Suggestions for Pre Hill Planting
Logging Trails can be difficult, but if they turn out they are great (no lets make that fantastic) for hunting.
The big issues are shade and pH which was mentioned before in this thread. But if the clearings were done in a mature forest then there can be other soil nutrients that may be both deficient and excessive.
I would recommend a soil test( usually the best 20.00 bucks you will spend), not just the pH test(which is a little cheaper).
If you consider your time to finish cleaning up the site, the seed costs, the weed control every two to three weeks for the summer (if you do annuals for a fall attraction type plan), lime(likely needed) and the correct fertilzer(if you even need it), the least cost is the soil test and it can pay big dividends.
I have had friends tried three years to get a good clover stand only to find out they should have made some soil ammendments before starting. Would have saved them a lot of sad faces and hard work.
