%X The study presents a new approach for aggregating stands for harvest in  strategic forest planning. In fragmented landscapes this could benefit  nature conservation as well as reduce costs. The approach is built on  the idea of minimizing the outside perimeter of contiguous harvest  areas. The formulation allows for the use of exact solution methods such  as mixed integer programming. The method was tested in a landscape  consisting of 2821 stands. The application showed that large and compact  harvest areas were created with limited sacrifice of financial value.  The mixed integer programs were in most cases solved within a couple of  hours. The method needs to be tested on different landscapes with  different degrees of fragmentation. It is also necessary to evaluate the  long term consequences of the large clear cuts that appear to be a  consequence of this problem formulation.
