The most desirable aspect of broadcast seeding is that there is no row effect such as that which results from drill seeding. This lends a more natural appearance to the planting. However, broadcast seeding may not desirable if the weather is hot and dry and/or the soil moisture is content is low. It is essential that steps be taken to ensure good seed to soil contact when broadcast seeding is used. A) Site Preparation - The site should be prepared by loosening topsoil to a minimum depth of 3 inches. It is critical that the seed bed be loosened to a point that there are spaces for seed to filter into cracks etc., otherwise it may end up on the surface and wash away with the first heavy rain. B) Seed Installation - Seed should be installed by broadcasting it evenly over the entire site. Several types and sizes of broadcast seeders are available for use, ranging from fertilizer-type spreaders to power spreaders mounted on all terrain vehicles. Seed should be mixed thoroughly prior to seeding and should be mixed occasionally in the spreader to prevent separation and settling. C) Seeding Rates - Rates are specified in the mixture tabulation for the specified mix. D) Harrowing -The site should be harrowed or raked following seeding. E) Packing -The site should be packed using a culti-packer or equivalent following harrowing. F) Mulch - The site should be mulched and disc-anchored following packing using one of the following types of mulch (as per plans or special provisions): • MCIA certified weed free mulch at a rate of 2.0 tons per acre. • Prairie hay/mulch (Mn/DOT Type 7 or 8) at a rate of 2.0 tons per acre. • Mn/DOT Type 1 (clean straw) mulch at a rate of 2.0 tons per acre. G) Straw Blanket — Straw blanket containing double netting (Straw 2S) will be used in areas shown on plans and installed per manufacturer specifications.

Check the additional resources and herbicides table for more information. ORONO COPY What you can do to control buckthorn! Controlling seedlings or small buckthorn plants X Removing small buckthorn with hand tools For individual plants If less than 3/8 inch in diameter, remove by hand. Small seedlings can be pulled and will not re-sprout. If greater than 3/8 inch, use a hand tool that pulls the shrub out, such as a "Weed Wrench" or "Root Talon". The "Weed Wrench" comes in four different sizes and will remove buckthorn stems up to 2.5 inches in diameter. Removing by hand is easier if the soil is moist. Before you pull or dig buckthorn out of your soil, Contact Gopher State One Call (1- 800-252-1166) to ensure there are no buried utilities in the area. If pulling individual plants is impractical Spray foliage of short buckthorn or seedlings with a herbicide. Glyphosate (one brand name is Roundup) will kill all actively Removing small buckthorn growing vegetation on which it is sprayed. Triclopyr will kill with hand tools. broadleaf plants and will not harm grasses when applied properly. Controlling large buckthorn � Buckthorn plants that are two inches in diameter or larger, are best controlled by cutting the stem at the soil surface and then cover or treat the stump to prevent re-sprouting. This can be effectively done with hand tools (for a few plants), chain saws or brush cutters. If only cutting a few stumps they can be covered with a tin can or black plastic to prevent re-sprouting. Otherwise, stumps should be treated immediately after cutting (within 2 hours) with a herbicide containing Triclopyr(such as Ortho Brush -B-Gon or Garlon 3A or 4) or Glyphosate (Roundup) to prevent re-sprouting. The best time to cut and chemically treat the stumps is in late summer and throughout the fall. Avoid treating buckthorn in May and June when the tree is putting out leaves as the herbicide will be less effective at this time then during the rest of the year. Herbicides can be applied to cut stumps with a paint-brush, wick applicator or a low volume sprayer. When using water-soluble herbicide products like Ortho Brush-B-Gon, Garlon 3A, or any of the Glyphosate products, treat only the cut surface. When using oil-based products like Garlon 4 or Pathfinder II, treat the cut surface and the remaining bark to the ground line. In cases where more than a few plants are treated, add an indicator dye (available where pesticides are sold) to the herbicide to mark cut stumps you have sprayed.

When - - - --�� buckthorn is cut, the stumps are easily covered and X Hand tools forcutting buckthorn lost under cut brush. Chemical treatment in the winter: Buckthorn can be treated throughout the fall and winter. Follow herbicide label instructions regarding temperatures at which the herbicide can be applied. Water- soluble herbicides like gyphosate (Roundup, Rodeo, etc.) or triclopyr amine (Garlon 3A, Brush-B-Gone, etc.) can be applied to cut stumps when the temperature is above freezing (32 deg. F). Oil-based Hand tools for cutting buckthorn. products of triclopyr ester (Garlon 4, Pathfnder II) can be applied when the temperature is below freezing (below 32 deg. F). For basal stem treatment, a method that applies chemical through the bark, low volume spray applications can be made with Garlon 4 and similar oil-based products. This application method uses Triclopyr ester miXed with an oil diluent (i.e. Bark Oil Blue, kerosene or diesel oil) applied directly to the bark of buckthorn from the root collar up about 12-18 inches. This treatment works best on stems less than 2-3 inches in diameter. An ultra low volume spray wand should be used to minimize herbicide use and reduce the potential for non-target injury. Buckthorn treated in this fashion can be left standing or cut at a later date. Note: Buckthorn seeds in the soil can remain viable for up to five years. Follow-up control of seedlings — - - - that emerge after initial control efforts is important X Applying chemicals to cut buckthorn on all sites. With no follow-up control, buckthorn will come back. Fire offers a long-term management option in grassland or savanna cover-types. Burning will need to be done every two to three years. If burning is not an option, a follow up treatment of the seedlings (pulling or spraying) is needed. After buckthorn control, many sites may require replanting of desirable tree, shrub, and herbaceous species.

The landowner needs to provide a proposed seed mix and pounds per acre it will be installed. Prairie Moon Nursery and Prairie Restoration Nursery are good sources for native seed mixes for upland areas. For this area of Orono I would recommend a mesic prairie mix. It appears from the write-up that he is proposing not to excavate and remove the turf but till the top three inches instead. If this is the case the grass should first be sprayed and killed with a water-soluble herbicide like gyphosate (Roundup, Rodeo, etc.). If he is completing removing the turf grass including roots by excavation spraying with a herbicide will not be necessary. He needs to verify in the write-up what approach he is going to use. I would recommend that he not limit himself to hand pulling buckthorn only. Some of the buckthorn is larger and he may want to follow the approach for large buckthorn from the DNR so he is not limited(see attached). If he wants to use the attached approach he should reference it and provide it as an attachment with his submittal.
