Conversely, sites in which maximum tree density decreased as a function of increasing yearly PRR were considered water limited.
At a given elevation, sites in which maximum tree density increases as a function of increasing yearly PRR were considered to be temperature or energy limited.
We based our analysis on the maximum tree density found in each of over 200 environmental gradient combinations found with our area of interest, drawing from a dataset consisting of over 300,000 30 m plots and over 3 million individual trees.
We present a novel approach for performing environmental gradient analysis to address the question: is maximum potential tree density in eastern Lake Tahoe Basin, NV limited by water, temperature/energetic constraints, or both?
Life-history traits tested are wood density (WD), maximum tree size (D950.1), and mortality rates for trees ≥ 10 cm DBH (MD10 and RGRD10, respectively).
We compared stand composition and structural attributes (i.e., snag and veteran tree densities, tree size variability, and maximum tree size) at sites found to be mixed-severity, as well as those found to be high-severity after recent (<150 years) and older (⩾150 years) stand-replacing fires.
The production of wood with higher density compensated for the smaller maximum tree height in the AF stands with the consequence that standing biomass and also biomass production were not lower than in the NAF plots.
We observed strong correlation between LAI and community structural parameters (tree density, basal cover and species richness), with maximum with annual litter fall (R2 > 0.8) and aboveground biomass (AGB) (R2 > 0.75).
Phloem and air temperatures, MPB spatial impact data from USDA Forest Service aerial detection surveys, and remotely sensed host tree density data were used to parameterize the model using a maximum likelihood approach.
In our study, a significant flooding effect was however detected on wood density, which increased significantly with increasing flood height and duration, and for maximum tree height of the stands, which decreased significantly in direction of the river.
Within farms, tree density was generally higher in SM, whereas basal area and both mean and maximum height were higher in SP and DP sites.
