on the description of the measurement,, taken for the site characterization at the crown and site level. 1.6 Related Data Sets BOREAS RSS-(_ I t)_)4 Southern Study Area Jack Pine LAI and FPAR Data BOREAS RSS-07 LAI.

Measurements

Most measurements involved simple procedures and instrumentation. However, the complete data set is large and required a labor-intensive campaign. The following brief description of all measurements is provided by category for those who are not familiar with standard forestry procedures. • X-Y locations: Location of the grid was determined based on distance and direction from a known reference location (typically the Tower Flux (TF) or TE tower). Location of each grid marker was determined by measuring distances and directions relative to other grid markers. X-Y grid coordinates of each tree within the mapped plot were determined by triangulation from distance measurements taken from two adjacent grid markers. • Height measurements: Height was calculated based on measurements of the horizontal distance from the observer to the target, the angle from the observer's eye level to the top of the target, and the angle from the observer's eye level to the base of the target. Height was then calculated as the sum of the tangent of each of the two angles times the horizontal distance. • DBH measurements: DBH was measured directly at 1.3 m ht with a diameter tape, which was marked in units of diameter (pi x circumference). • Crown radius: Crown radius was calculated by locating points directly beneath the outermost extent of the crown and then calculating the distance to the center of the trunk. • Dominance class: Dominance class (dominant, codominant, suppressed, juvenile, dead standing, dead leaning) was estimated visually based on influence of surrounding crowns on the crown of interest. • Understory cover: Understory features were characterized by I) mapping cover in 10-m by 10-m subplots; 2) calculating cover by dominant plants, lichens, and other features; 3) taking a catalog of 35-mm color photographs of each subplot.

4.1.5 Principles of Operation Distances, for the reference grid markers and tree X-Y locations, were measured using a sonic rangefinder, model Sonin Combo Pro (Sonin, Inc., Scarsdale, NY). This instrument operates in a dual unit mode, with a master and a target unit. An infrared (IR) signal is sent by the master unit in the direction of the target unit. The IR signal triggers an ultrasound signal (25 KHz) that is sent back from the target unit to the master unit and used for distance calculation. When used in dual unit mode, the rangefinder provides distance measurements with an accuracy of 99.5% for a range from 90 cm to 90 m assuming appropriate environmental conditions. Measurements made with the Sonin are affected by several factors: high levels of noise (e.g., machinery), low or high relative humidity levels (RH < 30 % or > 70 %), altitude or barometric pressure (altitude < -0.1 km or > 0. l km), and significant wind. In addition, the instrument was designed for operation in the 0 to 30 °C range. Therefore, care was taken to make measurements under favorable conditions. Other measurements were obtained using conventional forestry instruments: compasses, clinometers, diameter tapes, and 50-m fiberglass tape measures_ All azimuth measurements were collected relative to magnetic north. Corrections for magnetic declination were performed, using values published in the BOREAS Experimental Plan (Sellers and Hall, 1994) or calculated using United States Geological Survey (USGS) geomagnetism models for Canada. Real-world map coordinates were provided by BOREAS staff using a global positioning system (GPS). 4.1.6 Sensor/Instrument None given.

Specifications

4.2.1.1 Tolerance No calibration was required because of the nature of the instruments used. However, the rangefinder, compasses, and clinometers were tested to assess proper functionality. The sonic rangefinder provided distance values with 99.5% accuracy. More specifically, the manufacturer claims that for a distance of 4.27 m, the reading will be within 3 cm of the real distance. Also, an 18-m distance should be read with less than 10-cm error. The typical distance in the map plots ranged from 1 to 12 m. We tested the rangefinder measurement against tape measure for that range and found that the error was well within the manufacturer's specifications even for cases where branches were obstructing the field of view. 4.2.2 Frequency of Calibration The instrumentation was calibrated 4.2.3

Methods

The site characterization involved producing a stand map of individual crown locations and dimensions. Mapped plots, with dimensions of 50 m by 60 m (50 m by 40 m for YJP, and 40 m by 40 m for NSA-YA), were placed in areas representative of the "major canopy stratum," as determined by aerial photographs and verified on the ground. These representative stands were selected for relative homogeneity of species composition, age, and soil drainage characteristics. A grid, consisting of painted stakes placed every 10 m (every 5 m for YJP), was installed to establish the coordinate system for all measurements. Each tree in the mapped plot is labeled with numbered aluminum tags nailed in the trunk at eye level. All measured parameters refer to the tree identification numbers. Once the reference grid was set up and the trees were labeled, we produced a comprehensive site characterization that consisted of measurements of location, DBH, height, and crown extent for trees within the plot. In addition, we produce a map ofunderstory cover. First, we mapped X-Y positions of all trees relative to the grid coordinate system. Next, we measured the DBH of all trees and categorized every tree crown into a standard forestry dominance category: dominant, codominant, suppressed, juvenile, dead standing, or dead leaning. Then, we established stand-specific aIlometric relationships that permitted calculation of height and crown radius from DBH, based on a statistically significant sample of tree height and crown extent measurements. Crown extent was estimated by averaging measurements made for four azimuth directions. Where warranted, we recorded an estimate of the terrain topography. Finally, we characterized understory cover by dividing the mapped plot into 10-m by 10-m subplots, hand-drawing maps of cover by main understory features for each subplot, and identifying major plant and lichen species within each cover class. We took a catalog of color photographs, consisting of views of each 10-m by 10-m subplot and characteristic views of the canopy.

Location of the grid refers to the distance and direction from the flux tower (reference location) along the optical (Jing Chen's Remote Sensing Science (RSS)-07) transect "B" line (called the center line) in the azimuth direction from North (0 °) to the center point of the plot edge closest to the reference location. All transect lines were clearly marked by pink flags, and the sample locations within the mapped plots are marked with stakes (orange wooden stakes in most sites, blue PVC tubes at SSA-OBS). The mapped plot coordinates are marked on the stakes, with the distance from the tower as the x-coordinate and the distance from the centerline as the y-coordinate (except for SSA-OBS, where the x-coordinate of the first mapped location is 0 for consistency with the TE-20/TE-22 mapped plot). SE (135 °) or SW (225 °) refers to the direction from the tower. Width refers to dimensions of the mapped plot on either side of the optical transect "B" line, except in the case of SSA-OBS, where a "D" line is used, i.e., along the Y=20 line of the grid. Grid interval refers to spacing of grid stakes.
