Notes | Studied effects of the Apple Fire of August, 2002 on cutthroat trout populations in the North Umpqua River Basin. Cavitt Creek was the unburned control. Used fish scale growth rings to determine growth and metabolism. Water temperatures in the burned streams rose following the fire. Interestingly, trout grew more following the burn. "Despite extensive changes to the physical environment following the wildfire, fish responded to these new conditions and were resilient to disturbance over short time scales. In fact, low pre-fire water temperatures may have been a limiting factor in these streams and only following increases in water temperatures were fish able to exhibit elevated growth rates and achieve greater sizes."
