Irish Grove MOS Sanctuary
4110 Rumbly Point Road, Marion Station, MD 21838
Irish Grove MOS Sanctuary in Somerset County is considered by many to be the “jewel in the crown” of the MOS Sanctuary System, and is by far the largest of the ten MOS sanctuaries. Irish Grove Sanctuary occupies the Rumbly Point peninsula in southern Somerset County. The sanctuary now consists of 2,285 acres, the majority being tidal marshes, with some higher ground in pine forests. There are breathtaking, wide-open vistas of the tidal marshland. Most of the property is less than five feet above sea level. There are several fresh and salt water ponds surrounded by Loblolly Pine woods.
Irish Grove Sanctuary began with a purchase by MOS of 1,409 acres in 1968. MOS engaged in a massive fundraising campaign to enable this purchase, and donations were received from many community organizations and school groups, as well as MOS members. Additional parcels were added over the years, both by purchase and by donation through the Eastern Shore Land Trust. In fall 2017, MOS purchased an additional 32-acre parcel and named it the Chandler and Eleanor Robbins Tract, in honor of these two late members of MOS who did so much to support MOS and its sanctuaries, and in particular, Irish Grove. Now MOS is celebrating the recent (November 2019) addition of several tracts totaling 675 acres, a generous gift from Mr. Beverly M. DuBose, a local landowner and outdoorsman. Mr. DuBose and his associates in the Quindocqua Partnership have been good friends to MOS and the Irish Grove Sanctuary. The DuBose addition includes the spectacular Richardson Marsh that covers most of the south end of Rumbly Point.
The sanctuary features a farm house and outbuildings, surrounded by about 20 acres of fields and yard, and this is where visits should start. There are foot trails that start from the house area, as well as a couple of lanes (Dotty Lane, Canal Road, Robbins Way, and Round Pond Road) that can be driven by car during dry weather. There is a screened picnic shelter for use in summer.
Every visit should include a walk or drive down Rumbly Point Road past Richardson Marsh to the road’s end at Rumbly Point on the Pocomoke Sound. The road provides excellent views of the adjacent marsh, a good place to look for waders, shorebirds, terns and gulls, and marshland sparrows and wrens. There is so little traffic that it is possible to simply stop on the road to look at birds. But be aware that the road may not be passable during high tides or after recent storms or high winds.
Irish Grove is very large, and most of the sanctuary’s marshlands, with miles of shoreline and tidal creeks, are not visible from the road or the foot-trails, so the sanctuary is best explored by kayak or canoe (bring your own; none on site). These can be launched in a man-made canal at the end of the sanctuary’s fittingly-named Canal Road, about 0.6 miles past the house. The canal connects to East Creek and thus provides access to much of the marsh. There may not be enough water to float even a kayak at some low tides, so be aware of the tides. Another launch point is at the public Rumbly Point Boat Launch at the south end of Rumbly Point Road. If you decide to paddle, consult a tide chart and use a handheld GPS or a GPS app on your smartphone to avoid getting misplaced in the meandering creeks of the marsh.
June through September are great months for insects at this sanctuary. There are deer flies, green heads, mosquitoes, ticks, and punkies by the thousands. It is advised that visitors during the summer and early fall wear head nets, long sleeve shirts, long pants, closed-toe shoes, and use repellants. Often the insects are worse in the upland areas; once out on the marsh, the breeze may keep them away. Weather is typically mild year-round due to persistent breezes and the proximity to Pocomoke Sound.
The MOS official checklist for Irish Grove includes 248 species that have been observed there; over 230 species are recorded on eBird. There is a separate eBird hotspot for Rumbly Point with 206+ species. Irish Grove is the #1 eBird hotspot for Somerset County.
The avifauna is typical of salt marshes and adjacent uplands. The marshes have rails, ducks, shorebirds, Marsh Wrens, marsh sparrows, and other species that would be expected in salt marshes. The uplands have breeding species typical of southern pine forests and forest edges: for example, Chuck-Wills-Widow, Pine Warbler, Blue Grosbeak, Summer Tanager, Brown-Headed Nuthatch. Breeding birds in the marshes include Saltmarsh and Seaside Sparrows, Willets, and rails. Also found in the marshes are migrating Yellow Rail (rare) and shorebirds; wintering Sedge Wrens, Short-Eared Owls, sparrows, ducks, and shorebirds.

DNR states that “Richardson Marsh contains high quality occurrences and one of Maryland’s best examples of the Iva frutescens / Spartina patens tidal shrubland” (See https://dnr.maryland.gov/wildlife/Documents/natcommstidal.pdf, pages 83 – 86). ◾ Irish Grove MOS Sanctuary is included in the larger Somerset-Wicomico Marshes Important Bird Area as designated by the National Audubon Society. ◾ The local chapter of the Maryland Ornithological Society is the Tri-County Bird Club, serving Somerset, Wicomico, and Worcester Counties. The club hosts field trips in the region as well as meetings with informative presentations, all free and open to the public. ◾ The Tri-County Bird Club and MOS host annual working weekends at Irish Grove, when routine maintenance and improvements are accomplished at the property. All are welcome to come out and give a hand.
