The Terms and Conditions of the REPS 4 scheme stated that where the eligible area for the Scheme was decreased, the annual payment would be adjusted at the commencement of the next full year. The re-imbursement of aid already paid was not required in respect of lands afforested under Council Regulation (EC) No. 1698/2005. However, where land was afforested during a REPS recording year, a proportionate reimbursement would apply for the part of the REPS year that had not been completed.
The EU regulatory provisions for the subsequent agri-environment, climate measure (GLAS) which is an action rather than area-based scheme did not provide for such reimbursement options. They also required the clawback of any monies paid under the scheme on land which was subsequently afforested at some later point in the scheme.
