Overview

Students investigate plant and animal life in and around a creek. Students work in groups, with each group member performing a different task: observing, recording, mapping, classifying.  Finally, the team puts the information together to make conclusions about the ecological connections that exist within the area surveyed.

Objective(s)

  • Describe habitat characteristics of riparian areas in Yellowstone.
  • Give examples of clues in the environment that tell us what animals might be living there.
  • Identify several types of aquatic or riparian organisms.
  • Give examples of and explain the difference between biotic (living or dead) and abiotic (nonliving) components of a riparian community.
  • Explain the connections between the plant and animal communities in the stream and those near the stream.
Students may also learn the skills of measuring the temperature and pH of the water in the stream if the proper tools are available.

Background

Within Yellowstone National Park, there are more than 200 lakes, with a total of 107,000 surface acres of water, and 1,000 streams, for a total of 2,650 miles of running water. Yellowstone’s riparian (land near water) and aquatic (in the water) environments are key elements to the foundation for its healthy ecosystem. Yellowstone’s water systems provide quality habitat for native and nonnative fish, which in turn are an important food source for many of its animals, including bears, eagles, otters, mink, ospreys, pelicans, loons, grebes, mergansers, diving ducks, terns, gulls, kingfishers, and herons. Numerous insects and other invertebrates are also important life forms in streamside environments.

In a natural habitat, nonliving factors such as sunlight, air, water, soil, and rocks are just as important as the living things, because life could not exist without the proper environmental conditions. Ecologists classify living things (plants, animals, fungi, and microbes) as biotic while nonliving factors are classified as abiotic. It’s important to note the difference between dead and nonliving parts of the environment. If something is dead, it had to have once been alive, and is thus classified as biotic. Nonliving factors were never alive. Even after death, plants and animals can be homes, food sources, or provide other benefits to the living things in their habitat. All of the biotic and abiotic factors within a wild habitat like Yellowstone affect each other in many different ways, creating a complex interconnected ecosystem. There is so much life in a place like Yellowstone National Park because all of its living and nonliving parts are protected. Water and wildlife are closely linked, and so are the humans that share the environment with them.

Materials

  • Student Handout
  • Additional Materials to be included if available and appropriate for the students: field guides, pH testing equipment, thermometers 

Procedure

Park Connections

Riparian areas provide vital habitat throughout Yellowstone National Park.

Extensions

This activity may be suitable for all ages depending on how much detail is required by the educator. While younger students may be asked simply to count each thing observed. Older students may be asked for a more detailed survey utilizing field guides, measuring tapes, water quality monitoring equipment etc.

Vocabulary

riparian, biotic, abiotic, aquatic, scat
