• The Value of Coastal Areas: What is Shore Road Doing for You?

    Shore Road Sanctuary is an eight-acre nature preserve. It features a salt marsh, grassland and wet meadow that is very often partially submerged by water. As you walk there, you may notice birds hidden amongst the grasses and fiddler crabs scuttling along the beach. You might even get lucky and spot a horseshoe crab pulling itself along the sand in shallow waters. A community of prickly pear cactus nursery grows alongside the trail and milkweed plants in the pollinator garden offer a home to the larvae of monarch butterfly. But this preserve does a lot more than provide a habitat for these organisms. Firstly, one of the most important aspects of coastal settings such as this is their role in keeping the water clean. Shore Road Sanctuary is located alongside Cold Spring Harbor, which, in addition to being the home and feeding area of numerous fish, birds and mammals, is a popular boating and water recreation site. All of these species, humans included, depend on the water in the harbor being clean. Natural settings like Shore Road act as buffers between the harbor and sources of pollution like streets and lawns. When it rains, the stormwater will fall in areas like a suburban neighborhood and drain out, eventually to the ocean. As the water drains, it picks up pollutants and carries them along its journey. However, as the water makes its way through Shore Road, the plants in the grassland act to soak up the water and filter out some of those pollutants, preventing them from reaching the nearby harbor. One of the pollutants removed by the grassland plants and the salt marsh is nitrogen. Nitrogen is commonly found in fertilizers used on lawns, as well as in car exhaust. Though it is the most common element in the atmosphere, nitrogen when found in the water can cause harmful algal blooms that destroy aquatic ecosystems. High concentrations of nitrogen in our water supply can also cause birth defects in humans. Plants that are generally submerged in water can actually use nitrogen in the process of respiration in place of oxygen and return the nitrogen to the atmosphere. This process is most pronounced in shallow marshes submerged most of the time. Shore Road is coastal, but if you look at the sands near the low tide line, you’ll notice that they tend to be dark and more like mud. This is an indication that there isn’t much oxygen there and is a good sign that the nearby grasses are helping to remove nitrogen from the area. These dark muddy sands are also indicative of high carbon storage. Marshes and other wetlands actually store more carbon than rainforests. Though it is important to preserve many different types of ecosystems, wetlands like Shore Road have some of the highest potential to help combat climate change. The more coastline that is lost to development, the smaller the world’s carbon storage potential is. Another two-fold impact of Shore Road occurs through the process of chemical weathering. Rocks break up in two ways: physically as wind and water wear away at them, and chemically as acid rain reacts with the rocks it encounters. This process actually helps to deacidify the water in the harbor and contributes to carbon storage. Ions released into the water by chemically weathered rocks bond with loose hydrogen atoms (which are responsible for making things acidic), causing the acidity of the water to decrease. Other ions released by this process contain carbon from acid rain and are used by organisms to build shells and are eventually buried in the sand. In this way, chemical weathering draws carbon from the atmosphere and returns it to the earth over a period of hundreds of thousands of years. Areas such as Shore Road are critically important in providing an array of benefits to mankind. Their preservation is essential to ensuring that we have clean, safe water for ourselves and for other species with whom we share the planet. They also play a major role in effectively responding to and reversing anthropogenic climate change. The next time you visit Shore Road, you may decide to think about it differently.

  • 10 Land Alliance Preserves to Visit

    During these uncertain times, nature can help us slow down and recharge. In fact, the latest research suggests that spending time in nature reduces stress and anxiety.  The Land Alliance currently owns or helps maintain ten preserves open to the public. These properties boast intricate trail systems, diverse ecological communities like salt marshes, wetlands and meadows, and are home to an array of native animal and plant species (some of which are estimated to be over 1,000 years old). Cushman Woods – 28 acres, South end of Still Road, Matinecock (south of Duck Pond Road) Beautiful yellow trout lilies are among the many native plant species that are blooming at the 28-acre Cushman Woods. According to the latest research, the average age of a trout lily colony can be up to 150 years old. They potentially can be over 1,000 years old in undisturbed forests. The trail system at Cushman Woods is the largest of all the North Shore Land Alliance preserves. It boasts several restored carriage trails that were once used for fox hunting. In the 1920s, the property was part of the estate of Paul Cravath, a prominent Manhattan lawyer and partner of the law firm Cravath, Swaine & Moore. It was purchased by the Land Alliance with the invaluable support of Verena and Roderick H. Cushman in 2016.  There is a small parking area at the entrance to the preserve. Hope Goddard Iselin Preserve – 42 acres, Chicken Valley Road, Upper Brookville The Hope Goddard Iselin Preserve is home to beautiful sugar maples (the New York State tree), a colorful meadow and white pine forest. Red fox, box turtles, Eastern screech owls and red-tailed hawks are just a sampling of the animals that inhabit there. The preserve used to contain two fields, a portion of which remains, that were farmed by the Youngs family. Farming there was discontinued in the 1960s due to lack of irrigation. Who is Hope Goddard Iselin? Mrs. Iselin was an American heiress, sportswoman and conservationist who, in 1931, gave the Village of Upper Brookville its name. The 42-acre preserve was named after Mrs. Iselin as it used to be part of her exquisite 160-acre estate, Wolver Hollow, which was built by her and her husband in 1914.  The preserve contains a one-mile interpretive trail and parking for four to five cars. Cordelia H. Cushman Preserve – 15 acres, Southside of Route 25A across from Yellow Cote Road, Oyster Bay Cove A dozen native plant species protected by New York State make their home at the 15-acre Cordelia H. Cushman Preserve. There you may spot lovely pink lady’s slipper, spotted wintergreen or dwarf rattlesnake plantain (a low-growing wildflower). Protecting native plants is crucial because they are the foundation of healthy wild ecosystems. Over 100 years ago, part of the Cushman property was used to raise racing horses. The land was acquired by Mr. and Mrs. Paul Cushman in the 1930s. In 1973, their son Roderick Cushman donated 15 acres to The Nature Conservancy (TNC). TNC has since donated the property to the Land Alliance. The woodland there has not been forested for generations. Trails follow a nice short loop, with moderate elevation. There is a tiny parking area, which can be accessed off Route 25A. Shore Road Sanctuary – 8 acres 95 Shore Road, Cold Spring Harbor A thriving grassland, saltwater marsh, beach and wet meadow comprise the eight acres that is Shore Road Sanctuary. These diverse ecological communities attract and support countless wildlife and native plants, including a variety of birds, butterflies, horseshoe crabs, warm-season grasses, sea lavender and more. The preserve did not always look this way. It was operated as a petroleum fuel distribution terminal from 1924-2003! ExxonMobil completed the removal of the storage tanks and buildings from the harbor-front property in 2010 and soil remediation followed. The property was donated to the Land Alliance in 2012. The preserve, which contains a small parking area, lies within a New York State-designated Significant Coastal Fish and Wildlife Habitat and National Audubon Society-designated Important Bird Area. The loop trail that winds through the grassland is enhanced by educational signage. John P. Humes Japanese Stroll Garden – 7 acres, Dogwood Lane, Mill Neck This unique and historic 7-acre gem of landscape design and woodland is home to an impressive collection of North American and Asian plants that constitute a beautiful Japanese landscape. They impart a meditative experience. Take a stroll down the stepping-stone path and you’ll see bamboo groves, Japanese cedars, Yakushima rhododendron, a koi pond and an authentic Japanese teahouse. The Garden was created by Ambassador and Mrs. John P. Humes following a visit to Japan in 1960. They hired Japanese-American landscape designer Douglas DeFay and his wife, Joni, to design the garden on their Mill Neck estate. The Land Alliance purchased the property in 2017 for conservation purposes. The acquisition of this parcel completes a conservation corridor that stretches over 150 acres in the middle of the Beaver Brook watershed. It effectively links the Stroll Garden and larger Humes property (also owned by the Land Alliance) to Shu Swamp and the two Francis ponds. Corridors like these are crucial for movement of wildlife, as they prevent inbreeding or reduced genetic diversity. The garden opened in May this year for the season. For more information, please visit our website at www.northshorelandalliance.org. Red Cote Preserve – 30 acres, Yellow Cote Road off Route 25A, Oyster Bay Cove This 30-acre property contains a spacious parking area. It boasts woodlands, scenic trails and two large wildflower meadows that seasonally burst with color and the hum of insects like the Monarch butterfly, (a species whose numbers have declined over 80 percent since 1990 and is now at risk of extinction). Meadows can be biodiversity hotspots, hosting scores of different species of wild flowers and/or grasses that support a myriad of insects, which in turn support many birds and other small animals. In addition, they capture vast amounts of carbon and help mitigate flooding by holding onto rainwater. Three Eastern red cedar trees that are estimated to have grown to nearly 70 feet in height can be found in the western meadow. These trees are native to Long Island and can live for over 1,500 years. Red Cote Preserve was used for farming for many decades. Aerial photographs from the 1920s show farm fields with narrow hedgerows of trees between them.   The North Shore Land Alliance manages this preserve under a stewardship agreement with Nassau County. Tiffany Creek Preserve – 200 acres, Sandy Hill Road at Berry Hill Road, Oyster Bay Cove A mix of ecological communities can be found on this spectacular 200-acre preserve, such as old growth woodlands and oak forest, extensive fields, freshwater wetlands and a large pond. The last of which was acquired by Nassau County with Environmental Bond Act funding. The preserve lies within the Oyster Bay Special Groundwater Protection Area, Nassau County’s largest SGPA. Protecting undeveloped land, whether at this preserve or at any of the Land Alliance preserves, is critical to protecting Long Island’s sole source aquifer. This large piece of property is surrounded by an additional 250 acres of privately protected lands, which enhance the conservation values found there. Nassau County acquired the parcels of land that makeup Tiffany Creek Preserve from the John M. Schiff family in 1992 with help from The Nature Conservancy.  The Land Alliance stewards 14 meadow acres of the preserve. Fox Hollow Preserve – 26 acres, Route 25A near White Oak Tree Road, Laurel Hollow This beautiful 26-acre preserve contains an unusual variety of distinct forest types that feature a diversity of oak, beech and other hardwoods; white pine woodland and shrub layers dominated by mountain laurel and maple-leaved viburnum. The diversity of trees and other plants attracts many different bird and other wildlife species to the preserve. Take a stroll there down the hilly trails, which contain some of the steepest sections of trail in Nassau County. Depending on the time of year, you could easily spot or hear great horned owls, red-bellied woodpeckers, a diversity of warblers and red-tailed hawks. Fox Hollow used to be part of a 1,000-acre farm. In the 1920s the field was planted with white pine trees and in the 1930s the site was turned into an equestrian center. Fox Hollow is part of the Route 25A Heritage Area and also located in a state-designated Special Groundwater Protection Area. Groundwater recharge occurs on Long Island when precipitation seeps into permeable ground and replenishes the underground aquifer, the sole source of Long Island’s drinking water. Protecting open space is critical for protecting drinking water. In 2012 The Nature Conservancy donated the preserve to the Land Alliance. Fox Hollow welcomes visitors arriving by foot. No designated parking is available at this preserve. You can walk or bike or park at the nearby Cushman Preserve. Wawapek – 32 acres, 3 Mowbray Lane, Cold Spring Harbor A thriving grassland, saltwater marsh, beach and wet meadow comprise the eight acres that is Shore Road Sanctuary. These diverse ecological communities attract and support countless wildlife and native plants, including a variety of birds, butterflies, horseshoe crabs, warm-season grasses, sea lavender and more. The preserve did not always look this way. It was operated as a petroleum fuel distribution terminal from 1924-2003! ExxonMobil completed the removal of the storage tanks and buildings from the harbor-front property in 2010 and soil remediation followed. The property was donated to the Land Alliance in 2012. The preserve, which contains a small parking area, lies within a New York State-designated Significant Coastal Fish and Wildlife Habitat and National Audubon Society-designated Important Bird Area. The loop trail that winds through the grassland is enhanced by educational signage. Louis C. Clark Sanctuary – 8 acres, Valentines Lane near Longridge Lane, Old Brookville This eight-acre preserve is one of the Land Alliance’s most ecologically diverse preserves. It contains a mix of upland forest and freshwater wetlands, with trails traversing the narrow strip of woodland separating Valentines Lane from the wetland in the northern parcel. Over the past 130 years, the Long Island Sound area has lost 31 percent of its tidal wetlands (according to the U.S. Fish and Wildlife Service). Despite tidal wetland legislation passed in the 1970s, wetland decline in Long Island Sound continues. Over 100 bird species make their home at this preserve and nearby James Preserve. According to the latest research, there are three billion fewer birds in North America than there were 50 years ago; protecting open spaces like these helps protect critical bird habitat. There are also several species of fish, frogs and turtles that inhabit the property. Prior to its protection, this land belonged to a larger parcel known as Valentines Farm. Louis C. Clark Sanctuary was donated by Frances S. Weeks to The Nature Conservancy in 1965 in memory of her son Louis Crawford Clark. TNC donated the property to the Land Alliance in 2012. Louis C. Clark Sanctuary has a tiny parking area and welcomes visitors arriving by foot.
