If a"closed"canopy of weed cover develops, it should be mowed to aid in the <br /> growth of the prairie seedlings by reducing competition. Mowing may also be necessary if the <br /> weeds are about to set seed. Optimum cutting height, depending on the wildflower species <br /> present, is typically 4 to 6 inches. Mowing done by PRI will be billed separately unless they axe <br /> included as part of the installation contract. <br /> • In years following the first growing season, management services could include site monitoring, <br /> burning, mowing, spot spraying, or hand weeding. These services should be contracted <br /> separately from the installation contract. Please note that management services are typically <br /> billed on a time and materials basis (a breakdown of cost ingredients would be available prior to <br /> contract acceptance). <br /> Costs: <br /> Prairie grass and wildflower buffer seeding. <br /> Site preparation, seed and seeding as specified ............$2000.00 <br /> First year maintenance (2008).................................................... 500.00 <br /> Total.................................................................$2500.00 <br /> Second year maintenance...........................................................$500.00 <br /> Third year maintenance..............................................................$500.00 <br />� <br />
