Abstract:
Migratory birds breeding at high latitudes face challenges in relation to timing of breeding vs. annual weather, climate change, and predator abundance. Hunting pressure along migration routes and wintering quarters forms an additional challenge.We studied population structure and interaction with environmental factors in a small population of threatened Lesser White-fronted Geese Anser erythropus, living in sub-arctic zone in Lapland in 1989–1996. Thereafter the population disappeared. The population comprised 2–15 breeding pairs plus 0–12 non-breeders, which left in June to moult elsewhere. 30 broods were observed (0–8 annually) with an average number of 2.9 goslings. Of the 3 satellite tagged plus 7 ringed geese at least 3were shot and altogether 4 killed during the first year. Only 2 were seen alive next year or later. Laying started on average 4 June (21May – 13 June) and hatching took place 2 July (21 June–10 July) with an intra-seasonal clutch size decline. Variation in nesting initiation was not explained by local phenology, but instead by the date of staging peak in the last pre-breeding staging area 600 km south. Reproduction was affected negatively by cold spells and positively by the sum of daily effective temperatures by 5 July. Vole populations were low and a real cycle missing. No effect of reindeer abundance or human presence on reproduction could be found.

Abstract:
The analysis of the photographs sent by the hunters from Sytomino village, Khanty-Mansiysk Autonomous Okrug – Ugra, together with the further survey detected the place of migration stops of Lesser White-fronted Geese in the Middle Ob valley. The birds were staying at the small lake 3.5 km east of the village. On September 12, 2011, one wounded individual was found near the lake at the complex raised bog 9.5 km southwest of the city of Lyantor. Several ways can be suggested by us to save flying Lesser Whitefronted Geese and other species of vulnerable animals at the territory of the autonomous okrug. This will include the following measures to take: an obligatory exam for hunters to be able to identify some species of the regional fauna; large penalties for illegal hunting, more active propaganda of respect for nature and educational work and developing hunting culture. The article also covers economic and organizational issues.

Abstract:
The global population of Anser erythropus has rapidly declined since the middle of the 20th century. The decline in numbers has been accompanied by the fragmentation of the breeding range and is considered as «continuing affecting all populations, giving rise to fears that the species may go extinct». Overhunting, poaching and habitat loss are considered to be the main threats. The official estimate of the dimension of the decline is in the range of 30% to 49% between 1998 and 2008. Monitoring and the prospection of new areas are needed for the future conservation of this species. The eastern part of the Nenetsky Autonomous Okrug, the Baydaratskaya Bay and the Lower Ob (Dvuobye) are important territories for the Western main population of Anser erythropus on a flyway scale. Moving along the coast to the east, Anser erythropus can stay for a long time on the Barents Sea Coast, from where they fly over the Baydaratskaya Bay to the Dvuobye. We made aerial surveys and identified key sites and the main threats for Anser erythropus on this part of the flyway. According to our data, the numbers of the Western main population of Anser erythropus amount to 48 580 ± 2820 individuals after the breeding season, i.e. higher than the previous estimates made in autumn in Northern Kazakhstan. The key sites of Anser erythropus in this part of the flyway were identified.

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.
