Begin grove educational project. Phase II: 4- Develop eastern trails with markers. Construct primary (western) council ring. Phase III: Construct secondary. (eastern) council ring. Construct eastern wetland boardwalk and viewing platform. Management: The trails will be maintained by girl scout troops. Assistance may be provided by Smith Vocational Technical High School Forestry Department (contact: John Szafransky: 413-587-1436, szafrans@massed.net), Hampshire County Educational Collaborative, and Northampton Planning Department (contact: Cynthia Williams: 413-587-1263)• Trail maintenance. . Grove educational project. Invasive exotic management (see below). + Headquarters grounds: Phase I: New front sign. Begin eastern meadow educational project. Begin grove educational project. Remove invasive exotic ornamentals. Phase II: Construct septic mound at cottage. -Plant shrubs on septic mound. Construct bio-swale. Phase III: Demolish and construct new driveway (reusing foundation material & reusing fill and topsoil). Demolish ramp and construct deck. Construct walkways, stairs, and terraced planting beds. Begin planting beds educational project. Plant hazel thicket and birch/aspen groves. Plant low-growing meadow. Manggemenbe ❖ Meadow editing educational project and planting bed editing educational project: The meadow will be allowed to grow from its current form of mowed grass. Wildflowers will be encouraged and planted in from the planting beds at the cottage by girl scouts. The meadow will be mowed at the frequency of once to twice a year at the discretion of the maintenance staff. The mowing is the mechanism for removing woody growth. The scouts should participate in this ecological exercise by planting wildflower seeds in the beds and transplanting into the meadow, and removing exotic plants as they appear. ❖ Grove educational project: The students will collect nuts, acorns and seeds from the Back V and propagate these at home. The seedlings will be planted in the grove and allowed to grow over time (see seed list). Septic mound shrub planting project: The mound is seeded initially with turfgrass to prevent erosion. Shrubs are planted on an annual basis starting with the largest slope areas to reduce mowing hazard. No shrubs should be planted on the level area, which is to be maintained as .a turf pathway to the cottage and top of the mound. ❖ Invasive exotic management: -Japanese knotweed (western wetland) : should be cut with a weed-whacker monthly or bimonthly. Efforts may be aided or directed by Hampshire County Educational Collaborative. The evergreen hedge will provide shade on the invaded area. The hedge will be allowed to grow without trimming. If trees appear sick or damaged from root burial, they should be replaced with evergreens as soon as possible. -Invasive exotic ornamentals (Norway maples & burning bush): should be physically removed and could be used for woodchips. Maple stumps should be ground out. ❖ Bio-swale monitoring: The Swale should be periodically monitored for the invasion of exotic species. Any invasives should be spot treated with herbicide to ensure root death, and removed as soon as possible. Once annually, the Swale should be inspected for siltation. Excessive sediment should be removed and used as sand/gravel for the walkways and parking lot during the winter. ❖ Turf mowing: The mowing area will gradually be reduced as the ferns, meadow, and low-growing meadow are allowed to grow and spread. The only areas requiring continual mowing includes the field between the buildings, the pathways from the headquarters main entry to the basement and to the trails, the border alongside route 9 and on top of the septic mound. Low-growing meadow: The low-growing meadow will be established and . maintained through mowing regimes and planting low growing plants. Pine needles will be allowed to collect under the two large white pines and will start before planting is done. Planting will be by seed except for Canada mayflower, wintergreen, and wild strawberry. These three species will only be planted in the pine needle beds and will not be subject to mowing. Pine seedlings will be allowed to sprout in the needle beds., Outside the needle beds mowing will be done 4-5 times per year. As in the tall meadow to the east, the Girl Scouts should remove by hand exotic species that become established in this area. Ferns: Initially mowing will be no closer than 1-foot outside the fern area. ~As the ferns start to establish and spread, the mown area will be decreased with the ferns eventually covering the entire space between the bio-swale and the headquarters. .Bach 40 Plana List: r'nmmnn nnmP Taxonomic name Key JBio-swale detention pond: Cattail broadleaf T ha latifolia Cattail narrowleaf T ha an ustifolia Soft stem bullrush Sca us validus Sweet flag Acorus calamus Burr reed S ar anium americanum New lawn areas: Sun Shade Mix Various west side: Ostrich fern Matteucia struthio teris Bracken fern Pteridium a uilinum New York fern Thelypteris noveboreancensis Christmas fern Pol stichum acrostichoides Sensitive fern Onoclea sensibilis HQ foundation High-bush Blueberry Vaccinium co bosum VC Winterber Ilex verticilata IV Trailhead & field enclosure: Paper birch Betula a °fera BP Gray birch Betula o ulifolia BO Quakin aspen Po ulus tremuloides PT Big-toothed aspen Po ulus randidentata PG Meadow wiidflow'ers: Butterfly Milkweed Ascle ias tuberosa New England Aster Aster novae-an liae Wild geranium Geranium maculatum Wild strawberry Fra aria vir iniana Cardinal Flower Lobelia cardinalis Tall Meadow Rue Thalictrum ubescens Turk's Ca Lily Lilium su erbum Sneezeweed Helenium autumnale Great Lobelia Lobelia si hilitica Golden Alexanders Zizia aurea Cinquefoil Potentilla novve ica Little Bluestem Schizach rium sco arium Low-growing meadow Canada Mayflower Maiathemum canadense Wild Strawberry Fra aria vir iniana Wintergreen Gaultheria rocumbens Canada Violet Viola candensis Down Yellow Violet Viola ubescens Wool Blue Violet Viola sororia Partridge Pea Chamaecristae fasciculata Barren Strawberry Waldstenia fra aroides Trout Lily E honium americanum Potentilla Potentilla canadensis Wild Lettuce Lactuca canadensis Pennsylvania Sedge Carex enns lvanica Little Bluestem Schizach rium sco arium Septic mound: Low-bush Blueberry Vaccinium an ustifolium VA Mountainlaurel Kalmia latifolia KL Roseshell Azalea Rhododendron roseum RR Black Chokeberry Aronia melanoca a AM South of cottage: High-bush Blueber Vaccinium co bosum VC Winterber Ilex verticilata IV Witch Hazel Hamamelis vir iniana HV Cottage planting beds Butterfly Milkweed Ascle ias tuberosa New England Aster Aster novae-an liae Wild Geranium Geranium maculatum Turk's Ca Lily Lilium su erbum Golden Alexanders Zizia aurea.

Trailhead is clearly visible and easy to find. Erosion is minimized. Disturbance to habitats is minimized. Trails provide programming opportunities: Interpretive signs are provided. Two council rings are sited. Trails visit different habitats and plant communities. Trails visit areas disturbed by human activity. Council Ring: Comfortable seating for thirty-five people. One council ring is within 1,500' of headquarters. Council ring does not affect sensitive areas. Minimal site alteration is required for council ring installation. Minimal tree removal is required for council ring installation. Benches are 1 foot deep. Benches are 16" above grade. Council ring is oriented on a north/south axis. Drainage: Amount of impervious surfaces is minimized. Parking lot runoff is filtered prior to reaching wetland. Flooding at basement entrance is solved. Erosion along building is solved. Parking: Parking accommodates entire staff (16) plus three guests and one handicap accessible space. (19+1H) Amount of impervious surface is minimized. Parking lot runoff is filtered prior to reaching wetland. Service vehicles can pull.through the lot. Vehicles have access to headquarters basement entry. Views of parking areas are screened from Haydenville Rd. Handicap accessible space is within 20 feet of the handicap accessible ramp. Impervious surfaces are at least five feet away from the base of significant vegetation. Foundation materials are reused from original parking lot site to proposed site. Original parking lot surface is recycled as aggregate for proposed parking lot. Subsoil and topsoil excavated from proposed parking lot is used to fill original parking lot. Bio-swale: Soil excavated for swale construction.is used in septic mound construction. Vegetation: Invasive exotic ornamentals are removed. Native vegetation is protected. Vegetation reflects typical. associations for area (<50-mi. radius). Vegetation requires minimal maintenance. Vegetation does not obstruct lines of sight along Haydenville Rd. for vehicles entering and exiting. Vegetation enhances appearance of property. No significant tree roots are severed during construction.
