Observation Narrative	The plot is located within a younger green ash stand that contains a fair amount of standing dead material. A high frequency of young green ash saplings and seedlings occurs within and around the plot. Potential regeneration for green ash is high in this area. More old, decadent green ash to the east of the plot which is closer to the Little Missouri River.
