Best to speak with local authorities. It will depend of the species you chose.
Usually timber species are managed for wood production and harvesting wood should not be a problem (main purpose of the plantation).
However, in many places, if you want to develop an agroforestry/forestry plantation you have to have certain plan and permits (also needed to reclassify your land-use if you need to apply for financial support). Some species may not be allowed to plant (e.g. classified as invasive) and others may have specific legislation of conservation value.
Choose a list of species, go and check with local authorities if they have special legislation.
But no one can guarantee what happens in future legislation ... :)
One thing I have observed over the years is that many farmers, when establishing an agroforestry system, planning to harvest the trees, they change their perception of value of trees. Many farmers start seeing trees as part of the agricultural land, and then their value on the landscape become more interesting than the money/profitability you can get by removing them... In the end agroforestry gets embodied in the farmer and becomes hard to imagine the farmland without trees...
