Management Case Studies
Prior to treatment, the wooded areas were very heavily infested with shrub honeysuckles and common buckthorn and a few plants of Japanese barberry. Plants ranged in size from small seedlings/saplings to mature, fruiting plants. Contractors were originally concerned that treatment work on this property might not be feasible or successful due to the heavy level of infestation.
Area Identification: The entire park has been surveyed for invasive plants and the majority of the park has been treated.
Target Invasive Plant Species: The dominant invasive plant species at the park are bush honeysuckles, common buckthorn, autumn olive, garlic mustard, black swallow-wort, European alder, Japanese barberry, Norway maple, winged euonymus, and black locust. The park hosts several other less common and less aggressive invasive plants, and will likely be tackling some of those over time.
Area Identification: The Equinox Highlands Natural Area is 2,276 acres and is owned by The Nature Conservancy. Invasive plant treatment was focused on 312 acres of the SVAC parcel (the parcel was previously owned by the SVAC and purchased by TNC in 2010). On the 312 acres of the SVAC land, invasive plant treatment was concentrated on the lower slopes of the property, between 1100 and 1600 feet in elevation. The areas is wooded, bordered by a meadow and adjacent parking lot on the eastern edge. Several hiking trails weave through the property.
