|Pedagogical Use Description||This activity is designed for use near the beginning of a general ecology course, in an introductory course covering ecology, or in a field ecology or natural history course that may be open to nonmajors. It is intended for students with little to no background in ecology, statistics or scientific writing. Class size should be conducive to field work (10–25). Requires two 3-4 hour lab periods.
In the first lab period, students collect data in the field at a forested site where a focal species (e.g. pawpaw) has the potential to affect tree regeneration. This works best during the growing season. In the second lab period, in a classroom where students can bring or use computers, they analyze data and prepare to write a lab report.
This activity could be used at any institution with lab sections small enough for field work (10–25). It is suitable for biology majors in early stages of their college careers, nonmajors, and high school students. For more advanced courses, complexity could be increased. This lab could easily be adapted to any landscape with forests where an understory species— any native or invasive tree, shrub or herb—has the potential to affect tree regeneration. The native understory shrub pawpaw is common in moist forests across much of central eastern North America (range map: Flora of North America 2014).
