Arboretum Area D

The Acton Arboretum has an area adjacent to the parking lot which has long been ignored. An attempt to clear invasive plants from this area was started in 2022.

Area 1 - Adjacent to Parking

This area adjacent to the parking lot, bounded by a boulder covered drop-off, was infested with Asian Bittersweet, growing over the Bush Honeysuckle, as well as Garlic Mustard underneath. Clearing was started in 2022.

Regrowth was cleared in 2023, along with expanding the cleared area somewhat. Permission was obtained from NR and the Friends of the Arboretum to kill (gird) over a dozen small Black Walnut trees in this area, which were crowding out the Eastern Cedars.

Area 2 - Down the Hill

This area starts at the parking lot and continues down the hill (without a boulder covered drop-off, although it wraps around the bottom of one!) It is infested with Asian Bittersweet, growing over the Bush Honeysuckle and Multiflora Rose.

There are paths and clearing throughout this area -- in particular, one down to Area 3 --- which are gradually being expanded. Clearing started in 2022, and continued in 2023.

Area 3 - The Clearing over the Brook

This area is clearing on the west side of a bridge over the stream feeding through this part of the Arboretum. It was infested with Asian Bittersweet, Bush Honeysuckle and Multiflora Rose.

Clearing started in 2021 (although there was certainly some clearing before that). The last clearing in 2023 also cleared the stream banks for 40 ft upstream/downstream of the bridge.

Area 4 - The Redbud Glade

This area is infested with Asian Bittersweet, growing over the Bush Honeysuckle and Multiflora Rose (surprise!). It is adjacent to a main (Yellow) Arboretum trail, yet presents an awful view of nature. The exception is in the spring, when the Eastern Redbud trees growing throughout flower.

It has been worked off and on for years. The main effort these days is to kill the Asian Bittersweet (to prevent it from killing the Redbud saplings.)

Area 5 - Garlic Mustard

This area, while infested with Asian Bittersweet and Bush Honeysuckle, is also listed by Jim Snyder-Grant as having a Garlic Mustard infestation.

Area 6 - No Man's Land

This area is infested with Asian Bittersweet, growing over the Bush Honeysuckle and Multiflora Rose. In 2022, paths were cut allowing access to cut the Asian Bittersweet off of trees in the area.

In 2023, these paths were expanded to allow access to all trees in the areas.

Area 7 - MF Rose and Rock Piles

This area is infested with Bush Honeysuckle and Multiflora Rose. In 2024, a path was cut from the yellow trail to allow access to cut the Asian Bittersweet off of trees in the area.

The back area (farthest from the trail), kinda marked as wetlands on the map but not really, is a nice grassy glade under the pine trees. Glossy Buckthorn and Multiflora Rose are trying to get a foothold here (in 2024).
