Morphometric parameters of pine needles in Tolkuse bog in the dune field in Southwest Estonia

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">Above- and belowground biomass and net primary production (<italic>P</italic>n) of a maturing Norway spruce (<italic>Picea abies</italic> (L.) Karst.) forest (80 years old) established on brown soil in central Estonia were 227, 50 and 19.3 Mg ha correspondingly. Stand structure is determined mostly by mean height and stand density, used widely in forestry, but both are difficult to measure with high precision in respect of canopy processes in individual trees. However, trunk form quotient (<italic>q</italic>2) and proportion of living crown in relation to tree height are useful parameters allowing describe stand structure tree by tree. Based on 7 model trees, leaf unit mass assimilation activity and total biomass respiration per unit mass were determined graphically as mean values for the whole tree growth during 80 years of age. There are still several possible approaches not used carefully enough to integrate experimental work at instrumented towers with actual forestry measurement. Dependence of physiological characteristics on individual tree parameters is the missing link between canopy processes and forest management.</abstract>

The influence of seed origin on stand variables of Scots pine (<italic>Pinus sylvestris</italic> L.) provenance trial in Ahunapalu

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">In the wake of severe climatic extremes during recent years, several new invasive foliage fungi of pines have been reported in Estonia. In this paper the peculiarities of the fast dissemination process, particularly from south to north of two quarantined species, <italic>Mycosphaerella pini</italic> and <italic>M. dearnessii</italic>, but also of <italic>Diplodia pinea</italic> and <italic>Cyclaneusma minus</italic> on different host species are described. These species were known as destructive pathogens in several countries and continents. By today, the range of <italic>M. pini</italic> has already reached northern Finland. In its dissemination process we could follow, with the half-year steps, colonization of Estonia from south to north. Some micromorphological features of these alien species were investigated. Hypothetical risk for pine forests was shortly introduced.</abstract>

Forestry Studies

 Forestry Studies | Metsanduslikud Uurimused is a peer-reviewed journal managed by the Institute of Forestry and Rural Engineering, Estonian University of Life Sciences. The journal publishes original research articles, reviews, technical reports and short communications. Papers are published in English or Estonian with English summary. Authors whose mother tongue is not English are strongly urged to have their manuscripts reviewed linguistically before submission. Submission of an article is understood to imply that the article is original and is not being considered for publication elsewhere. Manuscripts generally should not exceed 25 one-sided 1.5-spaced printed pages, including tables, illustrations, references and abstract. Reviews must not exceed 20 pages, technical reports 5 pages. The authors should aim to submit their work as concisely as possible and longer papers will be accepted under exceptional circumstances. Suitable manuscripts are considered by at least two independent referees before acceptance.   Why subscribe and read   the journal publishes research papers on all aspects of forestry (silviculture, dendrology, tree physiology and genetics, forest products, forest operation and techniques, forest economics and policy, etc.), and also close subjects (environmental protection, ecology, botany, zoology, entomology, pathology, soil science, etc.),  the journal is published twice a year in paper and electronic versions,  peer reviewed journal by experts from Europe and US,  publishing history since 1939.   Why submit   submissions accepted in a wide range of categories: original research articles, reviews, technical reports and short communications,  rapid review (by two independent referees) and fast editing process,  coverage by major abstracting and indexing services,  publishing without charge,  accessibility through MetaPress platform.   Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.  Plagiarism Policy  The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
