They can then predict whether a severely burned site is likely to meet a desired level of tree density five to seven years later. (sciencedaily.com)
With respect to why there was a significant increase in tree density over the past several decades, Dolanc offers that the changes in the density and composition of lower - elevation forests are consistent with fire suppression; but that the density increases in high - elevation vegetation types (subalpine forests generally don't burn) are «more likely to be caused by changing climate.» (cato.org)
While tree density increased by 0.3 percent per year in two decades, liana density rose tenfold. (discovermagazine.com)
