Abstract:

Studies on distribution dynamics of waterbirds and the relation with hydrological changes are essential components of ecological researches. East Dongting Lake is a Ramsar site and especially important wintering ground for herbivorous geese along the East Asian-Australasian Flyway. In this paper, based on annual (2008/09–2016/17) waterbird census data, we investigated the spatial-temporal distributions of three herbivorous goose species (Lesser White-fronted Goose Anser erythropus, Bean Goose Anser fabalis, and Greater White-fronted Goose Anser albifrons) within East Dongting Lake, and analyzed their distribution dynamics (denoted by percentage similarity index, PSI) relative to variations in hydrological regime. The results demonstrated that the distribution of the globally vulnerable Lesser White-fronted Geese changed obviously between years, whereas that of Bean Geese was more stable. Greater White-fronted Geese suffered drastic distribution variation during the study period. The PSI of Lesser White-fronted Geese was negatively correlated with between-year difference in water recession time and mean water level in October, whereas no obvious trend was found in Bean Geese. The Normalized Difference Vegetation Index (NDVI) was applied to detect changes in food resources of the geese, and significant correlations were also found between NDVI and hydrological factors. It was inferred that the variations in hydrological regime affected the annual distribution dynamics of LesserWhite-fronted Geese by changing food conditions; whereas the effect on Bean Geese were not reflected in this study. Species traits may explain the differences in distribution dynamics among the three goose species. It was speculated that Lesser Whitefronted Geese might be more sensitive to habitat change, whereas Bean Geese were more resilient. We suggested that regulating hydrological regime was crucial in management works. Our study could offer scientific information for species conservation in the context of habitat changes in East Dongting Lake wetland and provide potential insights into habitat management in this area.

Abstract:

This report is an external evaluation of the current Swedish Action Plan for the Lesser White-Fronted Goose (2011-2015, extended until 2017) and parts of the Lesser White-Fronted Goose Project, commissioned by the Swedish Environmental Protection Agency (SEPA). The evaluation has come to the following conclusions: 1. The Lesser White-fronted Goose in Sweden is critically endangered and immigration from other populations, like the small Norwegian population, is not very probable. To secure the species from becoming extinct in in Sweden, larger resources are required than what is currently available in the system for action plans at SEPA. 2. An increased focus on breeding areas is recommended to obtain more data on predator activity, human disturbance and recruitment of released birds from the breeding program. 3. An increased control of the red fox (Vulpes vulpes) population in the breeding area during late winter, and an evaluation of the optimal ratio of released to wild birds in the population, are two highly prioritized actions. 4. Establishing a systematic monitoring program including quality control will make estimates on population development more reliable. 5. Potential breeding areas, with special emphasize on the extent of grazing fields, should be surveyed in the proximity of the present breeding area to estimate the possibility of natural expansion into new areas. 6. The captive breeding and release is well organized and of high quality. (However, as stressed above, an estimate of the optimal numbers of released birds into the wild should be evaluated.)

Abstract:

Climate change and human activities cause uncertain changes to species biodiversity by altering their habitat. The uncertainty of climate change requires planners to balance the benefit and cost of making conservation plan. Here optimal protection approach for Lesser White-fronted Goose (LWfG) by coupling Modern Portfolio Theory (MPT) and Marxan selection were proposed. MPT was used to provide suggested weights of investment for protected area (PA) and reduce the influence of climatic uncertainty, while Marxan was utilized to choose a series of specific locations for PA. We argued that through combining these two commonly used techniques with the conservation plan, including assets allocation and PA chosing, the efficiency of rare bird's protection would be enhanced. In MPT analyses, the uncertainty of conservation-outcome can be reduced while conservation effort was allocated in Hunan, Jiangxi and Yangtze River delta. In Marxan model, the optimal location for habitat restorations based on existing nature reserve was identified. Clear priorities for the location and allocation of assets could be provided based on this research, and it could help decision makers to build conservation strategy for LWfG.
