Climate change knowledge among rural forest adjacent communities influences responsive dynamics towards rural livelihood in terms of mitigations and adaptations. Rural households are highly dependent on natural resources, whose base is highly indisputably threatened by the changing climate. Some of the responses towards climate change dynamics exert increased pressure on Maasai Mau forest resources for sustenance. The aim of this study was to explore the relationship between forest based livelihood dynamics and climate change knowledge. Results indicate that 93% of the respondents were aware of climate change through life experiences. The cited primary causes of climate change by 72% of the respondents included natural causes (26%), human activities (2%) and punishment from gods respectively. The agricultural production and forest products are the main livelihood activities among the people and these livelihood support activities are, to a large extent, affected by climate change. There is need to continuously expose local community to emerging knowledge on impact of climate change for improved mitigation and adaptations.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128447018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Work environment and the performance of forest rangers in South West Mau Forest, Kenya. Asian J For 2: 46-53. The objective of this research was to evaluate and understand how the working environment of Kenya Forest Service (KFS) forest rangers affects their performance. The Rangers, under the Enforcement and Compliance Division (ENCOM) of KFS are mandated to implement the enforcement of laws and policies pertaining to forests and its allied resources as prescribed in the Kenya Forest Act of 2005. Qualitative research approach was employed in the data collection by the use of structured questionnaires in four forest stations. From a population of 46 rangers, 32 rangers, 8 serving in each of the three forest stations {Londiani, Masaita, and Sorget} of Kericho Zone, Mau complex and the Kericho Ecosystem Conservator's Office were sampled randomly. A pre-tested questionnaire on demographic trends, duration of service, work environment variables constituting of remuneration, living conditions, motivation, appraisals, rewards, empowerment, communication, work tools, mobility, uniforms, challenges, and personal life were administered in January 2016. The performance indicators gave dissatisfaction rates of 59% and 63% in most of the parameters tested. Comparison of the finding of this study with the findings of the surveys of 2010 and 2013 in different conservancies in Kenya gave an index of 51.4% and 56.74% satisfaction respectively. The results, therefore, denote a progressive correlation between the working conditions drivers and the performance of forest rangers. Kenya Forest Service under ENCOM Division has a responsibility and large task to improve the working conditions and environment of the rangers. No matter how efficient conservation and regeneration programs may be undertaken while enforcement lags behind the cumulative performance of the entire process shall ever record dismal performance. More radical measures must be undertaken to enhance the performance and productivity of rangers through motivation, improving both their intrinsic and extrinsic working environment. KFS must as well acknowledge that low employee satisfaction rates shall ever incapacitate the forest rangers performance.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131223669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effect of symbiotic association of rhizobia and endomycorrhizae from Moroccan arid littoral dunes on Acacia cyanophylla tolerance to drought. Asian J For 2: 39-45. The research on behavior of A. cyanophylla Lindl plants associated with a symbiotic indigenous endomycorrhizal fungi M, and three rhizobia isolates: two low growing isolate R1 (Bradyrhizobium sp. RCM6), and R2 (Bradyrhizobium sp. RLC3) and a fast-growing isolates R3 (Rhizobium sp. S21), originated from coastal dunes of the Souss-Massa region in drought stress conditions, was investigated in greenhouse. Results have clearly shown that the growth and nutrition of seedlings of A. cyanophylla were drastically affected after two months in drought stress conditions. However, inoculation of the symbiotic microorganisms either alone (treatments M, RMC6, R2 or R3) or as inoculums consisting of combination of the rhizobia with the endomycorrhiza (treatments MR1, MR2 or MR3) resulted in enhanced tolerance of A. cyanophylla seedlings to drought stress. At 100% of field capacity (fc), all treatments showed a significant improvement of plant growth compared to non-inoculated plants in stress conditions. In addition, we have shown that Bradyrhizobium RCM6 (R1) holds a high efficiency to improve the growth and nutrition of the host plant. Indeed, higher number of nodules/plant and higher amount of total nitrogen were recorded in the seedlings inoculated with Bradyrhizobium sp. RCM6 in comparison with plants inoculated with the two other rhizobia Bradyrhizobium sp. RLC3 (R2) and Rhizobium sp. S21 (R3), and control plants. Dual inoculation with each of the three rhizobia and the endomycorrhizal complex (M) led to higher water content (W.C) and relative water content (RWC) and a significant increase in Phosphorus content of the aerial part. While positive effects were recorded for Phosphorus, no such effects were recorded for nitrogen. However, the overall results showed the importance of the use of microorganisms in the dune coastal environment particularly adequate tripartite association: rhizobia Endomycorrhizes-A. cyanophylla in enhancing tolerance to drought stress.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126399230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ice Nucleation Active bacteria in Mount Lawu forest, Indonesia: 3. Isolation and estimation of bacterial populations on bryophyte. Asian J For 2: 67-75. This study aimed to isolate and estimate the Ice Nucleation Active (INA) bacteria population on bryophyte from the trekking route of Cemoro Sewu, Mount Lawu, Indonesia. Bryophyte samples were taken at three different altitudes, i.e., 2,000, 2,300, and 2,500 m above sea level (asl). Isolation of INA bacteria was carried out by the method of spread plate on King's B and nutrient agar plus 2.5% glycerol (NAG) medium. Bryophyte was identified by referring to the literature of Sutama (1995), Hasan and Ariyanti (2004), Ignatova and Samkova (2006), and Damayanti (2006). Ice nucleation activity was determined by the multiple-tube test method. The bacterial suspension tube was put into the circulating alcohol bath at a temperature of -10°C for 5 minutes. The number of INA bacteria on the bryophyte was estimated with the nucleation multiple tube method. The number (cell/g) of INA bacteria from the fresh weight of bryophyte was estimated based on the Most Probable Number (MPN) tables according to the formula of Thomas's 333 series. INA bacteria were identified through morphological and biochemical characters. Independent Sample T-Test analyzed the population of INA bacteria on terrestrial and epiphytes bryophytes with a significance of 5%. The results showed that 7 INA bacteria were isolated from the bryophyte Campylopus umbellatus (Arn.) Paris (Leucobryaceae, Musci). The population of INA bacteria in terrestrial bryophytes at each altitude were greater with 346 cell/g, 86 cell/g, and 396 cell/g, respectively, than that in epiphytes bryophyte with 50 cell/g, 50 cell/g, 176 cell/g, respectively.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122454202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of the India-Myanmar Timber Trade. Asian J For 3: 1-9. Myanmar’s forest cover declined by 1.8% annually between 2000 and 2015: the result of on-going civil wars and institutional weaknesses. As Myanmar transitioned from military dictatorship, round log exports were banned in 2014. Until 2014, India was the most important importer of timber from Myanmar in terms of value, and the second most important in terms of volume, after China. This article assesses the value and volume of timber traded between Myanmar and India from 2010 until 2015. In addition to trade flows, the timber species and main actors involved in the timber trade are identified and the governance environment of trade is assessed. The paper goes on to investigate the impact of recent regulatory changes enacted by the Government of India and the prospects for the future of the India-Myanmar trade. The analysis showed that (i) from an economic perspective the timber trade between the two countries, once active, is currently stalled. (ii) From a governance perspective, illegality occurs to a limited extent at the international border but probably happens to a greater extent at timber auctions in Myanmar. Finally (iii), from a social and environmental point of view, as infrastructure expands it will be crucial to include forest management and timber trade governance in discussions regarding border relations between the two countries.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123386596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Woody biomass and elements uptake in phytoremediation of compost leachate. Asian J For 2: 20-24. This study examined the performance of absorption and growth of Alnus glutinosa and Taxodium distichum which underwent leachate irrigation of Rasht Compost Plant. In mid-March 2013, one year old seedlings of Alnus glutinosa and Taxodium distichum were planted in a greenhouse at Safrabaste Poplar Research Station and since then, this study began. The compost leachate was taken from the collection reservoir of leachate coming from open composting of organic municipal wastes and various gardening and plant wastes. Three treatments were applied to the plants, namely the irrigation using: tap water (control/C), pure leachate (P) and the mixture of one volume unit of leachate with one volume unit of running water (1: 1). It was concluded that leachate had a positive influence on the growth of A. glutinosa and T. distichum namely an increase in diameter and height of seedlings in the measurement period which occured to be caused by fertilization properties of leachate. Statistically, there was no difference in the development of aboveground biomass in the treatment of P, 1: 1 and C. This indicated that both irrigation by pure leachate and mixture liquid stimulate growth in the same way as irrigation by water. The dry mass of root showed the same result as aboveground mass. The total dry mass of the leachate treatment for A. glutinose and T. distichum were, respectively, 83.89 g and 78.68 g. The total root dry mass of leachate treatment for A. glutinosa and T. distichum was, respectively, 11.98 g and 9.09 g. The results of elements absorption showed no statistical difference between the aboveground species. The absorption of Ca concentration in root was higher than the absorption of other elements and showed significant difference in 1: 1 treatment.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126501636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nutrient distribution on soil and aboveground biomass of Macaranga gigantea five years after planting. Asian J For 2: 12-19. The aims of this study were to evaluate growth of M. gigantea and to calculate nutrient distribution in the soil and 5-year-old M. gigantea. Soil sampling was conducted in all research plots with drill ground at a depth of 0-30 cm and 30-60 cm. The tree biomass was sampled within one stand to calculate the biomass of all the trees within a particular plot. The research findings revealed that plot 5 produces the best growth performance and the plant accumulates 2 times of N, P, K, Ca, Mg nutrients on wood, bark, branches, and leaves, compared to the plants in plots 1. The most distributed nutrients in the soil were magnesium, nitrogen, calcium, and phosphorus. Whereas the most accumulated nutrient in plant was potassium. The relative portion of K nutrients accumulates in the soil is quite small that is 44.18% but in stand was higher that is between 55.82%. It concluded that if the M. gigantea harvested at 5 years, it needs to give attention to potassium nutrient for the next of planting cycles.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127830002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant diversity of Betel Leaf Agroforestry of South Meghalaya, Northeast India. Asian J For 2: 1-11. Large areas of lowland tropical forests of South Meghalaya have been converted into betel leaf agroforestry systems by the tribal people living in the area. The betel leaf agroforestry with diverse and structurally complex shade canopies conserve a significant portion of the original forest biodiversity. The impact of land use change on the biodiversity was studied using standard vegetation analysis and biodiversity estimation methods. A total of 160 plant species were recorded in natural forests out of which 75 were trees, 40 shrubs, and 45 herbs, while in betel leaf agroforestry, a total of 159 plant species, 94 trees, 17 shrubs and 48 herbs were recorded. A total of 34 tree species, 13 shrub species, and 14 herb species were common in both the land uses. All the plant species were native species. The study revealed that the conversion of natural forest to betel leaf agroforestry in South Meghalaya has no significant impact on tree and herb diversity. However, the basal area and density are affected to some extent. The land use change has also affected the density and diversity of shrubs. The study concludes that betel leaf agroforestry in South Meghalaya developed by the indigenous War Khasi tribe through experiential learning over several generations has emerged as a fairly sustainable agroforestry system causing minimal impact on plant diversity.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"140 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
