Regeneration of oak (Quercus baloot Griff.) forests is an issue of concern in Khyber Pakhtunkhwa province in general and Sheshikoh Valley of District Chitral in particular. The oak forests cover has been continuously deteriorated and depleted due to uncontrolled grazing, low moisture content of soil, and overusage of the plant as fuelwood and are hence the major contributors toward the failure of oak regeneration. The present study was aimed to asses’ different treatments and their impacts on the growth and regeneration of oak forests. This study was conducted in oak forests of Sheshikoh Valley, Chitral, where four plots of 2-acres each were established. Each plot was treated with separate treatment, that is, fencing, mixed treatment (fencing and fertile soil), fencing and trench treatment, and control plot and their regeneration capacity was studied and compared with each other. The data was collected in March and September between 2011 and 2015. The result showed that the number of plants in the first plot (fencing) were 23, with an average height of 43 inches and a diameter of 11.7 mm. In the second plot (fencing and fertile soil), 40 plants grew with an average height of 42 inches and a diameter of 10 mm, whereas in the third plot (fencing and trench), 45 plants developed with an average height of 48 inches and a diameter of 13 mm. However, the fourth plot (nontreated plants) showed poor germination with 8 plants, with an average height of 8.5 inches, and the diameter of plants was 3.7 mm. Therefore, the survival rate of plants in the first, second, and fourth plots remained unsatisfactory at the end of the research. In conclusion, the third treatment (fencing and trench) was the best suitable practice to stabilize oak forests in their natural zones.
在开伯尔-普赫图赫瓦省,尤其是奇特拉尔区的Sheshikoh山谷,橡树林的再生是一个令人担忧的问题。由于不受控制的放牧、土壤含水量低以及过度使用该植物作为薪材,橡树林的覆盖率不断恶化和枯竭,因此是导致橡树再生失败的主要原因。本研究旨在评估不同的处理方法及其对橡树林生长和再生的影响。这项研究是在奇特拉尔Sheshikoh山谷的橡树林中进行的,在那里建立了四块2-甲酰胺的地块。对每个小区分别进行了围栏处理、混合处理(围栏和肥沃土壤)、围栏和沟渠处理,并对对照小区及其再生能力进行了研究和比较。数据收集于2011年至2015年的3月和9月。结果显示,第一块地(围栏)的植物数量为23株,平均高度为43英寸,直径为11.7 在第二块地(围栏和肥沃的土壤),生长了40株植物,平均高度为42英寸,直径为10 mm,而在第三块地(围栏和沟渠)中,生长了45株植物,平均高度为48英寸,直径为13 然而,第四个地块(未处理的植物)表现出发芽不良,有8株植物,平均高度为8.5英寸,植物直径为3.7 因此,在研究结束时,第一、第二和第四块地的植物存活率仍然不令人满意。总之,第三种处理方法(围栏和沟渠)是稳定自然区橡树林的最佳合适做法。

Sentinel-2 imagery can identify forest and land fires in underground parts, surface fires, and crown fires. The dNBR and RBR spectral indices on Sentinel-2 images proved accurate in identifying. This study analyzed the index value for burned area mapping in wetland areas using Sentinel-2 imagery data in 2019 and hotspot data from the MODIS data. The indices used to identify the burned area and the severity of the fire was the differenced normalized burn ratio (dNBR) and relativized burn ratio (RBR). Visual validation tests were performed by comparing RGB composite images to check the appearance before and after combustion with dNBR and RBR results. The dNBR value accuracy was 91.5%, and for a kappa, the accuracy was 89.58%. The RBR accuracy was 92.9%, and the kappa accuracy was 0.91. The results confirmed that in the Banjarbaru area, RBR was more accurate in identifying burned areas than dNBR; both indices can be used for burned area mapping in wetland areas.
Sentinel-2图像可以识别地下部分的森林和陆地火灾、地表火灾和树冠火灾。结果表明,Sentinel-2遥感影像上的dNBR和RBR光谱指数识别精度较高。利用2019年Sentinel-2遥感影像数据和MODIS热点数据,对湿地地区火烧面积制图指标值进行分析。采用差分归一化燃烧比(dNBR)和相对燃烧比(RBR)作为火灾面积和火灾严重程度的识别指标。通过RGB合成图像与dNBR和RBR结果对比,进行燃烧前后外观的视觉验证试验。dNBR值的准确率为91.5%,kappa值的准确率为89.58%。RBR准确率为92.9%,kappa准确率为0.91。结果表明,在Banjarbaru地区,RBR比dNBR识别烧伤区域更准确;这两种指标均可用于湿地地区的火烧面积制图。

Industrial activities have various effects on biodiversity, posing significant threats to forest ecosystems. The current study describes the species composition, taxonomic diversity, and stand structure at Bhawal Sal forest, Gazipur, Bangladesh, as they are affected by industrialization. To achieve the goal, 30 different categorized industries within the forest were considered sampling points and three distance gradient sites viz. Site-1 = Adjacent to industries (0 m), Site-2 = 160 m distance and Site-3 = 320 m distance from industries were designated as treatments. A total of 90 quadrate plots (10 m × 10 m) were taken randomly, of which 30 plots were from each site. Through forest inventory, 46 species (24 trees, 8 shrubs, 5 climbers, and 9 saplings) were recorded from three sites. The study revealed that the stand density and basal area of mature trees (257 stems ha−1 and 8.06 ± 0.60 m2·ha−1) at Site-1 were significantly lower due to diverse industrial operations than other sites. Statistically, all the biodiversity indices of mature trees; Shannon–Wiener’s index (1.72), Simpsons index (0.82), Margalef’s index (1.38), Pielou’s evenness Index (0.39) was found to be lower at proximity to industries. The lowest species richness (12) of all plants was recorded from Site-1. However, the diameter and height distributions of Site-1 comprised young (10–20 cm·dbh) to medium-sized (20.1–30 cm·dbh) trees, while the medium to large sized (>30 cm·dbh) trees was contained at Site-3 in this study. The population structure of tree species at Site-1 also showed a fluctuating curve. Overall, this study highlights that plant ecosystems and tree population structure have declined tremendously due to industrialization. Hence, the current research could be significant for developing the management framework for the disturbed deciduous forest.
工业活动对生物多样性有各种影响,对森林生态系统构成重大威胁。目前的研究描述了孟加拉国加济布尔Bhawal Sal森林的物种组成、分类多样性和林分结构,因为它们受到工业化的影响。为了实现这一目标,考虑了森林内30个不同分类的行业的采样点和三个距离梯度站点,即站点-1 = 与行业相邻(0 m) ,站点-2 = 160 m距离和站点-3 = 320 m的距离被指定为处理。总共90个象限地块(10 m × 10 m) 随机抽取30个样点。通过森林调查,从三个地点记录了46种(24棵树、8棵灌木、5棵攀缘植物和9棵树苗)。研究表明,成熟树木的林分密度和基底面积(257茎ha−1和8.06 ± 0.60 m2·ha−1)显著低于其他地点,这是由于不同的工业运营。从统计上看,所有成熟树木的生物多样性指数;Shannon–Wiener指数(1.72)、Simpsons指数(0.82)、Margalef指数(1.38)和Pielou均匀度指数(0.39)在靠近工业的地方较低。在所有植物中,物种丰富度最低(12)的记录来自Site-1。然而,站点1的直径和高度分布包括年轻的(10-20 cm·dbh)至中等(20.1–30 cm·dbh)树木,而中大型(>30 cm·dbh)的树木。站点1的树种种群结构也呈现波动曲线。总的来说,这项研究强调,由于工业化,植物生态系统和树木种群结构急剧下降。因此,当前的研究对于制定受干扰落叶林的管理框架具有重要意义。

Moist tropical forests have a significant role in provisioning and regulating ecosystem services. However, these forests are under threat of deforestation and forest degradation. In Ethiopia, the moist evergreen Afromontane forests have the potential for carbon storage and support a high diversity of plant species. However, it is under severe threat of deforestation and degradation.This investigation was conducted to obtain adequate information on the carbon stock potential of the moist Afromontane forest of southwestern Ethiopia. A comparison of carbon stock was conducted between disturbed and undisturbed forests. A systematic sampling design was applied for recording woody species and soil data. A total of 100 main plots of 400 m2 were laid to record trees and shrubs with a diameter at breast height (DBH) ≥ 5 cm. The soil data were collected from 1 m2 subplots established at the four corners and the center of each main plot. The DBH and height were measured to calculate the aboveground carbon of trees and shrubs with DBH ≥ 5 cm. A total of 68 tree and shrub species belonging to 59 genera and 33 families were recorded. The mean carbon stock density was 203.80 ± 12.38 t·ha–1 (aboveground carbon stock) and 40.76 ± 2.47 t·ha–1 (belowground carbon stock). The highest proportion of aboveground carbon (t·ha–1) (42.34%) was contributed by a few tree individuals with DBH > 70 cm. The soil organic carbon stock (SOCS) (t·ha–1) for the depth of 0–30 cm is ranging from 58.97 to 198.33 across plots; the mean is 117.16 ± 3.15. The carbon stored in the moist Afromontane forest indicates its huge potential for climate change mitigation. Therefore, for the enhancement of forest biodiversity and carbon sequestration effective conservation measure and sound management approach is essential.
潮湿的热带森林在提供和调节生态系统服务方面发挥着重要作用。然而,这些森林正面临着砍伐森林和森林退化的威胁。在埃塞俄比亚,潮湿的常绿非洲山地森林具有碳储存潜力,并支持植物物种的高度多样性。然而,它正面临着森林砍伐和退化的严重威胁。进行这项调查是为了获得关于埃塞俄比亚西南部潮湿的阿夫罗蒙坦森林碳储量潜力的充分信息。对受干扰森林和未受干扰森林的碳储量进行了比较。采用系统抽样设计记录了木本物种和土壤数据。共有100块主地块,共400块 m2,用于记录胸径(DBH)的树木和灌木 ≥ 5. cm。土壤数据收集自 在每个主地块的四个角落和中心建立了m2的子地块。测量DBH和高度以计算DBH≥5的树木和灌木的地上碳 共记录了33科59属68种乔灌木。平均碳储存密度为203.80 ± 12.38 t·ha–1(地上碳储量)和40.76 ± 2.47 t·ha–1(地下碳储量)。地上碳(t·ha–1)的最高比例(42.34%)是由DBH>70的少数树木个体贡献的 cm。0–30深度的土壤有机碳储量(SOCS)(t·ha–1) cm在58.97到198.33之间;平均值为117.16 ± 3.15.储存在潮湿的阿夫罗蒙坦森林中的碳表明其在减缓气候变化方面具有巨大潜力。因此,为了增强森林生物多样性和固碳,有效的保护措施和健全的管理方法至关重要。

The study was conducted in the Harego dry Afromontane forest, Northeastern Ethiopia, to analyze woody species composition, diversity, structure, and regeneration status. To collect the vegetation data, a total of 67 sample plots measuring 400 m 2 20 m × 20 m were laid systematically. Species identity, abundance, height, and diameter at breast height (DBH) were recorded for each sample plot. Diversity, structural, and regeneration status were analyzed for the forest. A total of 50 woody species representing 35 families and 44 genera were identified and recorded. According to the IUCN Red List Category, Rhus glutinosa A. Rich and Prunus africana (Hook.f.) Kalkm. are vulnerable species. Fabaceae was the dominant family, and of the total species, 27 were shrubs, 19 were trees, and 4 were climbers. The species accumulation curve indicates that the majority of plant species in the study area were captured by our sampling efforts. The values of true Shannon (N1 = 17) and true Simpson (N2 = 11) indicate that species in the Harego forest are more or less evenly distributed. The abundance-frequency ratio of all woody species (WI = >0.05) indicates the heterogeneity of species composition. The total density and basal area were 4400 stems ha−1 and 9.66 m2 ha−1, respectively. The majority of the species fallen into the lower IVI classes. The diameter and height class distribution revealed an inverted J-shape. The increase in population demand and disturbance shows a high variation in stand structure and hampered natural regeneration, which needs immediate conservation actions.
本研究在埃塞俄比亚东北部的Harego干燥的Afromontane森林中进行,以分析木本物种的组成、多样性、结构和再生状况。为了收集植被数据,系统地铺设了67个400m2 20m×20m的样地。记录每个样地的物种身份、丰度、高度和乳高直径(DBH)。对森林的多样性、结构和再生状况进行了分析。共鉴定和记录了代表35科44属的50种木本植物。根据国际自然保护联盟红色名录分类,Rhus glutinosa A.Rich和Prunus africana(Hook.f.)Kalkm。是易受伤害的物种。蚕豆科为优势科,灌木27种,乔木19种,攀缘植物4种。物种积累曲线表明,研究区域的大多数植物物种都是通过我们的采样工作捕获的。真Shannon(N1)的值 = 17) 和真正的Simpson(N2 = 11) 表明哈雷戈森林中的物种分布大致均匀。所有木本物种的丰度频率比(WI = >0.05)表示物种组成的异质性。总密度和基底面积分别为4400茎ha−1和9.66 m2 ha−1。大多数物种属于较低的IVI类。直径和高度等级分布呈倒J型。种群需求和干扰的增加表明林分结构变化很大,阻碍了自然再生,需要立即采取保护行动。

The objective of the research was to evaluate the effect of relative humidity (RH) and moisture content (MC) on the incidence of pathogenic fungi on the seeds of Agave lechuguilla, Lippia graveolens, and Nolina cespitifera. Seeds were stored 90 days at 60, 75, 80, and 85% RH, and results were processed with a correlation analysis in the R software using the Spearman test. Higher fungi incidence (FI) in seeds was found from 10 to 20% RH; however, correlation between RH and MC of seeds was positive with r = 0.311 and p = 2.2 × 10 − 16 . In general, RH is related to MC, but not to fungi incidence, which is related mainly to MC of seeds. Correlation between RH and FI for each seed species was not significant, r = 0.026, −0.040, and 0.071 and p = 0.687 , 0.540, and 0.272 for A. lechuguilla, N. cespitifera, and L. graveolens, respectively. There was a positive correlation between the MC of seeds with fungi incidence; a negative correlation between the RH and the FI; and a positive correlation between the RH and the MC of seeds. In this type of seeds (orthodox), the MC is probably the most important factor in determining its longevity. The seeds under study can be stored in a 60% to 75% RH. Five fungi genera were found, predominating Aspergillus with five identified species.
本研究的目的是评估相对湿度(RH)和含水量(MC)对龙舌兰、李皮和野百合种子上病原真菌发生率的影响。将种子在60、75、80和85%相对湿度下储存90天,并使用Spearman检验在R软件中进行相关分析来处理结果。种子中真菌发生率(FI)在10%-20%RH范围内较高;种子的相对湿度和MC与r呈正相关 = 0.311和p=2.2×。一般来说,RH与MC有关,而与真菌的发病率无关,真菌的发病主要与种子的MC有关。每种种子的RH和FI之间的相关性不显著,r = A.lechuguilla、N.cespitifera和L.graveolens分别为0.026、-0.040和0.071,p分别为0.687、0.540和0.272。种子MC与真菌发生率呈正相关;RH和FI之间呈负相关;种子的相对湿度与MC呈正相关。在这种类型的种子(正统)中,MC可能是决定其寿命的最重要因素。研究中的种子可以储存在相对湿度为60%至75%的环境中。发现5个真菌属,以曲霉属为主,已鉴定5个种。

The development of dyeing frm natural substances for silk fabrics has been rapidly growing in recent years. This study aimed to explore the plant species prodsucing unique dyes and patterns on silk fabrics. The flowers and leaves of some plant species found at the research sites were assayed for their color and shape expression on the fabrics. The dyeing technique applied was the bundle dyeing or ecoprinting technique on the fabric’s surface with mordant alum and myrobalan. We obtained 297 plants consisting of 95 families and 181 genera. The plant species producing colors were trees (48.4%), shrubs (30.5%), and herbs, vines, ferns, and lycopods (21.1%). The plant species samples obtained were 213 (71.7%) producing color and 84 (28.3%) species not expressing color. The leaves and flowers producing colors and patterns on the fabrics suitable for bundle dyeing were 126 species and 19 species, respectively. The leaves produce colors without shape patterns; thus, they have potential roles as dyes for the dipping technique.

The objectives of the study were to evaluate the effect of pretreatment methods on germination of Senna spectabilis seed and determine the effect of pretreatment methods on height and root collar diameter growth of Senna spectabilis seedlings. The experimental treatments involved were control; seeds soaked in cold water for 12 h, 24 h, and 48 h; seeds soaked in hot water and allowed to cool for 12 h, 24 h, and 48 h; and nicked seeds using secateurs. The experiment was arranged in a completely randomized design (CRD) with four replications. The data variables assessed were seedling height, root collar diameter, and survival rate. Data were subjected to one-way ANOVA using Minitab software. Results showed that there were significant differences p ≤ 0. 05 among treatment means on germination, seedling height, and root collar diameter, while the survival rate was not statistically significant p ≥ 0.05 . Nicked seeds and those soaked in hot water and allowed to cool for 12 h had an outstanding performance in terms of germination and seedling growth. It is, therefore, recommended that farmers should be encouraged to use nicked and hot water soaked for 12 h seed in order to achieve high germination and growth efficiencies in their homestead gardens.

Human-wild animal conflict has serious conservation consequences, both for populations of wild animals and for the people who live around wild animals’ habitats. The aim of this study was to assess the human-wild animal conflict in Banja Woreda, Awi Zone, Ethiopia. First, the area was selected purposively because it is expected to be prone to a high level of human-wild animal conflict, and then the selected areas were stratified based on the distance to wild animals’ habitats. A total of 95 household heads (HHs) from the two kebeles were interviewed using structured and semistructured questionnaires. Additional information was also gathered through focus group discussions (FGDs), key informant interviews, and personal observation during data collection. About 84 (88%) of the respondents replied that wild animals had an effect on the livelihood of the local communities through both crop and livestock loss. The crop and animal loss was different across the distance categories of the study area ( P < 0.05 ). The highest proportion of loss was reported in the closest settlement than far-located settlements. The chi-square association test shows that there was a significant association ( P < 0.05 ) between livelihood activity across crops and domestic animal loss. The farmers who led their livelihoods in both farming and livestock activity reported higher animal and crop losses than the only farming or livestock activity. The crop types that were more raided by wild animals were maize and potato. The risks of crop raiding were significantly different among crop varieties ( P < 0.05 ). Wild animals affected crops in different development stages, and mature stage ranked the first followed by fruiting stage. Crop growth stages that were attacked by wild animals showed significant variations ( P < 0.05 ). Of the crop type that was attacked by wild animals, potato was highly attacked, which reaches to 113.8 quintals (28%), followed by maize 96 quintals (23%) and small millet 74.7 quintals (18%) within three years. The loss of crops in the kebeles was not significantly different ( P > 0.05 ). Wild animals also affected the domestic animals; accordingly, 79 (83.2%) of the respondents replied that wild animals attacked all domestic animals and the remaining 16 (16.8%) said wild animals attacked goats, sheep, and chickens. However, the animal loss in the kebeles was not significantly different ( P > 0.05 ). The trend of the population status of wild animals was significantly different among the perceptions of respondents ( P < 0.05 ). The settlement near the forest habitat of wild animals and habitat loss due to agricultural expansion and deforestation were the major causes of conflict. The proportion of the causes of human-wild animal conflict in the area was significantly different ( P < 0.05 ). According to the respondents, the most effective controlling mechanisms of the conflict were guarding
人与野生动物之间的冲突对野生动物种群和野生动物栖息地周围的人们都产生了严重的保护后果。本研究的目的是评估埃塞俄比亚Awi地区Banja Woreda的人与野生动物冲突。首先,有目的地选择该地区,因为预计该地区容易发生高水平的人与野生动物冲突,然后根据与野生动物栖息地的距离对所选地区进行分层。使用结构化和半结构化问卷对来自两个kebele的95名户主进行了访谈。还通过焦点小组讨论、关键线人访谈和数据收集期间的个人观察收集了更多信息。大约84(88%)的受访者回答说,野生动物通过作物和牲畜的损失对当地社区的生计产生了影响。研究区域不同距离类别的作物和动物损失不同(P 0.05)。野生动物也影响了家畜;因此,79名(83.2%)受访者回答说,野生动物袭击了所有家畜,其余16名(16.8%)受访者表示,野生动物攻击了山羊、绵羊和鸡。但是,动物在烤串中的损失没有显著差异(P>0.05)。调查对象对野生动物种群状况的认知趋势存在显著差异(P<0.05)。野生动物森林栖息地附近的定居点以及农业扩张和森林砍伐导致的栖息地丧失是冲突的主要原因。人与野生动物冲突的原因在该地区所占比例有显著差异(P<0.05)。据受访者称,冲突最有效的控制机制是守卫,其次是围栏和夜间在农田里滑倒。在受访者总数中,65人(68.4%)表示,守卫是最有效的冲突控制机制,可以保护作物和牲畜。为了限制人类与野生动物冲突的负面影响,需要对野生动物栖息地进行良好的管理,例如尽量减少农业扩张和过度放牧,只为野生动物划定森林栖息地,并提高当地社区的意识。

More than 80% of the urban and periurban population in Tanzania depend on charcoal as their main source of energy for cooking. This charcoal is supplied from natural forests, mainly Miombo woodlands, and the high charcoal consumption is a main trigger for deforestation, forest degradation, and climate gas emissions. The country’s urban population is increasing at an annual rate of 5-6%, and better understanding of the urban demand for charcoal is of high interest regarding the country’s energy development, climate mitigation, and land use. We surveyed 360 households situated in the Tanzanian cities Dodoma, Morogoro, and Mtwara and analyzed statistically the impacts of household income, charcoal prices, and household size on the per capita charcoal consumption. For the total sample, statistically significant elasticities were found to be 0.03, −0.13, and −0.62 for per capita income, charcoal price, and household size, respectively. In the low-income group, the elasticities of charcoal price and household size were found to be statistically significant with the values of −0.44 and −0.59, respectively, whereas in the middle-income group, the household size was the only statistically significant variable, with elasticity −0.81. In the high-income group, we got statistically significant elasticities of 0.17 for per capita income and −0.44 for household size. These results are based on small samples and should be followed up by larger surveys.
坦桑尼亚80%以上的城市和近郊人口依赖木炭作为烹饪的主要能源。这种木炭来自天然林,主要是Miombo林地,木炭的高消费量是森林砍伐、森林退化和气候气体排放的主要诱因。该国的城市人口正以每年5-6%的速度增长,更好地了解城市对木炭的需求对于该国的能源开发、气候缓解和土地利用具有重要意义。我们调查了坦桑尼亚城市多多马、莫罗戈罗和姆特瓦拉的360户家庭,并统计分析了家庭收入、木炭价格和家庭规模对人均木炭消费的影响。对于总样本,人均收入、木炭价格和家庭规模的统计显著弹性分别为0.03、-0.13和-0.62。在低收入群体中,木炭价格和家庭规模的弹性具有统计学意义,分别为-0.44和-0.59,而在中等收入群体中家庭规模是唯一具有统计学意义的变量,弹性为-0.81。在高收入群体中,我们得到了人均收入0.17和家庭规模-0.44的统计显著弹性。这些结果是以小样本为基础的,应该进行更大规模的调查。
