An Urban Waters Update

As we shared in September, NeighborSpace was awarded a $60,000 grant from the National Fish and Wildlife Foundation through its Five Star and Urban Waters program for a project that blends hands-on restoration with public educational opportunities and a community science program and that will run through February 2026.* The ultimate goal is to restore and sustain healthy habitat at the three NeighborSpace sites that serve as riparian forest buffers: Levickas Woods (Catonsville), Tollgate Wyndham Preserve (Owings Mills) and Volz Neighborhood Park (Middle River).

The first step is to thoroughly get to know these sites, on a number of levels. 

  • Canopy and understory health: Do we have a healthy population of mature canopy trees of different species and at various stages in their life cycle? Are there areas where trees are threatened by vines? Is the next generation of saplings robust or do we need to supplement the understory with younger trees or different species? If species diversity is adequate, what native tree species are present and thriving and might we want to plant more of in similar conditions?

  • Groundcover health: What is the ratio of native to non-native shrubs, perennials and groundcovers? What native plant species are present? How can we help those species thrive and spread? Do we want to add other native species to the landscape? What invasive species are present and what threat do they pose? We will likely divide each site into different areas, tiered by their level of infestation, the prevalent species of invasive plant and the speed at which it is known to spread. In general, when removing invasives, we prioritize areas with the lowest density of infestation to prevent the spread and then gradually move inward, with the ultimate goal of replacing the invasive population with a healthy native ecosystem.

  • Wildlife: Which animals already call these sites home? How can we improve their habitat? Are certain animal species absent that we would expect to see, and what habitat essentials might be missing from the site?

  • Stream health: Is the stream connected to its floodplain or are the banks severely eroded? What do simple measurements tell us about the water quality and are there actions we can take to improve it?

The spaces between layers of gravel, small stones and boulders provide crucial habitat for small aquatic bugs such as caddisflies.

These observations will inform which restoration actions we take in the next phase of the project. For example, Yellow Warblers prefer to nest in dense shrubs, so if we observe Setophaga petechia at one of our sites, we might plant alder or willow shrubs along the stream, and maybe some wax myrtle to supplement their summer diet. Or if stream banks are eroded and suitable tree species are present, such as willows or red twig dogwood, we might consider live staking as an effort to stabilize the banks. If we uncover healthy sedges while removing invasives, for example, the best approach might be to keep the area clear to allow them to spread or we might choose to fill in the cleared soil with additional quarts of Carex pensylvanica.

All this to say, we want to understand the existing ecosystem and establish a baseline to measure future progress against. Restoration activities should strengthen the existing ecosystem by allowing species that are already doing well to flourish and by supporting struggling species by removing threats and bringing in missing elements. By continuing to make observations on a regular basis, we’ll be able to track the impact of our restoration efforts, observe which techniques are successful and adjust our approach where needed.

Over the winter, NeighborSpace staff has consulted a variety of resources and a number of experts and we are working to finalize a new assessment protocol to collect, document and track data on trees, other plant growth, wildlife, stream health and possibly soil health.

This is where we could use your help! If you would like to assist in surveying NeighborSpace sites, please let us know. If you are a plant ID expert, a birder, an amateur entomologist or herpetologist, and you are willing to donate a few hours to make observations at one or more NeighborSpace parks, we would greatly appreciate it. If you don’t fall in any of those categories but you are an outdoor enthusiast willing to share your time with NeighborSpace, we would welcome your help. Please reach out to me at phyllis@neighborspacebaltimorecounty.org or (443)850-2756 to set up a meeting with a staff member.
