BACKGROUND REDD+ programs rely on accurate forest carbon monitoring. Several REDD+ projects have recently shown that local communities can monitor above ground biomass as well as external professionals, but at lower costs. However, the precision and accuracy of carbon monitoring conducted by local communities have rarely been assessed in the tropics. The aim of this study was to investigate dif...

The aim of this study was to evaluate Eucalyptus badjensis concerning the genetic variation for growth traits and the potential of the species in supporting a breeding programme. The field trial was a provenance/progeny test established in Campina da Alegria, Santa Catarina, Brazil (latitude 26°52'05.1″ S, longitude 51°48'47.5″ W, altitude 1,015 m) in a soil classified as Latossolic Alumino-Fer...

The ambrosia beetle, Platypus koryoensis (Murayama), vectors the Korean oak wilt (KOW) pathogen, Raffaelea quercus-mongolicae K.H. Kim, Y.J. Choi, & H.D. Shin, in Korea, which is highly lethal to Mongolian oak, Quercus mongolica Fisch., and is considered a major threat to forest ecosystem health. We characterized the attack pattern of P. koryoensis along the lower trunk of 240 Mongolian oaks i...

Abstract The aim of this study was to model the height and diameter distributions height-diameter relationship in an old unmanaged Eucalyptus stand southeastern Brazil. at 1.30 m above soil (DBH) total (H) all 469 trees were measured. For DBH-H modeling, besides testing various traditional linear nonlinear models, inclusion class as random effect also testes. DBH H seven probability density fun...

In recent years, LIght Detection And Ranging (LiDAR) and especially Terrestrial Laser Scanning (TLS) systems have shown the potential to revolutionise forest structural characterisation by providing unprecedented 3D data. However, manned Airborne Laser Scanning (ALS) requires costly campaigns and produces relatively low point density, while TLS is labour intense and time demanding. Unmanned Aer...

The diameter at breast height (DBH) of trees and stands is not only a widely used plant functional trait in ecology biodiversity but also one the most fundamental measurements managing forests. However, systematically measuring DBH individual over large areas using conventional ground-based approaches labour-intensive costly. Here, we present an improved area-based approach to estimate plot-lev...

The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...

Dalbergia tonkinensis is being promoted in Vietnam for the future supply of prized wood furniture and chemical extraction. Expansion plantation area requires a reliable source quality seed. This study evaluates field performance progeny from mature mother trees natural forests urban environments. Trials were established Tan Son Doan Hung districts Phu Tho province assessed 3 years later. There ...

Pterocarpus angolensis DC and Bobgunnia madagascariensis (Desv.) J. H. Kirkbr. & Wiersema are two hardwood species found in Miombo woodland. Crown size, being closely related to the photosynthetic capacity of a tree, is an important parameter studies growth individual trees. In this sense, present study aimed morphometric relationships P. B. as resource describe features these species. Data...

Research Highlights: This study advances the effort to accurately estimate biomass of trees in peatlands, which cover 13% Canada’s land surface. Background and Objectives: Trees remove carbon from atmosphere store it as biomass. Terrestrial laser scanning (TLS) has become a useful tool for modelling forest structure estimating above ground (AGB) trees. Allometric equations are often used indivi...
