Analysis

The plt rprtd he lost control of the acft during takeoff on a soft/rough strip covered with low bushes. Subsequently, the acft went off the rwy, ran into alders, & nosed over. The plt believed the acdnt may have been avoided, if the strip had been mowed so that its rough areas would have been seen.
