Eclipse of the Beaver Moon

2 Comments

Starting in the wee hours of Friday, November 19, the upcoming Beaver Moon eclipse will be the longest partial lunar eclipse in six centuries, clocking in at nearly 3 ½ hours. Visible throughout North American, this celestial occurrence also is a reminder that stargazing nights are among many events available at State Parks, some of which have relationships with local astronomy clubs.

But to start, a naturalist question: Why is this upcoming full moon that will undergo this eclipse called the Beaver Moon? Well, according to state DEC naturalist Tom Lake, this description originates with the Indigenous peoples of the Northeast, who in November observed that beaver would stock up provisions to get through the coming winter when ponds, lakes, and other waterways freeze over. Beaver instinctively collect forage, including branches, limbs, even small trees, dragging it into their ponds, and securing it on the bottom for later retrieval as needed during the cold and ice of mid-winter.

Now, what about this lunar eclipse? What will happen, when will it happen and how best to observe it? According to the National Aeronautics and Space Administration, during the peak of the eclipse, the earth’s shadow will cover 97 percent of the moon’s surface, likely casting the moon in a dark, rusty reddish color.

The partial eclipse phase will last 3 hours, 28 minutes and 24 seconds, making it the longest partial eclipse in nearly 600 years! But to see this cosmic dance of earth, moon and sun unfold, two things are needed: Clear nighttime skies and a willingness to be awake when most people normally are asleep.

When the eclipse starts at 1:02 a.m. on Nov. 19, as the earth begins to pass between the sun and the moon, the changes initially will be subtle and difficult to see. That is because the earth actually casts two types of shadows _ a lighter, broader shadow known as the penumbra and a full, dark shadow, called the umbra. After initially entering the penumbra, the full moon will start entering the umbra at 2:18 a.m., gradually darkening and reddening until maximum eclipse is reached at 4:02 a.m. The moon then will start exiting the umbra, followed by the penumbra, until the eclipse ends completely at 7:03 a.m.

No special equipment is needed to safely observe a lunar eclipse, unlike a solar eclipse, which should never be looked at directly without special protective gear. A pair of binoculars can reveal more detail of the moon’s surface. For photography buffs, NASA has tips here for how to best photograph the moon and eclipses.

In State Parks’ Long Island Region, several Parks will remain open for those who want to observe the Beaver Moon eclipse. A requirement for a stargazing permit, which is normally needed to be in those parks after normal operating hours, is being waived for this event.

Long Island State Parks that will remain open for viewing are:

Upstate, the light pollution that present around metropolitan New York City is not as much of an issue, so finding a place to see the eclipse will be relatively simple.

Some of the darkest night skies in the New York are found in the Adirondack Region, and the John Brown Farm State Historic Site outside of Lake Placid will be open that night and morning with a telescope available for visitors who want to see the Beaver Moon eclipse.

And for those interested in astronomy, keep in mind that State Parks offer a variety of stargazing events throughout the year, with a calendar listing available here.

Some Parks also host events by local astronomy clubs, like the Mid-Hudson Astronomy Association in the Hudson Valley which has a Dec. 3 public event at Lake Taghkanic State Park and the Rockland Astronomy Club, which has an November 27 event at the Anthony Wayne Area at Harriman State Park and Dec. 8 event at Rockefeller State Park Preserve. Rockefeller State Park Preserve also hosts free monthly stargazing events, with a Rockland Astronomy Club member donating use of telescope and his expertise. The next such event is Dec. 2.

At Moreau Lake State Park in Saratoga County, a telescope will be is expected available for visitors on the night of Dec. 14 for the Geminids meteor shower, which can produce up to 120 meteors a minute. Fort Niagara State Park will also be open Dec. 13 for the meteor shower.

At Clay Pit Ponds State Park Preserve on Staten Island, a Winter Solstice Astronomy Night will be held Dec. 18, hosted by Professor Harold Kozak, a NASA Solar System Ambassador.

Before making a trip, always call the specific park in advance to ensure such weather-dependent events are being held as scheduled.

And for those who aren’t able get outside the coming Beaver Moon eclipse, check out a virtual online telescope event for that night. Happy viewing!

Looking at the Big Picture: Implementing Ecosystem-Based Management in Parks

Leave a comment

Ecosystem-Based Management, sometimes referred to as EBM, is a planning tool. It helps guide decisions on where to place development such as roads, buildings, trails, beaches etc., while also considering the long and short term impacts to the environment. It also looks at how development effects not just the surrounding environment, but also the upstream and downstream environment.  EBM helps remind us to take the big picture view when we do work in our State Parks.

New York State Parks’ Environmental Management Bureau has been implementing Ecosystem-Based Management (EBM) in our parks statewide since 2008.

EBM relies on citizen participation, partnerships, science-based approaches, and taking a long-term view   to provide an informed and adaptive approach to protecting our ecosystems while providing park patrons with experiences that connect them to the natural world.

There are 6 main components to EBM. These include:

  1. Place-based focus;
  2. Scientific foundations used for decision-making;
  3. Measurable management objectives to direct and evaluate performance;
  4. Adaptive management to respond to new knowledge;
  5. Recognition of interconnections within and among ecosystems; and,
  6. Involvement of stakeholders.

Taking this approach allows us to look at interacting systems, like watersheds, rather than individual components, such as a specific plant or animal or isolated water quality parameters.  NYS Parks has used this approach to help better understand, protect and manage our resources, such as swimming beaches, lake water quality, forest health, species richness, and aquatic connectivity.

In addition to helping us look at our natural environment in a more integrated way, EBM provides a means to communicate with multiple stakeholders including citizens, scientists, the private sector and government officials.

NYS Parks will continue to integrate EBM into programs andactivities through training, watershed educational materials and ecosystem research, as well as projects which demonstrate that healthy ecosystems mean healthy communities.  Look for these EBM educational panels at Sunken Meadow State Park on Long Island (pictured above)! More educational panels and kiosks showing how our parks are part of the larger landscape are in the works for parks along the St. Lawrence River and Great Lakes.  Keep an eye out for them!

Long Island’s Winter “Wing – Footed” Visitors

1 Comment

A highlight to any winter beach walk on a Long Island State Park beach is the sighting of a seal, either hauled out on sand bars during low tide or swimming off the beach at high tide.

Harbor and grey seals, and more rarely hooded, ringed, and harp seals can be seen off of Long Island from late fall through early spring.  These seals belong to the family Pinniped, meaning “feather-footed” or “wing-footed.”    They are considered true seals – meaning they have no ear flaps, their front flippers are short, and their necks are short.   Seals are excellent divers; they can hold their breath for 40 minutes, swim up to eight miles an hour, and dive up to 600 feet.  They eat a variety of fish and invertebrates including crabs and squid.  Thanks to a thick layer of fat and a dense coat seals keep warm in winter.

The best time to see large groups of seals is at low tide when they haul out of the water to rest and sleep on sand bars and rocks. When seals are hauled out at low tide they hold their head and tail up in a “banana-shaped” position.  Be sure to watch the seals from a distance since seals can be easily scared.

Harbor Seals are the most common seal that you will see.  These 4-1/2’ – 6’ seals range in color from tan to brown to light gray with irregular black spots.  They have a smallish head that looks like a Cocker Spaniel in profile.  This profile gave them the nickname “sea dog.”  Their nostrils are “V” shape when seen from the front.  Harbor seals weigh 250 lb.

Gray Seals are a large seal with gray coloration. Interestingly, adult males are dark gray with small black markings and adult females are light gray or brown with dark patches.  Males can be 8’ long and weigh 800 lb., females 7’ and weigh 400 lb.  They have a distinctive “horsehead” profile and their nostrils form a “W” when seen from the front.  Females have a slightly smaller head than males.

Hooded Seals are the largest seal that winters off of Long Island; males are 9’ long and females are 7’ long.  Males weigh 900 lb., females 670 lb.  The coat coloration of silver-grey with irregular black spots is the same in both adult males and females.  First year pups have a slate colored coat.  All female and juvenile male hooded seals have a larger head and broader muzzle than the harbor seal.  Adult males have an unusual nasal apparatus that they will inflate when they are angered or threatened.   Juvenile males do not have this nasal sac.

It is always a thrill to see harp seals and ringed seals because they are rare visitors to Long Island.

Harp Seal adults are white with a dark harp- or saddle-shaped pattern on its back and flanks.  The more common juveniles have a light coat with dark blotches.  Harp seals look similar to harbor seals in profile but they are slightly larger (both males and females are 6’ long and weigh 400 lb.) and they have a stockier body than the harbor seal.

Ringed Seals are the rarest and smallest seals found off of the New York coast in the winter; they measure between 4’-5-1/2’ long and weigh between 150-250 lb.  Generally, the coats are a gray-black color with numerous dark spots surrounded by light areas that look like rings. Juvenile ring seals have a fine silvery coat. From a distance, ringed seals have a slightly smaller head than a harbor seal and their nose is more pointed than a harbor seal.

Join us for a seal walk at either Jones Beach State Park or Montauk Point State Park. Be sure to bring your binoculars!

And please keep your dog at home.  You wouldn’t want your dog scaring the seals.

Wildlife Spotlight: Least Terns

Leave a comment

A rare denizen of NYS Parks in Long Island is the least tern. This state-threatened species is challenged by both loss of nesting habitat, as well as predation by rats, dogs, cats, and other birds.

The least tern is so named because it is the smallest member of the gull and tern family, growing to a maximum of only nine inches in body length. These beautiful birds make their homes on the Atlantic coast. In the winter, least terns migrate to the southern United States and the Mexican coast, but once it becomes warmer, they return to the beaches of Long Island to nest. Even though they are small, least terns are mighty. If an intruder crosses a nest, the tern will dive at the possible predator screeching to frighten the danger away. Least terns also make a habit to roosting with larger terns for protection.

The importance of Long Island shoreline habitat to least terns, as well as a plethora of other migratory bird species, is the main reason why some Long Island beaches are off limits to dogs. Even where pets are allowed, be conscious of how your dog might be affecting wildlife and protect the habitat of this small, but magnificent bird.

Spotting the Leopard Frog

Leave a comment

The discovery of a new species is always a big deal, especially when it’s been living right under the noses of over 8 million residents of New York City and the surrounding counties. A new species of leopard frog, still unnamed,  was first identified by Jeremy A. Fienberg of Rutgers University in 2009 on Staten Island, and DNA tests confirmed his discovery in 2012.

It’s no mystery how this mystery frog escaped our notice for so long. There are over a dozen leopard frog species that range between Canada and Central America, and until Fienberg recognized their distinctly different vocalizations, all the leopard frogs of NY were presumed to be either northern leopard frogs (Rana pipiens), or southern leopard frogs (R. sphenocephala).

New York State Parks is collaborating with the NY Natural Heritage Program on a regional study aimed at defining the range of the newly described species in comparison to the northern and southern leopard frog. The study’s objectives are to define the distribution, habitat use, and conservation status of the three species from Rhode Island through Virginia by matching calling surveys with follow-up surveys to catch, photograph, and get tissue samples from frogs. In New York, efforts are focusing on the Hudson Valley and Long Island, where State Parks contain some large wetlands that may be suitable as leopard frog habitat.

As part of this project, Natural Heritage biologists Kelly Perkins, Rich Ring, and Matt Schlesinger, and Parks biologist Jesse Jaycox, conducted surveys and habitat assessments for leopard frogs at wetlands in state parks. These surveys were conducted at Goose Pond Mountain, Tallman Mountain, Franklin D. Roosevelt, and Taconic State Parks. Despite spending long evenings in the parks at night, when frogs are most active, no leopard frogs were found. However, these wetlands are home to many other types of frogs, including Green Frogs (R. clamitans), spring peepers (Pseudacris crucifer), wood frogs (R. sylvatica), and pickerel frogs (R. Palustris).

For now, this new species remains a cryptic member of New York’s natural wildlife. Hopefully, we’ll get to know it better in the future.
