What Is Wildlife Worth?

How economists put values on wild animals and nature, from tourism and ecosystem services to the value people place on simply knowing species exist.

A tiger, a coral reef or a flock of migrating birds has no price tag. Yet decisions about land, roads and dams affect wildlife every day. Economists try to estimate the value of nature so it isn’t treated as worthless.

Use values

Direct use: tourism, fishing, timber, medicinal plants.
Indirect use: services such as pollination, pest control, water purification and flood protection.

Non-use values

Existence value: people value knowing that tigers or whales exist, even if they never see them.
Bequest value: wanting future generations to enjoy nature.
Option value: keeping options open for future uses, such as undiscovered medicines.

How values are measured

Market prices: tourism revenue, fish catches.
Travel cost method: how much people spend to visit a park.
Stated preference surveys: asking people how much they would pay to protect a species.
Avoided costs: the cost of replacing a natural service, such as building a water treatment plant instead of protecting a watershed.

Why valuation matters

It shows nature’s contribution to economies, which is often invisible in GDP.
It helps compare the benefits of conservation with the benefits of development.
It can justify payments to communities who protect nature.

Limits

Some values are hard to measure reliably.
Many people argue nature has intrinsic value beyond economics, and that putting a price on species can be misleading or ethically troubling.
Values depend on who is asked: local communities and distant tourists may value wildlife very differently.

A tool, not the whole answer

Economic valuation can inform decisions, but ethical, cultural and ecological considerations also matter.

The valley decision

A government considers a dam that would flood a forest valley. The dam's electricity is easy to value. Economists also estimate the forest's value for water, tourism and wildlife, including existence value. The comparison shows that losing the forest has large costs that were previously ignored.

Thinking nature has no economic value unless it is sold

Nature provides services and values that don't pass through markets but still matter greatly to people and economies.

Key takeaways

Wildlife has direct use, indirect use and non-use values.
Existence value reflects people valuing species they may never see.
Methods include market prices, travel costs, surveys and avoided costs.
Valuation informs decisions but has ethical and practical limits.
