Abstract
Highresolution charcoal and pollen analyses were used to reconstruct a 4600yrlong history of fire and vegetation near Taylor Lake in the wettest forests of coastal Oregon Today fires in these forests are rare because the season of ignition does not coincide with months of dry fuels From ca 4600 to 2700 cal yr BP fire episodes occurred at intervals of 140±30 yr while forest vegetation was dominated by disturbanceadapted taxa such as Alnus rubra From ca 2700 cal yr BP to the present fire episodes have become less common occurring at intervals of 240±30 yr and firesensitive forest taxa such as Tsuga heterophylla and Picea sitchensis have become more prominent Fire occurrence during the midHolocene was similar to that of the more xeric forests in the eastern Coast Range and suggests that summer drought was widespread After ca 2700 cal yr BP a decrease in fire episode frequency suggests that cooler conditions and possibly increased summer fog allowed the establishment of presentday Picea sitchensis forests within the watershed These results provide evidence that fire has been an important disturbance agent in the Coast Range of Oregon and variations in fire frequency and climate have led to the establishment of presentday forests
