Abstract:
Functional trait diversity represents ecological differences among species, and the structure of waterbird communities is an important aspect of biodiversity. To understand the effect of meteorological changes on the waterbird functional diversity and provide suggestions for management and conservation, we selected a study area (726 km2) in Liaohe Estuary, located in northeast China. We explored the trends of the waterbird functional diversity changes in response to meteorological factors using fourth corner analysis. Our study demonstrated that temperature was a key factor that impacted waterbird functional diversity in spring, while precipitation had a greater impact in autumn. The population size of goose and duck was positively associated with temperature and negatively with precipitation, while that of the waders (Charadriiformes) showed opposite association trends. Herbivores and species nesting on the bare ground exhibited responses to meteorological factors similar to those of geese and ducks, while benthivores and waterbirds nesting under grass/shrubs exhibited trends similar to those of waterbirds. Waterbirds with smaller bodies, shorter feathers, and lower reproductive rates preferred higher temperatures and less precipitation than other waterbirds. In addition, we observed seasonal variations in waterbird functional diversity. In spring, we should pay attention to waders, herbivores, and waterbirds nesting on the bare ground when the temperature is low. In autumn, waders, benthivores, and omnivores need more attention under extreme precipitation. As the global climate warms in this study area, waterbird functional diversity is expected to decline, and community composition would become simpler, with overlapping niches. Biodiversity management should involve protecting intertidal habitats, supporting benthic macrofaunal communities, preparing bare breeding fields for waterbirds favoring high temperatures to meet their requirements for population increase, and preventing the population decline of geese and ducks, herbivores, and species nesting under grass/shrubs. The findings of our study can aid in developing accurate guidelines for waterbird biodiversity management and conservation.

Abstract:
Avian botulism poses a significant risk to waterbird health in Australian wetlands. This paralytic, often fatal, disease occurs when birds ingest a neurotoxin produced by the bacterium Clostridium botulinum. Our current understanding of avian botulism comes largely from studies in the northern hemisphere, with many of these studies linking outbreaks of avian botulism with poor water quality. The Murray–Darling Basin provides the most important breeding habitat for colonial waterbirds in Australia, but the frequency of large-scale breeding events has declined, and waterbird populations are near record-low numbers. Avian botulism has the capacity to have significant impacts on waterbird recruitment if not managed appropriately. We propose that environmental water-management strategies that aim to maintain water quality through flow delivery to waterbird colonies could mitigate the risk of botulism outbreaks and contribute to waterbird population recovery.

Abstract:
SummaryUnderground coal mining in the North China Plain has created large-scale subsidence wetlands that may attract waterbirds that use them as complementary habitats. However, no study has been conducted to understand avian use of these created wetlands, inhibiting the formulation of effective management plans. Here, we carried out 12 semi-monthly surveys in 55 subsidence wetlands during the 2016–2017 migration and wintering period and performed direct multivariate analyses, combined with variance partitioning, to test the effects of multi-scale habitat variables on the waterbird assemblages. A total of 89 349 waterbirds representing 60 species were recorded, with seasonal fluctuations in species richness and bird abundance. Waterbird community structures were shaped by four groups of variables at local, landscape and human levels with different effects among seasons. Anthropogenic disturbance was the most important factor group, negatively affecting most guilds. Waterbirds in this human-dominated environment are under a variety of potential threats that should be further studied. The subsidence wetlands are still expanding, and if managed effectively, may provide important complementary habitats for a wide array of waterbird species, particularly for those migrating along the East Asian–Australasian Flyway. Our study provides key baseline data regarding the waterbird communities and may help with the designing of effective management and conservation plans.

Abstract:
Abstract Waterbirds constitute a prominent biota and reflect the ecosystem health and functionality of the freshwater wetlands. Documentation of the bird species assemblages of wetlands is therefore carried out as a part of monitoring of wetlands from a sustainability viewpoint. Using the emerging wetland of Purbasthali, West Bengal, India, as a model study area, the diversity of the associated bird species was estimated to supplement necessary information for conservation management of birds and ecosystems. The point count method was applied to count the waterbirds from each sighting location with a 25 m radius covering 360° arc and the counting period lasted 10 min for each site, and counts were made in the winter of 2016/2017. The data on the waterbirds encountered were recorded and subjected to diversity analysis, including the residential status, global population trend and feeding guilds. Apparently, the wetland was considered as suitable habitat for 27 waterbird species, which could be grouped under 24 genera, 10 families and 5 orders. Among these, the family Anatidae with maximum relative density and abundance dominated in the wetland. Out of the 27 recorded species, 5 species were widespread winter visitors, 3 species widespread resident, as well as, widespread winter visitors and 2 species were sparse local winter visitors. A globally near threatened species, the Black-headed Ibis (Threskiornis melanocephalus) was very common in the sampling sites. The waterbird assemblage in the wetland was dominated by carnivores followed by omnivores and herbivores. The abundance of the waterbirds with considerable variations in the foraging guild reflects availability and exploitation of multiple resources of the Purbasthali wetlands. Prominence in the differences in relative abundance of the different waterbirds could be linked with the heterogeneity in the habitat quality. The present information on waterbird assemblage calls for appropriate measures for conservation of the species and appropriate management of Purbasthali wetlands.

Abstract:
We can use aerial surveys of waterbirds to identify high-conservation-value wetlands, estimate species’ abundance and track changes in wetland condition. Two major approaches prevail. Transects to estimate a few species (1–20, often ducks) are predominantly used in North America and counts of entire waterbird assemblages on discrete wetlands are favoured in Australia. Such differences reflect wetland type, discrete (whole count) and continuous (transect) sampling, different objectives and history. There are few continuous large-scale aerial surveys of waterbirds, despite cost efficiencies and effectiveness. We review the eastern Australian waterbird survey that samples about one-third of the continent (2.697 million km2). Each October, during 1983–2007, all waterbirds were estimated on an average of 811 wetlands, within ten 30-km-wide survey bands, separately extending across latitudes from the east coast to central Australia. The survey has demonstrated the importance of arid wetlands for waterbirds and provided management data on distribution, abundance and breeding of waterbirds. Most significantly, long-term temporal data for individual wetlands provided strong evidence for the impacts of water resource development (dam building, diversion of water). These data have influenced wildlife management, river rehabilitation and restoration policies at a national scale.

Abstract:
SummaryAnthropogenic conversion of natural wetlands into artificial wetland habitats has produced complex wetland landscapes worldwide. In this study we investigated the responses of migratory and wintering waterbirds to five artificial wetland habitats (aquaculture ponds, paddyfields, irrigation canals, open water reservoirs and saltpans) within a novel natural-artificial wetland landscape, Yellow River Delta (YRD), eastern China from October 2007 to May 2008. The results showed that almost all bird community indicators in the YRD natural wetlands were higher than those in adjacent artificial wetlands. Across the landscape, natural wetlands remained most important for all waterbird guilds, and more than 90% of waterbird populations were dependent on these habitats. Artificial wetlands mainly provided a secondary role, supporting about 70% of waterbird species (including six species that reached 1% of their global or biogeographical flyway populations), but with distinctive functional capacity for specific waterbird guilds in different artificial wetlands. The conservation value of artificial wetlands is often ephemeral, mainly during autumn, for specific migratory waterbirds and complements that of remaining areas of natural wetlands. Therefore, the utilisation patterns of artificial wetlands are highly temporal and the majority of species are dependent on areas of natural wetland. A comprehensive study of the inter-seasonal and inter-annual variations in these different habitats and dependence by the various guilds in the YRD is required to enable the true value of these habitats to be understood. We suggest that the conservation of artificial wetlands should not be at the expense of natural wetlands, which should remain the priority for wetland landscape management. Management to maintain the existing artificial wetlands for migrating and wintering water birds should target habitat features that are absent or limited in natural wetlands thus increasing the carrying capacity of the YRD landscape.

Abstract:
In total, 58 species of waterbird were recorded on the grassed floodplain of the Middle Fly during surveys in December 1994 and April 1995. The floodplain is an important dry-season habitat both in New Guinea and internationally, with an estimated (+/- s.e.) 587249 +/- 62741 waterbirds in December. Numbers decreased 10-fold between December and April to 54914 +/- 9790: the area was less important during the wet season when it was more deeply inundated. Only magpie geese, comb-crested jacanas and spotted whistling-ducks were recorded breeding on the floodplain. The waterbird community was numerically dominated by fish-eating species, especially in December. Substantial proportions of the populations of many species that occurred on the Middle Fly in December were probably dry-season migrants from Australia, suggesting that migration across Torres Strait is important to the maintenance of waterbird numbers in both New Guinea and Australia.

Abstract:
Wuliangsuhai Lake is one of the key wetlands in the vast arid region of northwest P.R. China, and provides critical breeding and staging habitats for waterbirds in the East Asian–Australasian Flyway and the Central Asian Flyway. It also provides livelihoods for local communities through fishing, reed harvesting and tourism. Balancing conservation and economic use of the lake requires a thorough understanding of the dynamics of waterbird communities. From April 2011 to March 2012, we conducted a monthly waterbird survey on the lake, and counted more than 165,900 individuals which belonged to 87 species, 14 families and six orders. There were significant temporal differences in species richness and abundance. The highest migration activities of the birds were recorded in May and August. Shallow water and open water areas were mostly used by waterbirds with over 50% of the species, and a population density of 1,000 individuals per km2 recorded. Human use of the wetland mainly consists of fishing, tourism and reed harvesting, which may have a significant impact on waterbirds. The most intensive human activities occurred in July and August, in open water and shallow water. An adaptive management plan to reduce the negative impact of fishing and tourism activities in summer and autumn, to rationalise reed harvesting in winter and to control eutrophication are critical management measures in addressing threats to the ecological characters of the site.

Abstract:
SummaryLake Junín is famous for the abundance and diversity of breeding, staging and wintering waterbirds. The lake supports the entire world population of three species or subspecies: Junín Grebe Podiceps taczanowskii, Junín Rail Laterallus tuerosi and the endemic subspecies of the White-tufted Grebe Rollandia rolland morrisoni. Surveys undertaken in the 1930s, 1960s, 1970s and 1980s confirmed the lake’s importance in the Andes, however there has been no recent assessment of its waterbird community. We undertook waterbird counts between 6 and 20 February 2014 from the lakeshore and by boat. Despite using differing survey methods, we nevertheless conclude that the relative abundance of waterbird species has changed dramatically compared to earlier counts. Most notably, the Junín Grebe has experienced a major decline since the 1930s when the species was considered extremely abundant and another native fish-eating species the White-tufted Grebe also appears to have declined. In contrast the Northern Silvery Grebe Podiceps juninensis, classified as ‘Near Threatened’, has apparently become more abundant. Numbers of Puna Teal Spatula puna and Common Gallinule Gallinula galeata seem to have crashed, presumably reflecting the general loss of submerged vegetation. In spite of a major decline in waterbirds overall, the Junín area holds numbers of migratory shorebirds, perhaps as a consequence of local hunting restrictions and awareness campaigns. Lake Junín is a candidate for listing on the Montreux Record under the Ramsar Convention as a wetland showing serious change in ecological character. Management planning should proceed to balance conflicting interests at the lake. Actions to re-establish a clear water column by reducing eutrophication (from settlements in the catchment) as well as sedimentation and heavy metals (from upstream mining) will contribute to improving ecological functions and to secure waterbirds including the endemics.

Abstract:
Abstract We surveyed birds on grain and nongrain fields in the Tulare Basin of California treated postharvest with two types of flooding that varied in duration and depth of water applied (flooded-type [FLD] fields: <1 cm–1.5 m for >1 wk; irrigated-type [IRG] fields: <1–15 cm water for <1 wk at a time). Our goal was to compare use of these field types by birds to guide habitat conservation in the region. During 19 August–6 December 2005, we counted a total of 80,316 birds during 23 surveys of 5 FLD fields (four wheat, one alfalfa) and 8,225 birds during 38 surveys of 33 IRG fields (23 cotton, 4 tomato, 3 wheat, 1 alfalfa, 1 oat, 1 fallow). We recorded 14 waterfowl (13 duck, 1 goose), 29 other waterbird (coots, shorebirds, grebes, pelicans, herons, egrets, gulls, terns), and 14 nonwaterbird (passerines, raptors, and vultures) species on FLD fields compared to 5 duck, 14 other waterbird, and 9 nonwaterbird species on IRG fields. Species composition differed by field type; waterfowl comprised a greater percentage (FLD vs. IRG, 16.2% vs. 1.3%), other waterbirds a similar percentage (80.4% vs. 71.6%), and nonwaterbirds a lower percentage (3.5% vs. 27.1%) of birds on FLD than on IRG fields. The modeled density estimate of waterfowl was 108 times greater on FLD than IRG fields and 7.4 times greater on grain than nongrain fields. The density estimate of other waterbirds was 11.8 times greater on FLD than IRG fields and 4.4 times greater on grain than nongrain fields. The density estimate of nonwaterbirds was 14.3 times greater on grain than nongrain fields but did not differ by flood type. Long duration (i.e., >1 wk) flooding increased waterbird use of grain fields in the Tulare Basin more than in the northern Central Valley. Thus, even though water costs are high in the Tulare Basin, if net benefit to waterbirds is considered, management programs that increase availability of FLD fields (especially grain) in the Tulare Basin may be a cost-effective option to help meet waterbird habitat conservation goals in the Central Valley of California.

Abstract:

Rice not collected by harvesters and natural seeds are important foods for waterfowl. Estimation of abundance of these seeds is necessary for calculating waterfowl habitat conservation needs in the Louisiana Chenier Plain (LCP) and Texas Mid-Coast (TMC). My objectives were to quantify dry mass of rice and other seeds from August-November 2010, and estimate waterbird abundances on farmed and idle ricelands in these regions from December 2010-March 2011. Rice abundance in farmed ricelands ranged from 159.7 kg/ha (CV = 66.6%) to 1,014.0 kg/ha (CV = 8.3%). Natural seed abundance in idle ricelands ranged from 99.7 kg/ha (CV = 32.9%) to 957.4 kg/ha (CV = 17.2%). Greatest waterbird densities occurred in shallowly flooded disked ricelands (mean = 7.35 waterbirds/ha, 90%; CI = 2.37-19.70). Ratoon, disked, and shallowly flooded ricelands are important habitat for non-breeding waterbirds but variable estimates of seed and waterbird abundances warrant continuation of this study.

BACKGROUND: There were perceptions that doctors as Medical Superintendents were unable to provide proper financial management of hospitals, thus administrators were appointed to manage hospitals irrespective of qualifications. The aim of the study was to determine how public hospitals are managed in Waterberg district (Limpopo province). METHOD: A cross sectional survey was conducted among 27 hospital managers in the Department of Health Limpopo province, in Waterberg district hospitals. A self -administered questionnaire was used for data collection. Data were analyzed using SPSS version 22.0, where both descriptive and inferential analysis was conducted. RESULTS: Of the 27 managers, 59.3% were females 40.7% compared to males. 96.3% of managers reported that they did not correctly implement PMDS and polices on RWOP were not applied. There was no statistical difference in management styles, according to gender (p>.05) and managers had a fair working relationship among themselves. CONCLUSION: According to the study, there is a great need to train hospital managers in management skills and other related policies, and giving them support in terms of resources such as: staffing especially health professionals, financial and working resources.

The aim of the study is to evaluate the implementation of the strategic planning and management in Waterberg District municipalities and to identify any constraints that might be affecting the implementation of strategic planning and management which is the basis for poor service delivery, which in turn, causes service delivery protests by members of the public against municipalities, and in order to provide policy recommendations. Therefore, the approach to the research is qualitative because the study solicited for views and opinions of respondents, in this case, public officials, politicians and members of the public. The secondary data aspect included the reviewing of documents of different municipalities in terms of planning and their own management styles. The quantitative approach is also applied in this study to validate the municipal performance score cards which is a content analysis. Data were collected through questionnaires and interviews. The findings reflected the key issues with regard to the impact of the implementation of strategic planning and management in municipalities in the Waterberg district Limpopo Province. The study revealed appropriate opportunities for possible interventions to improve the implementation of strategic planning and management. The general conclusion as revealed by the study is that the municipal strategic plans are not successfully implemented and not properly managed. The audit opinions awarded to the municipalities bear reference to the matter. The study provided recommendations for municipalities to improve on the implementation of strategic planning and management. For instance, strategic plans need to be aligned with other municipal plans and the plans of other government spheres, namely, the provincial and national spheres of government; it is imperative that skilled personnel be appointed, the staff and councillors of a municipality must be trained and retained in order to ensure a high level of service provision; municipal capacity building should be a core element of a broader performance management strategy and all stakeholders of the municipalities should be capacitated and trained in terms of policy formulation so that they understand what is expected of them in terms of policy analysis, formulation and policy evaluation

Abstract:

No evaluations of plant and wildlife communities in Wetlands Reserve Program wetlands have been conducted in the Mississippi Alluvial Valley. Therefore, I evaluated active and passive moist-soil management (MTYPE) and early and late draw-down on plant communities, waterbird use, and water quality on 18 WRP lands, Mississippi, 2007-2009. Active-early sites had greater waterfowl Vegetative Forage Quality (VFQI), percentage occurrence of grass, plant diversity, and structural composition than passively managed sites (P < 0.10). I modeled variation in densities of wintering waterbirds; the best model included VFQI*MTYPE and decreased % woody vegetation (wi ≥ 0.79). Additionally, waterbird densities varied positively with active-late management (R2 ≤ 0.27), as did duck species richness with flooded area (R2 = 0.66). I compared water quality parameters among managed wetlands and drainage ditches but did not detect differences due to variability. Therefore, wetland restoration on WRP lands should focus on active management and maximizing wetland area.

Thesis (Ph.D. (Curriculum Studies)) -- University of Limpopo, 2016
The main purpose of this research study is to investigate and analyse the role of the Principal towards effective educational leadership in selected Secondary schools in Waterberg Education District. The effectiveness of the educational leadership depends on the educational managers’ personal backgrounds, con-duciveness of the school climates, positive learning school cultures, availability of resources in the classrooms, utilisation of learner-teacher support material (LTSM), effective organisation of educational excursions, and other related issues. Principals, by virtue of their positions need to be empowered so as to coordinate activities and provide resources that can be used to enhance effect-tive educational leadership. The most important aspect pertaining to effective educational leadership in schools, is that it must be managed properly. This actually implies that correct and relevant resources should be provided to reinforce the quality of effective educational leadership. The primary study revealed that effective educational leadership cannot be achieved by school Principals in isolation, but through the School Management Team as a whole. Due to the nature of the study, the researcher has employed phenomenology, stratified random sampling and qualitative research design to achieve the in-tended goal of the research project. The researcher has also used case studies and interview research instruments to collect relevant data from twenty (20) SMT members in area of the study. The data collected through case studies and interviews was analysed by coding derived from audio tape recorder. Descriptive analysis was used to analyse the data whose findings were based on to make conclusions and recommendations. The results indicated that the role of the Principal contributes significantly to the quality of effective educational leadership. The results also showed that there is a need for continued support from the members of the School Management Teams. The need for support from the parents, SGBs and government in terms of resources, is vital. The abovementioned support, can also assist the Principals to make a positive impact on effective educational leadership. The researcher believes that, if the findings and the recommendations from the study can be applied properly, they can add value to the educational practice in Waterberg District in particular and Limpopo Province as a whole.

Spreadsheet programming is used to model the water budget and water management systems of the Upper San Pedro River Basin, Arizona, to examine how hydrologic, demographic, climatic, and economic conditions affect this budget; and how water management policies may affect the budget over the next twenty years. The model represents relationships among urban and rural population and median incomes; urban and rural domestic water consumption; agricultural and industrial consumption; domestic, agricultural, and industrial return flows; phreatophyte and other evapotranspiration losses; natural surface and ground-water recharges and discharges; head-dependent flow between a floodplain aquifer and the river; head-dependent flow between a regional aquifer and the floodplain aquifer; and changes in aquifer storage. Applications indicate that stringent conservation measures and reductions in irrigation are necessary to significantly reduce ongoing losses to storage in both aquifers, which also threaten river discharges and the viability of riparian habitat in the basin.

Abstract Before the 1970s, the central government took a long-term centralization of governance. In the beginning, the implemental of the project of conservation, invariably to insist on strictly protect the use of natural resources. There wasn’t any mechanism of public participation to follow. A gap between the ideality and the reality, make hostility between the public and government. It has gradually emphasized to take the natural conservation connection with locality, and carried out the natural conservation project together. The decentralization of government’s natural conservation power to other locality level is the realization of decentralization institution we used in natural conservation aspect. Taiwan has been influenced with other countries in the later 1980s. After Wildlife Conservation Law has amended in 1994, the mechanism of public participation has been practicable under law. After many years, some natural protected refuges can’t work on because implemental difficulties and conceptual differences. This study is based on the theory of decentralization of natural conservations. The study methods are (1) Documents analysis method. (2) Interview. (3) Inquire. And I-Land Country Wuwei Harbor Waterbird Refuge is the case study. The analytic objects are (1) the management of Government. (2) Functions of NGOs’. (3) Functions of Community and situations of development. To seek for jointly natural conservation manner between the government and the public.

Abstract:
Decision-making is a very critical aspect of management in the schooling environment. The purpose of this chapter was to investigate the role of primary school principals in engaging role players (particularly teachers) in decision-making in South Africa. Before the democratic dispensation in South Africa, decision-making was predominantly top down. This means that school leadership and principals in particular, made most decisions on their own and teachers were expected to implement these decisions without asking questions. The current study was conducted in the Waterberg Education Department, which is one of the education districts in South Africa. A descriptive research method was used and one hundred and seventy questionnaires were administered to teachers. The study revealed that the majority of principals do promote shared decision-making. This is demonstrated by the fact that the findings further indicate that principals create opportunities for decision-making, they provide feedback and expect engagement of the feedback and allow the views of stakeholders in the work allocation process.

Abstract:
This report presents the results of a long-term trend analyses of seasonal bird community data from a monitoring effort conducted on the Craney Island Dredged Material Management Area (CIDMMA) from 2008 to 2020, Portsmouth, VA. The USACE Richmond District collaborated with the College of William and Mary and the Coastal Virginia Wildlife Observatory, Waterbird Team, to conduct year-round semimonthly area counts of the CIDMMA to examine species presence and population changes overtime. This effort provides information on the importance of the area to numerous bird species and bird species’ groups and provides an index to those species and group showing significant changes in populations during the monitoring period. We identified those species regionally identified as Highest, High, and Moderate Priority Species based on their status as rare, sensitive, or in need of conservation attention as identified by the Atlantic Coast Joint Venture (ACJV), Bird Conservation Region (BCR), New England/Mid-Atlantic Bird Conservation Area (BCR 30). Of 134 ranked priority species in the region, the CIDMMA supported 102 of 134 (76%) recognized in the BCR, including 16 of 19 (84%) of Highest priority ranked species, 47 of 60 (78.3%) of High priority species, and 39 of 55 (71%) of Moderate priority species for BCR 30. All bird count and species richness data collected were fitted to a negative binomial (mean abundance) or Poisson distribution (mean species richness) and a total of 271 species and over 1.5 million birds were detected during the monitoring period. Most all bird species and species groups showed stable or increasing trends during the monitoring period. These results indicate that the CIDMMA is an important site that supports numerous avian species of local and regional conservation concern throughout the year.
