This article looks at how long-term weather patterns affect freshwater wetlands. Specifically, scientists looked at freshwater wetlands called Carolina bays - shallow depressions in forests that fill with rainfall during rainy seasons and that dry up during droughts. Scientists asked: Over a long period of time following periods of drought, do Carolina bays become more forested or do they always return to their aquatic ecosystem?

Thinking About Science

When scientists want to solve a problem, they collect information to understand the problem. To understand the information, scientists sometimes use a technique called classification. Classification helps scientists group and categorize many things into simpler groups. This technique can create groups that can be compared to each other. For example, if someone gave you a bag of coins, would it be easier to count the coins one by one? Or would it be easier to put the pennies with each other, the quarters with each other, and so on? It is much easier to count the money by classifying it rather than counting the coins one by one.

In this study, scientists classified vegetation in and around wetlands. The scientists classified the plants into three groups: aquatic plants, marsh plants, and woody plants. Aquatic plants include plants like water lilies that are found growing in water. Marsh plants, like grasses, can grow in shallow areas between deeper water and dry areas. Woody plants, like trees and shrubs, are plants that live in dry areas outside wetlands. This type of classification helps scientists to simplify and compare the data they collected in the study area.


Thinking About the Environment

Why should we care about freshwater wetlands? Freshwater wetlands play an important role in an ecosystem by providing ecosystem services throughout the world (figure 1).

Figure 1. Wetlands of the United States of America. Image created by Robert H. Yuhas of the United States Geological Survey.

Freshwater wetlands help clean the water by removing pollution. They act like a storage unit when floods occur. Water is held in the wetland rather than flooding people’s homes and cities. These wetlands are also homes and breeding areas for many different types of wildlife – For example, ducks, frogs, salamanders, beavers, fish, alligators, and many more. Freshwater wetlands depend on rainfall to stay wet. When a drought occurs, the water levels drop. Sometimes the wetland dries up all the way. If there is not enough water in the wetland, then this can change how the wetland does its job in the ecosystem. The scientists in this study were interested in how different amounts of rainfall affect wetlands.


Introduction

Shallow land depressions can be found within some forests of the United States. These depressions are filled by rainfall, particularly in the spring when the rains are most frequent. In certain areas of the Southeastern United States, these wet depressions are called Carolina bays (figure 2).

Figure 2. A Carolina bay.

Throughout the summer months, Carolina bays dry up as rain becomes less frequent and the temperature increases. The period from when the Carolina bays are filled by rain to the time they dry up is called a hydroperiod (hi dro per e ud). When these bays have water, aquatic plants grow in the water, and marsh plants or woody plants grow along the wet edge of the wetlands (figure 3). A Carolina bay is a freshwater wetland.

A body of water with aquatic plants
Figure 3. A Carolina bay filled with water and aquatic plants.

What does hydro mean? “Hydro” can be a part of many different words, but it always relates to water (figure 4). Knowing what hydro means can help you understand what the whole word means. For example, hydrology means the study of water. Dehydrate means loss of water for normal body function. What do you think hydropower means?

 

A hydropower dam
Figure 4. The energy created by damming waterways is called hydropower.

You may recall that freshwater wetlands provide a lot of benefits. (See “Thinking About the Environment.”) The scientists in this study were interested in whether prolonged periods of drought may enable trees and other woody plants to grow into the wetlands during the long dry periods. If that happened, the wetlands could change into a forested wetland (swamp.) This is called the directional model. It is called directional because the bays would change in only one direction. Think about how people develop and change. Think about how people change from being a baby to child to teenager to adult. People do not go from baby to teenager to baby to teenager to adult. Human development represents a directional model.

Other scientists proposed that Carolina bays could survive long periods of drought. This is called the cyclical model, because in this model the bays always return to their aquatic ecosystem.

Those scientists, however, had only studied Carolina bays for short periods of time. The scientists in this study wanted to study Carolina bays over a longer period of time. The question they wanted to answer in this study was: Over a long period of time following periods of drought, do Carolina bays become more forested or do they always return to their aquatic ecosystem?

Method

The research was conducted in an area in the Savannah River Site in South Carolina along its border with Georgia in the Southeastern United States (figure 5). The scientists identified seven Carolina bays in this area. In the spring, each of these bays was filled with water. The smallest bay was 4.5 hectares and the largest was 12 hectares.

To answer their question, the scientists decided to use the type of vegetation and the depth of the water as indicators. To measure water depth, the scientists used a water gauge (figure 6). The water gauge also helped the scientists to measure hydroperiod.

Figure 6. Water gauge in a forested swamp.

The bays were too large to identify all of the plants growing in them. To decide where in each bay the scientists would identify plants, they developed a special system to sample the vegetation. The scientists placed a post in the middle of each Carolina bay. They connected eight cables to the center post. Each cable was pulled out to the edge of the bay and connected to a post at the water’s edge. The cables were evenly spaced. Each cable was marked every 10 meters (figure 7).

Scientists recorded the types of plants growing under the eight cables in the places that had been marked. They then classified the vegetation into three types, depending on how much water the plant needed to survive. The types were aquatic plants, marsh plants, and woody plants (figure 8).

The scientists also collected information about annual rainfall (figure 9). This way, they could identify times of drought. The scientists collected information about water depth and vegetation in the summers from 1983 to 2003. They also recorded the hydroperiod of each bay for every year.

The scientists then compared the amount of rainfall, water depth, and hydroperiod with the type of vegetation growing in each Carolina bay. They did this over a 15-year period, paying close attention to what happened to the vegetation after a period of drought.

Findings

The scientists found that over a long period of time, the bays’ vegetation patterns show a cyclical model rather than a directional model. The scientists also found that vegetation patterns were influenced by current-year rainfall and last year’s rainfall. It can take up to a year for the water in a bay to recover from a drought period (figure 10)!

A line graph shows the average maximum water depth at the water gauge of seven Carolina bays from 1989 to 2003.
Figure 10. The graph shows the average maximum water depth at the water gauge of seven Carolina bays from 1989 to 2003. Compare this graph with figure 9.

The scientists discovered that when the bays were the driest, the fewest amounts of aquatic plants were found because of the low water levels in each bay. Instead, woody and marsh plants could grow and expand into the wetland. When the rains returned, the vegetation started to change again. During this recovery period, the deeper water caused woody and marsh plants to decrease. Once the bays contained a lot of water, the aquatic plants appeared again (figure 11).

Discussion

The scientists gained a better understanding of Carolina bays’ vegetation patterns. Carolina bays’ vegetation patterns show a cyclical model over a long period of time, depending on the amount of rain. These findings will help predict how other freshwater wetlands around the world might change over long periods of time.

 

Over the next 30 to 60 years, it is predicted that the world will experience climate change, likely changing annual rainfall. Climate change may decrease or increase rainfall. Although scientists do not know what will happen in the future, climate change could affect wetlands around the world. This study helps scientists understand what might
happen to Carolina bays and wetlands like them as climate change occurs.

Standards addressed in this Article:

The Next Generation Science Standards (NGSS) are a set of K-12 science education standards emphasizing inquiry-based learning, real-world applications, and integrating engineering practices, aiming to deepen understanding of science while promoting critical thinking and problem-solving skills.
  • ESS2.C-M1
    Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
  • ESS2.C-M3
    Global movements of water and its changes in form are propelled by sunlight and gravity.
  • ESS3.C-M1
    Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things.
  • ESS3.D-M1
    Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior, and on applying that knowledge wisely in decisions and activities.
  • LS1.B-M4
    Genetic factors as well as local conditions affect the growth of the adult plant.
  • LS2.A-M1
    Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.
  • LS2.C-M1
    Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
  • LS4.D-M1
    Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.

What Is a Natural Inquirer Journal?

Three Natural Inquirer journal covers with NI bee

 

A Natural Inquirer journal is a collection of 4-8 articles on a related science topic. Journals are written for a middle school audience, but they can also be adapted for both high school students and advanced upper elementary students. Some journals are particularly suited to high school students; you can find our grade level recommendations in the tags on the product page or by filtering journals by grade level.

Journals include:

  • Four to eight articles based on published, peer-reviewed research papers; the articles keep the research paper format (see more below) but are written in language students can understand.
  • A FACTivity for each article, which is an activity to complete after reading the article. The FACTivity helps reinforce major science concepts from the article. These activities are designed to be easy to implement, with few material requirements and options for adapting them for your audience or available resources. Some articles in a journal may have two FACTivities.
  • A short “Welcome to the journal” article about key background information and science concepts that unify the articles included in the journal
  • A glossary of new terms for each article and the introductory materials.
  • A list of related Natural Inquirer publications for each article as well as outside references.
  • Standards correlations, including Next Generation Science Standards, addressed in the articles and the FACTivities.

Journals may also include additional essays (called spotlights), other activities (like crossword puzzles or vocabulary challenges), and more.

Reading Modes

Journals are available in three different formats:

  • Hard copies can be ordered from the website and shipped, all free of charge.
  • PDF versions of the printed journal can be downloaded free on the website. The PDF version directly replicates the content and layout of the printed version. You can also download individual articles as pdfs.
  • The “Read Distraction Free” option allows the individual articles to open in their own window, without the rest of the website being visible. These articles can be found under the “Articles” tab. This version allows readers to scroll to particular sections of the article using the sidebar menu on the left side of the screen. This version also has interactive Reflection Sections and Number Crunches. Students can enter their answers, submit them, and then receive the correct answers to double-check their work. Submitted answers are not saved on the website and will disappear once the window is closed.

What's in a Natural Inquirer Article?

Here, we'll go into more detail about the parts of a Natural Inquirer article and give you some ideas about how they can be used.

  4. Introduction

    This section begins the scientific article format. Much like the published, peer-reviewed study this article is based on, the introduction provides background information for the study – what is currently known and what remains unknown. The introduction culminates in the question(s) the study hopes to answer.

    The introduction is also the first section with a Reflection Section. This section includes two or three questions to help kids reflect on what they’ve just learned in the Introduction. If they are using the online distraction-free reading mode, they can answer these questions directly on the website.

    Use this section to:

    • Review important background information that kids need to understand the study
    • Connect the study to the concepts addressed in the Thinking About Science and Thinking About the Environment sections
    • Understand research questions and hypotheses, including generating their own hypotheses given what they already know

    Next Generation Science Standards applications:

    • Life Science and some Earth Science Disciplinary Core Ideas (depending on topic)

  5. Methods

    This section is the nuts and bolts of the study design – the who, what, when, where, why, and how of the research. Contained within the Methods section are usually maps of the study location or the set-up of study plots, as well as details about what data was collected and how.

    The Methods section also ends with a Reflection Section – two or three questions to help students think through what they just read. These questions are interactive on the distraction-free reading mode.

    Use this section to:

    • Show students how experiments and studies are designed and carried out
    • Explore sampling methods and randomization
    • Introduce various data collection tools (e.g. camera traps, surveys, insect collection tools, weather stations, etc.)
    • Explain bias and how studies are designed to remove bias
    • Help students gain experience with map reading

    Next Generation Science Standards applications:

    • Life Science and some Earth Science Disciplinary Core Ideas (depending on topic)
    • Most Crosscutting Concepts (depending on topic)

    Note that specific standards for this particular monograph are linked on this educator guide tab.

  6. Findings

    This section summarizes the data collected during the study. The Findings section usually includes data tables or graphs and highlights the significant data points from the study. This section often mentions statistical analysis or the use of computer programs to model or analyze the data, though these methods are only discussed generally.

    The Findings section also ends with a Reflection Section – two or three questions to help students think through what they just read. These questions are interactive on the distraction-free reading mode.

    Use this section to:

    • Have students practice reading and interpreting graphs and tables
    • Compare results between variables and controls
    • Explain the concept of statistical significance
    • Discuss how no data or negative results still provide valuable information

    Next Generation Science Standards applications:

    • Life Science and some Earth Science Disciplinary Core Ideas (depending on topic)

  7. Discussion

    This section concludes each article. In it, we summarize the main findings of the scientists’ study. Additionally, we present the scientists’ ideas about the limitations of their study, the big-picture impacts of their research, and the scientists’ plans for future study or action.

    The Discussion section ends with a Reflection Section – two or three questions to help students think through what they just read, especially general take-aways from the study. These questions are interactive on the distraction-free reading mode.

    Use this section to:

    • Discuss what conclusions can and cannot be drawn from the available data
    • Explain the difference between correlation and causation
    • Explore study limitations and opportunities for further study
    • Brainstorm ways the study findings could be applied to real-world situations

    Next Generation Science Standards applications:

    • Life Science and some Earth Science Disciplinary Core Ideas (depending on topic)

Additional Resources on the Website

A screenshot of the product tabs for an NI monographOn the website, we pair each journal with a variety of other resources, as well. Use the tabs on the product page to browse through the following:

  • Related activities, including the FACTivity for each article
  • An “About” essay that gives some larger context for the research the scientists conducted or more information about the science topic from the journal
  • A glossary of all boldfaced terms from the journal
  • A “Scientists and Collaborators” page that lists the people involved in the studies in the journal; click on a researcher to reach their bio page and see what other articles they might be featured in
  • A “Related Content” page that lists both Natural Inquirer resources about similar topics and also outside reference materials

Article Selection and Review

Natural Inquirer partners with the USDA Forest Service, so we source research studies by Forest Service scientists that have been peer-reviewed and published in reputable journals. Some of our articles have also been created in collaboration with scientists from other Federal agencies, such as U.S. Geological Survey and the United Nations Food and Agriculture Organization, universities, and other non-profits.

All journal articles are reviewed by scientists who conducted the original research study to verify scientific accuracy. Journals are also reviewed by student editorial review boards of middle or high school students before publication. Additionally, all journals are reviewed by the Forest Service and the U.S. Department of Agriculture before publication.

A screenshot of the citation for "Lights, Camera, Tracks"Every journal article includes a citation of its source study. Many educators pair the original research paper with our article to help more advanced students learn how to read formal research papers. The journal article then serves as adapted primary literature, bridging the two articles.
