Sentence examples for estimates of stand from inspiring English sources

Stand age is then cross-tabulated with estimates of stand height and aboveground biomass from lidar remote sensing.

Understorey light availability was highly variable across all levels of residual basal area with estimates of stand structure, including density (N), basal area (G) and stand density index (SDI) explaining 37.2 52.1% of population level variation.

LiDAR data are used operationally in, for example, the Nordic countries, to provide estimates of stand dimensions at the compartment level (Eid et al., 2004).

The analysis was based on diameter distribution, spatial pattern of aspen trees and reliability figures of forest attribute estimates of stand level inventory.

Internationally, LiDAR data have been used within the forest sector to provide estimates of stand height, basal area (Means et al., 1999; Watt, 2005), stem diameter, stem volume (Lim et al., 2003; Lim & Treitz, 2004; Naesset, 1997; Woods et al., 2008; Woods et al., 2011) canopy properties (Naesset & Okland, 2002) and species composition (Donoghue et al., 2007).

Quantitatively the differences between estimates of stand parameters are not statistically significant (except for BA - this result was also found in Hudak et al. [52] and they postulate that this bias is a result of the natural logarithm transformations and back transformations).

Physiological studies will be necessary to further refine estimates of stand-level carbon balance and to make long-term predictions of changes in carbon balance due to changes in forest structure, species composition, and climate.

Best estimate of stand size (if over 200+ trees)?

Plot level characteristics include a measure of stand age, either estimated by researchers or obtained from coring information, and an estimate of stand aspect, taken as the direction of slope of the subplot to the nearest degree determined along the direction of slope with North set as 360.

For example, PnET-II estimates components of stand water balance (Aber and Federer 1992), which determines the degree of water stress and subsequent declines in net photosynthesis.

Soares & Tomé (2004) [35] found analogous trends and concluded from their study on effectiveness of biomass expansion factors that estimates of total stand biomass (aboveground and root biomass) should be derived from allometric equations and if an expansion factor must used then age-dependent BEFs are recommended.
