Study Sites

The present study aimed to investigate the structure, composition and diversity of the over-wintering aquatic bird community of Poyang Lake, including Poyang Lake National Nature Reserve (PNNR), Nanji National Nature Reserve (NNNR) and Duchang Provincial Nature Reserve (DPNR), China. After the preliminary survey, birds surveyed from vantage points at each study site between the years 2016 and 2020 in the winter season. A total of 58 bird species belonging to nine orders and 13 families were observed. The study showed variation in effective species numbers (Species richness, Shannon’s diversity and Simpson’s diversity) among the three study sites and the survey years. Nanji National Nature Reserve had the highest avian diversity, whereas Duchang Provincial Nature Reserve had the lowest. Globally threatened bird species, Siberian Crane (critically endangered), Oriental Stork (endangered), found in our study sites. However, the current management practices of the nature reserve and conservation of this globally threatened bird species are inadequate, especially of Duchang Provincial Nature Reserve. Therefore, for long term conservation of birds in these areas, it needs continuing intentional improvement of the sites and awareness creation to the local community.

The study deals with the influence of the structure, texture and dynamics of a spruce-beech primeval forest on the bird community in Skalná Alpa National Nature Reserve in the Veľká Fatra Mts. (West Carpathians, Slovakia) in the years 1982–2002. The abundance of Norway spruce (Picea excelsa Lam.) was highest both in the optimum and decomposition stage. In the growth stage the number of Norway spruce (Picea excelsa Lam.) trees was quite low. The texture of spruce-beech virgin forest was very variable. Percentage ratios of individual stages on the area of 42.16 ha were as follows: growth stage 38.3%, optimum stage 20.1% and decomposition stage 41.6%. Altogether 46 bird species were represented in the bird community during the spring season. Mean total density was 85.8 ind/10 ha. The bird community consisted of 52 species in the summer season, 45 in the autumn migration season, 34 in the winter season, and of 47 in the spring migration season. The highest density was found in the bird community during the autumn migration season (109.8 ind/10 ha), the lowest in the winter season (24.6 ind/10 ha). During the spring migration season, both the spectrum of bird species and total density of bird community increased by the number of migratory species that came back from winter habitats.

For the first time, and in a large spatial scale, the influence of ecological properties on the aquatic bird community of black water lakes in Brazilian Amazonia is evaluated. Bird surveys were conducted in 45 lakes. A total of 3626 individuals in 48 bird species were recorded; of these, 31 are aquatic, and 18 of these are primarily piscivorous. Bird richness and abundance were not significantly related to lake shape and productivity but were influenced by hydrological period (low versus high), water depth, transparency, lake isolation, and habitat richness. Matrices of bird species by lake were subjected to multivariate analyses (NMDS) to evaluate how these parameters influence bird community. The variation in bird species composition was positively correlated to lake depth and isolation and negatively correlated to water transparency and habitat richness. The results indicate that period, lake physical characteristics (depth, water transparency), isolation, and habitat richness are determinants of aquatic bird community composition in the black water lake systems of Amazonia.

National nature reserve (NNR) is the important ecological baseline of the ecosystem security of the country. However, it is under the pressure of mass tourism, low participation of local community, and improper management. It is a matter of great urgency to determine strategies and tools in support of the balance between conservation and development of NNR. At present, the management system of NNR in China is a system where the country supervises and the local government manages. The perception of the NNR’s management aim has direct influence on the management efficiency and protection effect. In this paper, the issue with Matoushan National Nature Reserve in Jiangxi Province has been analyzed as an example. Local residents and administrators’ attitudes and perceptions of the management goals of the NNR were measured from three aspects: (1) response to current policies practiced in the reserve; (2) degrees of perception of community co-management; (3) expectation for future development of the reserve. Based on the measurement of community attitude and intention toward four dimensions of ecotourism and assessment of the values and current threats to Matoushan NNR, five sustainable development strategies have been put forward which involve ecological conservation and recovery, local culture revitalization, industry and program planning, educational tourism planning, and periphery development and management. Seeing the resources inside the reserve areas as a natural, cultural, social and economic asset, ecotourism planning is holistic by integrating the goals of natural resources conservation and those of social and economic improvement in revitalizing and managing NNR.

The study was undertaken in Mecha District, Amhara National Regional State, Northwestern Ethiopia, in 2012/2013. The objectives of the study were to assess production purpose and management practices of pig and to identify constraints and generate baseline information for further research and development. From the district, 6 Kebeles (name of local administration in Ethiopia) were identified and from each Kebele 15 households were selected making the number of respondents 90. A pretested semistructured questionnaire was employed for collecting data through interview and face to face discussion with the pig owners including key informant group discussion and secondary sources. Multivisits to study sites were also made to observe the feeding, housing, and other pig management practices. The results indicated that the purpose of pig production is mainly targeted for additional income and profit for the household in which pigs are sold for external markets as pork is not consumed by local community. Results indicate that pig keepers were farmers or nonfarmers with small land holding and people engaged in other types of work. The major feed source for pig was grazing, followed by crop residue feeding and supplementing with household and agricultural by-products. Pigs are kept in house at least for the night, though the pig house was not separated by age or physiological stage. The most important constraints of pig production in the study area were feed shortage, poor access to veterinary services, and poor market linkage.
