Here is a link to the stats for the 2010 General Sign-up. It includes total new acres enrolled by state and each states average rental rate (per acre).

South Dakota's average rental rate is $50. Probably a little less than that West River and a little more than that East River.
Not good. For all the rhetoric from the USDA saying they were going to increase rental rates it didn't really happen. That is why SD ultimately lost acreage when you factor in expiring acres vs. newly enrolled acres. Couple that with the likely scenario that most of the new enrollment acres are West River and outside the good upland base I see SD pheasant numbers declining in the future.
Areas with lower cash rental rates like parts of KS, NE & CO did pretty well in the last sign-up.
As Wirehairs correctly stated the 2012 Farm Bill will be critical. I'd put membership in PF, DU & TRCP at the top of the list. These three organizations do a great job working together in Washington and off setting anti-conservation lobby influences from big ag.
Secondly I'd be prepared to start emailing your representatives after the first of the year and pressuring them to influence the USDA on two points.
1. Approving a 2011 general sign-up to replace expiring acres.
2. Increasing rental rates and making them more competative with other options.
It's just my opinion but long term I'd also reference putting Conservation Program support ahead of the renewable energy boondoggle in the 2012 Farm Bill. The big winners in Wind & Ethanol are GE, Vestas, Archer Daniels Midland, Carghill etc. With conservation programs the money goes directly to the property owners and the soil conservation, water quality and bio-diversity benefits accrue for all taxpayers.
