Why we protect

Pelican Island in the Indian River Lagoon (pictured) became the first national wildlife refuge in 1903, when plume hunters were shooting Florida's wading birds for hat feathers. Why do people set animals and land aside, and who decides?

From trophies to insurance

A short history

  • Ancient timesRulers in Egypt, China and Mesoamerica kept collections of wild animals as signs of power: menageries, not conservation.
  • 1752The menagerie at Schönbrunn Palace in Vienna opens; it is the oldest zoo still running.
  • 1759Kew Gardens begins in London; botanical gardens collect, name and grow plants from around the world, and today hold seed banks for wild plants.
  • 1828The Zoological Society of London opens its gardens in Regent's Park for science; the public is admitted from 1847. "Zoo" comes from "zoological garden".
  • 1872Yellowstone becomes the first national park, "for the benefit and enjoyment of the people".
  • 1889The Smithsonian's National Zoo is founded in Washington, partly to save the vanishing American bison.
  • 1903Theodore Roosevelt protects Pelican Island, Florida: the first unit of what is now the National Wildlife Refuge System, today more than 570 refuges (est.).
  • 1918The Migratory Bird Treaty Act protects birds that cross borders.
  • 1947Everglades National Park opens, the first national park set aside for its living things rather than its scenery.
  • 1971The Ramsar Convention protects wetlands of international importance.
  • 1973The Endangered Species Act (U.S.) and CITES, the treaty on trade in endangered species, are signed.
  • 1981North American zoos start Species Survival Plans: shared studbooks so zoo animals stay genetically healthy.
  • 2008The Svalbard Global Seed Vault opens in Arctic Norway as a backup for the world's crop seeds.
  • 2022The Kunming-Montreal Global Biodiversity Framework sets Target 3: conserve at least 30 percent of land and sea by 2030 ("30x30").
What protection is for

Five goals

Insurance populations

A managed group in zoos or seed banks that can restock the wild if it crashes. The California condor (22 birds in 1982, 607 at the end of 2025) and the Arabian oryx came back this way.

Reintroduction

Returning animals to places they vanished from: red wolves in North Carolina, Florida grasshopper sparrows bred at White Oak and released on the prairie.

Research

Vets, geneticists and ecologists learn how animals breed, sicken and recover; zoos pay for field work far from their gates.

Education

Most people will never see a wild elephant or condor. Zoos, aquariums and gardens are where many children first care about one.

Recreation and health

Parks and preserves give people open space, clean water and cooler air; protected wetlands also shield towns from floods.

How protected is protected?

The IUCN categories

The International Union for Conservation of Nature sorts protected areas by how strictly they are managed.

CategoryNameWhat it meansExample
IaStrict nature reserveScience only; almost no visitorsSome island bird reserves
IbWilderness areaLarge, wild, no roadsMany U.S. wilderness areas
IINational parkWhole ecosystems, with visitorsEverglades, Yellowstone
IIINatural monumentOne special featureA cave, a spring, a canyon
IVHabitat or species management areaManaged for certain speciesMany national wildlife refuges
VProtected landscape or seascapePeople and nature living together over timeFarmed national parks in Europe
VISustainable use areaNatural resources used with careCommunity forests and fisheries

Example placements are typical; the official category of each site is listed in the World Database on Protected Areas.

Protected places near us

Myakka River State Park

One of Florida's oldest and largest state parks (about 37,000 acres, est.): river, marsh, prairie and a canopy walkway; alligators, sandhill cranes and wood storks.

Robinson Preserve

A Manatee County preserve on former farmland and mangrove shore, restored with tidal channels and marsh (about 680 acres after expansion, est.).

Terra Ceia Preserve State Park

Mangrove, salt marsh and pine flatwoods on Tampa Bay, protected as part of a state buffer preserve.

Egmont Key

An island at the mouth of Tampa Bay: a state park and a National Wildlife Refuge (1974), with nesting shorebirds, gopher tortoises and sea turtles.

Tampa Bay Estuary Program

Since 1991, cities, counties and agencies have cut nitrogen pollution so seagrass could return; seagrass grew back for decades, then declined again after 2016 (TBEP monitoring).

Grades 6–12 · a debate

Who decides what is protected, and how?

Fortress conservation or community conservation?

One side

Fences and rangers keep poachers, cattle and roads out. Strict reserves have protected tigers, rhinos and old-growth forest that would otherwise be gone, and some species can only survive where people are kept away.

The other side

Many parks were made by removing the people who lived there: Shoshone, Bannock and other nations were pushed out of Yellowstone, and the same happened in Africa and Asia. Studies find that land managed by Indigenous peoples and local communities often keeps forests as well as or better than strict parks, at less human cost.

Are zoos part of the answer?

One side

Accredited zoos breed endangered species, fund field work and reach millions of visitors each year. Some species exist today only because of zoo programs.

The other side

Most zoo animals belong to species that are not threatened, and money spent on captive animals might do more protecting habitat. Some animals, such as elephants and orcas, may never thrive in captivity.

Shifting baselines

One side

Every generation sees a world with fewer animals than its grandparents knew. Remembering what was lost (oral history, old photos, museum records) sets better goals for restoration.

The other side

Nature has always changed, and some argue that aiming for a lost past is impossible; better to aim for healthy, working ecosystems in today's climate, even if they look different.

Grades K–5

Why do people make zoos and parks?

Some animals are in trouble. Parks keep their homes safe. Zoos keep a few animals safe and help us learn about them, so we can help the wild ones too. What wild place near your home would you protect?
