Abstract Key message We studied size distributions of decay-affected Norway spruce trees using cut-to-length harvester data. The data comprised tree-level decay and severity recordings from 101 final felling stands, which enabled to analyze relationships between all trees. Distribution matching technique was used transfer the distribution into diameter at breast height (DBH) Context Stem ( Pice...

A procedure is described for incorporating stand age, or stage in development, into the widely used stocking guides based on the crown competition factor (CCF). A simple model that predicts dbh of individual trees from crown projection area and total height is derived from a three-dimensional relationship between cumulative foliage production (crown volume) and total volume of the main stem. Pr...

elm (ulmus glabra hudson) is one of the most valuable species which distribute all over the caspian forests. nowadays, elm is considered an endangered species due to intensive human activities and outbreak of dutch elm disease over the last few decades. to suitable management of elm, there is need to have indices which describe; current structure and its changes across the time. this study besi...

Any defects in street trees may cause injuries to human, vehicles and buildings. This research was investigated in the Babol city, Mazandaran province, in the northern state of Iran.Used the perfect inventory methods and measured the diameter at breathe height (DBH), height and hazardous criteria (dead woods, cracks or seams, decay, wound or cankers, root problems, weak branch unions and skew f...

There is limited information about the precise quantification Aboveground Biomass (AGB) species-specific allometric equations shrubs and small trees. Thirty plants were selected to develop equation...

Forest aboveground biomass (AGB) plays an important role in regulating the global carbon cycle and is thus essential component of ecosystem functioning. In relationships between biodiversity functioning (BEF), studies have shown that many biotic factors (e.g., species, functional traits, large trees) abiotic significant impacts on AGB. However, relative strength these affecting remains unclear....

This study evaluated balsa wood (Ochroma pyramidale) plantations in the search for matrices genetic improvement. We were a total of 20 trees Mato Grosso diversity with ISSR (Inter Simple Sequence Repeats) primers, as well their diameter at breast height (DBH) and commercial (CH). The primers amplified 111 loci (97.3% polymorphic), Nei (0.32) Shannon index (0.48) indicate that there is plantatio...

The main objective of this research was to evaluate the use unmanned aerial vehicles (UAVs) in estimating aboveground biomass and carbon, dasometric characteristics at three different spacings (2.5 m × 1.0 m, 2.5 2.0 3.0 m) a silvopastoral system (SPS) for production Tectona grandis. A total 90 trees were sampled, 63 which used perform evaluation (vertical horizontal) spacing test an SPS, rest ...

The application of static terrestrial laser scanning (TLS) in forest inventories is becoming more effective. Nevertheless, the occlusion effect is still limiting the processing efficiency to extract forest attributes. The use of a mobile laser scanner (MLS) would reduce this occlusion. In this study, we assessed and compared a hand-held mobile laser scanner (HMLS) with two TLS approaches (singl...
