Protecting nature: different views and strategies
Big picture: Conservation and regeneration aim to protect biodiversity and repair ecosystems damaged by human activity. Different people support conservation for different reasons.
A real example: the Caledonian Forest (Scotland)
The Caledonian Forest is an ancient woodland that has existed for thousands of years and supports native species such as wildcats, red squirrels, and rare birds.
- The forest was reduced by logging, farming, urban growth, and mining
- Invasive species weakened the ecosystem
- Fragmentation reduced resilience
- Conservation and regeneration projects have helped restore parts of the forest
Damaged ecosystems can recover if human pressure is reduced and protection is long-term.
What is a perspective?
A perspective is how a person or group views a situation. Conservation choices depend on values, priorities, and worldviews.
- Different stakeholders see nature in different ways
- Perspectives influence which conservation strategies are chosen
- Conflicts can arise when priorities differ
Why protect species and habitats?
There are several reasons why people argue for protecting species and habitats.
- Aesthetic: nature is beautiful and worth preserving
- Ecological: species provide essential ecosystem services
- Economic: ecosystems supply resources and support income (e.g. tourism)
- Ethical: humans have a responsibility to protect life
- Sociocultural: biodiversity supports health, culture, and recreation
Some arguments focus on human benefits, others on nature’s own value.
Instrumental vs intrinsic value
- Instrumental value: nature is useful to humans (food, jobs, medicine)
- Intrinsic value: nature has value simply because it exists
- Economic and sociocultural arguments often overlap
In exams, clearly link each argument to either instrumental or intrinsic value.
Who is involved in conservation?
Conservation works best when many groups work together at different levels.
- Individuals: reduce ecological footprint and support conservation
- Local communities: manage land and restore ecosystems
- Businesses: adopt sustainable practices and fund projects
- NGOs: research, monitoring, advocacy, and education
- National governments: laws, protected areas, enforcement
- International cooperation: shared goals and agreements
Global cooperation for biodiversity
International agreements help countries work together to protect biodiversity.
- Global treaties guide conservation efforts
- Genetic resources should be shared fairly
- Countries aim to protect large areas of land and oceans
Biodiversity loss is a global problem that needs international solutions.
Big exam takeaways
- Conservation aims to protect and restore ecosystems
- Different perspectives lead to different strategies
- Arguments can be aesthetic, ecological, economic, ethical, or sociocultural
- Many stakeholders are involved at different scales
- Global cooperation is essential for long-term success

Choosing how to protect nature
Big idea: The way societies protect nature depends on their perspectives and values. Different views lead to different conservation strategies.
Why conservation strategies differ
Conservation does not have one single solution. Successful strategies usually combine funding, education, laws, scientific research, and community support.
- Different societies value nature in different ways
- Some focus on protecting nature for its own sake
- Others focus on how nature benefits people
Two main perspectives on conservation
Environmental perspectives shape how conservation decisions are made.
- Ecocentric perspective: nature has value on its own and should be protected
- Anthropocentric / technocentric perspective: nature is valuable because it supports human needs
Ecocentric = protect nature for nature. Anthropocentric = protect nature for people.
Ecocentric approach (low intervention)
The ecocentric view focuses on protecting ecosystems and species in their natural environments with minimal human interference.
- Protect species in their natural habitats (in situ)
- Limit human activity
- Allow natural processes like succession and evolution to occur
Large natural areas may be left mostly untouched so ecosystems can recover naturally over time.
Anthropocentric and technocentric approaches
These perspectives see biodiversity as important because it provides resources, income, and opportunities for humans.
- Use scientific management and technology
- Support conservation through tourism and economic benefits
- Protect species that are useful or important to people
Zoos, seed banks, and wildlife research centres protect species while also supporting education and income.
Fair conservation and environmental justice
Conservation works best when it is fair and inclusive. Strategies should not place unfair burdens on local or marginalised communities.
- Share both benefits and costs of conservation
- Include local communities in decision-making
- Build long-term support for biodiversity protection
Protecting species and habitats
Conservation can focus on individual species, habitats, or a combination of both.
- Species-based conservation: protect individual endangered species
- Habitat-based conservation: protect entire ecosystems
- Mixed approaches: protect key species and their habitats together
Protecting habitats often protects many species at the same time.
Designing protected areas
The success of protected areas depends on how they are designed and managed.
- Large protected areas usually support more species
- Wildlife corridors allow animals to move safely between areas
- Zonation reduces human impact by separating core and buffer areas
Core zones limit human access, buffer zones allow some activity, and transition zones support tourism and education.
Mixed conservation strategies
Many modern conservation projects combine species protection with habitat conservation.
- Focus on keystone species that support entire ecosystems
- Use flagship species to raise public awareness
- Combine habitat protection with research and breeding programmes
Protecting a well-known species can also protect the ecosystem it depends on.
Big exam takeaways
- Conservation strategies depend on environmental perspectives
- Ecocentric strategies focus on nature’s intrinsic value
- Anthropocentric strategies focus on human benefits
- Protected areas must be carefully designed
- Mixed approaches are often the most effective
Protected areas vs wildlife corridors
Big idea: In fragmented landscapes, conservation must protect core habitats and also maintain connections between them.
Protected areas
Protected areas (e.g. national parks, nature reserves) are areas of land or sea where human activities are limited to protect ecosystems and species.
- Protect large areas of core habitat
- Support stable populations and breeding
- Reduce habitat loss and direct human disturbance
- More effective when large and well-managed
- Can become isolated islands in fragmented landscapes
- Small reserves may suffer from inbreeding and edge effects
- Species may be unable to migrate or disperse
Wildlife corridors
Wildlife corridors are strips of natural habitat that link separate protected areas, allowing organisms to move between them.
- Allow gene flow between populations
- Reduce isolation caused by habitat fragmentation
- Support migration, dispersal, and recolonisation
- Make separate reserves function as a network
- Often narrow and vulnerable to edge effects
- Can expose species to predators or human disturbance
- Effectiveness depends on design and surrounding land use
Comparing the two strategies
- Protected areas conserve biodiversity by protecting habitats, whereas corridors conserve biodiversity by maintaining connectivity
- Protected areas support population survival, while corridors support population movement and gene flow
- Corridors are most effective when used alongside protected areas, not alone
Exam tip: For Compare [4], make at least one direct comparison using words like whereas, however, or in contrast.
The most effective conservation strategies usually combine large protected areas with well-designed wildlife corridors.
