Annual Tree Planting

There are no new plantings planned for 2018 as the tree field has reached saturation. Watering and nurturing of planted trees continues. The story of our thoughtful battle with invasive knotweed is promoted by the Arbor Day Foundation.

Friends of The Moshassuck has been planting trees at Collyer Field in Providence for over 18 years. The site is a field of invasive alien Japanese knotweed, and our planting is an effort to eliminate the invasive alien weed by growing big and tall trees to shade it out. Preliminary results suggest that the effort is starting to bear fruit, and under the earliest plantings (and biggest trees) the knotweed is showing the effects of shading. We believe this is a community-friendly, totally non-toxic, way to deal with one of the most invasive plants in Southern New England and would be happy to help any local organizations seeking to restore areas damaged by knotweed. We are iterating on a map and database of our cumulative tree plantings.

Friends of the Moshassuck thanks the RI Rivers Council for their financial support of this project.

The 2016 tree planting was captured through video:

After a winter that was significantly warmer and drier, we had a late season snowstorm that put our April 9th tree planting date in jeopardy. Thankfully, rains helped clear the snow 36 hours before our planting and the weather was sunny and warm for the day. On the docket were four new contributions to the emerging forest: one Sun Valley Red Maple, one Dogwood, one Forum Black Gum, and one Swamp White Oak. Welcome to the family, friends.
There are a lot of roots and rocks to dig through as we are getting closer to the gravel field on which parking is allowed.

This year's trees each suggested a different sized hole: each a different width and a different depth.

Each year we get a greater satisfaction when looking back at all the previous years' plantings. All but five have survived from their planting date.

The first trees we planted are effective at shading out knotweed as seen by this evidence below. Image A is a photo of the whole Collyer Field tree planting area on June 8, 2016. Image B shows the knotweed exposed to full sunlight is taller than Greg and Douglas (who helps us identify trees and suggest forest health). Image B shows the knotweed among the first trees planted in 1999 and 2000. Greg is significantly taller than the knotweed reach.
Thanks to the Green Team volunteers, some knotweed is removed at the height of summer each year.
