The White Pine Hollow State Forest is a special forest area in Dubuque County, Iowa. It covers about 944-acre (382 ha) of land. A large part of this forest, about 712-acre (288 ha), is extra special. It's known as a National Natural Landmark and an Iowa State Preserve. This means it's protected because of its unique natural features.
The forest gets its name from the tall, old white pine trees that grow there. These trees are part of an old-growth forest. This means the trees have been growing for a very long time without being cut down. It's believed to be the only group of old white pine trees still growing naturally in Iowa. The closest town to the forest is Luxemburg. This area was once called "Pine Creek Hollow" or "Pine Hollow."

What Makes White Pine Hollow Special?
Unique Environment for Plants and Animals
It's quite unusual to find white pine trees growing so far south in Iowa. White Pine Hollow is part of a special region called the Driftless Area. This area was missed by glaciers long ago, so it has unique hills and valleys.
The forest has many north-facing slopes. These slopes are called algific talus slopes. They are cool and moist, even in summer. This is because cold air escapes from cracks in the rocks. The ground here is also a type of karstland. This means it has sinkholes, caves, and big changes in how high the land is. These cool, rocky spots help the white pines and other plants survive. Scientists think these trees might be a relict from a time when Iowa's climate was much colder.
Amazing Plant Life
White Pine Hollow is home to over 625 different kinds of plants! It's like a giant natural garden.
One very rare plant found here is the northern wild monkshood. This plant is considered a threatened species. This means it's at risk of disappearing if we don't protect it.
Rare Animals Living Here
The forest also protects some very rare animals. Two types of animals that are in danger of disappearing have been seen here. These are the Indiana bat and the Iowa Pleistocene snail.
The Indiana bat is a small bat that needs specific places to live and raise its young. The Iowa Pleistocene snail is a tiny snail that lives in the cool, damp areas of the algific talus slopes. Protecting White Pine Hollow helps these special creatures survive.
How White Pine Hollow is Protected
White Pine Hollow has been recognized as an important natural area for many years. It was first named a state forest in 1934. Later, in 1967, it became a National Natural Landmark. This means it's a nationally important natural site. In 1968, it was also listed as an Iowa State Preserve, giving it even more protection under state law. These protections help make sure this unique forest stays safe for future generations.
