| Course ID: | FANR 3000-3000L. 4 hours. 2 hours lecture and 8 hours lab per week. | | Course Title: | Field Orientation, Measurements, and Sampling in Forestry and Natural Resources | Course Description: | Introduction to equipment used in the field to navigate across
the landscape and to measure a variety of natural resource
attributes. Basic statistical sampling techniques will be
reviewed and applied in the field to obtain information at a
desired level of precision and statistical confidence level.
Concepts will be presented in lecture and apply during field
labs. Field data will be summarized and evaluated to create
reports of field findings. | | Oasis Title: | FIELD MEAS | | Duplicate Credit: | Not open to students with credit in FORS 3000-3000L | | Prerequisite: | (Enrollment in Professional Program of WSFR) | Semester Course Offered: | Offered fall and spring semester every year. | | Grading System: | A-F (Traditional) |
| | Course Objectives: | By the end of the semester, students will have the following
skills.
A. Proficiency with navigation and map reading skills such that
they can traverse across multiple landscapes.
1. Read and use a range of map types.
2. Understand topography and its measurement.
3. Use and interpret aerial photographs at a basic level.
4. Conduct basic land surveys.
5. Understand scale and spatial relationships.
6. Use a hand compass to navigate cross-country,
triangulate locations on land and water, locate land ownership
lines, and record headings.
7. Use navigation-grade GPS receivers to navigate cross-
country and use mapping-grade GPS receivers to record position
data.
8. Know the components of legal property descriptions and
be able to look up and use deeds.
9. Create a proper and useful map of land and water
resources and features by hand and by the use of mapping
software.
B. Identify and use appropriate techniques for collecting,
analyzing, testing, and interpreting natural resource data.
1. Use appropriate field methods and equipment for sampling
terrestrial and aquatic habitats.
a. Be familiar with the proper application of and the
techniques associated with plot, point, line (distance), and
strip sampling to measure a variety of terrestrial and aquatic
features (stem density, height, average size, biomass per acre,
value per acre, fish or animal density, aquatic habitat
measurements, etc.) [Faculty from all majors are expected to
provide examples.]
b. Be aware of potential sources of measurement error and
bias and know proper measurement techniques to minimize error.
c. Understand the proper methods for summarizing field
data
from these measurement techniques, expanding estimates to a per-
acre or per-hectare basis, and reporting it appropriately to
users.
d. Know the proper use and care of equipment used to take
common measurements in the field of a variety of natural
resources.
e. Be able to design a simple multi-resource inventory for
a forested property for a target level of estimation for a
given
stand measure.
2. Use computers and software with proficiency
a. Know how to use Word to create a memorandum and reports
with proper formatting and referencing of figures, tables, and
literature.
b. Use Excel to summarize data using statistical and
graphing features including appropriate formatting, effective
use of relative and absolute addressing, and clear
documentation
of spreadsheet contents.
c. Learn how to obtain GPS base station data, use it to
differentially correct GPS field data, and produce a map for
export to ArcView.
3. Be able to analyze natural resource data and apply
appropriate statistical techniques. [Faculty from all majors
are expected to provide examples.]
a. Sampling/populations (nesting, stratification,
randomization)
b. Descriptive statistics (mean, sdev, cv, stderror,
bounds, etc.)
c. Estimation of population parameters and error bounds
d. Hypothesis testing -- testing for differences and
change.
e. Understanding variability, reliability – confidence in
the numbers, confidence limits, measurement error, sample size
requirements.
f. Use simple linear regression to fit a line to paired
observations.
g. Understand how field data is used an inputs to
management models such as habitat suitability indices or growth
& yield models.
C. Communications
Students will have a written lab reports during most weeks of
the semester (8-10). These will be in the form of a one-page
memorandum written to a client or job supervisor and will
report
findings from field measurements in clear language with
appropriate numerical reporting. | | Topical Outline: | Introduction to the need for measurements of natural resources

Planning to conduct a multi-resource inventory on a
property
Tentative Lab Outline: These will attempt to use examples,
applications, and datasets from all WSFR disciplines as
provided
by the faculty.
• Measurement of distance and slopes, introduction to
compass and pacing
• Introduction to topographic maps and coordinate systems
• Measure the direction and distance of each side of a
closed traverse, practice pacing
• Calculate area of a measured traverse using each of
three techniques and draw a map
• Cross-country navigation with compass and GPS receiver
• Pacing practical quiz, collect position data with a
mapping-grade GPS receiver
• Visit UGA Map Collection and Athens-Clarke County land
records
• Download and differentially correct GPS data, export to
ArcView format, mission plan
• Introduction to Excel – data types, functions, cell
addressing, formats, graphs
• Vegetation measurements and equipment – size, height,
age, density per unit area, mass
• The following techniques are used in the field followed
by summary of the data with Excel. We start using a technique
on a single resource and move into using multiple techniques on
multiple resources during a single inventory.
o Fixed-area plots and quadrats for density & frequency
of
occurrence
o Sampling by vegetation size class
o Plotless sampling with prisms and point-centered
quarters
o Understory/regeneration sampling, % ground cover, %
canopy cover
o Line transect and strip sampling for terrestrial woody
debris / fuel loads
o Aquatic sampling in pond environments.
o Aquatic sampling in stream environments with strip
sampling for woody debris
• Linear regression – Fitting lines to paired
measurements
from the field
• Prepare a multi-resource inventory for a portion of
Whitehall Forest
• Exams will be conducted during lab sessions.
Communications: Students will have a written lab reports
during
most weeks of the semester (8-10). These will be in the form
