Security Interests in Marketable Timber

[John Jessie]

I am looking at land that has a fairly decent stand of marketable timber on it. The land has decent a location (i.e., it's not in the middle of "no-where"), but it is on the side of a hill, knob. However, it does have a nice pond on it that may provide for an attractive site for some development once the land is cleared off.

My question is in regard to the bank note needed to buy the land and the bank's interest in the timber. Let's say, for instance, I get the land (50 acres) for $100k ($2k/acre). A portion of the timber, after it's harvested and sold, brings $60,000. In KY, we typically do a 50/50 split with landowner and logger. Therefore, I would realize $30,000 in the transaction. Would a bank require a security interest in the marketable timber, requiring me to give them the $30,000, due to the harvest of the timber and possible diminish in value of the land? 

I have talked with @Jay Hinrichs about this briefly, but I would like to see if anyone has any perspectives from the angle of a bank/lender. 

Thanks in advance.
