TOPIC: REVEGETATION PRODUCTIVITY MEASUREMENTS FOR PHASE III BOND 

RELEASE

INQUIRY: Federal regulations [30 CFR 816.116(a)(1)] require statistically valid sampling 

techniques for measuring successful revegetation; however, nowhere in the federal regulations 

does it indicate what methods may be used to measure vegetative ground cover, number of trees 

per acre, etc. Please conduct a survey to determine what production testing methods other states 

are proposing to use to measure revegetation success for final bond release. 

SEARCH RESULTS: A questionnaire was prepared to be used in canvassing IMCC members. 

Responses to initial calls indicated that other states also were seeking information on OSMapproved statistically valid sampling techniques for measuring successful revegetation. As a 

result, the survey was foreshortened when Pennsylvania produced the OSM methodology report, 

Virginia produced the Raelson-McKee study and Kentucky provided its memorandum on 

sampling techniques recently submitted to OSM. Copies of Federal Register notices which 

discuss both federal rules and approval or disapproval of state program amendments are also 

attached. 

METHODOLOGIES

"An Evaluation of Methods for Measuring Ground Cover for Reclamation Bond Release",

Office of Surface Mining Reclamation and Enforcement, Eastern Field Operations (January, 

1987).

The report provides an evaluation of the following eight methods of determining ground cover 

percentage:

1. Line-Frame 

2. Line-Point 

3. Diagonal Line 

4. Milacre Circle 

5. Farmer et al. 

6. Modified Rennie-Farmer

7. Notched Boot 

8. Raelson-McKee 

"Measurement of Plant Cover to Evaluate Revegetation Success", J.V. Raelson and G.W. 

McKee (January, 1982) [Agronomy Series 67, Department of Agronomy, Pennsylvania State 

University]. 

According to Raelson and McKee, methods for measuring vegetative cover should meet three 

requirements:

1. They must be simple. 

2. They must be precise and repeatable. 

3. They should provide a statement of statistical error. 

Along with the measurement methods listed below, the report discusses selection of sample 

points:

1. Visual Estimation 

2. Quadrat Sampling 

3. Crown Diameter 

4. Line Intercept 

5. Point-Frequency 

"Field Sampling Techniques for Determining Ground Cover, Productivity, and Stocking 

Success of Reclaimed Surface Mined Lands", Technical Reclamation Memorandum # 19, 

Kentucky Department For Surface Mining Reclamation and Enforcement (June 28, 1991).

Kentucky's report covers Parallel Transect and Angular Transect as methods for determining 

observations points for collecting vegetation data, productivity determination and sampling for 

measuring the success of:

1. Ground Cover 

2. Tree and Scrub Stocking 

3. Row Crops 

4. Pastureland and Cropland 

5. Prime Farmland 

REGULATORY HISTORY

The following Federal Register preambles to proposed and final federal rules on revegetation 

success (816.116/817.116) are enclosed to provide background information:

44 FR 14902 (MARCH 13, 1979). Permanent Program Preamble - Final Rule. 816.116 

Revegetation: Standards of success.

45 FR 51547 (AUGUST 4, 1980). Notice of suspension and statement of policy regarding 

effect on State programs. 

47 FR 12596 (MARCH 23, 1982). Proposed rule. Revegetation. 

Among other goals, the proposed rule would broaden the approaches acceptable for determining 

the success of revegetation. 

48 FR 40140 (SEPTEMBER 2, 1983). Final rule. Revegetation.

The revision of the federal rules was "not a weakening of revegetation requirements but reflects 

that the rules are designed to account for regional diversity in terrain, climate, soils, and other 

conditions under which mining occurs."

51 FR 41952 (NOVEMBER 20, 1986). Final rule; suspension. Compliance with court order.

52 FR 28012 (JULY 27, 1987). Proposed rule. Revegetation.

53 FR 34636 (SEPTEMBER 8, 1988). Final rule. Revegetation.

STATE PROGRAM AMENDMENTS AND GUIDELINES

Federal Register preambles for Virginia, Ohio and Louisiana are also attached. In these 

preambles, OSM discusses the specific elements of the state methodology or techniques for 

measuring revegetation success and why they do or do not comport with the federal regulations.
