Accessibility of urban green space, as an important index of evaluating the service level of urban green space, not only shows the resident`s access to green space, but also reflects the environment quality of urban living. Since the quantity, area and space distribution of the patches in urban green space directly affect the function of urban green space and the quality of urban environment, the research on the accessibility of urban green space holds great significance to improve the service of urban green space and the living environment quality. Based on GIS software, this research uses the road network and the population distribution data of Nanjing`s city proper to conduct quantitative analysis of the accessibility of park green space and the convenience for residents to travel under different forms of transportation. After the case analysis, the author tests the application of road network in studying the accessibility of urban park green space and proposes a GIS-based method to study the accessibility and the rational layout of urban green space.

This study was carried out in the Boin and Miryousef regions in Baneh of Kordestan province, west of Iran. Both areas were divided into two parts including protected and unprotected areas. In each area, 20
circular plots were established following a selective method. Tree and shrub species were identified and the number of these species was counted in each sampling plot. The results indicated that 7 trees, 4 shrubs and 109 herbaceous species were found in the studied areas, 40 herbaceous, 7 tree and 3 shrub species were present in protected area, while unprotected area had 16 herbaceous and 3 tree species. The highest value of diversity indices belonged to protected areas in all vegetation layers. In tree layer, Quercus brantii had the greatest value of SIV, whereas the lowest value belonged to Pistacia atlantica. In shrub layer, the highest and lowest values of SIV belonged to Daphne mezereum and Cerasus microcarpa, respectively. Finally, in herbaceous layer, Luzula spicata had highest value of SIV, and lowest value was belonged to Galium sp.

DTPA (Diethelene-triamine pentaacetic acid) extractable micronutrients of surface soil samples from six different locations of Cox`s Bazar and Chittagong districts were studied. All the soils under study were sufficient in DTPA extractable Fe, Mn and Cu contents. The available Zn contents in soils of Dulhazara, Chengchhari and Faissakhali under study were also above the critical limit while soils at Fulchhari, Hasnabad and CU were deficient in available Zn. The study also showed that DTPA extractable Fe content had the significant and positive relationships with clay and soil organic carbon. On the hand, negative and significant relationship was observed between extractable Mn and soil pH while DTPA extractable Zn and Cu were positively and significantly correlated with soil organic carbon of the studied area.

A total of 680 angiosperm plant species under 433 genera of 115 families have been recorded from the Southeast offshore Islands of Bangladesh including Nijhum Dwip, Hatiya, Sandwip, Kutubdia, Maheshkhali, Sonadia and Saint Martin`s. Magnoliopsida is represented by 92 families, 344 genera and 546 species, whereas Liliopsida is represented by 23 families, 89 genera and 134 species. Habit analysis shows that herbs, shrubs, trees and climbers were represented by 331, 117, 169 and 63 species respectively. The plant diversity of the southeast offshore islands is under great risk because of many threats including natural and manmade. The aims of the present study are investigation, accumulation and documentation of the angiosperm plants of the area.

Lynser, Marvellous B. ; Tiwari, Brajesh Kumar ;
Journal of Forest and Environmental Science , volume 32, issue 1, 2016, Pages 39~54
DOI : 10.7747/JFES.2016.32.1.39
The present study analyzes the diversity and usage of NTFPs and evaluates their importance in the day to day life of the people of rural Meghalaya. People use 172 NTFPs belonging to 139 plant species mainly for food, medicine and fuelwood and to a lesser extent for construction, handicrafts and ornamental purpose. These 139 plants belonged to 117 genera and 70 families with Rosaceae, Poaceae and Fagaceae families as the dominant NTFP yielding families. Fruits from shrubs and trees are most commonly harvested by people. Collection and availability of NTFPs for use as food are more during the summer season, which is also the period with least availability of job. NTFPs for subsistence use are greater in number than those having commercial value. The most commonly harvested plant parts are fruits and leaves. Roots, rhizomes and whole plants are extracted in lesser quantity which is a positive approach from sustainability point of view. NTFPs and other forest products also form a vital part of the rural household`s income generation activities.
Deforestation and Forest land Use in Côte d`Ivoire: Policy and Fiscal Instruments
Djezou, Wadjamsse Beaudelaire ;
Journal of Forest and Environmental Science , volume 32, issue 1, 2016, Pages 55~67
DOI : 10.7747/JFES.2016.32.1.55
This paper investigated policies that drive the sustainable management of Ivorian forest which disappear at an annual rate of 250000 hectares. Based on an inter-temporal model for optimum allocation of forest land to three competing uses, the article found that sustainability depends on the incentive structure, of which forest taxes and fees are a key, though obviously not the sole, component. The study proposed to increase the area fee level by accounting for environmental externalities generated by forest harvesters and farmers. The paper showed that the area fee is a decreasing function of the forest natural rate of regeneration and the reconversion rate of agricultural surfaces. Finally, at the given forest natural rate of regeneration and the reconversion rate of agricultural surfaces, the model argued that the area fee need to be progressive (arithmetic progression) in the context of ecological equilibrium break while it should remain constant in normal situation.

We investigated structure and intensity of 267 echolocation calls that were collected from the five Korean Myotis species (M. nettereri, M. petax, M. ikonnikovi, M. macrodactylus and M. formosus). All the Myotis species produced typical FM call pattern with similar echolocation call shapes and outer shapes, producing steep, downward frequency-modulated calls. A pulse has two harmonies, which consist of the first harmony with wider bandwidth and the second harmony with narrower bandwidth. The PF of the first harmony is higher than that of the second harmony. The typical FM call structure, with two harmonies and wide bandwidth, might be highly related to fast flying and wide screening in the dense forests. In classification of the echolocation calls by DFA, most of calls from the five species could be well correctly classified. All calls of M. nettereri (100% of 17 calls), M. formosus (95.5% of 22 calls) and M. ikonnikovi (85.7% of 70 calls) could be well discriminated from those of the other species, whereas calls of M. petax and M. macrodactylus could be discriminated by 70.4% of 98 calls and 76.7% of 60 calls, respectively. Our results indicate that the five Korean Myotis species can be well identified by the echolocation calls with high correct classification by DFA.

Classified into sub-tree of the growth-form, Acer pseudosieboldianum and Carpinus cordata hardly reach the uppermost canopy with limited height growth potentiality in the natural deciduous forest. However, the two species usually dominate lower stories of the forest, playing an important role in overall ecological characteristics in the forest. Based on the vegetation data of 106
sample plots in Mt. Jumbong area, this study was carried out to evaluate ecological constitution by several quantitative analysis so as to understand the mechanism of the natural deciduous forest. The results indicated that individuals of A. pseudosieboldianum and C. cordata were absent or few in overstory, but emerged the most dominant species in midstory and understory, providing adequate proof of the ecological importance. The comparison of indices of succession between presented and predicted values in midstory did not make much difference, suggesting that the species composition would not change much and come close to steady state in midstory and understory. The pair combination of species association noted that A. pseudosieboldianum had significant positive association with C. cordata, Quercus mongolica, and Tilia amurensis had significant positive association with A. pseudosieboldianum, A. pictum subsp. mono and Fraxinus mandshurica but negative association with F. rhynchophylla. Being compared with other major canopy tree species in the study forest, the target species of A. pseudosieboldianum and C. cordata had strong regeneration strategies, partially characterized by large number of saplings and pole sized trees and high ratio of live crown, which indicated high shade tolerance to survive in the limited amount of light under the canopy. Even though A. pseudosieboldianum and C. cordata do not reach and occupy the canopy layer mainly due to the inherent growth form, they would have highest competitive potentiality to prosper and dominate in the midstory of the natural deciduous forest.
Native Customary Rights: Does It Hold the Future of Sarawak`s Natives?
Nelson, Julia ; Muhammed, Nur ; Rashid, Rosmalina Abdul ;

This article presents an overview of the Native Customary Rights to forests and its role in protecting the future of native people of Sarawak, Malaysia. The native people have had a long history and strong relationship with their forests. Existing documents and studies have been critically reviewed and analyzed in order to elaborate the Native Customary Rights which are critical to the native people of this region. To have a better understanding on Native Customary Rights, it is important to answer three related questions: (i) Who is a native of Sarawak, (ii) What is `custom`, and (iii) What is the nature of `rights`? The roles of Native Customary Rights for economic, political or social reasons, operate through informal rules embedded in the natives` customs and traditions. These rules have never been codified into formal laws because the adat system merely functions to manage the human relations which are tied to culture thus making it difficult to codify the culture into laws. It is evident that there are several issues underlying the development of Native Customary Rights: (i) Native Customary Rights are considered as inferiority to those of the State, (ii) the issue of over-shadowing of traditional laws by the colonial rule and the current statutory laws and, (iii) projects and land schemes involving the Native Land. It is understood that the challenges of promoting Native Customary Rights are daunting task; however, the constitutional laws need to carefully revise to provide a better future for the natives.

Calamus andamanicus Kurz is one of the commercially important solitary rattans endemic to Andaman and Nicobar islands. The habitat suitability modeling program, MaxEnt, was used to predict the potential ecological niches of this species, based on bioclimatic variables. The study revealed high potential distribution of C. andamanicus across both Andaman and Nicobar islands. Of the 33 spatially unique points, 21 points were recorded from South and North Andamans and 12 from Great Nicobar Islands. The islands like Little Andaman, North Sentinel, Little Nicobar, Tllangchong, Teressa were also predicted positive even though this rattan is not recorded from these islands. Mean diurnal range, higher precipitation in the wettest month of the year, annual precipitation and precipitation in the driest month are the main predictors of this species distribution.

Echolocation call structure and intensity were measured from the Malaysian Myotis muricola, which were recorded from the hand-released bat. The Malaysian M. muricola produced typical FM call pattern of the genus Myotis, producing steep, downward frequency-modulated calls. The average PF of calls is
. Discrete PF patterns of two types are found, which consist of 63.39 kHz and 66.15 kHz. The averages of SF and D are
, respectively. There are various IPI lengths with average of
. A pulse consists of two harmonies which consist of the first harmony with wider bandwidth and the second harmony with narrower bandwidth. The PF of the first harmony is higher than that of the second harmony. The typical FM call structure, with two harmonies and wide bandwidth, would be highly related to fast flying and wide screening in the dense forests.
