Abstract – The summer 2022 prairie ecology course at Iowa Lakeside Laboratory collaborated
with the state ecologist to complete a botanical survey of a grazed native prairie in northwest Iowa.
Data collection included the use of Esri Survey123 and a team-based approach to data collection.
Long-term objectives of this field course are to prepare young field scientists with authentic learning
experiences relative to existing and future careers in field science. This case includes lessons
learned and potential next steps for training a new generation of grassland ecologists.
Introduction
Field science in the 21st Century retains many fundamental elements of basic scientific
inquiry. However, the advent of digital devices and related technologies provide opportunities
for budding field scientists to experiment with new methods of gathering data.
In summer 2022, the prairie ecology course at Iowa Lakeside Laboratory partnered with
the state ecologist to conduct a botanical survey comparing grazed and ungrazed tracts
of a native prairie in northwest Iowa. Using a team-based approach and digital tools such
as Esri Survey123 and plant identification apps, students engaged in authentic fieldwork
that blended traditional methods with emerging technology. Guided by the Undergraduate
Field Experiences Research Network (UFERN) model, this project fostered teamwork
and hands-on learning while navigating challenges related to digital tools and sampling
protocols. Anecdotal observations suggest light grazing favored or disfavored select species,
though overall species richness remained similar between treatments, with quantitative
results to be presented in a subsequent publication. These findings inform adaptive
management decisions at Kirchner Prairie and position the site as a future testing ground
for integrated data collection, analysis, and student training in field ecology. While traditional
methods of field science retain core elements of basic scientific inquiry, this experiment
enabled an integration of digital technologies for enhanced data collection methods
and an innovative approach to initiate and sustain student engagement. By integrating
mobile devices and applications into a systematic vegetative survey comparing grazed
and ungrazed tracts of a native prairie, this project combined traditional techniques with
commonly used devices to create a multifaceted learning environment. Through teamwork
and reliance on familiar resources, students explored new potential dimensions of
field science while making an authentic contribution to applied ecological management.
The study addressed the following questions:
1. How effective are mobile devices as tools for systematic vegetative surveys?
2. Can integrating personal mobile devices encourage future car eers for field scientists?

Historical vs current status of systematic botanical surveying as a method of placebased
practice
For several decades, scholars have noted a shift in undergraduate education away from
natural history-based experiences toward a greater emphasis on digital and laboratorybased
sciences, thus diminishing opportunities for experiential learning in botany and
field ecology (Wilcove & Eisner, 2000; Kramer, 2015). However, field-based inquiry
remains vital, especially when addressing complex environmental issues. Place-based
education frameworks encourage multisensory engagement, mentorship, and career
development through immersive experiences (Fors et al., 2013; Sobel, 2004). At a time
when understanding ecological systems is critical in the face of climate change and Anthropogenic
impacts abound, there is an urgent need to recruit and inspire students to
pursue careers in field-based science. Traditional field science often occurs as a solitary,
analog process of data collection and interpretation. More technologically advanced sciences
for coursework, majors and career choices have eclipsed natural history, botany and
field research as career choices and majors over the past quarter century (Wilcove & Eisner,
2000; Woodland, 2007). Emphasis on STEM careers since the early 2000s coincided
with generations of both parents and children hesitant to engage in outdoor experiences,
opting instead for indoor experiences guided by devices, software and passive learning;
resulting in an “extinction of experiences” relative to nature (Beery et al., 2023; Gaston
& Soga, 2020; Louv, 2008). In recent years, “connectivity” in education has referred more
to enabling high speed internet access for education and interpreting an inundation of
digital data, rather than re-connecting humans and natural systems to address challenges
related to climate change, resource scarcity, biodiversity and habitat loss (Pietrzak, 2017).
Meanwhile, complex environmental problems persist and the need for future experts in
field sciences grows ever more imperative.
Data scientists are necessary for solving contemporary problems, and their work must
be complemented by experts who can contextualize the results of their analysis. Natural
history remains the foundation for knowledge of systems and organisms found in nature,
even as the information age expands the extent and dimensions of data available for
study (Bartholomew, 1986; Boyd, 2006). For more than a century, ecologists, botanists
and natural historians have expounded on the “endangered” condition of university programs
and course offerings, giving weigh to subjects and material more rooted in digital
platforms, device and molecular technologies, leading scholars to specialize in methodology
and often overlook the very systems in which the subjects of study exist (Grant,
2000; Jordan, 1916; Kruckeberg, 1997; Peters, 1980; Schmidly, 2005). The result is fewer
than half the federal workforce, to date, likely engaged in critical plant-based sciences
but lacking basic botany skills necessary to fully understand or implement appropriate
strategies (Kramer, 2015). Desktop data analysts can likely model biogeochemical conditions
using state-of-the art digital tools but may not necessarily understand the context
of their work in a real-world setting.
Emphasis on STEM-based skills in education often prioritize career choices and skills
development for careers lacking field-based experiences. While the sciences may have
shifted toward genetics, molecular extractions and other lab-based experiments related to
organisms found in nature, social rhetoric continues to reinforce the human connection to
place, single species and ecosystems as a means of management, protection and preservation
(Dodinet, 2016; King & Achiam, 2017). A student’s connection to place serves as a
foundation for not only basic education, but also in a manner that can foster a positive,
formative, mentor-led multisensory experience (Fors et al., 2013; Powell, 2010; Sobel,

2004; Vander Ark et al., 2020). STEM-based education has the capacity for including
field sciences in a way that also incorporates the use of modern technologies. However,
if students are reluctant to spend time outdoors, such experiences prove challenging.
While Thoreau, Muir and Leopold may have extolled the virtues of time spent in nature
as a balm for societal maladies, today’s experience may be looked upon less fondly
by a more digitally focused youth. When subjected to unfamiliar places and spaces, young
people today may not embrace the opportunity with the same zeal for nature and the outdoors
as their predecessors. Research on the societal impacts of the CoVID-19 pandemic
also suggest young people experience a heightened sense of anxiety with greater fear of
uncertainty and are inherently more risk averse (Cerbara et al., 2020; Gewalt et al., 2022;
Nadareishvili et al., 2022; Scerri et al., 2020; Xie et al., 2020). Instead of a source of
solace and relaxation, an outdoor experience for some young people can be riddled with
anxiety, fear, and concern for personal safety due to the lack of familiar and comfortable
conditions they may associate with work indoors.
A relatively low-risk opportunity to re-associate nature and field-based learning can
occur at the undergraduate level for today’s students due to the short-term nature of course
activities, as well as emphasis on methodology, skill building and appropriate techniques in
the sciences. Outcomes of undergraduate field experiences are a function of each student’s
perspective, resulting from the interface of personal identity and the structure and process
of the experience itself (Hodder, 2009; O’Connell, Hoke, Giamellaro, et al., 2021). Students
are able to gain not only a fundamental knowledge of ecological and scientific principles,
but also a broad understanding of practical application and career development through
hands-on learning. This includes opportunities not traditionally available to underserved
communities (Riggs, 2005). Biological field stations, marine laboratories, and geoscience
field camps provide myriad opportunities for student engagement, mentorship and early
career development for the undergraduate (O’Connell, Hoke, Berkowitz, et al., 2021). This
unique combination of student-focused activities provides an opportunity to overcome a
portion of anxieties and uncertainties associated with field-bas ed scientific research.
Beginning in 2020, Iowa Lakeside Laboratory engaged with the Undergraduate Field
Experiences Research Network (UFERN) through a series of workshops designed to support
collaboration among field stations, marine labs, and STEM research teams focused on
immersive outdoor learning (www.ufern.net). This partnership led to the intentional incorporation
of the UFERN model into faculty development and course design for the 2021
and 2022 IALL:3034 Prairie Ecology summer field courses at Iowa Lakeside Laboratory
Regents Resource Center, located in northwestern Iowa. The UFERN framework highlights
the interplay between student perspectives and the structure of field-based programs, emphasizing
how worldviews, a sense of scientific belonging, and student empowerment shape
learning outcomes. By grounding its pedagogy in this model, the prairie ecology course
fostered mentorship, skill-building, and project ownership through collaboration with technical
experts and use of digital tools. These experiences supported students in developing
technical confidence, a strong sense of identity as scientists, and the self-authorship necessary
for sustained engagement in field-based science careers. The UFERN model approach
extends from a structured undergraduate research experience where collaboration with technical
experts, skills development and a sense of project ownership lead not only to a sense of
technical confidence and personal identity, but also an enculturation of scientific expertise
and self-authorship as fundamental outcomes (Auchincloss et al., 2014). This framework
provides guiding principles for general field-based education at the undergraduate level and
also serve as the foundation for methods applied as part of this project.

Materials & Methods
Study Area; Kirchner Prairie
Located in rural Clay County, Iowa, Kirchner Prairie is a remnant prairie pasture
comprised of a diverse vascular plant community. A 2012 species inventory recorded 158
unique vascular plant species, followed by a biennial systematic inventory, documenting
155 unique species (Rosburg, 2013). The site is actively grazed, with physical exclosures.
The site is approximately 20 miles from Iowa Lakeside Laboratory and has been included
in field excursions for the IALL:3123/3125 Prairie Ecology field course since 2021. See
Figure 1. The field study site is located approximately 20 miles southeast of the Iowa
Lakeside Laboratory campus in rural Spencer, Iowa.
Methodology
The UFERN pedagogical model played a central role in shaping the structure, design,
and delivery modalities of the Prairie Ecology course (IALL:3034/3123), beginning in
2022.The UFERN framework emphasizes the interplay between student identity, program
structure, mentorship, and self-authorship as guiding principles for undergraduate field

experiences. Within this context, the Prairie Ecology course was designed to provide students
with authentic, hands-on opportunities to conduct fieldwork in collaboration with
practitioners and content experts, including the State Ecologist. By situating the Kirchner
Prairie survey within the UFERN framework, the course aligned skill-building and technical
training with mentorship and teamwork, thereby supporting both ecological data collection
and professional development outcomes for students. Table 1 summarizes pedagogical
dimensions and application of UFERN principles to the Prairie Ecology field experience as
a structured lens for evaluating both student learning outcomes and ecological results.
In 2022, Kirchner Prairie was included as a two-day field experience for students to
engage in a systematic plant survey of the site, led by State Ecologist, Dr. John Pearson. Students
were equipped with an Esri® ArcGIS Online Survey123™ form, accessible by their
mobile phones, to capture species names, geographic locations and qualitative assessments

of abundance within a total of 200 one-square meter plots arranged in linear transects. Half
of the transects were located within the ungrazed exclosure area and the remaining transects
were within the actively grazed portion of the site.
The Survey123 form was used by four team members to record species names and cover
levels (1: low, 2: moderate, 3: high) as indicated by Pearson. One student served as a project
scribe, documenting the species list and abundance scale for each transect in a field notebook.
While statistical analysis and additional quantitative metrics will be explored in a subsequent
paper focused specifically on comparative ecological outcomes, the present study emphasizes
the integration of digital tools with field-based learning methods.
For all, including our State Ecologist, this was a new experience and opportunity for learning.
With limited outdoor activities included in previous coursework for nearly all students
involved, and none directly pertaining to activities commonly conducted by professional field
scientists, the entire class were beginners at any form of systematic surveying. Methods in use
by the students were also a deviation from traditional methods among existing practitioners.
By collecting both analog and digital records from the 100 plots in both grazed and ungrazed
areas of the parcel, students were able to generate a redundant dataset for quality assurance
purposes, and also immediately generate a dataset for further quantitative analysis.
Students used a mobile application to collect data offline, which automatically uploaded
as soon as they returned to campus and connected to a strong Wi-Fi signal. Hard copy
records were then referenced when reviewing and editing data prior to any quantitative
analysis. Notes were recorded in both digital and analog formats to document any errors
that needed correction after data collection. The authors collaborated on final data revisions,
which took place later in the year.
Results
The first day of data collection spanned a total of more than nine hours in the field. Day one
required both general orientation to the sampling process, as well as gaining a sense of comfort
and flow with the data entry process. By establishing a routine to the process, including sequential
data entry and familiarization with the tools, the second day was a six-hour duration. Three
students participated in digital data entry on Day One, and five assisted with Day Two data entry,
also likely contributing to the reduced duration. Once the team returned to the Iowa Lakeside
Laboratory campus and regained network connectivity, all data were submitted.
The students recorded 2,162 unique records of plant species identified during the two-day
survey July 28 and 29 at the field site. Rapid data analytics generated from Survey123 identified
a total of 1,085 records of species occurrence (50.19%) in the actively grazed transect,
with 1,077 individual species occurrences in the protected exclosure (49.81%). Using the general
classification system within the Survey123 field form, species cover was predominantly
moderate for 1,068 or 49.4 percent of all plants identified. Anecdotal interpretation of the data
indicate low cover for 864 individual species occurrences, or 39.6 percent of all occurrences
identified, and 230 occurrences identified were classified as having high cover, at 10.64 percent
of all occurrences identified. Together with frequency data, these observations serve as
the foundation for further analysis and interpretation, which is planned fora subsequent paper.
Overall, a total of 106 species were recorded from the 200 quadrats spread across the
two combined tracts, with 94 species in the ungrazed exclosure and 79 species in the grazed
pasture. The species most frequently encountered were smooth brome (Bromus inermis, 68
quadrats in the grazed tract), big bluestem (Andropogon gerardii, 55 quadrats in the ungrazed
tract), and golden alexanders (Zizia aurea, 53 quadrats in both the grazed and ungrazed tracts).
Many species were recorded in only single quadrats per tract: 17 in the ungrazed tract and

15 in the grazed tract; examples are common milkweed (Asclepias syriaca), wild flax (Linum
sulcatum), and prairie turnip (Pediomelum esculentum). Species occurring in only a few
quadrats were not useful in discerning contrasts in dominant vegetation between grazed versus
ungrazed tracts, so only the most frequent 15 species in each tract (occurring in 25 or more
quadrats in at least one of the tracts) were utilized in the following analysis (see Table 2).
Preliminary inspection of results indicated that the ungrazed tract exhibited a greater frequency
of six species: big bluestem, gray-headed coneflower, yellow loosestrife, Kentucky
bluegrass, Virginia mountain mint, and smooth blue aster. The grazed tract had a greater
frequency of nine species: porcupine grass, purple meadow-rue, panic-grass, redtop, cream
indigo, smooth brome, wild rose, prairie coreopsis, and rattlesnake master. Three species –
golden alexanders, western sunflower, and Missouri goldenrod – showed little or no difference
in frequency between the grazed and ungrazed tracts. Among native species, six species
were more frequent in the ungrazed tract while seven were more frequent in the grazed tract.
Among non-native species, one – Kentucky bluegrass – was more frequent in the ungrazed
tract while two – redtop and smooth brome – were more frequent in the grazed tract. Shifts
of frequency among native species illustrate their adaptability to a range of grazed and
ungrazed conditions and are viewed by natural resource managers as a benign outcome.

However, apparent increases in the frequency of non-native species in the grazed tract is
concerning to managers wishing to utilize grazing as a management tool while maintaining
the prairie in a predominantly native condition. Additional study is underway to further
evaluate this outcome, including consideration of alternative grazing regimes that do not
facilitate increases of non-native species.
Discussion
The following details highlight key aspects of the UFERN model as it relates to the field
work and student experiences incorporated with this project. Generally speaking, students
gained an authentic, hands-on experience with a professional mentor in the field; they gained
insight to customary field science methods and procedures related to systematic sampling in
prairies; and they learned first-hand the conditions under which such work takes place, growing
credibility and understanding of the rigor associated with field science and ecology.
Mentorship benefits
During this exercise, students interacted with experts who use science to monitor
and improve management of natural resources. Quick digital summary of data shortly
after finishing a day’s field work enabled managers to share identification of positive
and negative implications of the results, in turn providing students with the gratification
that their effort truly contributed toward a meaningful follow-up.
Methodological and Technical Lessons
Upon submission of the species identified in the hundredth plot of the actively grazed
transects, data were immediately available for analysis in tabular form, saving hours of
manual data entry which would normally occur after two full days of field work. Survey123
generated initial summary statistics, categorical summaries, and eliminated a
time-consuming step of data entry typical with field survey work of this kind.
Survey123 facilitated data entry and preliminary analysis, eliminating transcription
errors and streamlining the field-to-database process. However, connectivity issues and
battery drain were limitations. Offline mode and backup power sources were necessary.
Compared to analog-only methods, Survey123 increased data collection efficiency but
required up-front training and troubleshooting. Should field assistants have adequately
charged devices and secondary power supplies, and download applications for offline
use, these challenges can likely be averted in future applications.
Student Preparedness and Resilience in the Field
As a relatively remote location in rural Iowa, data connectivity was sporadic. Students
who had not downloaded the full application for offline usage were unable to successfully
implement the tool. Furthermore, students not entirely comfortable with long hours
in the field experienced discomfort. One student experiencing distress left the field site
and returned to the vehicle for over an hour during the first morning of data collection.
Conversely, the team of data collectors expanded on the second day to include other students
from the field station who had expressed interest in learning about the process and
experiencing a systematic field survey. Team-based discussions regarding efficiencies in
data collection refining the process and enabling equal opportunities for experience were
part of the first day’s exercise. By Day Two, and with the addition of two new participants,
the process was refined and completed with added enthusiasm for the project. The

manual data scribe remained the same for both days to ensure consistency, and the rest of
the team rotated a sequence of entering single-species data into the Survey123 form. The
UFERN framework shaped course design by emphasizing team-based inquiry, mentorship,
and student agency. While formal assessment was not conducted, anecdotal observations
indicate increased confidence and curiosity. At the time of publication two students
who participated in the project have since pursued careers in field-based ecological work
and credit this experience as a formative influence. Future iterations of this project will
incorporate reflection tools to better evaluate short- and longer-term outcomes.
A new site survey was planned for 2024, once again involving student participation
and the use of the Survey123 form, allowing for direct comparison of these results
with previous assessments conducted by both Pearson and Rosburg. The form will be
revised to align more succinctly with preferred field methods identified by Pearson.
Technological requirements will ensure all students are capable of operating the tool in
a remote area with ample battery capacity.
For students considering field science careers, yet lack fundamental coursework in
natural sciences, field botany and survey methods, such an activity can provide an initial
opportunity to determine whether or not the experience is one worthy of further pursuit.
For some, the experience may be too tedious and physically strenuous, while for others it
may be an inspiration leading to a career of field-based science. In addition to immediate
gains in confidence and technical competence, several students from this and previous
years of the Prairie Ecology course have translated their field experiences into concrete
career opportunities. Alumni have gone on to serve as technicians at the Iowa DNR Prairie
Resource Center, wildlife management unit interns, seasonal field assistants with The
Nature Conservancy, and staff members for County Conservation Boards. In each case,
students reported that the course provided foundational skills in plant identification, ecological
sampling, and the integration of modern digital tools such as Survey123. These
outcomes underscore the role of the field course not only as an academic exercise but also
as a formative professional stepping stone, consistent with UFERN’s emphasis on identity
formation, agency, and career persistence in ecological sciences.
Conclusion
The basic fundamentals of inquiry, research and data collection remain constant elements
of science regardless of the tools, technology and skills applied in the field or
elsewhere. An analog approach to knowledge will always be under threat as technology
continues to evolve to solve global problems. Teachers and mentors are remiss to ignore
and or eliminate the opportunities to integrate technology with traditional methods. At a
minimum, such an approach may alleviate discomfort for students, and may possibly enable
innovation by a younger technophile that older generations may not even consider. The key
is to strike a balance between data integrity and the convenience of technological solutions.
The evident career paths of course participants into positions with state agencies, conservation
nonprofits, and local land management entities further demonstrate the value of this
approach to learning as both a pedagogical model and a professional training ground for
future prairie ecologists. Blending traditional botanical survey methods with digital tools
like Survey123 enabled undergraduate students to contribute meaningfully to ecological
research while gaining practical field experience. This hybrid approach, grounded in the

UFERN model, supported both ecological insight and pedagogical goals. These field-based
observations of species-specific grazing responses and cattle movement patterns illustrate
how student learning activities can simultaneously generate insights of practical value for
adaptive prairie management. Future work will refine the survey form, explore additional
metrics, and implement student feedback to enhance learning.
