The objective was to obtain and provide reliable data and informa- tion on acreages burned and tons of fuel burned per acre for each of the categories in the approximately 3,100 counties and other jurisdictional entities in the country. The data and information was obtained from the U.S. Forest Service; Bureau of Land Management; Bureau of Indian Affairs; and the various state forestry, agricultural, and environmental agencies. A limited number of industry (trade associations), academic, and independent personnel were contacted for specific information. The information retrieved were evaluated and the most reliable selected for use. Where source data values conflicted, adjustments were made. Estimates were derived for states on the basis of land area, forest area, farm and crop area, and verbal descriptions of the fire activity. No estimates were made where no data whatsoever was available. The pertinent data were entered on area source coding forms provided by the Project Officer and using his data entry guidelines. These completed source coding forms were then VI ------- forwarded to the Project Officer for examination, comments, corrections, and final use. This report summarizes the information on the area source coding forms for 55 states and territories, the information source or sources, and if an estimating and/or proportioning method were utilized. The state forest wildfire information was adjusted to an average 10-year value as calculated from the Federal "Wildfire Statistics" which is published annually by the U.S. Forest Service, Division of Cooperative Forest Fire Control. County breakdowns for the states were either supplied by state personnel or estimated on the basis of verbal or pub- lished references to the specific burning practice in that state. VI1 ------- AN INVENTORY OF EMISSIONS FROM FOREST WILDFIRES, FOREST MANAGED BURNS, AND AGRICULTURAL BURNS INTRODUCTION The objective of this project was to obtain and provide reliable data and information on acreages burned and tons of fuel burned per acre for each of the approximately 3,100 counties and other jurisdictional entities in the 55 states and territories. This information will then be utilized in conjunction with emission factors developed in a previous pro- gram in order to obtain air pollutant emissions information from forest wildfires, forest managed burns, and agricultural burns. ------- DISCUSSION BACKGROUND The National Air Data Branch is charged with the responsi- bility of collecting, analyzing, and storing air pollutant emissions information on sources located in the 55 states and territories. Area source inventories have been made for each state and territory. Only 11 contain data on emissions from forest wildfires, forest managed burns, and agricultural burns. To complete the area source inventories, reliable data on emissions and their related information (acreages burned and tons of fuel burned per acre) is necessary for each of the approximately 3,100 counties and other jurisdictional entities in the states and territories. This will then supplement and refine the National Emission Data Bank (NEDB) county area source inventories. OVERVIEW OF METHODOLOGY The data and information was obtained from the U.S. Forest Service; Bureau of Land Management; Bureau of Indian Affairs; and the various state forestry, agricultural, and environmental agencies. A limited number of trade associations, academic, and independent personnel were contacted for specific fire information. The data and information were obtained as publi- cations, copies of annual and summary reports, copies of survey ------- reports, state emission reports, and verbal reports. The data were evaluated and the most reliable selected for use. When necessary, adjustments and proportions were utilized to equate federal and state values. In many states where agriculture is economically important and/or geographically distant from urban centers, there was a distinct lack of know- ledge or information on forestry or agriculturally related burning practices, Many state environmental agencies were unaware of agricultural or forest burning practices in their state. Where possible, estimates were made where information was not available but some base could be obtained to make an estimate. The pertinent data were entered on area source coding forms. The area coding forms, background coding information, and data entry guidelines were provided by the Project Officer. The completed source coding forms were forwarded to the Project Officer for examination, comments, and final use. This report summarizes information on the area source coding forms, the information source or sources, and if an estimating and/or proportioning method was utilized. The state forest wildfire information was directly related to an average 10-year value as calculated from the Federal "Wildfire Statistics1 which is published annually by the U.S. Forest Service, Division of Cooperative Forest Fire Control. County breakdown for the states were either supplied by state personnel or estimated on the basis of verbal or published references of the burning practices in that state. ------- INFORMATION AND DATA SEARCH The information search was initiated in several directions. The literature sources were reviewed for information on forest wildfires, forest managed burning, and especially agricultural burning activities. Letters requesting information were sent to distant areas (non-continguous United States) where tele- phone contact would be difficult. Telephone calls were made to contacts established in a previous program for further informa- tion, referrals, and new sources of information. When necessary, various state environmental, forestry, and agricultural agencies were contacted in order to obtain additional needed information. Personal interviews were limited when it was discovered that no single source had enough available information to war- rant the travel expenditure. It was estimated that a minimum of two or three on-site personal interviews were necessary for each state in order to obtain the desired information. There was also no way of being assured that the information, if present, would be available or given freely. Therefore, the bulk of the information requests were made over the telephone with a follow-up letter when requested or suggested. DATA RETRIEVAL AND EVALUATION If possible, the acres burned and tons of fuel burned per acre in each of the three categories of forest wildfires, for- est managed burns, and agricultural burns were obtained for each of the counties or fire districts in the state. If data was available, a five-year or 10-year summary was made in order to average the variable burning behavior; otherwise, data for ------- an average year (typical) or a record of a recent year was used. A study of a state's vegetation-topography-fire record was helpful. A working summary sheet was prepared for each of the 55 states and territories plus a cumulative state total tally. The data were evaluated on the basis of number of years record, county or district breakdown, type of vegetation, and complete- ness of state coverage. If the fire record was for a number of years, the average was taken. In the wildfire category, this average was apportioned over the state or proportioned to equal the federal 10-year average for the state, ilany states do not have records on agricultural burning activities or forest managed burns. Some states have very poor records on wildfire activities. Lastly, fuel consumption in a fire (tons of fuel burned per acre) is an unknown data for most of the states in all three categories. Regional results of a previous study were utilized to obtain county and state values for these unknowns. In states exempting agricultural burning from air quality regulations in addition to states where officials were unaware of burning activity as part of a standard cultural practice, no numerical value or estimates were made and the corresponding appropriate spaces in the area coding forms were left blank. ------- RESULTS Area source coding forms were filled out for all 55 states and territories; with the exceptions of Arizona, Nevada, and Oregon. Results from these three states had been placed in the National Emission Data Bank (NEDB) country area source inventories previous to the start of this program by other contractors. The following is a brief reference to the major information sources in the respective states and territories. Table 1 summarizes the data which was collected. ALABAMA The Alabama Forestry Commission provided a five-year (1969-73) data for wildfire acreage burned by country. The average was calculated and then proportioned to equal the 10-year average Federal Wildfire Statistic for Alabama. The prescribed burning and the agricultural burn data were esti- mates of these burning activities obtain in several surveys made by the U.S. Forest Service, Southeastern Area, State and Private Forestry. County breakdowns were estimated on the basis of forestry and agricultural activities in the state. Fuel loadings in all three categories were estimates prepared in an earlier study. ------- 1 (Code 01 i 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 : 17 18 19 20 21 22 23 24 • 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 , 42 j 43 ! 44 I 45 46 47 48 49 50 51 52 53 54 ! 55 1 Table 1.

The basic publication used was: Barney, Richard J. , "Interior Alaska Wildfires, 1956-1965", U.S. Dept. of Agriculture, 1969. Prescribed fire activity is now being experimentally carried out in the Interior using the Australian Bushfire system. No agricultural burning activity was noted. Fuel loadings were estimates obtained in an earlier study. ARIZONA Arizona state personnel reported that their data was already in NEDS and no further up-date has been made, ARKANSAS The Arkansas Forestry Commission provided wildfire statis- tics for five years (1969-73) for their administrative districts A map was provided to indicate the counties contained within each district. An apportionment was made for each county in each administrative district. This estimate was then propor- tioned to equal the 10-year average of the Federal Wildfire Statistices. Prescribed burning data were estimates from a survey made by the U.S. Forest Service, Southeastern Area, State and Private Forestry. No agricultural burning estimates were obtained. Fuel loadings were estimates prepared from an earlier study. CALIFORNIA California provided a three inch stack of computer printout on their burning activities. Their data were complete and 8 ------- covered all aspects of burning for 1973. However, their wild- fire data was adjusted proportionately to equal the 10-year average for California as obtained from the Federal Wildfire Statistics. COLORADO Colorado is now in a period of adjustment in that they are compiling their state information, Wildfire statistics, pre- scribed burning, and agricultural burning take place but no agency or group is aware of the extent of burning or has res- ponsibility over it. The wildfire statistics for the state were estimated on the basis of verbal descriptions, land acre- ages, and the forested acreages. Fuel loadings were estimates prepared in an earlier study. CONNECTICUT The State of Connecticut, Department of Environmental Protection, provided data on 1972 wildfire acres burned per town per county. These were proportioned to the 10-year average burn which took place all on state and private lands. Prescribed burning and agricultural burning were prohibited in Connecticut. DELAWARE The 10-year average wildfire acres burned were obtained from the Federal Wildfire Statistics. State breakdown of the various categories were provided by the Department of Natural Resources and Environmental Control. Their categories of forest fires, marsh fires, and prescribed forestry burning were stated to be fairly reliable whereas educated guesses were used for agricultural burning. Their fuel consumptions were used ------- in the coding form. DISTRICT OF COLUMBIA Data was verbally provided by the Fire Prevention Division of Washington, D.C. Most of the wildfires were small acreages in trees, brushes, and grass along the highways and in the parks. Managed burning and agricultural burning were prohibited, FLORIDA The Division of Forestry, Florida Department of Agriculture and Consumer Services, provided extensive data on wildfire and forestry burning. Data processing equipment will provide more information later in the year on all open burning that the Division has jurisdiction over especially agricultural burning. At present, only the cane fires were reported here since other agricultural burning data were not available. GEORGIA The Georgia Forestry Commission provided information on open burning in forest and agricultural land. Their district data was apportioned over the counties. The wildfire statis- tics were proportioned to equal the Federal Wildfire Statistics. The prescribed burning statistic was proportioned to equal the average of three surveys taken by the U.S. Forest Service, Southeastern Area, State and Private Forestry. Fuel loadings from an earlier study were utilized for this report. HAWAII Hawaii's wildfire statistics were obtained by apportioning the 10-year average from the Federal Wildfire Statistics to the various county land acreages. No prescribed burning activity 10 ------- took place. Agricultural burning takes place with the burning of sugar cane in all four counties and the burning of pineapple plant residues in Honolulu and Maui counties, Agricultural fuel loadings were obtained verbally from cane industry person- nel, the Hawaii State Department of Health, and cultural practices IDAHO Idaho statistics were obtained by estimates and propor- tioning of data obtained from the Project Officer. The wild- fire statistics were proportioned to equal the 10-year average Federal Wildfire Statistics. The forest managed burning and the agricultural burning were apportioned from a combined managed burning total on the basis of fuel loading. ILLINOIS Illinois wildfire statistics were obtained by apportioning the 10-year average Federal Wildfire Statistics over the forested area of the state. Forest managed burning is nil for the state. Agricultural burning is exempt from regulation but does not take place as a standard cultural practice. INDIANA Indiana wildfire statistics were obtained by apportioning the 10-year average Federal Wildfire Statistics over the forested area of the state. No forest managed burning takes place. Agricultural burning is exempt from regulation. IOWA The State Conservation Commission provided information on the wildfire history for the period 1966-1973 in the counties of Iowa. Forest managed burning is not a practice, Agricultural 11 ------- burns for stubble removal and fence row clearing is diminishing, but no estimates were available, KANSAS The wildfire, forest managed, and agricultural burn sta- tistics for the state were prepared and apportioned on the basis of verbal descriptions of its extent and locations, Personnel in Air Quality and Conservation as well as Kansas State University provided the verbal descriptions, KENTUCKY The Division of Forestry, Department of Natural Resources and Environmental Protection, provided wildfire data covering the five-year period 1969-73, Forest managed burning is nil and no estimates were available for agricultural burning since it is not prohibited. Fuel loadings were estimates from an earlier study. LOUISIANA The Louisiana Forestry Commission provided the 10-year wildfire statistics (1964-73) and the forest managed burning information (1970). The agricultural burning information was obtained from the American Sugar Cane League in New Orleans„ MAINE The Bureau of Forestry, Department of Conservation, pro- vided the wildfire statistics for a 10-year period (1964-73). Forest managed burning is not practiced in this state. The agricultural burn information was verbally received from the Department of Agriculture. 12 ------- MARYLAND Data and information were obtained from the Bureau of Air Quality and the Forest Service of the Maryland Department of Natural Resources. Verbal estimates of fuel loading were ob- tained with references to Delaware (6 tons/acre) and to West Virginia (9 tons/acre), A calculated state average of 7„1 tons per acre were obtained for the state. Forest managed burning is not practiced in the state. Marsh grass is burned annually for muskrats in one county, MASSACHUSETTS Forest wildfire data for a representative year (1972-73) by fire protection districts were provided by the Bureau of Forest Fire Control, Department of Natural Resources. The statistics were proportioned for the counties and equated to the federal statistics. Forest managed burning is not prac- ticed and no estimate was possible for agricultural burning activity. Fuel loading was an estimate obtained in an earlier study. MICHIGAN Wildfire (1972) and forest managed burn (1973) statistics were provided by the Forest Fire Division, Department of Natural Resources, The wildfire data closely represents the last five- year average and were equated to the federal statistics, Managed burn data were initiated in 1973, No estimate was possible for agricultural burning activity Fuel loadings were verbal assents to estimates prepared in an earlier study. 13 ------- MINNESOTA Minnesota is also undergoing adjustment in compiling state information, The wildfire statistics for the state were appor- tioned on the basis of verbal descriptions of its extent and locations in the state. No estimates were obtained of the extent of forest managed or agricultural burning. Fuel loadings were estimates prepared in an earlier study. MISSISSIPPI The Mississippi Forestry Commission provided county data for five years (1969-73) for wildfires, a statewide estimate for prescribed forestry burning, and a fire protection dis- trict map of the state. Agricultural burning statistics were estimates from the U.S. Forest Service, Southeastern Area, State and Private Forestry. Wildfire data was proportioned to equal the federal statistics whereas forest managed burns and agricultural burns were estimated on the basis of forestry and agricultural activities in the state. Fuel loadings in all three categories were estimates prepared in an earlier study, MISSOURI The Department of Conservation provided data and informa- tion for a six-year period (1967-72) for wildfires. Their fire statistics are based on protection districts and covers only half of Missouri. Averages were apportioned to counties in each district. No estimates were possible for forest managed and agricultural burns since minimum restrictions are placed on these activities. 14 ------- MONTANA Estimates of wildfire and forest managed burns were made on the basis of verbal information and literature sources. Much of the information is not divulged, expecially by the large land owners. Apportionment of values were made on the basis of land, forest, and farm acreages. References were made to the personnel at the University of Montana having access to but do not have available records of slash burning activity. No estimates could be made on agricultural burn activity because less was known of this practice. NEBRASKA The Federal Wildfire Statistics for the state was appor- tioned on the basis of land acreage and verbal descriptions of its extent and locations in the state. Fuel loading was esti- mated from a verbal description of the fuel type in the state. No forest managed burns were reported. No estimates were available for agricultural burning activity. NEVADA Nevada reported that their data was collected by another contractor and placed in NEDS. Up-dating of information has not taken place since that time, NEW HAMPSHIRE The Division of Resources Development of the Department of Resources and Economic Development provided data and informa- tion on wildfires. Since data was on a fire district basis, the values were apportioned to the various counties. Forest managed and agricultural burning, although permitted, was nil. 15 ------- NEW JERSEY The Federal Wildfire -Statistics for the state and the state estimate of forest managed burns were apportioned to the counties on the basis of land area and verbal descriptions of its extent and location. Fuel loadings varied from the Piedmont region in the north to the Coastal Plains by the ocean. No agricultural burning was reported, NEW MEXICO The Federal Wildfire Statistic for the state was appor- tioned to the counties on the basis of land area, forested area, and verbal descriptions.

NEW YROK The Department of Environmental Conservation provided data on wildfires in the various counties. The fuel loading was an estimate from an earlier study. Forest managed and agricultural burns were nil for the state. NORTH CAROLINA The Federal Wildfire Statistics was apportioned to the counties on the basis of data and information provided by the Department of Natural and Economic Resources (Forest Service) for an 11-year period (1963-73). The forest managed and agri- cultural burn data were estimates obtained in several surveys made by the U.S. Forest Service, Southeastern Area, State and Private Forestry. The apportionment was based on census values, land area, forest area, and verbal descriptions. Fuel 16 ------- loadings were estimates derived in an earlier study. NORTH DAKOTA The Division of Environmental Engineering, Department of Health, and the Bureau of Indian Affairs provided information on burning activities in the state. The wildfire and managed burning statistics were apportioned on the basis of land area, forested area, and verbal descriptions.

Forest managed burns were not conducted in this state. No estimates were possible for agri- cultural burning activity. The fuel loading was an estimate from an earlier study. PUERTO RICO Information on fire activity in Puerto Rico was provided by the Environmental Quality Board. Forest wildfires and managed burns were rare due to the small acreage and location in the humid zones. Agricultural burns, especially sugar cane, is dominant. A breakdown of sugar cane burning activity on the basis of sugar mill location and U.S. Census Bureau publi- cations were used in apportioning agricultural burns. Fuel loading was estimated on the basis of tonnage of cane harvested per acre and type of harvesting practice (field). RHODE ISLAND The Federal Wildfire Statistics for the state was appor- tioned on the basis of a verbal description of its extent and location. Approximately two-thirds of the fires occur in Kent and Washington Counties. Fuel loadings in the state range from 4-10 tons per acre (7 tons/acre average). Forest managed and agricultural burns are prohibited. SOUTH CAROLINA The State Commission of Forestry provided data on wildfires and forest managed fires for the five-year period 1969-73. 18 ------- The forest type and terrain is similar to North Carolina's. No estimate was available on the extent of agricultural burning Fuel loadings were estimates prepared in an earlier study. SOUTH DAKOTA The Federal Wildfire Statistics for the state was appor- tioned on the basis of verbal descriptions of its extent and locations. The Black Hills region accounts for 85% of the acreage burned. No estimates were obtained on the extent of forest managed or agricultural burning since these activities are permitted. Comments were received that not much of these activities do take place. TENNESSEE The Division of Forestry, Department of Conservation, provided data on forest wildfires for the period 1960-73. The data was apportioned to equal the 10-year federal wildfire average for acres burned. No estimates were available for forest managed and agricultural burns. The wildfire fuel loading was an estimate derived in an earlier study. TEXAS The Texas Forest Service provided data on various fire activities in the state. The wildfire data were proportioned to each county in the district on the basis of acreage and equated to the federal statistics. The forest managed burns were similarly equated to the survey estimates of the U.S. Forest Service, Southeastern Area, State and Private Forestry. Agricultural burns are prohibited except for variances granted to the flax and sugar cane industries. However, these 19 ------- year-to-year variances were scheduled to end. Fuel loadings were estimates from forestry personnel and related to an earlier study. UTAH The Federal Wildfire Statistics for the state was appor- tioned on the basis of land area, forest area, and verbal des- criptions of its extent and location. Fuel loading was an estimate derived in an earlier study. No estimate was possible of forest managed and agricultural burns. These activities were quoted to be limited in scope. VERMONT The Federal Wildfire Statistics for the state was appor- tioned on the basis of verbal descriptions of its extent and location. Fuel loading was an estimate derived from an earlier study as it related to fuel models for the area. Forest managed burns are nil and only a small amount of agricultural burning takes place in Addison County. VIRGINIA The Division of Forestry, Department of Conservation and Economic Development provided data and information on forest wildfires (five-year average) and on forest managed burns (1972) Estimates of the tons of fuel consumed per acre were supplied for each type of burn activity. No estimates were available for agricultural burn activity. WASHINGTON The Department of Ecology and the Department of Natural Resources provided emission and burning data for the state of 20 ------- Washington. Supplemental information was obtained from another contractor working for Region X. Fuel loadings were estimates from data received and from a previous study. WEST VIRGINIA The Department of Natural Resources provided their wild- fire statistics for the period 1951-73. Their data was propor- tioned to equate to the federal 10-year wildfire average. The fuel loadings varied from 9 to 15 tons per acre, westward, and averaged 12 tons per acre for the state. Forest managed and agricultural burns were nil for the state. WISCONSIN The Department of Natural Resources provided wildfire data by county for the period 1964-73. The 10-year average was then adjusted slightly to equal the federal 10-year average for the state. The fuel loading was an estimate obtained in an earlier study without undue oral objection. No estimates were made of forest managed and agricultural burns since these occur without documentation or as a standard cultural practice. Efforts are being made to centralize record-keeping. WYOMING The Federal Wildfire Statistics for the state was appor- tioned on the basis of land area, forest area, and verbal des- criptions of its extent and location. Forest managed burning is nil on state and private lands whereas the National Park Service has a "let burn policy" in the area. No estimate was available for agricultural burning activity. 21 ------- AMERICAN SAMOA No estimates were possible, although the climatic condi- tions, geographic location, and vegetation types leads one to presume that burning activity is nil in this area. GUAM Written communication was received that these burning activities do not take place with any degree of concern. VIRGIN ISLANDS Verbal communication and literature references indicate that with the phasing out of the sugar cane industry, these burning activities are nil in this area. 22 ------- CONCLUSIONS The project goals of obtaining the best available data and information on emissions related statistics on forest wild- fires, forest managed burns, and agricultural burns were accomplished. The results of the information search and retrieval were evaluated and the most reliable selected for use. Where pos- sible, estimates were prepared for geographical areas presenting some indication of these burning activities. These estimates were based on land area, forested area, farm and crop areas, and some verbal description of the extent and location of the burning practice. No estimates were possible for areas where no available data, reference, or information were present to connect or relate to a burning activity. The values reported in the area coding forms and sent to the Project Officer are presently the best available and most reliable. 23 ------- RECOMMENDATIONS FOR FUTURE WORK Since the statistics are present-day values of past activities, periodic review and up-dating of information are recommended. This periodic activity will also extend the in- formation base to cover geographic areas where no estimates are presently available. Additional costs in time and money will be required for on-site surveys for some states where information is scattered, not kept, nor recorded. Another recommended area of study is the use of present statistics to extrapolate future burning activity; as a guide to control and modification of some burning practices; and finally to aid state and local authorities to understand these air pollutant sources. 24 ------- ABSTRACT This project was conducted to complete the area source inventories on emissions from forest wildfires, forest managed burns, and agricultural burns for each of the 55 states and territories. Reliable data and information on acreages burned and tons of fuel burned per acre were obtained for each of the approximately 3,100 counties and jurisdictional entities in the country. Literature searches, letters, telephone calls, and personal contacts were used in obtaining the results. The most reliable data was selected and entered on NEDS area source coding forms under the guidelines of the Project Officer for inclusion in the NEDB. Presently, the values obtained are the best and most reliable for these burning activities. No estimates were recorded for locations that had no available data or information. 25 ------- TECHNICAL REPORT DATA (I'li'use read iHZlructions on the reverse before completing) 1 REPORT NO LPA-4bU/3-74-062 4 TITLfc AND SUBTITLE Emissions Inventory From Forest Wildfires, Forest Managed Burns, and Agricultural Burns. 3 RECIPIENT'S ACCESSION-NO. 5 REPORT DATE November 1974 6.
