The pilot reported that the turf airstrip had a "sunken area," which created a "ramp." During takeoff, the airplane encountered this portion of the airstrip and became "airborne prematurely." The airplane subsequently settled into ground effect; however, the left wing impacted a small tree near the end of the runway, and the airplane then pitched "downward and left," and the airplane was unable to maintain altitude. The airplane impacted a field off the end of the runway. The airplane sustained substantial damage to the wings and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
