How effective is protected areas?
Significance. Protected areas (PAs) are a key strategy for conserving nature and halting the loss of biodiversity. Our results show that while many PAs are effective, the large focus on increasing terrestrial coverage toward 17% of the earth surface has led to many PAs failing to stem human pressure.
How do protected areas affect biodiversity?
The creation of protected area networks helps to reduce biodiversity loss and provides significant contributions to global conservation efforts. However, despite the fact that the surface area of designated protected areas has steadily increased since 1970, the rate of biodiversity loss continues to increase.
What percentage of the world is protected?

What is a protected area?
Protected areas are internationally recognised as major tools in conserving species and ecosystems. Up to date information on protected areas is essential to enable a wide range of conservation and development activities.
Why protect the world’s forest?
Protecting the world’s forest lies at the heart of preserving biodiversity. The map here shows the share of forest area that is within legally established protected areas. Unfortunately, protected areas do not guarantee that forests are safe from deforestation and overexploitation.
