Summary:
Tree and liana (vine) measurements were collected in a logging concession at the Fazenda Rohsamar in the municipality of Jurena in northwestern Mato Grosso. Tree identification and diameter measurements were collected between July 31, 2003 and October 14, 2003 on 10 10-m x 1000-m transects and the liana measurements were collected between August 5, 2003 and October 14, 2003 on 10 2-m x 1000-m transects within a 1400 ha logging block ( Feldpauschh et al. 2006). Liana transects were nested within tree census transects to relate total species data to the tree inventory. The biomass of lianas was calculated using two different allometric equations derived for lianas in Amazonian forests (Gerwing and Farias, 2000; Gerwing et al. 2004). Comma-separated data files (.csv) of measurements of (1) tree species (diameter >10 cm), and forest characteristics, (2) measurements of liana diameter, forest characteristics, and calculated biomass, and (3) georeference points for the liana sampling transects are provided.
Selective logging has become a dominant land-use in Brazilian Amazonia. Published data on forest biomass in southern Amazonia is sparse. As part of a larger study to evaluate the effect of reduced impact logging on carbon dynamics and nutrient stocks, forest structure, and forest regeneration potential, we conducted a pre-harvest campaign to estimate tree and liana biomass in a parcel of managed forest in northwestern Mato Grosso. Prior to logging in 2003, a scientific inventory was conducted in Block 5 of the logging concession (Figure 1). Tree characteristics for all trees and palms > 10 cm DBH was measured by stratified sampling across the block to account for differences in tree densities (trees/ha). Transects were located using a commercial timber inventory to identify tree trunks approximately 10 cm DBH, lower and upper canopy height, species, and location of all individuals to the nearest 10 cm on an x-y grid. Diameter of all liana stems were included if their ultimate rooting point before ascending into the canopy fell within the transect. Lianas that had been cut due to reduced impact logging practices were also measured. Distance along the transect was recorded for each stem.
Figure 1. LANDSAT TM image (acquired July 1996) showing the location of the logging concession at Fazenda Rosahmar adjacent to the Rio Juruena in the county of Juruena in southern Amazonia, MT, Brazil. Boundaries are shown for Blocks 4, 5, and 18. Pink areas inside the concession indicate low-stature vegetation. Pink areas outside the concession are deforested and are most frequently pastures. Aqua blue areas indicate low-lying areas or water. Green areas are native forest vegetation. From Feldpausch et al., 2006.

3. Data Application and Derivation:
Tree and liana stems were included if their ultimate rooting point before ascending into the canopy fell within the 2-m (liana) or 10-m (tree) wide transect. Furthermore, lianas that had been cut due to reduced impact logging practices were measured. The biomass of lianas was calculated using two different allometric equations derived for lianas in Amazonian forests (Gerwing and Farias 2000; Gehring et al. 2004).
The methods developed in this study could be useful for facilitating commercial inventory practices, understanding the relationship of tree species distribution to landscape features, and improving the novel use of CTIs to estimate AGB (Feldpausch, et al 2006).
4. Quality Assessment:
Care should be taken in using tree taxonomic data since local names were converted to Latin names for species identification.
5. Data Acquisition Materials and Methods:
The research focused on three areas, Blocks 4 (1137 ha), 5 (1397 ha), and 18 (1037 ha), harvested in 2002, 2003, and 2004, respectively. Data were collected in logging concession at the Fazenda Rohsamar in the municipality of Juruena in northwestern Mato Grosso. Tree diameter data were collected between July 31, 2003 and October 14, 2003 while the liana measurements were done between August 5, 2003 and October 14, 2003. Tree measurements were done in 10 10-m x 1000-m plots within a 1400 ha logging block and liana measurements were done on 10 2-m x 1000-m transects within the tree transects.
Tree identification and diameter measurements were done in 10 10-m x 1000-m plots within a 1400 ha logging block while liana measurements were done on 10 2-m x 1000-m transects within the same logging block. Diameter of all liana stems were included if their ultimate rooting point before ascending into the canopy fell within the transect. Furthermore, lianas that had been cut due to reduced impact logging practices were measured. The biomass of lianas was calculated using two different allometric equations derived for lianas in Amazonian forests (Gerwing and Farias 2000; Gehring et al. 2004).
Tree diameter measured at 1.3 m height or above prop roots or buttresses using a fiberglass measuring tape. Prior to logging in 2003, a scientific inventory was conducted in Block 5. Tree characteristics and AGB for all trees and palms ~ 10 cm DBH was measured by stratified sampling across the block to account for differences in tree densities (trees/ha). Using the commercial timber inventory to identify tree density variation across the block, we located eight long (10-m x 1000-m) and eight short (10-m x 200–500-m) belt transects. Within each georeferenced transect we measured DBH of all trees and palms with trunks ~10 cm DBH, lower and upper canopy height, species, and location of all individuals to the nearest 10 cm on an x–y grid. Canopy height was measured with a Haglof Vertex III-60 ultrasonic hypsometer calibrated at ambient temperature to compensate for the effect of air density on transmission time.
