TL;DR: In this paper, the effects of mineral soil properties on understory plant species richness propagated through a network of processes involving the forest overstory, soil organic matter, soil nitrogen, and under-story plant abundance.

TL;DR: In this paper, a linear aggregate model of variables controlling radial growth response of southwestern ponderosa pines to fire was proposed to determine which variable would best model growth, post-fire growth (19771984 ) was correlated with the 3 year average of previous growth, crown ratio, competition index, and diameter.

TL;DR: In this paper, the authors installed 20 point-intercept transects (50-m long), 8 belt tranchs (10 � 50 m), 10 adapted Daubenmire tranects (four 0.5 � 2-m plots), and 4 modified-Whittaker plots (20 � 50m with smaller nested plots) in treatment and control units to measure understory herbaceous response in a forest restoration experiment that tested different treatments.

TL;DR: Additional sampling-design studies are needed to develop single sampling designs that produce multifactor data on plant composition, diversity, and spatial patterns amenable to multivariate analyses as part of monitoring plans of vegetation responses to ecological restoration.

TL;DR: In this paper, a mixed-species temperate forest was studied and the authors found that the leaf biomass reflects important developmental differences in both primary production and nutrient cycling between stands, and that leaf biomass is an important component of forest ecosystems.
