Juri is a biodiversity-rich primary forest in Bangladesh, which remains ecologically unexplored. We identified tree species and examined the richness, alpha (α) diversity and floristic similarity patterns within the identified communities. Vegetation and environmental data were sampled in 120 (0.04 ha) study plots. Tree communities were delimited b...

Leaf area (A0) and leaf biomass (M0) estimation are significant prerequisites to studying tree physiological processes and modeling in the forest ecosystem. The objective of this study was to develop allometric models for estimating A0 and M0 of Swietenia mahagoni L. from different tree parameters such as DBH and tree height of mahogany plantations...

The seed germination of seed sources and pre-sowing treatments of Acacia catechu and Elaeocarpus floribundus seeds was conducted in the nursery of Bangladesh Agricultural University. The seeds were collected from 15 to 25 years old matured and healthy trees from four different locations in Bangladesh and treated with six pre-sowing methods (Control...

The diameter and height distribution of the growing stock is an essential starting point in many forest management planning problems. There are several methods for predicting the diameter and height distribution of a stand, varying from methods which utilize theoretical distribution functions to non-parametric methods. Data from 160 plots, establis...

The diversity-productivity relationship has received considerable attention during the past two decades, largely because of the continuous loss of biodiversity. The positive relationship between species diversity and productivity is significant as a credible argument for the conservation of biodiversity. This research was conducted in the central r...

The seed germination of pre-sowing treatments of Aquilaria agallocha and Shorea robusta seeds was conducted in the nursery of Bangladesh Agricultural University. The seeds were collected from 18 to 26 years old matured and healthy trees from various locations in Bangladesh and subjected to different pre-sowing treatments, i.e. control, soaking in n...

This research was conducted at the Agroforestry Research Farm, Hajee Mohammad Danesh Science and Technology University to quantify the effects of pruning height in Jatropha curcas L. (Jatropha) and fertility levels of the recommended dose of NPK in Glycine max L. (Soybean) on crop growth parameters and yield in the agrisilviculture system of Agrofo...

Abstract Madhupur National Park is renowned for severe resource ownership conflicts between ethnic communities and government authorities in Bangladesh. In this study, we applied the Institutional Analysis and Development framework to identify: (i) past and present informal institutional structures within the ethnic Garo community for land resource...

Non-timber forest products (NTFPs) play significant roles in the livelihoods of forest dependent community and forest conservation. It also plays a key function in forest management for most tropical countries. This study is conducted in the Habiganj-2 forest range in the north-eastern region of Bangladesh purposely based on a semi structured quest...

Leaf area and leaf biomass have an important influence on the exchange of energy, light interception, carbon cycling, plant growth and forest productivity. This study showed development and comparison of models for predicting leaf area and leaf biomass of Lagerstroemia speciosa on the basis of diameter at breast height and tree height as predictors...

Estimation of leaf area (LA) and leaf biomass (LB) is important to understand plant physiological and carbon assimilation processes, and tree growth models. The aim of this study was to develop and compare allometric equations for predicting LA and LB of Artocarpus chaplasha Roxb. taking diameter at breast height (DBH) and tree height as predictors...
