Abstract:

The paper deals with an experiment that was established at Opočno Experimental Station of the Forest and Game Management Research Institute (CR) in an oak small pole stage in 1952 to test whether Schaedelin&rsquo;âs (1942) tending method worked out for beech stands is suitable for oak stands. Development and growth of the oak stand without tending are analysed, and the influence of repeated positive selection and of definitive selection of target trees on the oak stand is described. The result of the 50-year experiment is that Schaedelin&rsquo;s tending method is suitable also for oa

Abstract:

AbstractAlthough beech stands are usually regenerated naturally, an area of up to 5,000 ha year−1is artificially regenerated by beech in the Czech Republic annually. Unfortunately, these stands often showed insufficient stand density and, consequently, lower quality of stems. Therefore, thinning methods developed for naturally regenerated beech stands are applicable with difficulties. The paper evaluates the data from two thinning experiments established in young artificially regenerated beech stands located in different growing conditions. In both experiments, thinning resulted in the lower a

Abstract:

Sustainable forest practices are often designed to mimic natural disturbance and successional processes, yet succession is poorly understood in many ecosystems. On northeastern Vancouver Island, the “disturbance hypothesis” is a widely assumed succession model asserting that shade-tolerant western redcedar (Thuja plicata Donn ex D. Don) and the ericaceous shrub salal (Gaultheria shallon Pursh) invade and colonize highly productive western hemlock (Tsuga heterophylla (Raf.) Sarg.) – Pacific silver fir (Abies amabilis Douglas ex J. Forbes) stands (HA) on zonal sites in the absence of stand-repla

An evaluation of how coarse woody debris (CWD) changes in quantity and quality during stand development was conducted using a 426-year chronosequence of 71 stands in sub-boreal forests in British Columbia. Additional characteristics of CWD were determined in 14 of the stands. Most stands are fire initiated and input from the predisturbance stand is critical in controlling the amounts and characteristics of CWD within young stands. Log volume declines from over 100 m3/ha in young stands (0-50 years) to just over 60 m3/ha in stands from 51 to 200 years old, and then increases to greater than 140

The main reason for the transformation of spruce monocultures at sites of mixed broadleaved forests is to create more natural relationships between the species structure of a stand and soil processes. The presented study compares humus conditions and basic growth characteristics of two mixed stands (spruce with beech and larch with beech) aged 25 years with a beech stand (aged 40 years) and spruce stand (aged 30 years). The purpose of the study is to evaluate (<I>i</I>) forms of forest floor, (<I>ii</I>) soil reaction, (<I>iii</I>) the content and total rese

Abstract:

Young forest stands from natural regeneration are characterized by high competitive pressure and dynamic changes over time, especially in the initial growth stages. Despite their increasing area in the temperate zone, they have received significantly less scientific attention than old forest stands. Therefore, our research was conducted on young, over-dense European beech (Fagus sylvatica L.) forest originating from natural regeneration, grown in central Slovakia, Western Carpathians. Repeated measurements of tree height and stem diameter measured on the base within a beech stand revealed sign

Abstract:

To examine the effects of density control and fertilization on stand growth and yield of young Douglas-fir ( Pseudotsuga menziesii (Mirb.)

Fertilizer was applied at the rate of 220 kg N·ha–1 (as urea) at stand establishment and every 4 years thereafter. Results after 12 years showed that widely spaced stands exhibited significantly larger quadratic mean diameter than did narrowly spaced stands. The densest stands initially had the greatest over

The paper highlights the evaluation results of the productivity and regeneration of stands in the Pechora forestry of the Komi Republic. At the research sites, the stands are mixed by composition and simple to complex by shape (with one or two stories). They are dominated by sphagnum spruce stands of Va - Vb quality classes. The total standing volume of stands varies from 44 to 161 m3/ha whereas the average volume increment varies from 0.49 to 1.46 m3/ha per year. The dependence of standing volume on the absolute and relative forest density is a closely correlated value being reliable at a hig

Abstract:

Abstract Forest restoration treatments of thinning young trees followed by prescribed burning in north-western Arizona led to significantly lower stand density, lower crown fuel load, and higher crown base height than untreated stands. Simulated fire under extreme weather conditions caused 48 percent more canopy burning and higher flame lengths, heat/area, and rate of spread in untreated stands. Wind speeds required for passive crown fire (torching) were twice as high in treated stands. Treated stands were highly heterogeneous, but restoration treatments clearly enhanced crown-fire resistance.

We developed equations for small trees (2–12 cm diameter) of six species in four young northern hardwood stands. We then compared our equations with equations used frequently in the literature that were developed in mature stands (Whittaker et al. 1974. Ecol. Monogr. 44: 233–252). Our equations f
