The black dots and the black curve show actual harvest for the same periods.
AHM started in 1995. Notice that the waterfowl managers prior to 1995, were very effective at using season and limits to manage harvest rates in response to changes in waterfowl populations.
But, once AHM started, again in 1995, as the flat section highlighted by the red circle shows, season and limits haven't changed once. This "Adaptive" method has refused to adjust to lower duck numbers as indicated by the drop in harvest rates since 2000.
It doesn't take an expert in trend analysis to understand that harvest rates (black line) are going to continue to drop unless someone grows enough backbone to lower the opportunity (blue line).
I'm curious, RH, how does this graph look for the other 3 flyways?
Listen to your elders. Not because they are always right but because they have more experiences of being wrong.
