A field experiment was established in a second-growth hardwood forest dominated by red oak (Quercus rubra L.) to examine the effects of shelterwood overstory density on leaf gas exchange and seedling water status of planted red oak, naturally regenerated red oak and sugar maple (Acer saccharum Marsh.) seedlings during the first growing season following harvest. Canopy cover of uncut control sta...

Recent rising public concerns about climate change and increasing energy costs have led to the need to re-evaluate forest biomass as an alternative energy feedstock. Biomass harvesting could potentially impact ecosystems in various ways, including site productivity and forest stand dynamics. Since these issues influence decision-making, the effects of biomass utilization are primary issues not ...

tain two distinct age classes in a forest. This system is generally initiated using a deferment harvest, sometimes referred to as a shelterwood or clearcut with reserves (Figure 1). The deferment harvest retains a limited basal area of canopy trees while allowing the majority of the area to regenerate. The harvest initially creates a stand that contains scattered or small groups of older trees,...

Abstract In temperate Europe, oak-dominated forests are widespread, supporting high biodiversity and providing important ecosystem services. Insufficient natural regeneration has, however, been a concern for over century. The objective of this study was to gain insights into differences in success using artificial techniques reforestation oak ( Quercus robur L.) stands. We monitored seedlings f...

We investigated the influence of shelterwood conditions on water relations and growth of loblolly pine (Pinus taeda L.) seedlings on two harsh sites in eastern Texas. Site I was harvested to provide four overstory density treatments (0, 2.3, 4.6 and 9.2 m(2) of residual basal area per ha). To quantify the effects of overstory competition, trenched and nontrenched subplots, each containing 25 on...

In the Mediterranean area, most common management of beech forests relies on shelterwood system. However, more effort has been put into developing alternative silvicultural treatments to enhance forests’ capacity provide higher ecosystem services. The crop-tree system seems perform well, particularly under economic point view. Moreover, it can quality timber from thinning interventions which ar...

Abstract We are currently witnessing significant global changes in climate conditions. cannot change the natural conditions, but with regard to sustainable landscape management, we can increase our knowledge of tree species and adapt forest management them. Surprisingly, one most affected Central Europe today is Scots pine ( Pinus sylvestris L.). The following literature review summarizes over ...

ABSTRACT Background: We analyzed if C. lusitanica can be planted in a shelterwood system with P. taeda as the shelter stratum. The study was conducted 13-yr-old stand under canopy Southern Brazil. Samples of these trees were measured terms diameter at breast height (DBH), total height, individual volume, and crown projection area. species´ growing space efficiency (GSE) also analyzed. A 10-mete...
