Why is Yellowstone a biosphere reserve?
Yellowstone is designated as a biosphere reserve. Biosphere reserves are internationally recognized areas where management seeks to achieve sustainable use of natural resources while ensuring conservation of the biological diversity of the areas. The first biosphere reserves were designated in 1976.
What is Yellowstone National Park known for?
Yellowstone National Park preserves more than 10,000 hydrothermal features — an extraordinary collection of hot springs, mudpots, fumaroles, travertine terraces and—of course —geysers. Microorganisms called thermophiles — meaning “heat loving” —live in these features and give the park its brilliant colors.

There are several fundamental factors that limit ecosystem growth, including temperature, precipitation, sunlight, soil configuration, and soil nutrients. Two readily observed limiting factors are temperature and precipitation.
What are the major environmental threats to national parks?
- Invasive Species. When invasive species arrive in their new environments, they harm natural and cultural resources in our parks.
- Our Changing Climate. The global climate is changing, and so is the ocean.
- Ocean Plastics.
- Overfishing.
- Water Quality.
- Changing Habitats.
How does Yellowstone protect biodiversity?

What are the three abiotic systems?
Abiotic factors fall into three basic categories: climatic, edaphic and social. Climatic factors include humidity, sunlight and factors involving the climate. Edaphic refers to soil conditions, so edaphic abiotic factors include soil and geography of the land.
