An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of ...

Faculty Scholarship

Recent genetic analysis has shown that the extinct Caspian Tiger (P. t. virgata) and the living Amur Tigers (P. t. altaica) of the Russian Far East are actually taxonomically synonymous and that Caspian and Amur groups historically formed a single population, only becoming separated within the last 200 years by human agency. A major conservation implication of this finding is that tigers of Amur stock might be reintroduced, not only back into the Koreas and China as is now proposed, but also through vast areas of Central Asia where the Caspian tiger once lived. However, under the current tiger conservation ...

Tackling Biocomplexity With Meta-Models For Species Risk Assessment, Philip J. Nyhus, Robert C. Lacy, Francis R. Westley, Philip S. Miller, Harrie Harrie Vredenburg, Paul C. Paquet, John Pollak Jan 2007

Tackling Biocomplexity With Meta-Models For Species Risk Assessment, Philip J. Nyhus, Robert C. Lacy, Francis R. Westley, Philip S. Miller, Harrie Harrie Vredenburg, Paul C. Paquet, John Pollak

Faculty Scholarship

We describe results of a multi-year effort to strengthen consideration of the human dimension into endangered species risk assessments and to strengthen research capacity to understand biodiversity risk assessment in the context of coupled human-natural systems. A core group of social and biological scientists have worked with a network of more than 50 individuals from four countries to develop a conceptual framework illustrating how human-mediated processes influence biological systems and to develop tools to gather, translate, and incorporate these data into existing simulation models. A central theme of our research focused on (1) the difficulties often encountered in identifying and ...

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson Jan 2004

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Faculty Scholarship

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife ...

Wildlife Knowledge Among Migrants In Southern Sumatra, Indonesia: Implications For Conservation, Philip J. Nyhus, Sumianto Tilson, Ronald Tilson Jan 2003

Wildlife Knowledge Among Migrants In Southern Sumatra, Indonesia: Implications For Conservation, Philip J. Nyhus, Sumianto Tilson, Ronald Tilson

Philip J. Nyhus

The value of traditional ecological knowledge for biodiversity research and conservation is widely recognized. The value of wildlife knowledge provided by recent migrants is less clear. Photographs of 10 mammal species were shown to 622 individuals in communities near Way Kambas National Park in Sumatra, Indonesia, to assess wildlife knowledge among recent migrants and to identify socio-economic variables that can be used to identify more knowledgeable informants. Knowledge scores were categorized by taxonomic family, genus and species. Large, charismatic and abundant animals were identified more frequently than smaller and more secretive animals. Higher knowledge scores were significantly associated with males ...

A Role For Natural Resource Social Science In Biodiversity Risk Assessment, Philip J. Nyhus, Frances R. Westley, Robert C. Lacey, Philip S. Miller Jan 2002

A Role For Natural Resource Social Science In Biodiversity Risk Assessment, Philip J. Nyhus, Frances R. Westley, Robert C. Lacey, Philip S. Miller

Faculty Scholarship

Biologists have made considerable progress in developing realistic simulation models to predict extinction risks for threatened species. Social scientists have to date had a more limited role in these efforts. This limited involvement comes despite the growing acknowledgment by population biologists and simulation modelers that this additional input is necessary for these models to accurately reflect the impact of humans and human-dominated landscapes on wildlife populations. We argue that collaborations among social and biological scientists can provide unparalleled opportunities to develop new conceptual and simulation tools for biodiversity risk assessment. One challenge is that while the value of interdisciplinary research ...
