What is in situ conservation?
In situ conservation involves protecting species in their natural habitats, ensuring their survival by preserving both the species and their ecosystem.
What are the methods of in situ conservation?
Methods include establishing protected areas (national parks, wildlife reserves), controlling invasive species, protecting habitats, promoting species through food/nesting site protection, and giving legal protection to endangered species.
Why is in situ conservation important?
It preserves species within their natural habitat, allowing larger populations to be protected with less disruption than removal. Recovery chances are higher compared to ex situ conservation.
What is the challenge of in situ conservation?
Challenges include controlling external threats like poaching, predators, disease, and climate change, which can still threaten species even within protected areas.
What is ex situ conservation?
Ex situ conservation involves protecting species by removing part of the population from a threatened habitat and placing them in a safer location, often as a last resort.
What are methods of ex situ conservation?
Methods include relocating organisms to safer areas, captive breeding and reintroduction, botanic gardens for rare plants, and seed banks for storing seeds for future use.
What are the advantages of ex situ conservation?
Advantages include protection from predation and hunting, the ability to manage the environment, and breeding in controlled environments to strengthen populations.
What are the disadvantages of ex situ conservation?
Disadvantages include limited capacity for individuals, difficulty and expense of maintaining suitable environments, and potential for habituated animals to lose natural behaviors or contract diseases.
Which type of conservation (in situ or ex situ) is usually more successful?
In situ conservation is usually more successful as it preserves both the species and their natural habitat, whereas ex situ conservation often faces challenges in breeding and adapting species to new environments.
What is the Rio Convention on Biological Diversity (CBD)?
The CBD aims to develop international strategies for biodiversity conservation and the sustainable use of animal and plant resources. It makes biodiversity conservation everyone’s responsibility and guides governments on how to conserve it.
What is the purpose of the CBD?
The purpose of the CBD is to provide international strategies for biodiversity conservation, promote sustainable use of resources, and guide governments on conservation methods.
What is the CITES Agreement?
The CITES (Convention on International Trade in Endangered Species) is an agreement aimed at regulating the international trade of wild animal and plant specimens to prevent endangerment due to trade.
How does CITES help conserve species?
CITES helps conserve species by making it illegal to kill endangered species, regulating trade through licensing, and prohibiting the trade in products made from endangered species (e.g., rhino ivory).
Why is international cooperation important in species conservation?
International cooperation is important because issues like poaching and illegal trade in endangered species cannot be solved by one country alone. Cooperation ensures that conservation efforts are global and effective.
What is the Countryside Stewardship Scheme (CSS)?
The CSS is a UK scheme introduced in 1991 to conserve wildlife, improve biodiversity, and enhance habitats by offering payments to landowners who implement specific conservation techniques.
What are some goals of the Countryside Stewardship Scheme?
Goals include conserving wildlife, improving and extending wildlife habitats, regenerating hedgerows, creating grassy margins around fields, and grazing upland areas to control bracken.
How does the Countryside Stewardship Scheme benefit wildlife?
The scheme has led to the recovery of species such as the stone curlew, black grouse, and bittern by encouraging habitat regeneration and better land management practices.
How many agreements were made under the Countryside Stewardship Scheme by the year 2000?
By the year 2000, there were 10,000 agreements in England under the Countryside Stewardship Scheme.
