After scanning the perimeter of North Cove, the search narrowed in on the Phragmites marsh.
Prof. Brian Prendergast saw that the satellite tag on a striped bass he was tracking had detached and was floating near Salter Grove. He contacted FoSG for support in locating the tag so we reached out to members and collaborators.
Brian Prendergast smiles as his detector indicates the satellite tag is nearby.
After recovery, the tag was passed to Scott Bennett, Program Manager of the Striped Bass Initiative who had joined the search from the Marine Biological Laboratory. He will download the data so the striped bass’s migration track can be traced. A very interesting discovery of this research is that at least some of the older fish hole up in coastal ponds during the summer where they conserve energy by remaining relatively inactive. This confirms the reports of fishers that the same fish show up annually.
Female Mallard at nest in pond clearing Down-lined nest had 12 eggs
The first brush pile at Salter Grove was created at the north end of the vernal pond in 2020 with masses of thorny climbers removed from overloaded trees and shrubs in the park. What an exciting surprise to find that a female Mallard duck used it to shelter a nest with 12 eggs in April of 2021!
Since then, brush piles have been mindfully and strategically established throughout the park as volunteers manage the nature trails. These mounds of dried vegetation have become inviting shelters for birds and small mammals.
When placed on sloping terrain, the tangle of branches additionally traps leaf litter and prevents soil erosion. The fall of large branches during a storm in late 2020 provided the material for slope protection at the mid-point of Audubon Trail, where bare soil prevailed.

The payoff for building the elongated brush pile was spotting an American Mink capturing a mouse in the vicinity in July 2021, and then two more sightings in June 2022. The observations of this predaceous mammal on a slope so near Narragansett Parkway were unexpected because the mink’s usual haunts are the marshy shorelines along the breakwater, causeway, and Marsh Trail.
Even plants benefit from the elongated brush pile. The broad-leaved enchanter’s-nightshade, a native species of moist woodland, was seen for the first time in the park in August 2024 upslope at the pile’s southern end! It was likely brought in by a bird that defecated while perching on the brush pile, and no doubt the moist litter-rich environment encouraged the plant to grow where there had been only bare soil.
Broad-leaved enchanter’s nightshade first observed in August 2024
And then, for some unknown reason, this elongated brush pile was completely dismantled in March 2025 by scattering in the understory. Thus, a corridor for safe passage and a wildlife shelter was destroyed.

Friends of Salter Grove has written permission from the City of Warwick’s Tree Warden to manage the vegetation structure of Salter Grove. All branches and foliage cut are formed into brush piles as shelters for wildlife, rather than stuffed into bags for collection. Regular observations of these brush piles indicate that more and more wildlife are using them.
Even if well-intentioned, whenever individuals dismantle established brush piles, create new ones, or otherwise alter the physical infrastructure of the park, on-going management efforts are disrupted.
We are always keen to learn how we can better manage the park to recruit more native species of plants and animals. So let us know your ideas (friendsofsaltersgrove@gmail.com), but please don’t undo what has already been done.
The lower-than-usual rainfall combined with higher-than-usual temperatures during the growing season in 2022 greatly reduced fruit production at Salter Grove to a level not seen in many years. It was alarming because many insectivorous birds and their fledglings include large amounts of fruits in their diet after at the end of the breeding season.

However, the bumper crop of juicy and plump berries this year should convince fruit-eating birds that Salter Grove is a great place to raise their families!
Just two weeks ago, a Baltimore Oriole was already pokoing through ground vegetation to get at fruits of twice-leaved blackberry that creep through low vegetation.

Soon, the hedges of leafy-flowered blackberry, and wine raspberry that line the lawn south of the parking lot will be filled with ripe fruits.

Salter Grove recently hosted high school students who fulfilled their community service hours towards their graduation requirements. The experience proved to be mutually beneficial.

Two equally effective approaches were taken. Starting in late May, Alexandra Dickinson, a senior from Lincoln School in Providence dedicated 40 hours over a two-week period to assist with maintaining the vegetation and signage along the nature trails.
Using both field observations and the Guide to Salter Grove, she learned to identify many of the common birds and plants that occur in the park.

In early June, Cole Robinson and his class of 14 sophomores from the MET High School devoted two hours to: 1) install signage along the Upland Trail, 2) clear vegetation to provide access to a patch of heavily fruiting blackberry, and 3) remove Japanese knotweed throughout the park to deter further invasion.

All of the students were first introduced to the impenetrable patch of Japanese knotweed on Audubon Field. Witnessing the aggressive growth of this introduced species helped them realize how their respective tasks contribute to the overall care of the park.

On June 1st, 2023, 4th- and 5th-graders from St. Peter School walked to Salter Grove accompanied by three teachers and five 8th-grade honor students.

During the 90-minute visit, information from the Guide to Salter Grove was accessed by smartphone to to explore and learn about the ecological assets of the park.
Talking about what will be seen on the nature trails.
Science topics discussed in the classroom came to life for students and teachers alike.
Students recorded observations in journals.
Organized into small groups, they walked along nature trails to observation stations that featured examples of: glacial history and geology of Rhode Island; native versus introduced plants; impact of invasive plants; different kinds of aquatic and terrestrial habitats; tolerance of marsh plants to brackish water; and human impact on the environment.

And all this, from just six of 23 observation stations!

Dr. Susan Unger, the science teacher who organized this field trip, would like to continue using Salter Grove as an outdoor classroom. Future field trips would focus on fewer topics so students can dive more deeply into the subject matter. Instead of simply noting down observations, they could collect data to answer specific questions formulated during classroom discussion.

Early on the morning of May 6th, a group of five explorers began an observational journey through the trails of Salter Grove.
Billy McGovern confers with Anonymous, Stella, Wesley, Gwen, and Michael (L to R, Michael not pictured) about their park exploration.
The youngsters met at a cozy picnic table along Upland trail. They were shown a series of pictures of the same location at different times of the year. The explorers noted how the features of the pictures changed seasonally.
With the pictures in mind, the explorers next set out to find an interesting location in Salter Grove. Having chosen an appropriate spot, they began the process of documenting the area. Armed with pencils, crayons, and markers they drew their chosen location with great detail.
Back at the picnic table, the explorers displayed great enthusiasm while describing the features in their pictures that they found most interesting.

The explorers will keep their pictures in a safe location for a future adventure. During the summer, they will draw another picture of the same location to see how it has changed over time.
This was the second outing of a program being developed by the Friends of Salter Grove. This program aims to show that outdoor recreation and education with minimum technology is fun.
Like Scandinavian forest schools, the program aims to instill a sense of respect for the environment and the importance of having minimal impact while demonstrating how to use a shared space without impairing others’ enjoyment.
