The journal is using Editorial Manager System for quality in review process. Editorial Manager is an online manuscript submission, review and tracking systems. Review processing is performed by the editorial board members of Journal of Biodiversity Management & Forestry or outside experts; at least two independent reviewers approval followed by editor approval is required for acceptance of any citable manuscript. Authors may submit manuscripts and track their progress through the system, hopefully to publication. Reviewers can download manuscripts and submit their opinions to the editor. Editors can manage the whole submission/review/revise/publish process.
Journal of Biodiversity Management & Forestry is organizing & supporting 3rd International Conference on Biodiversity & Sustainable Energy Development during June 24-26, 2014 in Valencia Conference Centre, Spain with the theme of Milestones of innovative scientific research in biodiversity and its allied areas.
Growth and Survival of Pinus Seedlings as Influenced by Different Mycorrhizae and Ordinary Soil Ratios in a Nursery
A study was conducted to determine the effect of different mycorrhizae and ordinary soil ratios on height growth, root collar diameter growth, survival and root colonisation of pinus seedlings in a nursery for sixteen weeks. Seedlings were subjected to six different mycorrhizae to ordinary soil ratios treatments which were completely randomised in four replicates, namely: 1:0, 1:1, 1:5, 1:10, 1:20 and 0:1(100% ordinary soil) as a control. The results indicate that there was a significant difference on the mean height growth, root collar diameter, survival rate and root colonisation of the seedlings. The treatment of soil ratio of 1:0 (mycorrhizae to ordinary soils) had the highest mean height, root collar diameter, survival rate and root colonisation than the other treatments. These means that height, root collar diameter, survival rate and root colonisation of seedlings decreased with an increase of ordinary soils. Therefore, mycorrhizae soils are essential in the raising of pinus seedlings in the nursery and where pinus plantations are well established, the treatment ratio of 1:0 (100% mycorrhizae soils) is recommended for inoculating pinus seedlings at the nursery.
A Mixed-effects Height-Diameter Model for Pinus kesiya in Malawi
A height-diameter model was developed in order to predict the total height of individual trees in Pinus kesiya in Malawi. Six generalized height-diameter models were fitted and evaluated based on dataset consisting of 18156 tree heights and corresponding diameters at breast height. The data were collected during three inventories of 332 permanent plots located in Chongoni, Malawi. A model including the diameter at breast height of the tree, stand age, site index, and basal area as independent variables was selected as the best model. To deal with the problem of among-unit variability, a non-linear mixed effects modelling approach was used to fit the selected model. The mixed model included a random parameter that affected the model and provided realistic height predictions. The equation developed represents a new tool for evaluation and management of Pinus kesiya stands in the region.
Sacred Groves of Arunachal Pradesh: Traditional Way of Biodiversity Conservation in Eastern Himalaya of India
Due to its varied edaphic, climatic and geographic conditions, India is blessed with a rich biodiversity. Sacred groves form a significant part of the India’s floral and faunal diversity and are found in many parts of the country particularly where indigenous communities live for centuries. They act as an ideal centre for ecosystem services generation due to their varied and rich biodiversity. The sacredness, religious culture, beliefs and taboos play a significant role in promoting conservation and sustainable utilization of biodiversity of the region where sacred groves are found. Due to the materialistic culture of the society during recent years, considerable changes have taken place in people’s attitudes towards these centers of biodiversity conservation. The current paper highlights current status of some of the significant sacred groves located in Arunachal Pradesh state of India. Ways to protect and preserve these
biodiversity assets have been discussed in the paper.
Mangrove Species Diversity of Sandwip Island of Chittagong, Bangladesh
The present study deals with the diversity of mangrove plant species of Sandwip Island of Chittagong, Bangladesh. A total of 18 mangrove plant species under 15 genera and 12 families have been documented from the study area. The species diversity has been investigated by random quadrat method. Shannon-Wiener diversity index (H`), species richness (d) and Pielou’s evenness index (J`) have been analysed by using PRIMER v6 program. Highly dominant species of the area are Excoecaria agallocha L., Zoysia matrella (L.) Merr., Sonneratia apetala Buch.-Ham. and Tamarix indica Willd. It can be concluded that the present study will be helpful for the planners and policy makers to plan for the better conservation and sustainable management of mangrove plant resources of Sandwip Island as well as to prepare a useful green belt to protect the coastal area..
