Payment For Ecosystem Services: Rewarding The Landowner Who Conserves The Public Good, Steven H. Bullard, Sarah Fuller
Payment For Ecosystem Services: Rewarding The Landowner Who Conserves The Public Good, Steven H. Bullard, Sarah Fuller
Faculty Publications
It has been said that money doesn’t grow on trees, but any forest landowner or manager will tell you that’s not exactly true— especially when observing a harvesting operation or managing dues from your hunting lease. While timber production and recreation are the most frequently monetized services provided by forests, what about the other goods and services they provide on a continuing basis? Are you or other forest landowners in your area being monetarily rewarded for soil stability, flood control, water filtration, air quality, and the other critical services—known as ecosystem services—provided by forests?
Integrating Drone Technology With Gps Data Collection To Enhance Forestry Students Interactive Hands-On Field Experiences, Daniel Unger, I-Kuai Hung, Yanli Zhang, David Kulhavy

Undergraduate students pursuing a Bachelor of Science in Forestry (BSF) at Stephen F. Austin State University (SFA) within the Arthur Temple College of Forestry and Agriculture (ATCOFA) attend an intensive 6-week hands-on instruction in applied field methods. The second week of field station is focused on land measurement activities to introduce students to practical, hands-on, and technology based ways to survey forest boundaries. On Monday of the second week students are introduced to the concepts of how to use a handheld compass to navigate from point to point, use a consumer-grade handheld Global Positioning System (GPS) unit for collecting the …
Validating One-On-One Gps Instruction Methodology For Natural Resource Area Assessments Using Forestry Undergraduate Students, Daniel R. Unger
Validating One-On-One Gps Instruction Methodology For Natural Resource Area Assessments Using Forestry Undergraduate Students, Daniel R. Unger
Faculty Publications
Undergraduate students pursuing a Bachelor of Science in Forestry (BSF) at Stephen F. Austin State University (SFA) attend an intensive 6-week residential hands-on instruction in applied field methods. The intensive 6-week instruction includes learning how to use the Global Positioning System (GPS) with a Garmin eTrex HCx GPS unit to accurately calculate area. Students were instructed how to assess the accuracy of their GPS collected waypoints by calculating the Root Mean Square Error (RMSE) comparing their GPS collected area measurements with instructor on-screen digitized area. Student’s average area RMSE between digitized and GPS derived area was 0.015 hectares, whereas instructor’s …
Accuracy Assessment Of Perimeter And Area Calculations Using Consumer-Grade Gps Units In Southern Forests, Daniel Unger, I-Kuai Hung, Yanli Zhang, Jeffrey Parker, David Kulhavy, Dean W. Coble
Accuracy Assessment Of Perimeter And Area Calculations Using Consumer-Grade Gps Units In Southern Forests, Daniel Unger, I-Kuai Hung, Yanli Zhang, Jeffrey Parker, David Kulhavy, Dean W. Coble
Faculty Publications
Field foresters have long required a method of accurate measurement of perimeter and area during forest management activities. Perimeter and area assessments that can be derived from individual waypoints collected via global positioning system (GPS) units can be an expensive endeavor. A question of concern for practicing foresters is as the cost of GPS units increase does the accuracy of waypoints and any derived perimeter and area assessments also increase? This research evaluated whether the dynamic collection of waypoints using consumer-grade GPS units ranging from $50 to $700 provide a sufficient level of accuracy for the calculation of perimeter and …
Standardized, Cost-Effective, And Repeatable Remote Sensing Methodology To Quantify Forested Resources In Texas, Daniel Unger, James Kroll, I-Kuai Hung, Jeffrey M. Williams, Dean W. Coble
Standardized, Cost-Effective, And Repeatable Remote Sensing Methodology To Quantify Forested Resources In Texas, Daniel Unger, James Kroll, I-Kuai Hung, Jeffrey M. Williams, Dean W. Coble
Faculty Publications
A standardized remote sensing methodology was evaluated for its use in quantifying the forested resources of the state of Texas in a timely and cost-effective manner. Landsat data from 2002 were used to create a land cover base map encompassing a four-county study area in East Texas. Site-specific and non-site-specific accuracy assessments of the classified map indicate that overall the 2002 base map accuracy of 72.78% was within acceptable remote sensing standards for Landsat data and that forest cover types derived from 2002, 1987, and 1980 Landsat data were within 4.4, 0.5, and 7.4% agreement with Forest Inventory and Analysis …

The primary goal of many nonindustrial private forest (NIPF) landowners, forestry consultants, and timber industry professionals is to increase revenues from their forestland. Most often, increased revenues are a result of harvesting timber stands from the site. However, the chances of increased revenues can be greatly reduced if the stands are improperly managed or voluntary Best Management Practices (BMPs) guidelines are not followed.

Part I of this article covered the basics of compounding and discounting. You were introduced to forestry investment analysis. However, several complications were not discussed. What about inflation, taxes, and risk? Part II addresses basic complications. It also includes more detailed forestry investment analyses.
How To Evaluate The Financial Maturity Of Timber, Steven H. Bullard
How To Evaluate The Financial Maturity Of Timber, Steven H. Bullard
Faculty Publications
If you own merchantable timber, you face an important question on a continuing basis: "Should I sell my timber now or should I wait?" How you respond to this question involves many issues, of course, including stand conditions, site conditions, and other physical and biological considerations. For many landowners, however, financial considerations are also extremely important. In this article we discuss "financial maturity" as a specific tool that can be used to help evaluate timber harvest decisions.

Basic Concepts In Computer Analysis Of Forestry Investments, Steven H. Bullard, Thomas J. Straka
Faculty Publications
In the last 20 years alone, computer hardware and software developments have dramatically increased our ability to calculate financial criteria quickly and accurately. While these advances have dramatically increased our ability to calculate, they have not replaced the need to understand what is being calculated, or how the results should be interpreted and applied. Our objective in the present article is to provide background information for understandingthe "what" and "how" of computer applications for forestry investment analysis. We briefly discuss the most important financial criteria that are calculated by investment analysis computer programs; we also describe their recommended uses and …
Research Report No. 25, Frmps: A Forest Resource Management Planning Simulator For East Texas Pine Plantations, Tom Hartz
Informal Project Reports
FRMPS is designed to provide a landowner an opportunity to simulate the establishing, growing and harvesting of lob lolly pine ( Pinus taeda L.) and slash pine ( Plnus elltotti Engelm. ) plantations in East Texas. Also included in the model is a procedure to s1mulate the growing of an existing non-plantation with a future conversion to ptne plantet1on. The effect of different cash flows from various activities and operations is analyzed using net present value as the decision-making criterion. FRMPS runs on a Macintosh SE or 11 personal computer and requires STELLA FOR BUSINESS v. 2. 1 software.
Financial Maturity Of Timber And Maximum Net Present Values, Steven H. Bullard
Financial Maturity Of Timber And Maximum Net Present Values, Steven H. Bullard
Faculty Publications
Simple financial maturity guidelines recommend harvesting timber when its rate of value growth becomes less than or equal to the highest rate that can be earned in other investments of equal risk. Several authors have shown that fin ancial maturity guides are consistent with maximizing economic c riteria such as net present va lue , but their results are sometimes accepted by fore sters and land managers without being fully understood. In this article , financial maturity guides are derived in a way that is easily understood, simply by maximizing the present value of all future net income.
