Abstract

The understorey vascular plant cover and its relations with the overstorey tree species and site properties in young silver birch and hybrid aspen plantations were studied. Understorey vegetation was similar in both plantation types in terms of species richness, diversity, sensitivity to human...

Abstract

Entoleuca mammata [causing Hypoxylon canker (HC)] is one of the most serious pathogens that are colonising Populus species. The area of fast-growing hybrid aspen plantations has remarkably increased in northern Europe because of the high demand for woody biomass, but the prevalence of HC and the...

Abstract

At northern latitudes a rise in atmospheric humidity and precipitation is predicted as a consequence of global climate change. We studied several growth and functional traits of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) in response to elevated atmospheric humidity (on average 7%...

Abstract

This review summarises the knowledge about the ecology, breeding and management of hybrid aspen (Populus × wettsteinii Hämet-Ahti=P. tremula L. × P. tremuloides Michx.). The review is restricted mainly to Northern Europe, where hybrid aspen has been most intensively studied and cultivated and where ...

Abstract

The impact of soil available water content (AWC) on the growth and foliar nutrient concentrations of trees in 7-yr-old hybrid aspen (Populus tremula L. × P. tremuloides Michx.) plantations established on abandoned agricultural lands was studied. AWC in the topmost 75 cm soil layer was significantly ...

Abstract

We studied species richness, composition and coverage of the bryophyte layer in young deciduous forest plantations on abandoned agricultural lands in relation to overstory tree species (hybrid aspen or silver birch), land use history (crop field or grassland), site preparation method (whole-area...

Abstract

This issue contains 10 papers describing the silviculture of deciduous trees in Estonia. Specifically, the topics discussed are: (1) growing broadleaves; (2) deciduous trees in Estonia; (3) economic aspect of afforestation on abandoned agricultural lands; (4) cultivation of oak (Quercus robur) in...

Abstract

Floristic diversity was studied in 7- to 8-year-old commercial hybrid aspen (Populus tremula × Populus tremuloides) plantations on abandoned agricultural sites with a different land use (grassland or crop field) and site preparation (whole-area ploughing or strip tillage) history in Estonia. The...

Abstract

The present paper is based on the study of 21 plantations of deciduous trees growing on abandoned agricultural land in Estonia. For the establishment of the plantations, four fast-growing deciduous tree species (silver birch (Betula pendula), grey alder (Alnus incana), hybrid alder (A. hybrida) and ...
