were givens 1 to 3 value with the first ranking <br />receiving three points, second ranking receiving two <br />points and the third receiving one point. Several ques- <br />tionahad positive or negative effects response options. <br />Qualitative answers were grouped into categories to <br />reduce the data to a manageable amount. Correlation <br />analysis and categorical t-testa were performed on <br />selected information in the data. <br />BAER spending and treatment costa were trans- <br />formed into similar unite (i.e., hectares or acres) and <br />adjusted for inflation based on consumer price index to <br />1999 dollars (Federal Reserve Bank 1999). This made <br />meaningful comparisons possible for analyzing <br />spending trends. Treatment costa were obtained from <br />the final Burned Area Report forms and were assigned <br />to the year of the fire. <br />Monitoring Reports-Because most of the infor- <br />mation in monitoring reports was qualitative in na- <br />ture, excerpts from reports were entered into the <br />database referenced to specific fires. Other excerpts <br />were included in the general comment fields. Quan- <br />titative information was tabulated by hand sepa- <br />rately from the main database because of its diverse <br />nature. <br />Results <br />Overview of Data Collected <br />Data were collected from 470 Burned Area Reports <br />and 98 interviews. The results represent our beat <br />estimate of the types and amounts of BAER treat- <br />ments used and their attributes for the past 3 decades <br />in the Forest Service. However, we were not able to <br />collect all possible Burned Area Reports. Regions 1 <br />and 3 are nearly complete data seta, whereas Re- <br />gions 2, 4, 5, and 6 have missing results, especially <br />from the 1970'x and 1980'x, because materials had <br />been archived and could not easily be accessed. There- <br />fore, all dollar and area totals reported are at beat <br />minimum estimates. <br />While our goal was to collect information on BAER <br />treatment effectiveness, we also acquired a vast data- <br />base of information on BAER project and no-action <br />fires from the Burned Area Reports. These report data <br />allowed us to tabulate and examine the various pieces <br />of information that make up the BAER evaluation. <br />Over the past 3 decades, more than $110 million was <br />spent in total on emergency rehabilitation that in- <br />volved the Forest Service. Of that, about $83 million <br />came from National Forest Syatema (NFS) to treat <br />4.6 million ac (1.9 million ha) of a total of 5.4 million ac <br />(2.2 million ha) from BAER project foes. About 72 <br />percent of the total area treated was National Forest <br />System lands. The remainder was on other Federal <br />agency, State, and private lands. <br />Of the 470 fires for which Burned Area Reports were <br />prepared, 321 had BAER treatments recommended. <br />The rest (148) were fires for which no emergency was <br />identified and no BAERtreatment requested. Seventy <br />two of the fires were less than 1,000 ac (400 ha), 153 <br />fires were between 1,000 to 10,000 ac (400 to 4,050 ha), <br />and 96 were greater than 10,000 ac (4,050 ha). <br />Expenditures for BAER treatments have increased <br />substantially, especially during the 1990'e (fig. 1). <br />There were several large fires that represent a major- <br />ity ofthe spending in the 1990'a ($48 million), includ- <br />ing the Rabbit Creek, Foothills, and Eighth Street <br />fires on the Boise National Forest in Idaho and the <br />Tyee Creek Complex on the Wenatchee National For- <br />est in Washington (table 9). Regions 4, 5, and 6 ac- <br />counted for 86 percent of the BAER spending from <br />1973 to 1998 (fig. 2). Total acres burned by year (fig. 3) <br />shows a trend aimilarto that for spending especially in <br />the 1990'x. In terms ofcoat per acre burned, the bigfire <br />years do not always coincide with the greatest amount <br />per acre (hectare) spent on BAER treatments. In 1989 <br />for example, an average of $67 ac 1 {$165 ha 1) was <br />spent on 55,000 National Forest System ac (22,300 ha) <br />burned. When 616,000 National Forest System ac <br />(249,00 ha) burned in 1996, only $16 ac 1 ($40 ha 1) <br />was spent (fig. 4). <br />Fire Severity <br />Part of the Burned Area Report form contains infor- <br />mation on percent of the total burned area in low, <br />medium, and high fire "intensity."
