The conservation status of the Blue-throated Macaw Ara glaucogularis, a Bolivian endemic, is assessed using the most recent information available. The known range of the species is patchily distributed within an 8,600 km2 area of lowland savanna–forest habitat in the Beni department, under private ownership for cattle ranching, which is the main form of land use in the region. Population surveys of the Blue-throated Macaw revealed this species to exist in very low numbers. The immediate threat to the species is illegal trapping for the live bird trade. Effects of cattle grazing and savanna burning may modify habitat characteristics, but there is no direct evidence suggesting that these factors negatively influence the ecological requirements of Ara glaucogularis. The species is highly associated with the Attalea phalerata palm, which it uses for feeding and nesting. Current conservation efforts include: population and distribution surveys and assessment of habitat requirements; environmental awareness targeted at landowners and ranch personnel; collaboration with subnational and central government bodies; and development of strategies to curtail parrot trafficking activities. Recommendations for the long-term conservation of the species include increasing the involvement of landowners to strengthen protection for wild macaws; working with the Bolivian government on strategies to curb macaw trafficking; increasing environmental education activities with local inhabitants; basic research on breeding requirements and limitations of wild Blue-throated Macaws; and investigating the application of private reserves to the Blue-throated Macaw range.

Abstract This paper subscribes to the concept of Key Geoheritage Area (KGA) which is currently being developed. Three localities in northeast Brazil are described as possible candidates for KGA. They represent the diversity of erosional granite landscapes found in cratonic areas. Pedra da Boca is an impressive cluster of tall domes rising from the marginal escarpment of Borborema Plateau, with gigantic tafoni. Pai Mateus is located on the Borborema Plateau and consists of a group of low granite elevations (ruware, whalebacks) with residual boulders scattered on their surfaces. These boulders are hollowed out by weathering, providing another very distinctive type of tafoni. Quixadá area is an inselberg landscape, with a few dozens of bedrock hills rising from the plain. Among minor features, karren are ubiquitous. Collectively, these three sites show different types of cratonic granite scenery, a multitude of medium-size and minor geomorphic features, and illustrate pathways for inselberg formation and decay through long-term weathering and erosion. Therefore, they are considered to fit the concept of KGA. In addition, each landscape has considerable aesthetic and scenic values, with great potential for geotourism and geoeducation. Nevertheless, their current conservation status is low and geointerpretation nearly nonexistent and these challenges are to be addressed in the future.

The Status

SummaryFour weeks of fieldwork in the forests of Mindoro, Philippines, in 1991 has elucidated the status of the six bird species endemic to the island. Of these, Ducula mindorensis and Otus mindorensis are high-altitude species with restricted ranges and in need of active conservation in the medium term. Three of the four lowland species, Gallicolumba platenae, Centropus steerü and Penelopides mindorensis are under immediate threat of extinction through forest clearance and fragmentation, while the fourth, Dicaeum retrocinctum, s i not under immediate threat but is certainly at risk of extinction in the long term. Whilst deforestation is an enormous problem across the entire Philippines, Mindoro is the smallest centre of endemism with the least forest cover after the Sulu Islands. Extinctions are believed inevitable within the next 10 years unless concerted action is urgently taken. The Halcon range must receive attention in order to conserve the montane species, but more urgent by far is the preservation of lowland forest remnants, concentrating on central-west Mindoro.

Phaseolus Species

Rare and endemic plants, such as the wild species of Phaseolus (Fabaceae) in northeastern Mexico, deserve high priority in conservation efforts because of their uniqueness and usefulness as plant genetic resource. This is particularly important because during the last decades, some of these species have become endangered because of anthropogenic and natural factors. The study aimed to determine the current conservation status of 11 reported wild bean species in northeastern Mexico, using wild bean data from 77 expeditions to the states of Nuevo León and Tamaulipas during the period 1869-2013.The conservation status of the different species was determined according to the Official Mexican Standard NOM-059-SEMARNAT-2010. The categories of risk were based on four indicators: amplitude of distribution, habitat status, biological vulnerability and impact of human activity. The following eight wild Phaseolus species are not at risk of extinction: P. albiflorus, P. glabellus, P. leptostachyus, P. maculatifolius, P. neglectus, P. pedicellatus, P. vulgaris and P. zimapanensis. On the other hand, P. altimontanus Freytag & Debouck is categorized as threatened; P. novoleonensis Debouck, in danger of extinction; and P. plagiocylix Harms, possibly extinct.  Current in situ and ex situ conservation programs need to be strengthened and expanded for the medium- and long-term protection of wild bean species in northeastern Mexico.

The Impact

Amphibians are among the most threatened groups of animals on earth. In part due to their highly permeable skin, amphibians are highly sensitive to environmental changes and pollution and provide an early-warning system of deteriorating environmental conditions. The more we learn about the impact of environmental changes on amphibians, the better we as humans will be able to arrest their demise, and our own. Status of Conservation and Decline of Amphibians brings together the current knowledge on the status of the unique frogs of Australia, New Zealand, and the Pacific. Although geographically proximate, each region presents unique challenges and opportunities in amphibian research and conservation. This book contributes to an understanding of the current conservation status of the amphibians of each region, aims to stimulate research into halting amphibian declines, and provides a better foundation for making conservation decisions. It is an invaluable reference for environmental and governmental agencies, researchers, policy-makers involved with biodiversity conservation, and the interested public.

Abstract We have a poor understanding of the ecology of many African small mammals due to a lack of basic research. This has important conservation implications, particularly for range-restricted species in tropical regions. In this study, we provide new insight into the distribution and ecology of one such species, the Nimba otter-shrew (Micropotamogale lamottei Heim de Balsac 1954). We apply niche and occupancy modeling to inform on the range and habitat use of this semi-aquatic species. We estimate that its global range [extent of occurrence (EOO)] is 14,725 km2. Using occupancy modeling, we show that mining has a direct impact on the occurrence of this species. We also provide preliminary observations of its movements through radio-tracking. Using maximum entropy (Maxent) modeling, we identify the North Lorma National Forest and the Wonegizi range (northern Liberia) that appear suitable for this species, but where it has not yet been recorded. We suggest that the Nimba otter-shrew has a global distribution centered on the Mount Nimba region, straddling the borders of Liberia, Guinea and Côte d’Ivoire, and that it requires urgent conservation attention to ensure its long-term persistence. Finally, we provide evidence to support an uplisting of its IUCN Red List conservation status to Vulnerable.

AbstractIn 1994 Alan Rabinowitz decried what he regarded as lackadaisical attempts by governments, NGOs and international funding agencies to conserve the Sumatran rhinoceros Dicerorhinus sumatrensis. Sixteen years on it is timely to evaluate whether his warnings were heeded. We review the current conservation status of D. sumatrensis throughout its range and the latest threats and challenges complicating efforts to conserve this species. Recent data from governments, NGOs and researchers indicate that the global population could be as low as 216, a decline from c. 320 estimated in 1995. Based on lessons learnt and expert opinions we call on decision makers to focus on two core strategies for conservation of D. sumatrensis: (1) the translocation of wild individuals from existing small, isolated or threatened forest patches into semi-in situ captive breeding programmes, and (2) a concomitant enhancement of protection and monitoring capacities in priority areas that have established these breeding facilities or have recorded relatively high population estimates and track encounter rates. At least USD 1.2 million is required to implement these strategies annually in four priority areas: Bukit Barisan Selatan and Way Kambas National Parks on Sumatra, and Danum Valley Conservation Area and Tabin Wildlife Reserve on Sabah. Given that conservation funds are rarely secure and D. sumatrensis is still in decline we call on potential donors to help secure and augment existing capacities of organizations in these four priority areas before committing resources to elucidate the status of the species in other areas such as Gunung Leuser and Taman Negara National Parks.

Conservation Actions

The decline of many species towards extinction has largely focused conservation efforts on ensuring that species remain extant. However, conservationists have long recognised the need to complement this by aiming to recover depleted populations throughout a species’ range and to restore species to ecosystems from which they have been extirpated. The main objectives of the IUCN Green Status of Species are: to provide a standardised framework for measuring species recovery; to recognise conservation achievements; to highlight species whose current conservation status is dependent on continued conservation actions; to forecast the expected conservation impact of planned conservation action; and to elevate levels of ambition for long-term species recovery. These objectives together encourage conservation towards species recovery, throughout a species’ range.

The study aimed at determining the status of occurrence of the orchid treasure of Bangladesh for providing data for Planning National Conservation Strategy and Development of Conservation Management. 54 orchid species are assessed to be presumably lost from the flora of Bangladesh due to environmental degradation and ecosystem depletion. The assessment of their status of occurrence was made based on long term field investigation, collection and identification of orchid taxa; examination and identification of herbarium specimens preserved at CAL, E, K, DACB, DUSH, BFRIH,BCSIRH, HCU; and survey of relevant upto date floristic literature. These species had been recorded from the present Bangladesh territory for more than 50 to 100 years ago, since then no further report of occurrence or collection from elsewhere in Bangladesh is available and could not be located to their recorded localities through field investigations. Of these, 29 species were epiphytic in nature and 25 terrestrial. More than 41% of these taxa are economically very important for their potential medicinal and ornamental values. Enumeration of these orchid taxa is provided with updated nomenclature, bangla name(s) and short annotation with data on habitats, phenology, potential values, recorded locality, global distribution conservation status and list of specimens available in different herbaria.J.

The caterpillars of the Southern Swallowtail, Papilio alexanor have been recorded in the vicinity of Trebinje, Bosnia & Herzegovina. This is the first recent observation of this species in the country and the third observation so far. Opopanax chironium is confirmed as the larval host plant in Bosnia and Herzegovina, which was expected due to the recent observations from Croatia. Its status and distribution in the country are still not clear, and further surveys are recommended in order to reconfirm the historical records as well as to assess its current conservation status. Due to the limited extent of its occurrence, we propose to include it in the Red list of fauna of Bosnia & Herzegovina as Vulnerable (VU).
