Greenways Conservation area is a 124 acre conservation and recreation area located on the Sudbury River in the town of Wayland. SVT owns 63 acres of this area. The site is a mix of wetlands, wet meadows, upland fields, mixed hardwood forest and white pine forest.Management area description:
The management area is a 7 acre field of sandy loam soils with an underlying high (18”-3’) water table which provides for wetland pockets amidst an upland matrix of grasses and fobs. Spotted with small depressions and rimmed by drainage ditches, it contains upland and wet meadow species. The dominant species were a mix of forage grasses, goldenrods, and ferns. The site also included field/forest edge border with white pine/mixed oak forest.
Acres in the management area: 7 Listed on EDDMaps? No
Habitat type: Field/forest edge, Fields, Upland/wetland edge, Wet meadow
Was this Early Detection Rapid Response (EDRR)? NoInitial Overall Invasive Distribution Description:
The field was densely bordered by glossy buckthorn and multiflora rose. There were several large patches and scattered glossy buckthorn throughout the field, and there were also some patches of purple loosestrife, especially in the wetter, northeastern corner of the field. On a site walkthrough, a hybrid of multiflora rose and a cultivar were discovered scattered through the field, and a 30’by 30’patch of reed canary grass was discovered.
Initial Overall Percent Cover of Invasives: 51 - 75%
The main goal of this project was to improve and maintain breeding habitat for birds, butterflies, and other insects that utilize field and forest edges and increase native flora and pollinator diversity.
Approximate project start date: September 1, 2005
Years this project has been ongoing:Project summary:
Mechanical clearing and mowing was done on the field which was followed up by four years of herbicide treatment and native planting projects.
Control method: Chemical, Manual
Disposal method: Brush Pile, Left on siteDetailed project timeline:
Fall 2005- east half of field mowed and small section of edge invasives were cleared; mowed field and cleared edge of multiflora rose and buckthorn
Summer 2007- hired Northern Tree Inc. to clear perimeter of field ; enlarged field to 8 acres
April 2012- site assessment
• Reed canary grass- mowing
• Loosestrife- Galerucella beetles are best, but not enough loosestrife, so cut tops
• Glossy buckthorn and multiflora rose- cut and herbicide for 3 years
June 2012- mow field with tractor and brush hog- height at 8 inches
Summer 2012- butterfly and odonate survey-> NOT COMPLETED due to poor habitat conditions
Spring/Summer 2012- botanical inventory
Aug/Sept 2012- selective herbiciding
• Backpack sprayers used to selectively treat glossy buckthorn and multiflora rose regrowth
• Used 3% active ingredient solution of glyphosate herbicide formulated for wetlands with dye mixed in to track progress
• In unmowed areas, volunteers and certified applicators cut and dabbed buckthorn with herbicide 25% concentration of Rodeo
• Reed canary grass was basically eliminated by mowing
As of 2016:
Conducted three years of herbicide treatment, with a reduction in extent of invasive plants by about 85%
Half of field was treated year one, other half year 2, year three: spot treatment over 70% of field
2015- Introduction of native plants, prepared two30’x 30’plots and planted 1,650 plants between the two
• Laid down cardboard on plots to try to kill sensitive fern and other plants, but it did not work; deer fences were installed around new plantings
• Sensitive fern roots were persistent: for one plot, we planted amidst the roots; the second plot was rototilled which made planting much easier and greatly reduced the need for weeding.
• Despite drought conditions, we had about an 85% survival rate for the new plants
• Contractor hired for one day to selectively treat buckthorn regrowth in field
• 2 volunteer workdays to remove buckthorn manually from forest bordering field
• Planted 400 native plants in one 20 x 25 ft plot with solarization method prior to planting and 200 plants in ten 4x4 ft plots. In the smaller plots, we mowed the vegtation and then rototilled in April.
o Planting in mid-June. In spite of drought, plant survival was excellent (over 85%).
SVT has a list of native plants that we used for anyone who would like to see that.

Final acres in management: 8
Open to the public: Yes
Able to Provide Tours: Yes
Current Overall Percent Cover of Invasives: 0 - 5%Comments / Takeaways
Control of invasives was incredibly resource intensive. In addition to mechanical clearing with large machinary around field edges, 8 days herbicide treatment were conducted over a four-year period. Although reduced by ~90%, future treatments will still probably be necessary
The process was very expensive, so don't do it unless you think your habitat is REALLY worth it. We expect that we will need to do periodic spot treatments indefinitely because of abundant local seed source of the invasive plants.
For native plantings, recommend rototilling plots or using cardboard/mulch for a full year prior to planting. Solarization was also a successful method of preparing a plot.
