Maximum height was assessed for tree species from seven temperate deciduous forests, one subtropical forest and one tropical forest and combined with published tree heights for three other tropical forests. The temperate deciduous forests showed a strong concentration of canopy species and a dearth of subcanopy species. In contrast, the four tropical forests showed more uniform distributions of...

This research had been conducted in the forest area around Gunung Sa-lak Geothermal Power Plant of PT. PLN Indonesia Power. diversity data geothermal power plant yet to be fully available. study aimed analyze composition and structure vegetation conservation Salak unit. used a quadrat plot with purposive sampling method. We sampled 873 individuals from 56 families 110 species, consisting native...

Understanding the structural pattern and regeneration status of tree species is an important measure taken to assess vegetation dynamics their destruction factors as well management history ecology forest. This study was conducted with objective diversity, structure, woody in Kenech natural forest, Ethiopia. Systematic random sampling method employed a design for collection data. Accordingly, 4...

Abstract Key message Different components of water balance and temperature reduce density height growth saplings Picea abies (L.) H. Karst (Norway spruce), Abies alba Mill. (silver fir) Fagus sylvatica L. (European beech) in mixed uneven-aged forests the French Alps Jura mountains. Ungulate browsing is an additional pressure on fir beech that could jeopardise renewal these species future. Conte...

Preliminary results of comparing biologically rehabilitated areas, where three different methods were applied at the same time, to background control showed that sapling planted area greatest similarity (75%) and no difference in vegetation cover biomass (t = -0.88, p 0.40; t -0.22, 0.83) with control. In contrast, hydroseeded was 45.5%, while drill seeded least similar (0%). This suggests plan...

Our modelling approach shows the predominance of facilitative over competition effects in controlling regeneration studied species, thus pointing out to intra- and inter-specific coexistence mechanisms. Natural is a main issue management continental Mediterranean forests. Ensuring natural forest therefore vital for preserving ecosystem function under climate warming increased frequency intensit...
