Oberheu, and Johnston (1982). Fuel plots were located 

 randomly within the stands used for upland and ravine 

 vegetative analysis, rather than randomly across the en- 

 tire burn. Fuel data were taken for all upland and ravine 

 stands in 1978 and 1979 and for stands 2, 3, 4, 5, 9, 13, 

 14, 15, 16, 17, 18, 21, 24, and 26 in 1980. Fuel loading 

 sample plot data were analyzed by the USDA Forest 

 Service FUELS computer program (Brown, Oberheu, and . 

 Johnston 1982). 



Results of fuel study. Fuel loading results for both the 

 ravine and upland sites are presented in table 10. The 

 results show little change in fuels during the first 3 



postfire years. Where possible the same plots were used 

 all 3 years: however, it was not always feasible to 

 relocate the exact plots. Some variation in loads between 

 years can be attributed to the differences between plots. 

 There does appear to be a sUght but definite increase in 

 the greater-than-3-inch-sound category, probably caused 

 by falling fire-killed trees. The decrease in ravine duff in 

 1980 was caused by the omission of a wet, lightly burn- 

 ed ravine area with high duff levels. The drop in upland 

 duff in 1979 can not be explained. The seeded grasses 

 have contributed to a rapid increase in the grass and 

 forb category and, following the first year, in the dead 

 grass and forb category.
