Besiq Bermai Forest is part of Kalimantan forests known for vast plant diversity. The present study aimed to investigate flora diversity, composition, and ecology in Besiq Bermai Forest to support the management of biodiversity and forest conservation. Thirteen plots were established with different sizes of plots (100 m x 20 m plots for trees; 40 m x 5 m plots for saplings; and 5 m x 5 m plots for understory). Data recorded included plant species name and individual number of each plant species. Data analysed were Shannon-Wiener diversity index, Relative Density, Relative Frequency, Relative Dominance and Important Value Index. The principal component analysis (PCA) was performed to determine relationship between edaphic components and flora occurrence. The results showed that there were 93 species of trees (belonging to 48 genera and 22 families), 112 species of saplings (belonging to 62 genera and 43 families), and 48 species of understory (belonging to 28 genera and 20 families). Shannon-Wiener diversity index (H') were 6.05, 6.25 and 3.26 for tree, saplings and understory, respectively. The most common family for tree and saplings in the forest ecosystem in this area was Dipterocarpaceae (Shorea spp). Species of tree with the highest importance value index were Dillenia excelsa, Syzygium sp. and Shorea parvifolia. The highest importance value index for species of saplings were Macaranga triloba and Shorea parvifolia; and for species of understory were Phrynium jagorianum. Ecological (edaphic) factors affecting the occurence and establishment of flora in Bermai forest were total N and C/N ratio. The present study has implication for the management of biodiversity and forest conservation.

“…State is the current status, or condition, of abiotic (e.g., water, air and soil) or biotic features (e.g., genetic diversity). Benefits describe the various services that are provided by biodiversity to humans and ecosystems (see MEA 2005, Malouin et al 2016. Responses are policies or actions to address changes in pressures, state and benefits to prevent or reduce negative effects on forest ecosystems.…”

The NEBIE plot network is a stand-scale, multi-agency research project designed to compare the ecological effects of a range of silvicultural treatments in northern temperate and boreal forest regions of Ontario, Canada. While research on silviculture intensities has been previously conducted, the NEBIE plot network is at a larger scale, and covers a wider range of intensities in a variety of northern temperate and boreal forest types. Details about experimental design, treatment designs and research sites, are presented in a companion paper which is published in this edition of The Forestry Chronicle. The operational scale of treatment plots allow for assessment of a variety of forest values. We used a criteria and indicator approach to organize long-term research studies on the network sites, with the goal of providing scientific findings that would inform forest policy. Pre-treatment, and 2-, 5-, and 10-year post-harvesting data have been collected. These initial data add to existing information on the effects of intensification of silviculture on biological diversity, forest productivity, ecosystem health and vitality, soil and water resources, contribution of enhanced forest management global carbon cycles, and long-term multiple socio-economic benefits of northern forests.Keywords: ecosystem services, forest research, silviculture, sustainable forest management RÉSUMÉ Le réseau de placettes NEBIE est un projet de recherche à l' échelle du peuplement regroupant plusieurs organismes et destiné à comparer les effets écologiques d'une gamme d'interventions sylvicoles dans les régions tempérée et boréale en Ontario au Canada. Même s'il y a déjà eu des travaux de recherche sur l'intensification de la sylviculture, le réseau de placettes NEBIE se situe à une bien plus grande échelle et se prête ainsi à expérimenter une plus vaste gamme d'intensités dans une variété de conditions dans les forêts tempérées et boréales. On trouvera plus de renseignements sur le plan expé-rimental, les traitements et les sites expérimentaux dans un autre article de ce numéro du The Forestry Chronicle. Le fait qu' on dispose de placettes à l' échelle opérationnelle permet d' évaluer une variété de valeurs forestières en même temps. Nous avons adopté une approche par critères et indicateurs pour disposer les sites expérimentaux à long terme sur les différentes stations du réseau en vue d' obtenir des résultats scientifiques qui puissent apporter des éclairages pour guider la politique forestière. On dispose maintenant de mesures prises avant les traitements puis 2, 5 et 10 ans après la récolte. Ces données de départ s'ajoutent à la documentation portant sur les effets de la sylviculture intensive sur la biodiversité, la productivité forestière, la santé et la vitalité des écosystèmes, les sols et les ressources en eau, la contribution de l'aménage-ment bonifié sur les cycles planétaires du carbone et les nombreux bienfaits socioéconomiques à long terme liés aux forêts nordiques.

“…Global competition and societal change are eliciting incremental changes within the Canadian forest sector (sensu [1]). Forest management objectives and associated inputs are increasingly focused on enhancing end-product quality and value [2] and providing a wider array of ecosystem services (e.g., provisionary, regulatory, and cultural services [3]) while maintaining or increasing volumetric fibre yields. Realizing this aspirational trivariate goal will be partially dependent on the provision of enhanced operational intelligence and associated decision-making capacities in relation to the management and optimization of end-product flows within the upstream portion of the forest products supply chain.…”

The objective of this study was to specify, parameterize, and evaluate an acoustic-based inferential framework for estimating commercially-relevant wood attributes within standing jack pine (Pinus banksiana Lamb) trees. The analytical framework consisted of a suite of models for predicting the dynamic modulus of elasticity (m e ), microfibril angle (m a ), oven-dried wood density (w d ), tracheid wall thickness (w t ), radial and tangential tracheid diameters (d r and d t , respectively), fibre coarseness (c o ), and specific surface area (s a ), from dilatational stress wave velocity (v d ). Data acquisition consisted of (1) in-forest collection of acoustic velocity measurements on 61 sample trees situated within 10 variable-sized plots that were established in four mature jack pine stands situated in boreal Canada followed by the removal of breast-height cross-sectional disk samples, and (2) given (1), in-laboratory extraction of radial-based transverse xylem samples from the 61 disks and subsequent attribute determination via Silviscan-3. Statistically, attribute-specific acoustic prediction models were specified, parameterized, and, subsequently, evaluated on their goodness-of-fit, lack-of-fit, and predictive ability. The results indicated that significant (p ≤ 0.05) and unbiased relationships could be established for all attributes but d t . The models explained 71%, 66%, 61%, 42%, 30%, 19%, and 13% of the variation in m e , w t , s a , c o , w d , m a , and d r , respectively. Simulated model performance when deploying an acoustic-based wood density estimate indicated that the expected magnitude of the error arising from predicting d t , c o , s a , w t , m e, and m a prediction would be in the order of ±8%, ±12%, ±12%, ±13%, ±20%, and ±39% of their true values, respectively. Assessment of the utility of predicting the prerequisite w d estimate using micro-drill resistance measures revealed that the amplitude-based w d estimate was inconsequentially more precise than that obtained from v d (≈ <2%). A discourse regarding the potential utility and limitations of the acoustic-based computational suite for forecasting jack pine end-product potential was also articulated. Keywords: wood quality; dilatational stress wave velocity; absolute and relative error intervals; ResistographForests 2019, 10, 605 2 of 29 however, a priori knowledge of the internal fibre attributes, which are among the principal determinates underlying end-product quality (sensu [4]), are not readily observable or measurable within standing trees prior to harvest nor within the derived logs following harvest. Furthermore, forecasting end-product potential based on correlative relationships between external morphological tree characteristics and internal fibre attributes have yielded mixed results of generally limited utility [5]. Thus, apart from the implementation of a logistically-challenging destructive-based field sampling initiative combined with the subsequent expensive and time-consuming laboratory processing of extracted wood samples...
