In Situ and Ex Situ Conservation of Chinese Plants

2020
In total, 28,385 higher plants were distributed in the nature reserves, accounting for 77.0% of the total number of higher plants in China. Among them, there are 3842 species which are effectively protected; 2478 species are better protected. More than 84.4% endangered species grow in national and/or provincial natural reserves.

Ex Situ Conservation

2019
This chapter focuses on ex situ (off-site) conservation, which is the protection and management of biodiversity in artificial, human-built environments. Indeed, ex situ conservation allows wild-caught individuals to be maintained under close human supervision in facilities like zoos, aquariums, botanical gardens, or arboretums.

Conservation and Change: A Comparison of In situ and Ex situ Conservation of Jala Maize Germplasm

Crop Science, 2006
Conservation of agricultural genetic resources, whether in situ (in farmers' fields) or ex situ (in a germplasm repository), provides variation for breeding and selection efforts. In this study, we assayed levels of genetic diversity from in situ and ex situ populations of Jala, a very tall, large‐eared race of maize (Zea mays L. subsp. mays), using 22

Effects of a Proposed Ex Situ Conservation Program on In Situ Conservation of the Babirusa, an Endangered Suid

Conservation Biology, 2000
Abstract: Detailed data are rarely available to show how interventions such as captive breeding programs can create an uncontrolled demand for live specimens of endangered species. We present a case study of the effect of a planned, internationally recognized captive breeding program on trade in the endangered ...

Conservation: in situ and ex situ contributions

2002
Komodo dragons, with their large size, predatory nature, and septic saliva, are unique animals that arouse public attention. In situ, they provide an opportunity for ecotourism development and can facilitate fundraising for creating and maintaining protected areas.

Ethiopian in situ conservation

2000
The Ethiopian region is characterized by a wide range of agroclimatic conditions that account for the enormous diversity of its biological resources. Probably the most important of these is the country’s various crop plants that farmers have adapted over centuries of selection and maintenance under various agro-ecosystems. Ethiopia is often referred to

Zoological Parks and the Conservation of Biological Diversity: Linking ex situ and in situ Conservation Efforts

The Journal of Environment & Development, 1995
Linking in situ and ex situ conservation activities represents a major opportunity in the effort to conserve global biological diversity. Zoological parks, aquaria, botanical parks and similar institutions are evolving into conservation-oriented institutions that increasingly contribute to the global conservation strategy embodied in the Convention on ...

The Future of Ex Situ Conservation

2000
It is with great trepidation that we attempt in this final chapter to address what we believe may be the major issues that Ex Situ conservationists will be forced to confront and attempt to resolve in the next ten to fifty years, let alone the whole of the new millennium.
