The pilot reported that he was making a full stop at the 2,300 foot grass airstrip. He reported that the airplane touched down indicating about 70 mph. An inspection of the aircraft and accident site revealed that the aircraft first touched down slightly right of centerline at about 1000 feet from the approach end of runway 36. The track of the airplane indicated that the aircraft veered left heading straight to the point where it impacted the tree. About 400 to 450 feet after touchdown, the left flap made contact with the grass airstrip. A 250 to 300 foot gouge in the turf was made by the inboard section of the left flap.
