Black cohosh is a forest plant that is harvested for its medicinal use. Black cohosh is native to eastern deciduous forests and can be found as far south as Georgia, north to southern Ontario, and west to Missouri. Not much is known about how harvesting affects black cohosh populations. Some scientists, however, have observed a decline in black cohosh populations that may be a result of harvesting these plants. The scientists in the study wanted to examine the impacts of harvesting on black cohosh. In particular, the scientists wanted to determine what amount of harvesting would be sustainable.

What Kinds of Scientists Did This Research?

Forest Ecologist: This scientist studies the diversity of forest plants and their relationship with the surrounding environment including sunlight, moisture, soil nutrients, and effects of disturbances like invasive plants and insect pests.

Forest Products Technologist: This person studies forest management and the effects of management on products we use every day, like furniture, paper, building supplies, or medicinal ingredients.

Thinking About Science

Sometimes scientists study something that has already been studied. When scientists do this, they gather, read, and summarize all the research that has been completed. This process is often called a literature review. Scientists look at how other scientists researched the problem and then come up with their own research question and design an experiment to help answer their question.

 

However, there are times when scientists do not have access to much previous research. When that happens, scientists first look at what general information is known as well as the research that has been conducted on similar topics. Using that information, the scientists come up with their own research question and design an experiment to help answer it.

 

You will learn that the scientists in this research did not have much previous research to examine prior to beginning their research. Therefore, they created new questions similar to research conducted by other scientists.


Thinking About the Environment

Forests are filled with a variety of natural resources. Natural resources are parts of the natural environment that meet human needs such as wood for housing, plants for food and medicine, and water for drinking. Native and naturalized plants and fungi are collected from forests for medicinal, edible, decorative, or other reasons.

 

Scientists estimate that 4,000–6,000 plant species worldwide are collected from forests for these purposes. Nearly 200 species are harvested from North American forests. Half of those species are in the forests of the southern Appalachian Mountains (figure 1).

 

Heavily forested mountains

Some examples of medicinal plants are American ginseng (figure 2), goldenseal, slippery elm, and black cohosh. These are slow-growing, perennial forest herbs. The belowground material of these plants is the part mostly used for medicinal purposes.

Did You Know?

The word “cohosh” comes from an Algonquin (al gän kwē ǝn) Indian word meaning rough. Rough describes the dark, hard, knotted rhizomes of the plant that contain the plant’s medicinal properties.

Figure 5. Appalachian cove forests have the right conditions for black cohosh to thrive. FIND Outdoors photo by Jessica Nickelsen.

Black cohosh grows in a variety of conditions. Appalachian cove forests are an example of an area where black cohosh can be found. Appalachian cove forests are sheltered areas that have moist, fertile soil (figure 5).

Black cohosh is harvested, or collected, from the forest. Not much is known about how harvesting affects black cohosh populations. Some scientists, however, have observed a decline in black cohosh populations that may be a result of harvesting these plants.

Scientists determined that harvest impacts could be particularly high for black cohosh because it is collected for its roots and rhizomes (figure 6). Roots and rhizomes are a part of the belowground plant material.

Due to the increasing harvest and use of black cohosh, the scientists in the study wanted to examine the impacts of harvesting on black cohosh. In particular, the scientists wanted to determine what amount of harvesting would be sustainable.

Figure 7. The George Washington and Jefferson National Forests encompass approximately 1.8 million acres of land across three States. Which two famous people is this national forest named after? What famous title did both of those people have? FIND Outdoors map by Carey Burda and Stephanie Pfeiffer Rossow.

The research was conducted in parts of the George Washington and Jefferson National Forests (figure 7). This national forest encompasses approximately 1.8 million acres of land in Virginia, West Virginia, and Kentucky. The research site was in a Virginia portion of the national forest.

 

In June 2005, a 100-meter transect was established along the upper edge of the research site. The transect was located 3 meters from a Forest Service road (figure 8). This area was named Site 1.

Thirty-six plots were created within Site 1. The plots were divided up by different harvesting treatments. The harvesting treatments were 0 percent harvest, 33 percent harvest, or 66 percent harvest (figure 9). The 0 percent harvest was used as a control. In June 2007 and June 2009, the scientists added new transects named Site 2 and Site 3. These sites were designed in the same way as Site 1.

 

An illustration showing how different harvesting treatments were distributed in the study plot.

Figure 9. Site 1 consisted of 1 transect and 36 subplots. Each subplot was designated as either 0 percent harvest, 33 percent harvest, or 66 percent harvest.

The scientists gathered a variety of growth measurements from each subplot, such as stem density, plant height, and foliage height and canopy dimensions (figure 10).

 

The top illustration shows larger diameter trees that are spaced farther apart. The lower illustration shows smaller diameter trees that are growing more closely together.

Figure 10. These illustrations show how the density of trees can vary depending on size and location of the trees.

In subplots which included harvesting, the scientists used techniques which mimic the way black cohosh has been harvested traditionally (figure 11). All aboveground and belowground plant material were extracted as completely as possible. However, some rhizome fragments were likely left behind in the soil.

Figure 11. During each harvest, the scientists attempted to get all aboveground and belowground material from the black cohosh. It is possible that small pieces of the roots remained in the soil after the harvest.

FIND Outdoors illustration by Stephanie Pfeiffer Rossow.

The growth measurements and harvests were conducted annually in June of each year beginning with the first year each site was established. The years that each site was studied were:

• Site 1: 2005–2007
• Site 2: 2007–2009
• Site 3: 2009–2011

During analysis of the results, the scientists removed any subplots that did not contain black cohosh.

Findings

The size and density of black cohosh plants were similar across the test subplots before harvesting. After 2–3 years of harvesting, most growth measurements for the black cohosh had declined (figure 12).

After the last year of harvesting in the 66 percent harvest plots, black cohosh had 80–90 percent less foliage area and stem density. Black cohosh in the 33 percent harvest plots had 70–80 percent less foliage area and 65 percent less stem density.

 

Three graphs showing the stem density each year for the three different harvesting treatments at three different sites.

Figure 12. Examine the changes in stem density for black cohosh populations after 3 years of experimental harvest and the following regrowth. Stem density measurements were taken immediately before application of harvest treatments. H0 stands for preharvest year, H1 stands for harvest year 1, R1 stands for recovery year 1, and so forth.

FIND Outdoors illustration reproduced by Liz Sisk.

The scientists also found differences between the treatment plots and the control plots for at least 2 years after harvests ended. When looking at all measurements, 3 years after harvesting ended at Site 1, there was no noticeable difference between the treatment plots and the control plots.

Discussion

Before this research, not much was known about the effect of harvesting on black cohosh. However, some research had been completed on a few other forest herbs. Results from this black cohosh research are similar to studies of some other forest herbs. At high harvest levels, plant recovery is slow or limited, especially when the roots or other belowground parts (like rhizomes) are collected for their medicinal properties.

The scientists noted that research on nontimber forest products like black cohosh has focused mostly on the population of a species. They determined that it is important for future research to also consider the effects of harvesting on ecosystem services and community structure. Community structure is the number of species in a natural community and their populations.

Some studies have suggested that overharvesting of forest herbs like black cohosh could impact nutrient cycling, invasive species, and small mammal populations. Therefore, the scientists said that there is a need for improved understanding and management of native populations to support long-term sustainability of a population.

Did You Know?

Nontimber forest products are any products or services provided by the forest other than timber. They include things such as fruits, nuts, vegetables, fish, medicinal plants, and more.

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.
  • ESS3.A-M1
    Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. These resources are distributed unevenly around the planet as a result of past geologic processes.
  • 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.C-M2
    Typically as human populations and per capita consumption of natural resources increase, so do the negative impacts on Earth unless the activities and technologies involved are engineered otherwise.
  • ETS1.B-M2
    There are systematic processes for evaluating solutions with respect to how well they meet criteria and constraints of a problem.
  • ETS1.C-M2
    The iterative process of testing the most promising solutions and modifying what is proposed on the basis of the test results leads to greater refinement and ultimately to an optimal solution.
  • LS1.B-M3
    Plants reproduce in a variety of ways, sometimes depending on animal behavior and specialized features for reproduction.
  • LS1.B-M4
    Genetic factors as well as local conditions affect the growth of the adult plant.
  • 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.
  • LS2.C-M2
    Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health.
  • 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.
The Common Core Standards are educational benchmarks in the United States that outline clear expectations for what students should know and be able to do in English language arts and mathematics from kindergarten through 12th grade, aiming to ensure consistency and coherence in education nationwide.
  • Cite specific textual evidence to support analysis of science and technical texts.
  • By the end of grade 8, read and comprehend science/technical texts in the grades 6-8 text complexity band independently and proficiently.
  • Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.
  • Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
  • Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.
  • Analyze the structure an author uses to organize a text, including how the major sections contribute to the whole and to an understanding of the topic.
  • Analyze the author's purpose in providing an explanation, describing a procedure, or discussing an experiment in a text.
  • Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).
  • Distinguish among facts, reasoned judgment based on research findings, and speculation in a text.
  • Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.
Social Studies Standards are educational guidelines outlining the essential knowledge, skills, and concepts students should learn in subjects such as history, geography, civics, and economics, aiming to provide a comprehensive understanding of societal structures, historical events, and global perspectives.

What Is a Natural Inquirer Monograph?

3 Natural Inquirer monograph covers.

 

A Natural Inquirer monograph is a short publication that focuses on a single research study. Monographs are written for a middle school audience, but they can also be adapted for both high school students and advanced upper elementary students.

Monographs include:

  • One article based on a published, peer-reviewed research paper; the article keeps the research paper format (see more below) but is written in language students can understand.
  • A FACTivity, 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 monograph may have two FACTivities.
  • A short “Welcome to the monograph” article about key background information and science concepts.
  • A glossary of new terms from the article or the introductory materials.
  • A list of related Natural Inquirer publications as well as outside references.
  • Standards correlations, including Next Generation Science Standards, addressed in both the article and the FACTivity.

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

Reading Modes

Monographs 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 monograph can be downloaded free on the website. The PDF version directly replicates the content and layout of the printed version.
  • The “Read Distraction Free” option allows the monograph article to open in its own window, without the rest of the website being visible. “Read Distraction Free” is available on the article version of the monograph, which can be opened 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.

  2. Thinking About Science

    This section briefly describes a concept about science or scientific research. This overview can touch on topics like

    • study type (longitudinal study, quantitative vs. qualitative data),
    • behaviors of scientists (conducting literature reviews, collaborating with other specialists, replicating earlier studies),
    • the practice of science (the scientific method, engineering design, data collection, randomization, controls and variables),
    • or other aspects of science (bias, correlation vs. causation).

    Use this section to:

    • Reinforce steps in the scientific method and the process of science
    • Encourage students to think about the practice of science and what it can and cannot tell us
    • Consider the many types of scientific study and what information each type can provide

    Next Generation Science Standards applications:

  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

  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

  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

  7. Discussion

    This section concludes each monograph 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

Additional Resources on the Website

A screenshot of the product tabs for an NI monographOn the website, we pair each monograph 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 article
  • A glossary of all boldfaced terms from the article
  • A “Scientists and Collaborators” page that lists the people involved in the study; 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 monograph articles are reviewed by scientists who conducted the original research study to verify scientific accuracy. Monographs are also reviewed by student editorial review boards of middle or high school students before publication. Additionally, all monographs 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 monograph 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 monograph article then serves as adapted primary literature, bridging the two articles.
