FIELD TECHNIQUES: Estimation of Plant Populations
Issued by
University of Texas at San Antonio
The earner has attended a session in the field to estimate woody plants using the quadrat method and the estimation of herbaceous plant diversity and abundance using the Daubenmire frame method. The earner has also calculated the appropriate metrics for each method, and presented the data in a form that clearly describes the plant communities and meets professional standards. To join field workshops, contact julian.chavez@utsa.edu for more information and calendar events.

Earning Criteria
-
The Learner must be one of the following: (1) A current undergraduate student pursuing a degree in Environmental Science at UTSA with 60 hours or more, (2) A current graduate student in Environmental Science at UTSA, or (3) A previous student with an undergraduate or graduate degree in Environmental Science from UTSA. The learner must also fill out a waiver to work in the field.
-
The learner will complete a Lesson and Exam in Google Classroom and score a grade of 80 or above.
-
The learner will participate in a field workshop to collect data using two plant estimation techniques, the quadrat method for woody plants and the National Ecological Observatory Network (NEON) method for sampling plant diversity of herbaceous data. To receive the badge, the entire workshop will need to be attended.
-
Assignment 1 - The learner will calculate the density, relative density, basal area, relative basal area, frequency, relative frequency, and relative importance for sampled woodland area. They will also calculate sample adequacy. Finally, the learner will present this information in a form acceptable by the profession.
-
Assignment 2 - The learner will calculate the percent cover and diversity of herbaceous species and present the data in a form acceptable by the procession.
