After looking at the park there is a good amount of buckthorn throughout the park. There are two species of buckthorn present both Glossy and European. The Glossy buckthorn is mainly in the wetter areas while the European buckthorn is mostly in the wooded areas. Both species need to be removed as part of the parks restoration. I arm proposing that the buckthorn be cut this winter over frozen ground allowing for the use of tracked skid steers to assist in the removal process. Since there is a desire to restore the wetland in the middle of the park to a native plant community where fre will be a management tool I am proposing the buckthorn be cut piled and burned on site. The buckthorn should be cut and taken to the future parking lot area and burned in one pile. Smaller buckthorn seedlings and saplings will be cut with a clearing saw and left to break down on site. The buckthorn with steams larger than 1 inch will be treated with herbicide to kill the stump. Along with the buckthorn removal process most of the woody derbies from broken down dead trees will be added to the burn pile to help clean up the site. Any good fire wood material can be saved and piled in the parking lot for the public to have,at no charge. If burning the material is not an option it can be stock piled to be hauled away or chipped and reused for walking trails throughout the park. Hauling and chipping is not something PRI is capable of on a large scale. We would need to find a sub contractor to complete this task. 1 estimate the cutting piling and burning of the buckthorn and other woody debris to cost around$9,750.00 plus tax. The middle of the park is dominated by a reed canary wetland. As part of the long term plan to restore the wetland to a native plant cornmunity the reed canary needs to be killed off. There are many ways to do this; I am recommending the area be sprayed this fall. This is a very effective time of year to kill reed canary. In the 2013 growing season we will be able to determine how much if any native plants are present on the site. This will be a good first step in the restoration process. I estimate the cost of the 2012 fall reed canary spraying to be around$1,500.00. . r. r..:r- '•: s. . � � • Bringing people together with the land ,� � r. ,• . ��I�y�y��, �r`,t��if��;,. ;L I Prairie � Restorations, lnc.

We utilize this trait to our advantagel�by spraying the buckthorn later into the fall after most of the natiVe plants have went dormant for the year. Since buckthorn has spread everywhere there will always be a need to manage the woocis to keep buckthorn out. However after 3-4 years of rnore intense management the woodland can usually be managed for buckthorn at a mweh lower cost. It is ve�hard to come up with an accurate estimate of the buckthorn spraying costs for the next several years. However I est�mate the fall buckthorn spraying in 2013 to cost between$2,500-3,500 plas tax. After the removaf this fall winter and seeing how things look in the spring I will be able to give a much more precise number. ; � To summarize the cost estimates above. i ') 1, 2012 Fall reed canary spraying$1,500.00 � 2. 2012/2013 Fall/Winter buckthorn and light editing of wooded areas$9,750.00 plus tax. �� 3. 2013 Buckthorn fall spraying between$2,500-3,500 plus tax i ;� � c� J in Sykora Land Management Coordinator Prairie Restorations Inc.
