Effect of gap size on tree species diversity of natural regeneration - case study from Masaryk Training Forest Enterprise Křtiny

Popis výsledku v původním jazyce

Forest gaps remain the optimal forest management practice in modern forestry. Upon all the physical pr-operties of forest gaps, the &apos;gap size&apos; feature stands out as an essential property. The effect of gap size on tree species composition and diversity of natural regeneration in forest gaps of different sizes was investigated. Eight research forest gaps were selected from the Training Forest School Enterprise, also called Masaryk Forest in Křtiny, a temperate mixed forest in the Czech Republic. By given gap sizes, small (&lt; 700 m2) and large gaps (GREATER-THAN OR EQUAL TO 700 m2) were defined. Forty-one (41) regeneration microsites (RSs) of 1 m2 circular area at 2 m intervals were demarcated within each forest gap. These RSs served as data collection points.From the total of eleven (11) species enumerated, large gaps obtained higher species composition (10) and diversity (Simpson = 0.5 1-D; Shannon = 1.0 H and Pielou&apos;s evenness = 0.5 J indices) records, yet, small gaps presented favourable conditions for prolific natural regeneration significantly. Light-adapted species demonstrated no significant difference (P &gt; 0.05) between small and large gaps, however, intermediate and shade-to-lerant species were significantly higher (P &lt; 0.05) in small gaps. There were progressive declines in height growth of natural regeneration from 0-20 cm to 21-50 cm and 51+ cm in small and large gaps at R2 = 99% and 88%, respectively. The development of herbaceous vegetationin small and large gaps had positive and negative effects on the natural regeneration of Fagus sylvatica and Abies alba species, respectively.
