As a grower, they are your trees and you have leased the land, at worst, you will need to go and cut down your own trees, and sell them.

Chances are a new manager will be found who will manage and sell your trees for a fee. You will need to sign a document accepting the new manager. Expect the fees to chomp into your investment.

If your trees have been cut down and sold already, and if you are yet to receive the cheque, that maybe goodbye investment.
Good luck 1998 plantation holders, hope you get more of the harvesting cheque, and the money has not been squandered. If the company has any morals your money should be safe in a trust fund.
If they are greedy, they could have kept the proceeds.

If your tree plantation is only a few years old getting a manager maybe more difficult. You may need to pay the manager, a yearly fee, or relenquish or sell your investment.

Your trees are worth something, but probably around 8% of the total invested, multiplied by the number of years you have had the project. Expect a yearly management fee around 3% of the total amount invested per year.
If you get to year 10, expect management to take 20% to harvest and transport.
You may also need to pay money for your lease to the new manager which may chew up another 2-3% of your investment per year.
If your trees are nearly ready for harvest it will be worth paying the fees. If you are at year 1, its a lot of money to throw into the money pit, to save your investment.
