Results of 20 years Bukhara deer restoration.

DSG Newsletter 33: 43-48. ISSN 2312-4644.


The Bukhara deer was previously considered as one of the vulnerable red deer subspecies of Cervus elaphus bactrianus. Due to a nomenclature change (IUCN Red List revision) it is now considered to be one of the three subspecies of Cervus hanglu, i.e. C.h.bactrianus. From 2000 to 2002 it had been under a real threat of extinction. It numbered no more than 350 animals in total in all 10 populations throughout its range in Central Asia, and was completely extinct in the most important part of its historical area. In accordance with the MOU and Action Plan on Bukhara deer conservation and restoration (CMS), signed in 2002, and in the frame of WWF projects since 1999, a set of important activities ensured population growth in natural habitats, natural habitat restoration and reintroduction in suitable sites within the historical area.

The implemented activities resulted in significant growth of all populations, which allows the species to be considered as Least Concern.

Outcomes and lessons from a quarter of a century of Sand lizard Lacerta agilis reintroductions in southern England.

Int. Zoo Yearb. 51: 87-96.

Volltext (PDF)


Despite occurring widely across Europe and Asia, the Sand lizard Lacerta agilis is threatened in the north-western part of its range and had disappeared from much of its former habitat in England and Wales prior to concerted conservation action. A breeding population established at Marwell Zoo, UK, contributed to the re-establishment of 26 populations of Sand lizards at heathland and coastal dune sites across southern England as part of a wider multi-stakeholder response to reverse the decline of the species. Knowledge about the biology of Sand lizards was accrued during the process, which helped to refine the management of the breeding population that was maintained in a naturalistic setting within the indigenous range of the species. These successes were underpinned by coordinated collaborative actions and long-term institutional commitments against a backdrop of considerable change in the statutory framework governing Sand lizard conservation. The management of this project was not without cost or risk, including protection of valuable founder stock, incomplete knowledge about the health and disease status of Sand lizards, intrinsic constraints of limited founder representation, and the challenges of monitoring this elusive species post release.

HAVELKA, P. (1995)

Auswilderung, Gefangenschaftsvermehrung und Erhaltung bedrohter Tierarten -  eine Aufgabe des Naturschutzes.

Carolinea, Beiheft 9.
Staatl. Mus. f. Naturkde. Karlsruhe & Naturwiss. Ver. Karlsruhe e.V

Die historische Zeit ist gekennzeichnet durch einen zunehmenden Verlust der vom Men­schen unbeeinflussten Lebensräume. Insbesondere in den letzten hundert Jahren wird dies von einer bisher unbekannten Form des Verlustes an Tier- und Pflanzenarten lokal und weltweit begleitet. Diesen Trend zu stoppen ist das Anliegen vieler. Die Erhaltung und der Schutz der natürlichen Lebensräume ist dabei die Basis für ein langfristiges Hilfskonzept. Oft ist dies jedoch nicht einfach und es stellt sich die Frage, ob es wünschenswert ist, im Ausgleich für den Verlust an natürlichen Lebensräumen künstliche Biotope bereitzustellen. Die Schlagworte „Natur aus zweiter Hand“ sind wohl allen bestens bekannt.

New observations of the ‘extinct’ Barbary sheep Ammotragus lervia ornata in Egypt.

Oryx 36 (3): 301-304.


The Barbary sheep or aoudad Ammotragus lervia is widely distributed in the mountains of the Sahara and North Africa. The 2000 IUCN Red List assessment of the Egyptian subspecies A. l. ornata categorized this taxon as Extinct in the Wild. We present new evidence, collected during 1997–2000, that this subspecies is extant in both the extreme south-east and south-west of Egypt, and reassess the status of captive aoudad in Egypt. We recommend that the category of A. l. ornata on the IUCN Red List be changed to Critically Endangered, that conservation of wild aoudad in Egypt be prioritized, and that the subspecific status of both the wild and be reassessed.

BAXTER, R. P. H. (2015)

Movement and activity drivers of an ecosystem engineer: Aldabrachelys gigantea on Aldabra Atoll.

UWW262 Environmental Science Master Thesis. Institute of Evolutionary Biology and Environmental Studies.
62 Seiten, 16 Abbildungen, 118 Referenzen


The findings of my study suggest that temperature and rainfall are key factors
influencing the movement of tortoises, with movement being restricted by daily activity rate
and seasonal fluctuations in vital resources. In the context of climate change it is important that
monitoring of movement patterns and home range sizes continues long-term for such a long-
lived species, in order to identify the magnitude of any change. Tortoises will be able to adapt at
the individual level, but if climate change is severe the population level will certainly decrease,
which would have dramatic consequences for the atoll ecosystem. As the chief engineers,
tortoises are tied directly to their habitat, which in turn requires the tortoises in order to
maintain diversity and heterogeneity.

My study, in conjunction with previous studies from the Royal Society days, can help to
characterise movement of tortoises on the atoll at a population level. The behavioural norm has
yet to be resolved, but the factors which determine apparently random movement in each
individual are beginning to be understood. As the primary herbivore on Aldabra, tortoises in
their large numbers exert considerable pressure on their habitat. With further reseearch we?
can hopefully extrapolate the findings in this thesis of individual tortoise movement ecology to
the population level.

Mounting evidence demonstrates that global climate is changing, and conservation
biologists not only need to anticipate the phenology and movements of individual species in
response to climate change (Root and Schneider 2006), but must also be able to project and
predict the impact of potential changes to biological communities such as Aldabra. Direct and
indirect effects of global climate change are difficult to quantify in many instances, especially as
the changes are not immediate, and will be more difficult to mitigate against in the short term
for tortoises. By remotely monitoring tortoise movement and activity we now have baseline
data to monitor change in a changing climate and plan effective conservation strategies for the
species, and therefore the atoll.

Thick-billed Parrot (Rhynchopsitta pachyrhyncha) Recovery Plan Addendum.

122 Seiten.

Recovery Strategy:

The thick-billed parrot has been absent from the U.S. for over 70 years and now only occurs in Mexico.  Thus, the focus of recovery conservation actions should occur inMexico.  Since the mid-1990s, conservation organizations and the Mexican government have been implementing conservation actions focused on research, monitoring, and protection of key breeding areas.  Furthermore, as part of a federal initiative, Mexico convened a group of parrot experts and in 2009 published a recovery plan (the PACE) addressing both the maroon-fronted and thick-billed parrots.  The focus of the PACE (CONANP 2009) is on extant populations of the thick-billed parrot; it does not address thick-billed parrot historical records or historical range in the U.S. Therefore, our approach in this Addendum to the PACE is to:

  • Summarize information on thick-billed parrot’s historical occurrence in the U.S.;
  • Synthesize or reference information (when feasible) from the PACE to formulaterecovery planning components as are required by the ESA;
  • Incorporate supplemental information received from Mexico and U.S. partners since publication of the PACE;
  • Identify broad actions necessary to address conservation of the species within its U.S. historical range;
  • Identify partnerships and opportunities to facilitate recovery of extant populations.

Antelope Conservation ä From Diadnosis to Action.

Conservation Science and Practice 16: 1-376.

Wiley Blackwell / Zoological Society of London. ISBN: 978-1-118-40957-2.


Antelopes constitute a fundamental part of ecosystems throughout Africa and Asia where they act as habitat architects, dispersers of seeds, and prey for large carnivores. The fascication they hold in the human mind is evident from prehistoric rock paintings and ancient Egyptian art to today's wildlife documentaries and popularity in zoos. In recent years, however, the spectacular herds of the past have been decimated or extripated over wide areas in the wilds, and urgent conservation action is needed to preserve this world heritage for generations to come.

As the first book dedicated to antelope conservation, this volume sets out to diagnose the causes of the drastic declines in antelope biodiversity and on this basis identify the most effective points of action. In doing so, the book covers central issues in the current conservation debate, especially related to the management of overexploitation, habitat fragmentation, disease transmission, climate change, populations genetics, and reintroductions. The contributions are authored by world-leading experts in the field, and the book is a useful resource to conservation scientists and practitioners, researchers, and students in related disciplines as well as interested lay people.

Giraffenschutz in Uganda

Schutz der Rothschildgiraffe im Kidepo Nationalpark

Zoo und Zoostiftung Berlin

AFR 2016 4 rothschild kidepo
Rothschildgiraffen im Kidepo Nationalpark © Care for Karamoja
Die bedrohte Rothschildgiraffe (Giraffa camelopardalis rothschildi) ist natürlicherweise weltweit nur noch in zwei Verbreitungsgebieten zu finden: Im Murchison Falls Nationalpark sowie im Kidepo Valley Nationalpark (beide Uganda). Während die mit etwa 1.000 Tieren deutlich größere Population im Murchison Falls Nationalpark teils von einer bislang nicht genauer untersuchten Hautkrankheit befallen ist, ist die Population im Kidepo Nationalpark unbelastet und daher von besonderer Wichtigkeit. Das Projekt „Care for Karamoja“, das vom Zoo Santa Barbara (USA) ins Leben gerufen wurde, hat es sich zur Aufgabe gemacht, diese sehr kleine Population von ca. 54 Tieren zu schützen.

Da der Kidepo-Nationalpark im Norden an den politisch extrem instabilen und von Armut gekennzeichneten Südsudan grenzt ist der Hauptbedrohungsfaktor für diese kleine Population die illegale Jagd für die Gewinnung von Fleisch und Fellen. Außerhalb des Parks gibt es wegen der dichten Besiedlung und intensiven Landnutzung keine Giraffen - und kaum anderes Großwild - mehr. Daher wurde mit der Uganda Wildlife Authority sowie dem Uganda Wildlife Education Centre (UWEC) ein Schutzprogramm erarbeitet. Dies beinhaltet in erster Linie die Unterstützung der Ranger im Kidepo NP, die dringend mit professionellem Equipment ausgestattet werden müssen. Weiterhin soll die lokale Bevölkerung langfristig für den Artenschutz sensibilisiert werden, indem u.a. lokalen Schulklassen der Besuch des Nationalparks ermöglicht wird. Der Zoo Berlin hält Rothschildgiraffen und unterstützt als größter europäischer Partner dieses Schutzprojekt, zu dem auch Zoos in den USA beitragen.

Conservation breeding of the Northern river terrapin Batagur baska at the Vienna Zoo, Austria, and in Bangladesh.

International Zoo Yearbook 49: 39–41. London Zoological Society. ISSN 0074-9664. DOI: 10.1111/izy.12070.


Wild populations of the Northern river terrapin Batagur baska have been decimated to such an extent that the species can be considered as ecologically extinct. Harvesting and habitat reduction are the main reasons for the drastic demise of B. baska, which formerly inhabited rivers and estuaries in East India, Bangladesh and Myanmar. A cooperative in situ and ex situ conservation project was established to secure the survival of this large river terrapin. In 2010, at Vienna Zoo, Austria, the first two captive-bred juveniles of the project hatched and presented an opportunity to call attention to this Critically Endangered species. With combined efforts a breeding population has been assembled in Bangladesh's Bhawal National Park and 84 juveniles have been reared in the past 2 years. Project-Batagur demonstrates how zoos can play a key role in sustainable long-term conservation of threatened species.
