Why are there only pine trees in Yellowstone?
The volcanic rocks beneath much of Yellowstone form nutrient-poor soils. These areas generally have extensive stands of lodgepole pine, which are drought tolerant and have shallow roots that take advantage of the nutrients in the soil. Lodgepoles are the only pine in Yellowstone whose needles grow in groups of two.
Why are the trees in Yellowstone so small?
Some volcanic soils in Yellowstone have few nutrients, and so support only a few trees. Other soils are more productive, supporting dense stands of new tree growth.
What is causing the populations in Yellowstone National Park to change?
Warmer temperatures are accelerating the melting of mountain glaciers, reducing snowpack, and changing the timing, temperature, and amount of streamflow. These changes are expected to result in the loss or relocation of native species, altered vegetation patterns, and reduced water availability in some regions.
Why is Yellowstone Lake so cold?

What is the biggest threat to national parks?
