Transforming the Back Swamp
by Mira Grieser
For many years, most of us have hurried past the area behind the HMC parking lot on the way to or from church, barely glancing over to see the mass of vines growing out of areas of standing—or sometimes rushing—water. With a closer look, English ivy vines were crawling up tree trunks, layers of euonymus vines covered the ground, and bush honeysuckle had spread rampantly. The vines had already brought down some of the medium trees, and these invasive plants were providing very little benefit to the ecosystem.
But thanks to significant hard work from a lot of HMC attendees, this parcel of urban tree canopy has started an incredible transformation towards a healthy and thriving ecosystem that supports all levels of plant, insect, and bird life here in Hyattsville. This work aligns well with what we and many communities of faith see as a call to be stewards of the environment and care for creation.
This work starts with native plants and trees, that have evolved with native wildlife to create an intricate ecosystem. Attracting pollinators is a key function of plants, which then can support all types of life.
While we have viewed this area’s tendency for standing water as a negative, we see here an important function—to be able to absorb run-off from surrounding areas—and keep the water on the property rather than running into the sewers, washing topsoil and trash with it into the rivers. Many native plants have deep root systems, which can help manage run-off. In contrast, the invasive vines and bush honeysuckle have shallow roots.
And the timing of this project is great because many urban municipalities are looking at ways to preserve and enhance their tree canopy, recognizing that trees can mitigate some of the effects of climate change. There have been studies that have found as much as a 25 degree difference in air temperature under a tree compared with air temperatures over a blacktop.
With this background, here is what we all have accomplished together on this project so far:
- We held 3 workdays focusing on invasive plant removal. 15 people can make a lot of progress in a couple of hours on pulling out vines and digging out roots!
- We rented a wood chipper and spent hours turning 2 massive piles of branches into beneficial mulch.
- We filled 60+ bins with vines and other invasives, which were then picked up by the City of Hyattsville and transported to the PG county organic composting location.
- We cleared some dead and dying medium sized trees, thanks to the professional efforts and chainsaw of forester, Alex Navarri.
- We created a wood chip path that will encourage wandering through the woods, while keeping feet dry.
- The City of Hyattsville planted 20 trees! We chose a variety of species, such as bald cypress and black willow, which will develop extensive root systems to better absorb water and support an incredible variety of insect and bird species. The trees were all FREE to HMC supported through funds made available by the American Rescue Plan Act to preserve the urban tree canopy. We have made valuable connections with administrators of the City of Hyattsville who are very supportive of these efforts! Note: if you are a resident of Hyattsville, you are eligible for free trees!
- We met with folks from Chesapeake Natives and other local native plant advisors for ideas on areas of focus. In exchange for the use of our building for a meeting earlier this year, Chesapeake Natives will be giving us plants: Shrubby St. Johns wort, cardinal flower, goldenrod and asters.
- We have started adding other natives as they are available. Many folks are happy to share starts. So far we have the following, all of which support pollinators including native bees, flies, butterflies and moths and bloom at different times.
- Cut-leaf coneflower (sochan)- the early spring leaves are edible (like spinach or kale).
- Golden ragwort
- Black-eyed Susans (the Maryland State flower)
Looking ahead, the challenge will be to maintain the areas that we have cleared, especially as the vines start growing in the warmer weather. The focus will be on keeping the trees cleared and watered especially this first summer. More information will be coming on how to help with these efforts.
In this time of feeling overwhelmed by climate change, this is one area that we do have control of, and can make a difference. And it has been inspiring to discover that we are joining the efforts of other faith communities, municipalities, and individuals, hopeful that together, we can make a bigger change.
