Natural regeneration is an essential component of forest dynamics and the recovery of ecosystem functions. Therefore, understanding regeneration status, and how abiotic and biotic factors affect it, is important for ecological studies. This study discover... see more

Evidence indicates that the structure of Oklahoma Cross Timbers forests are in transition due to changing climate, land-use patterns, and fire suppression efforts. However, only a handful of studies have addressed the history of fire across the Oklahoma C... see more

Seasonal timing of prescribed fire and alterations to the structure and composition of fuels in savannas and woodlands can release understory hardwoods, potentially resulting in a global increase of closed-canopy forest and a loss of biodiversity. We hypo... see more

The 2002 Hayman Fire burned with mixed-severity across a 400-ha dry conifer study site in Colorado, USA, where overstory tree and surface cover attributes had been recently measured on 20 0.1-ha permanent plots. We remeasured these plots repeatedly during... see more

Aim of Study: The complex community of riparian reserve forest has become of great concern for researchers to develop more viable management strategies. The paper aimed to evaluate the current structural diversity of vegetation and its association with th... see more

We characterized the structure and tree species composition of bottomland hardwood forest at Arcadia Lake, Oklahoma County, Oklahoma. Additionally, we quantified the age structure of Fraxinus pennsylvanica Marshall (green ash) at the study site in order t... see more

The vegetative diversity between fairways (introduced patches) and out-of-bounds areas (remnant patches) were assessed at the Pineywoods Country Club in the Pineywoods Region of East Texas. Nested plots were placed along transects and canopy cover, percen... see more

The size characteristics of the Norway maple small undergrowth in different association groups of the forests of Novgorod-Sivers’k Polissia are ?nalyzed. As the trophicity of soil increases the values of static metric and dynamic morphoparameters of the u... see more

Quantitative criteria for assessing demographic sustainability of tree populations would be useful in forest conservation, as climate change and a growing complex of invasive pests are likely to drive forests outside their historic range of variability. I... see more
