Pest categorisation of Cephalcia lariciphila

EFSA Journal, 2017
The Panel on Plant health performed a pest categorisation of the larch web‐spinning sawfly Cephalcia lariciphila (Hymenoptera: Pamphiliidae) for the EU. The insect has been reported in 11 EU Member States (MSs).

National growth models for stand basal area, volume, and biomass in Chinese larch plantations: integrating stand structure and species effects

Trees, Forests and People
Forest growth and yield models are essential tools for forest management decision-making, but most models have neglected the inclusion of stand structure. The relationship between stand structure and stand growth has been widely reported, but the results

Regeneration Process of Broadleaved Trees in Planted Larix kaempferi Forests.

Journal of the Japanese Forest Society, 2006
北海道石狩低地帯南部の41～51年生のカラマツ人工林において, 林内への広葉樹の侵入過程を明らかにするため, 施業履歴, 林分構造, 広葉樹の樹種構成, 樹齢, 埋土種子の種組成を調べた。広葉樹の密度は, 林床にササが優占する林分で小さく, ササ類は広葉樹の更新に負の影響を与えていると考えられた。広葉樹の更新個体数は, 間伐後に増加する傾向が顕著であり, 間伐は広葉樹の更新契機になっていると考えられた。また広葉樹の樹種数は, 間伐にともなって階段的に増加しており, 特にギャップ種は, 初回の間伐以降に樹種数が増加していた。埋土種子の種構成は, 広葉樹の樹種構成とは類似しておらず, カラマツ人工林内での広葉樹類の更新には, 種子バンクの寄与は小さいと推察されたが ...

Soil N and P nutrient metabolism affected by fungal community in larch plantation

Frontiers in Microbiology
IntroductionThe time-response mechanism of soil nitrogen (N) and phosphorus (P) nutrients across different stand ages remains intricate and inadequately quantified, particularly unclear is the effects of rhizosphere soil microbial communities, which ...

Advancing Stem Volume Estimation Using Multi-Platform LiDAR and Taper Model Integration for Precision Forestry

Remote Sensing
Stem volume is a critical factor in managing and evaluating forest resources. At present, stem volume is commonly estimated indirectly by constructing a taper model that utilizes sampling, diameter at breast height (DBH), and tree height.

Nonlinear mixed effects height to crown base model for Larix kaempferi plantation in China by considering initial planting density and thinning intensity

Frontiers in Forests and Global Change
Height to crown base is a main component of crown structure to understand the growth of the tree. It is essentially important to construct a comprehensive height to crown base model to facilitate the application in forest management practice decision ...
