SummaryThe coast of Bohai Bay, north-western Yellow Sea, is critical for waterbirds migrating along the East Asia-Australasian Flyway. Between 1994 and 2010, a total of 450 km2of offshore area, including 218 km2of intertidal flats (one third of the original tidal area in the bay), has been reclaimed along the bay for two industrial projects. This has caused the northward migrants to become concentrated in an ever smaller remaining area, our core study site. The spring peak numbers of two Red Knot subspecies in the East Asia-Australasian Flyway,Calidris canutus piersmaiandC. c. rogersi, in this so far little affected area increased from 13% in 2007 to 62% in 2010 of the global populations; the spring peak numbers of Curlew SandpiperC. ferrugineaincreased from 3% in 2007 to 23% in 2010 of the flyway population. The decline in the extent of intertidal mudflats also affected Relict GullsLarus relictus, listed by IUCN as ‘Vulnerable’; during normal winters 56% of the global population moved from the wintering habitats that were removed in Tianjin to the relatively intact areas around Tangshan. Densities of wintering Eurasian CurlewNumenius arquata, and spring-staging Broad-billed SandpiperLimicola falcinellusand SanderlingCalidris albahave also increased in the remaining areas. With the proposed continuation of land reclamation in Bohai Bay, we predict waterbird densities in the remaining areas to increase to a point of collapse. To evaluate the future of these fragile, shared international resources, it is vital to promote an immediate conservation action plan for the remaining coastal wetlands in this region, and continued population monitoring to determine the effects of this action.

Tal (mount) Irbid in Irbid city, Jordan, with its continuous human occupation from the Bronze Age until the present, demonstrates the main landmark that has guided the spread of the urban growth of the city. The outcome of studies carried out at Irbid’s historic core, in relation to assessing the loss and degradation of the core’s cultural heritage, shall be analyzed, investigated, and discussed, as also concerns, obstacles, and issues of sustainability to this urban heritage conservation and tourism planning. The paper starts by defining the urban heritage for the historic core, which tends to be set aside, in the city’s rapid development. Actually, the remaining historic buildings can also provide the necessary inter-relationships between the historic core areas and the wider urban context to achieve a sustainable and integrated tourism and conservation action plan for the three heritage neighborhoods around the Tal, while building on tourism opportunities and taking into consideration the needs and the vital role of the local community. The paper concludes that urban heritage conservation and protection of the integrity and identity of the historic core city fabric can assist in its branding, promotion, and management in ways that could enhance the local community belonging, quality of everyday lifestyle, and visitors' experience.

Land reclamation can significantly influence spatial distribution of heavy metals in inshore sediments. In this study, the distribution and contamination of heavy metals (Cd, Cr, Cu, Ni, Pb, and Zn) in inshore sediments of Bohai Bay were investigated after the land reclamation of Caofeidian. The results showed that the concentrations of Cd, Cr, Cu, Ni, Pb, and Zn in the sediments were 0.20–0.65, 27.16–115.70, 11.14–39.00, 17.37–65.90, 15.08–24.06, and 41.64–139.56 mg/kg, respectively. These metal concentrations were generally higher in the area of Caofeidian than in other Chinese bays and estuaries. Spatially, the concentrations of Cd, Cr, Cu, Ni, and Zn were markedly lower in the sediments close to Caofeidian compared with other regions, whereas the concentrations of Pb showed an opposite case. Hydrodynamic conditions after the land reclamation were the major factor influencing the distribution of heavy metals in the sediments. Grain sizes dominated the distribution of Cu and Zn, and organic matters and Fe/Mn oxides/hydroxides also determined the distribution of the heavy metals. Multiple contamination indices showed that the inshore sediments were moderately to highly contaminated by Cd and slightly contaminated by other heavy metals. Similarly, Cd showed a high potential ecorisk in the sediments, and other metals were in the low level. Chromium contributed to higher exposure toxicity than other metals by the toxicity unit and toxic risk index. The results of this study indicate that after the land reclamation of Caofeidian the contamination and ecorisk of heavy metals in the sediments markedly decreased in the stronger hydrodynamic areas.

Gavialis Gangeticus

Gharial (Gavialis gangeticus), biological treasure of the Indian subcontinent now restricts its existence in few big river systems of India and Nepal only. Innumerable threats posed to Gharial and its natural habitat led to extinction of the species from Bhutan, Burma and Pakistan and almost extinct from Bangladesh. Despite of the concerted Gharial conservation effort of Nepal and India since midtwentieth century, the species finds its status as Critically Endangered on the IUCN 2007 Red list. Realizing the fact that a basic step in any conservation plan involving mega herpetofauna is to estimate its population status and structure and its geographic distribution, Department of National Parks and Wildlife Conservation (DNPWC) and World Wildlife Fund (WWF) Nepal held Gharial census on January-February 2008. The census estimated a total of 81 Gharials in Nepal. Out of total Gharial recorded during the census, 70 Gharials were recorded through direct sighting while 11 were based on indirect observations. Factors responsible for decreasing Gharial population were flood and dam construction, habitat destruction and decline in food quality & quantity. Over fishing, use of gill nets and river poisoning adversely affected the quality and quantity of fishes that serve as main food for Gharial. Contradictory to the past findings decreasing Gharial population was not attributed to the illegal egg collection and poaching of male Gharial for "Ghara". Deliberate killing was only found to take place in case the animal got entrapped in fishing nets. We conclude that Gharial should receive high conservation priority in future too. Efforts to restore the population through artificial breeding have much to do for maintaining present population. However, declining population, despite of several Gharial releases, should be addressed through more detailed scientific study. Census should be based on direct sighting through extensive field observation. Gharial release should precede scientific field study for assessing habitat suitability and follow with intensive monitoring program. The emphasis should be given for preparing specific Gharial Conservation Action Plan for regulating conservation activities to help conserve Gharial in Nepal.

In a recent study, O'Brien et al. (1998a) sought to provide a better understanding of the distribution and status of the Bornean Peacock-pheasant Polyplectron schleiermacheri in Central Kalimantan, Indonesia, based on an analysis of questionnaires and semi-structured interviews with local inhabitants. This was the first scientific contribution concerning this species after the launch of the Conservation Action Plan for Pheasants (McGowan and Garson 1995). Although the authors of this study acknowledged and discussed the limitations of the questionnaire approach and some of the anomalies in the replies they received, we still feel that the questions posed in this survey may have been phrased in such a way as to invite slight biases in the answers, and that some of the analyses of the replies may have created further biases. We therefore feel it may be helpful to review these uncertain areas in order to help improve questionnaire surveys in future fieldwork. Two of us (I.S. and A.P.S.) helped conduct the surveys in question, and all of us have experience of galliforms in Kalimantan.We occasionally refer to additional information concerning the survey which was presented in another publication (O'Brien et al. 1998b).

Green Peafowl

SummaryThe Green Peafowl has undergone a substantial decline throughout East Asia since the turn of the century and is now reported only from a few widely scattered localities in several countries. Its plight was highlighted in the IUCN Pheasant Action Plan where it was one of the highest priorities for conservation action. Recent surveys have clarified its status and distribution in at least part of several range countries and there is patchy information from elsewhere in its range. The current knowledge of the species was reviewed at a workshop in Malaysia in autumn 1997 at which representatives from most key countries were present. The species is extinct in Peninsular Malaysia, and almost lost from Bangladesh and north-east India. There is one large population remaining in Thailand and the species is thought to be in danger of extinction in Laos. China and Indonesia hold mostly small and scattered populations although the latter does contain two large protected populations. The status in Myanmar and Cambodia is unknown, although the presence of large tracts of apparently suitable habitat in eastern Cambodia suggest that this area may hold the largest populations of the species. Conservation recommendations fall into four categories: a strategic review, assessing status and understanding ecological requirements, investigating the human-Green Peafowl relationship and considering the possibility of reintroducing the species where appropriate.
