No reason to hold it for a year. He may have misunderstood, or else he may not have much experience with timber sales.
See the presentation pdf at this link. Although, it may make it more confusing since there is a lot of info there. Your tax preparer would only need to use form 8949 and Sch D for reporting.

I think a lot of people get thrown off with the ordinary income vs. capital gain. If it is a short term capital gain (less than a year) it is taxed at ordinary income rates but it is still a capital gain income. When held more than one year it is taxed at capital gain rates. In both cases the gross proceeds are reduced by your basis in the property.
See a copy of Schedule D here. Top half is short term and bottom half is long term.

I am also very busy until April 15, but I am taking a partial break today after a hectic past month. So if you catch my drift I know a little bit about taxes. I was trying not to think about work for a few hours and look what happened :D
