You really need to check the SC rules/laws. The county extension office should be able to help you and very likely the information is on the web.
For what it is worth most of our land is under a timber valuation. I had to show that we had or planned to timber the property, produce a map showing timber types and location, roads, trails, etc. Not real hard to do since we had timbered the property and had already made money.

I also had to create a timber management plan.
The state Forestry department will do this but there is a wait time for them to do the work. I talked the local Forester and was not impressed with his attitude so I did my own d....ed plan.

The NEW state Forester seems to have his act and attitude right but it would still take time for them to do the plan so you have to start well before the valuation deadlines. None of the above is hard, information on what to do was on the web and available from the extension office.
The extension office had a meeting over timber, Ag, and wildlife land valuations late last year. The state is going to be reviewing some of the older valuations to verify they are still valid. The first part of the meeting was a bit tense since we did not know what the state/county was up too.

:laughing: We thought maybe the rules were getting changed and we were going to get the shaft.
Right after we bought our land it was time for the county to evaluate property values. At the time the county was doing evaluations every seven years. Our property values went up FIVE time, 500%. Without a timber valuation we would have had to quite a bit of the land which is ironic since many people in the county, especially the county government are against development. Their property tax would have forced us to sell and given we are in a prime location they land would have sprouted houses. Just what the county does not want. :mur: :confused3:
But we were able to get a timber valuation and all is good. :thumbsup: :dance1:
Get thee to the county office or website.
