- Biodiversity management strategies and Policies
- Total protection
- strategy
- areas fenced off from people
- variety of sustainable strategies
- eg ecotourism
- Example
- Costa Rica- montrevrde cloud forest reserve
- deforestation has restricted wildlife to certain fragments of the forest
- project called the Mesoamerican Biological corridor
- This corridor has 7% of the worlds terrestrial species
- conservationists are planting strips of forest to reconnect the remaining fragments
- government has also encouraged ecotourism
- eg the creation of the canopy walkway though a small part of the monteverde reserve
- $45 to clib the canopy
- earn money while keeping the forest protected
- $45 to clib the canopy
- eg the creation of the canopy walkway though a small part of the monteverde reserve
- Costa Rica- montrevrde cloud forest reserve
- positives
- conservation is successful because social, cultural, political and economical factors are taken in
- influences ecotourism
- preserve species that are important for scientific research and medical advancements
- disadvantages
- conflict in poor countries where citizens are cut off from resources
- conservation schemes are based on political boundaries not natural boarders
- outside agencies coordinate these schemes and don't always take into consideration needs of locals
- strategy
- Biosphere reserves
- strategy
- uses principle of zoning to protect core ecological areas
- still allows some social and economic development
- education is vital
- usually have scientific research and monitoring activities as well
- positives
- protects biodiversity and especially endemic species
- more opportunities for scientific research
- Charles Darwin foundation
- tries to resolve conflict between different players
- negatives
- decisions are made slowly due to many different players
- some ecosystem degradation takes place
- pollution, tourism and climate change are still threatening Galapagos
- examples
- Galapagos
- fishing bans we introduced to allow aqua life to recover and increase in their populations
- as this was successful fishing quotas have been put in place
- tourist tax
- ensures their isn't a surplus of tourists
- can be spent on conservation eg replanting
- fishing bans we introduced to allow aqua life to recover and increase in their populations
- Galapagos
- strategy
- Conservation
- In-situ
- conservation in the species natural habitat
- ex-situ
- conservation where species is taken out of natural habitat
- captive breeding, zoos, biodiversity banks
- conservation where species is taken out of natural habitat
- example
- The Millennium seed bank
- conserves seeds as an insurance against the risk of extinction
- banked 13% of the worlds wild plant species
- working with 80 partner countries
- by 2025 they wish to conserve 25% of the worlds plant species
- The Millennium seed bank
- positives
- stops plants becoming extinct
- plants have the potential to provide scientific and medical research in the future
- helps to increase global food security
- negatives
- releasing endangered species into the wild via captive breeding is problematic
- zoos are unnatural and provide stress for the animal
- provide more protection for iconic species rather than keystone species
- species also rely on habitats for survival
- £56 million needed a year to run seed bank
- technology increase carbon pollution
- In-situ
- Restoration
- river Thames
- tighter regulation of polluting from industry
- restoration of the river by cleaning up the land
- re-planting lost habitats
- positive
- 125 types of species
- salmon, otter and sea trout returning
- increase of tourism
- provides more recreational and cultural services
- increase in house prices
- 125 types of species
- over 300 habitat enhancement projects
- negatives
- £1.5 million to clean up 24 km of river and 70km was cleaned
- highly skilled workers needed, labour intensive
- species might be threatened by climate change and invasive species in the future
- maintenance costs needed in the future
- river Thames
- Total protection
