Marsh Madness: Restoration of Iona Marsh from Invasive Phragmites

Iona Island, located along an elbow of the Hudson River in Bear Mountain State Park, is technically an archipelago of three islands connected by marshlands. Iona has had many owners in its storied history, prior to being bought by New York State in the 1960s. The Island was host to Native American tribes for thousands of years, who took advantage of the plentiful shellfish along its shores. In the last few hundred years, it has been the site of an unsuccessful vineyard, a hotel and weekend destination for NYC residents, a U.S. Navy arsenal, and a partially built park recreation area. The eastern side of the island past the railroad tracks has been closed to the public since the 1980s, but a small portion of the island consisting of the five remaining Navy buildings is used for storage for the Palisades Interstate Park system. The rest of the island has returned to a more natural state of woods, meadows, and rocky outcroppings and serves as a sanctuary for wintering bald eagles.  The island achieved National Natural Landmark status in 1974, and was designated a NYS Bird Conservation Area and Audubon Important Bird Area shortly thereafter.

A key natural feature at Iona is the extensive marshlands, 153 acres in all, flanking its western side.  Part of the Hudson River National Estuarine Research Reserve (HRNERR), this brackish tidal marsh (marshes with water that has different concentrations of salt depending on the tides) teams with life including fish, waterfowl, waterbirds, plants, and crustaceans. In recent times, the rich biodiversity of the marsh, including a number of state rare species, has been threatened by Phragmites australis, or as it is more widely known, common reed.

Common reed (Phragmites australis) is a plant that was likely brought to the US from Europe and Asia in the 1800s through ship ballast or the water taken in by ships to allow them to balance on long voyages. Commonly referred to as just Phragmites, this non-native plant is invasive in the U.S., displacing and crowding out native plant species, such as cattails, rushes, asters, and many others. In turn, the presence of this species has undermined the complex web of marsh dependent organisms.

The non-native Phragmites is identifiable by its tall stature, dark blue-green leaves, and tendency to form dense stands, with little to no possibility for native species to grow in the areas that they occupy. A native species of phragmites (Phragmites americanus) occurs in NY as well, but this smaller plant with reddish stems grows with less density so it does not crowd out other flora.

The phragmites problem at Iona Marsh began in the early 1960s, when the first small colony appeared near a pipe draining into the marsh. Over the next 40 years, phragmites steadily expanded until it covered nearly 80 percent of the marsh area. Researchers tracking these changes noted a concurrent decline in marsh specialist birds and specialized brackish marsh plants, including state rarities.  In an effort to reverse these trends, the Palisades Interstate Park Commission, while partnering with Hudson River National Estuarine Research Reserve and the Highlands Environmental Research Institute, started a New York State Department of Environmental Conservation (NYSDEC) funded management program in 2008 focused on a 10-acre test area. The goal was to reduce the invasive phragmites, and make room for native plants to once again occupy the area. If the program was successful in this small area (1/15th of the marsh), it could be expanded to additional marshlands.

A multi-faceted control and monitoring program has been developed and implemented and the results have been dramatic. More than 90% of the phragmites was eliminated within one year and nearly 97% by the third year. Researchers saw the return of huge meadows of annual native marsh plants, including some state-threatened species, followed by perennial cattail stands. Marsh specialist birds such as Virginia rail, least bittern (State-threatened), and marsh wren followed soon thereafter.  Based on this success, the project was expanded to an adjacent 32-acre area of the marsh known as Ring Meadow. Both areas now have less than five percent Phragmites cover, an overall success on the journey to reestablish native vegetation.

While complete eradication of the Phragmites may be impossible to achieve, success can be maintained through continued monitoring and spot treating remaining and new patches.  Bird and vegetation surveys are conducted annually, as are measurements of sediment build-up on the marsh surface, as it relates to sea level rise.  The goal remains to restore the native plant communities in the marsh to promote biodiversity. A healthy, native marsh community will lead to increased productivity and habitats for fish, birds, and mammals – many of them specially adapted to the brackish conditions at Iona.  With continued management, the long-term outlook is positive for this Hudson River jewel, one of only four large brackish marshes on the Hudson.

Interested in seeing Iona Marsh for yourself? While public canoeing and kayaking are not allowed in the marsh itself to protect this unique place, through collaboration with the State Parks, NYS DEC offers free public canoe programs each summer.  Not a fan of getting on the water? Iona Island is accessible by road. There is a parking lot approximately ½ mile onto the island, right before the railroad tracks (the boundary of the public accessible areas), where you can park and view the marsh. Lucky visitors may spot waterfowl, muskrats, frogs, turtles, wetland birds, deer, or even bald eagles!

There’s Fungus Among Us!

As part of my duties as an Invasive Species Project Steward, it has been my pleasure to join the Forest Health Specialists in their fieldwork. The Forest Health Specialists travel to priority park lands throughout the region to survey and monitor for forest pests, with an emphasis on areas previously treated for pests and on early detection of emerging threats to forest health. Although our focus in these surveys have been hemlock woolly adelgid, southern pine beetle, and spotted lanternfly (see DEC website or email invasives@parks.ny.gov for more information), we see so much more in our state’s lush woodlands. Spending time in wild spaces and amongst such biodiversity ignites a sense of curiosity that no number of office supplies can replicate. Dendrology (the study of trees and shrubs), entomology (insect study)  herpetology (the study of reptiles and amphibians), ornithology (bird study) – with all these -ologies everywhere you turn, how can you ever pick just one to invest your energy in learning about? The more time I spent hunting for the aforementioned pests, I found myself increasingly drawn to the study of one particular organism: mushrooms. Maybe I liked how they can be beautiful and disgusting, delicious and deadly, beneficial or parasitic, and all share a space within the field of mycology. Whatever the reason, I found them fascinating and had plenty of run-ins with them.

ChickenOfTheWoods_Taylor Conte
Chicken of the Woods found at Mills Norrie State Park.

One particularly distinct and common mushroom is chicken of the woods, scientifically named Laetiporus sulphureus. It is also called sulfur shelf because of the sulfur-yellow color of the pores, and its overlapping disk-like growth form protruding from oak, hemlock and other trees like a shelf. Each lobe is an inch thick, up to 20 inches across and can weigh up to a pound apiece! It is very common in our neck of the woods- the specimen pictured here was found at Waterson Point State Park in the Thousand Islands, though I have also seen it at Minnewaska State Park, John Boyd Thacher State Park, and Harriman State Park.

hooffungus_taylor-conte.jpg
Hoof Fungus growing on a tree at Minnewaska State Park.

Another fungus you may see protruding off a tree, often birch, is the hoof fungus (Fomes fomentarius), named as such for the hoof shape and hardness of the brown-ringed cap (Roberts and Evans, 383). It has also been called tinder polypore because “amadou,” the inner fibrous flesh, was historically used as tinder to start fires and cauterize wounds (Lincoff, 457).

 

 

 

 

Cinnabar-RedPolypore_Taylor Conte
Underside of Cinnabar-red Polypore at Harriman State Park.

Also in the polypore family, Polyporaceae, is the Cinnabar-red polypore (Pycnoporus cinnabarinus) pictured below. The distinct red caps are 1-5 inches wide and round, often growing on dead deciduous trees (Lincoff, 486). Another member of Polyporaceae is the violet toothed polypore (Trichaptum biformis). They have round, overlapping caps up to 3 inches wide with a leathery texture and are brown with purple, wavy margins. They are found by the hundreds on deciduous trees, and over time will diminish them into sawdust (Lincoff, 490)!

FalseTurkeyTail_Sara Mitsinikos

False turkey-tail (Streum ostrea) is another fungus often growing on downed deciduous trees, although not a member of Polyporaceae. Its name stems from often being misidentified for the fungus turkey-tail (Trametes versicolor), which is a polypore (Lincoff, 497). The species name ostrea is Latin for “oyster,” the shape of the tan, tough and papery caps, often tinted green with algae (Roberts and Evans, 438). Research indicates that they produce laccase, an enzyme used to break down contaminants.

inkycap_taylor-conte.jpg
Inky Cap at Mills Norrie State Park. The bottom of the cap is showing signs of the liquifying gills, or ink, within for which it gets its name.

This common inkcap, Coprinopsis atramentaria, was found at Mills Norrie State Park along the Hudson River. The name atramentaria comes from the Latin word “atramentum,” meaning ink (www.first-nature.com). The French mycologist Jean Baptiste Francois Pierre Buillard, who first described the species and named it, realized that the gills turn to a liquid with age and can be used to make ink. The cap is light gray, thin and shaped like a partially opened umbrella with a smooth white stem and can be found growing on stumps, roadsides, and gardens.

Chanterelles_Taylor Conte
Chanterelles growing at Schunnemunk State Park.

Keep a lookout on your woodland adventures for the highly sought-after chanterelles (Cantharellus cibarius), also called golden chanterelles for their yellow-orange coloration. They have smooth stems that widen at the top to a funnel-shaped cap with gills on the underside and a smooth top with wavy edges. This is one of the best-known mushrooms and is exported commercially worldwide (Roberts and Evans, 476). The ones pictured here were found at Schunnemunk State Park in the Hudson Valley.

Puffballs_Sara Mitsinikos

In your exploration of State Parks, you are likely to stumble upon puffballs, family Agaricaceae, growing in the leaf litter. They are round to upside-down-pear shaped, sometimes with a grainy texture and usually 3 inches tall and 2 inches wide. They are called puffballs because as they mature, a hole opens on the top of the rounded cap that enables the spores to puff out. Historically, they were used to seal wounds, start fires, and stun bees as we use smoke today. But be cautious around them, their spores are known to irritate the nose and eyes, and if breathed in excess can cause an allergic reaction in the lungs called lycoperdonosis (Roberts and Evans, 520). The puffballs pictured below were sighted at Taconic Outdoor Education Center in the Hudson Valley. The giant puffball (Calvatio Gigantea) is a particularly interesting variation that has been seen on State Parks’ land. As its name implies, they are round, smooth and typically 30 inches by 30 inches. The largest recorded, however, was up to 5 feet wide and weighed in at over 40 pounds (Roberts and Evans, 512)!

WhiteSpindles_Sara Mitsinikos

Then there’s the coral mushrooms, named for their resemblance to undersea coral colonies. These white spindles (Clavaria fragilis) were found growing in the leaf litter at Minnewaska State Park Preserve in the Hudson Valley. The species name fragilis pays homage to the extremely brittle nature of the fungus (Roberts and Evans, 486). It used to be called Clavaria vermicularis, white worm fungus because of its tubular white spines growing upwards in a cluster (Lincoff, 400).

goldenspindles_sara-mitsinikos.jpg

It’s relative, golden spindles (Clavulinopsis fusiformis) is also a saprotroph, meaning it feeds on dead matter like leaf litter (Roberts and Evans, 494). Golden spindles also grow in unbranched needles, but as the name implies, are yellow.

whitecoralclusters_sara-mitsinikos.jpg

This white coral (Ramariopsis kunzei) was also found growing in the leaf litter of the forest floor at Minnewaska State Park. Unlike the spindles, the fruitbodies of the white coral are branched. There is still much to be learned about this species (Roberts and Evans, 504).

LionsMane_TaylorConte
Lion’s Mane from Minnewaska State Park.

A much shyer mushroom, despite the name, is lion’s mane (Hericium erinaceus). It is also called bearded tooth, as it grows downward from trees or logs in a cluster of white spindles up to 3 inches long. Similar to human teeth, it yellows as it ages. In Asia it is called monkey head and is used to strengthen the immune system, available as a pill for stomach ulcers or as a tonic drink in a can (Roberts and Evans, 468). The cluster shown here was found at Minnewaska State Park.

Mushrooms like moisture and cool temperatures, so now is the time to seek them out. I am sure you will have no trouble finding them, and although they can be very tricky to identify, perhaps you may recognize some of the species featured here on the many trails located at our State Parks. Happy Mushroom hunting, but remember not to disturb them, as they are a much-needed member of the ecosystem.

Excelsior Conservation Corps Works Alongside Parks to Conserve Historical Site

The New York State Office of Parks, Recreation and Historic Preservation (State Parks) staff members at Ganondagan State Historic Site recently worked with members of the Excelsior Conservation Corps (ECC). The ECC is a non-profit organization within the Student Conservation Association (SCA). The members involved in this program range from ages 18-25 and learn skills and methods to help restore, protect and enhance New York’s natural resources and recreational opportunities.

Ten members of the ECC were tasked with invasive plant species removal from various locations and GPS monitoring of certain invasive plant species within the Ganondagan State Historic Site located in Victor, NY. Invasive plant species are non-native species that can cause harm to the environment, the economy, or to human health. Because these plants are not native in these habitats, they can cause or contribute to habitat degradation and loss of native species.

Wild Parsnip

Giant hogweed (Heracleum mantegazzianum), which is a tall flowering invasive plant that is infamous in many areas of New York, not only disrupts the environment in which it grows but can also be very harmful to humans. If the sap from the stem comes into contact with the skin, it can cause severe burns and make skin more sensitive to ultraviolet radiation provided from the sun.  Fortunately, no giant hogweed has been found at Ganondagan State Historic Site, but the site has become a host to a closely related and invasive plant called wild parsnip. Wild parsnip (Pastinaca sativa), has similar effects to giant hogweed when it comes into contact with unprotected skin.

When the members of the ECC arrived, they were informed they would be participating in the Parks’ annual wild parsnip picking day. Each year the staff members from the Environmental Field Office dedicate one day to pick as many wild parsnip plants as they can in hopes of clearing out fields and minimizing the possibility of more growing in the future. Everyone was instructed to wear long sleeve shirts, pants and gloves in order to protect their skin. Starting early in the morning, the group of 10 ECC members joined forces with six State Parks’ staff to venture out into the fields of wild parsnip. Throughout the day everyone hiked through trails and sections of the property, pulling the plants out and piling them up they could be removed from the area. The members were instructed to get as close to the ground as possible to pull the roots up by hand. After walking through 30 acres of fields, the total tally of plants removed came out to be 13,439!

After the wild parsnip adventure, there was still more for the ECC members to do at Ganandogan. State Parks has been closely monitoring a field full of invasive plants for the past few years with GPS devices.  These devices enable the staff to map the location and the amount of invasive plants within the area. The ECC team helped record data on six different plants while walking across a 70-acre field. To cover the area efficiently, the ECC members were required to stand in a line about 14 paces apart and walk due North across the field in a straight line, using compasses as their guide. Staying straight was not easy while walking over hills and through tall grass, stepping over and through every obstacle in their path.

The plants they were looking out for were Canada thistle, bull thistle, multiflora rose, autumn olive, swallowwort and non-native honeysuckles. Each observer would stop at every 15 paces to observe the area they were in and mark each location for any of these six invasive plans within a five-foot radius. In total, the team collected over 20,000 points that will be used to create maps in ARC GIS to show the extent of the invasives and to help guide management plans.

The Ellenville Fault Ice Caves – A National Natural Landmark

The most popular features of the Sam’s Point Area of Minnewaska State Park Preserve are the Ellenville Fault Ice Caves. This remarkable system of crevice caves fills up with ice and snow each winter, and retains some of its ice well into the summer. Even when the ice is completely gone, the caves remain cool all year round. This unusual phenomenon has drawn people to the caves for generations.

Postcard
A postcard from c. 1909 showing the snowed-over entrance to one of the caves. The man in the image is an illustration, and slightly exaggerates the scale.

The significance of the caves has even been recognized by the National Park Service. In 1967, the NPS designated the Ellenville Fault Ice Caves as a National Natural Landmark. This designation is given to natural sites that exemplify the special or unique biological or geological features of a region.

Geologically, the Ice Caves are unlike other caves in the Northeast. Most cave systems are made of limestone, which is easily eroded and dissolved by water. This results in the large, open caverns that most people imagine when they think of caves. The Ellenville Ice Caves, on the other hand, are formed out of extremely hard and insoluble quartz conglomerate. When underlying rock layers were folded by tectonic movement, the hard conglomerate separated along existing joints in the rock.

The caves remain cold because of the natural refrigeration system that exists within them. When air moves across the top of the crevices, the colder, heavier air sinks down into them. The cold air then becomes trapped in the caves, keeping them at a comfortable temperature even during the hottest days of the summer.

While they received the National Natural Landmark designation because of their unique geologic importance, the Ice Caves have a great deal of ecological impact as well. The NY Natural Heritage Program recognizes the ice cave talus community as globally uncommon and rare in the state and a priority for protection. Because of their cold microclimate, the Ice Caves are home to several species that are infrequent in the region. These include goldthread (Coptis trifolium), mountain ash (Sorbus americana), and black spruce (Picea mariana), among others. Scientists have also taken interest in the presence of a species of cave-dwelling crustacean (Stygobromus allegheniensis) that is only found in four states: New York, Pennsylvania, Maryland, and West Virginia. This little arthropod lacks eyes, as it does not need them in complete darkness. It is also able to survive being frozen, a necessary attribute for surviving winter conditions in the caves.

Espinansa et al. (2015)

The Ice Caves have local cultural significance as well. Many residents of the Shawangunks remember the days of “Ice Caves Mountain,” when the Sam’s Point area was managed very differently than it is today. From the late 1960s to the early 1990s, much of Sam’s Point was privately owned and operated as a tourist attraction. Visitors could drive their cars right up to Ice Caves, while a pre-recorded cassette tape described the various features encountered along the way. Doors were placed over the caves to keep the ice inside year-round, and the ice was lit up by multicolored flood lights. A rock wall was built on the cliffs of Sam’s Point to dissuade visitors from getting too close to the edge. While it may have been somewhat kitschy by today’s standards, it cannot be denied that “Ice Caves Mountain” was an important step in allowing the greater public to experience this previously obscure natural wonder.

Many things have changed since the Ice Caves Mountain days. While Sam’s Point is still managed for recreation, there has also been a large shift in focus towards conservation. Visitors may no longer drive through the park, and the cave doors have been removed in favor of letting the natural ice cycle of the caves take place. Interpretive displays within the park focus on the natural history of the caves, rather than just their physical spectacle.

While National Natural Landmark status highlights the importance of a site, it is up to the owners of that landmark to manage and protect it. Fortunately, Sam’s Point is part of a Park Preserve, meaning that all of the plant and animal life within it is protected. As such, those who appreciate the cultural, geological, and ecological significance of the Ellenville Fault Ice Caves are able to experience them to the fullest extent.

Frogs and Pollywogs in NYS Parks

It’s time – hop in the car or on your bike and head to a State Park near you! While you’re there, be sure your ears are open and your eyes are peeled for some awesome amphibian friends! It’s a good opportunity to find out which of the 11 frog species found in New York State are living in our State Parks.

Frogs are amphibians, meaning they live on both land and under water. When females lay eggs, it typically occurs in a nearby pond. The jelly-like egg masses hatch into tadpoles (pollywogs) with round bodies and long finlike tails. Tadpoles develop gills so they can breathe underwater just like fish do! Through a lifecycle process known as metamorphosis, the tadpole begins to develop legs, bulging eyes and air-breathing lungs. All the while the long slender tail starts to shrink and eventually disappears. This frog can now survive on land, breathing in the fresh summer air!

FrogLifeCycle

Frogs spend most of their time underground, hanging out in trees, or in the water. On warm summer nights they will emerge from hiding and head to nearby ponds, lakeshores and wetlands. When trying to identify frog species remember to consider the following: coloration, patterns, skin texture (moist or dry), presence or absence of webbing between the toes, and more. If you can’t see your amphibian friends, but you can hear them, take this time to record its unique call and try to identify it when you get home!

Here are just a few of the frog species found in our State Parks:

Northern Spring Peeper (Pseudacris c. crucifer)

Peeper

The tiny spring peeper can range from a rusty brown to a greenish-gray with a distinct dark X or cross on its back. Its skin is smooth and the belly is cream-colored. This species is also known for hanging out in trees, with its unwebbed toes and sticky pads. Spring Peepers breed earlier in the season than other frog species. If you’ve ever spent an evening camping or sitting by the water, you’ve probably heard their infamous “PEEP” or call.

American Bull Frog (Rana catesbeiana)

BullFrog
American Bull Frog, accessed from https://commons.wikimedia.org/wiki/File:American_Bullfrog_(Rana_catesbeiana)_(8741684912).jpg.

The bull frog is the largest frog in North America, reaching lengths of 6 to 8 inches. It’s a brownish-green color with dark colored bands or blotches on its hind legs. Unlike the treefrogs, the bull frog has webbed hind feet. They’re often found near permanent waters with lots of vegetation. This species size and carnivorous diet allows it to munch on creatures such as snakes, bats, ducklings and other frogs! Behind the bull frog’s eyes are eardrums known as tympanic membranes. The size of these membranes can be used to determine if the frog is a male (it’s larger than the eye) or a female (the membrane is the same size as the eye). Look for this species between mid-March and mid-July. They may startle you with their really load “croak”.

Green Frog (Rana clamitans)

Do you see the Green Frog? Photo by NYNHP.

This is one of the most common frogs across NY State. It is similar to but smaller than a bullfrog. Like the bullfrog, the green frog is brownish-green with bright green on its face and spends most of its time in and near ponds and wetlands. The adults are 3-4 inches long and breed from May to August. Their regular call goes “boing” like the sound of a plucked rubber band or banjo sting. They also have an alarm call, a loud squeak, that you will hear if you scare them into the water. Move slowly towards the edge of the pond to look for these critters and be ready when they squeak and leap into the water!

The northern cricket frog is the smallest and most rare frog species in NY. It is listed as endangered in the State of NY. Adults reach about 1 inch in length, but despite their size, can jump about 5 to 6 feet. Eastern cricket frogs are brown to dull green in coloration with a triangular marking between the eyes. These frogs love shallow ponds with lots of floating vegetation. It has an unusual call, described as two pebbles being clicked together repeatedly. View the northern cricket frog conservation guide created by the New York Natural Heritage Program.
