Silver fir is one of the longest living and tallest trees in Europe, it has major commercial importance and may be found in various communities predominantly connected with lower mountainous locations...
Allometric Biomass Models for European Beech and Silver Fir: Testing Approaches to Minimize the Demand for Site-Specific Biomass Observations
biomass Romania site-specific Fagus sylvatica Abies alba Bayesian model mixed effect models
2023/12/11
In this paper, site-specific allometric biomass models were developed for European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) to estimate the aboveground biomass in inca virgin?fores...
Shifts in Foliage Biomass and Its Vertical Distribution in Response to Operational Nitrogen Fertilization of Douglas-Fir in Western Oregon
Douglas-fir nitrogen fertilization foliage distribution allometry biomass
2024/2/4
Nitrogen (N) fertilization is a commonly applied silvicultural treatment in intensively managed coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantations. Field trials were e...
Modeling the Carbon Cycle of a Subtropical Chinese Fir Plantation Using a Multi-Source Data Fusion Approach
process-based terrestrial ecosystem model model–data fusion multi-source data carbon cycle plantation
2024/2/5
Process-based terrestrial ecosystem models are increasingly being used to predict carbon (C) cycling in forest ecosystems. Given the complexity of ecosystems, these models inevitably have certain defi...

The article aims to evaluate the research provenance plot established in 1980 in locality No. 214 – Hrubá Skála (in the north of the Czech Republic), where nine provenances of grand fir (Abies grandis...
Root system development in naturally regenerated Douglas-fir saplings as influenced by canopy closure and crowding
natural regeneration competition shading physical tree stability
2015/9/15
Documented information on the growth dynamics and related silvicultural manipulation of naturally
regenerat ed Douglas-fir beneath a canopy shelter is scarce. We hypothesized that long regeneration ...
Does prolonged stratification of Douglas fir influence the yield of seedlings?
