Evaluation of the IUFRO provenance plot with grand fir in the Habr locality (Western Bohemia) at the age of 31 years

Journal of Forest Science, 2015
In the framework of an international IUFRO provenance research of grand fir (Abies grandis/D. Don/ Lindl.), a series of research plots was established in the Czech Republic in 1980-1982. This paper focuses on an evaluation of experimental plot No.

Forest Biomass for Bioenergy production – Comparison of Different Forest Species

Energy Procedia, 2014
AbstractForest biomass is a renewable and sustainable source of energy that can be used for producing electricity, heat, and biofuels. The production of biomass for energy is considered to be an important step in developing sustainable communities and managing greenhouse gas emissions effectively.

Evaluating citizen science data for forecasting species responses to national forest management

Ecology and Evolution, 2017
The extensive spatial and temporal coverage of many citizen science datasets (CSD) makes them appealing for use in species distribution modeling and forecasting. However, a frequent limitation is the inability to validate results.

Open forest successional stages and landscape heterogeneity promote wild bee diversity in temperate forests

Conservation Science and Practice, 2022
Recent studies have emphasized forests as crucial habitat for wild bees. In Europe, most forests are managed following the principles of close‐to‐nature silviculture, which combine timber production and nature conservation.

Microsatellite markers as a useful tool for species identification and assessment of genetic diversity of the Tilia species in the Czech Republic

Czech Journal of Genetics and Plant Breeding
Diagnostic morphological traits distinguishing Tilia cordata and T. platyphyllos are not always apparent. Precise species identification is crucial for conservation management and for establishing genetic resources of forest reproductive material.

Changes in distribution of indigenous forest in Table Mountain National Park from 1880-2012 [PDF]

, 2013
South Africa's indigenous forest only covers 0.56% of the country's total land area. Its highly fragmented distribution and historically extensive exploitation has led it to be perceived as one of the South Africa's most vulnerable vegetation types ...
