Exploring the Scherman-Hoffman Wildlife Sanctuary!


Scherman-Hoffman Wildlife Sanctuary

Scherman-Hoffman Wildlife Sanctuary

Welcome to the Scherman-Hoffman Preserve! Owned and maintained by the NJ Audubon Society, the preserve features a nature center, hiking trails and a multitude of opportunities to view wildlife.

History

Scherman-Hoffman Wildlife Preserve Land Usage

Scherman-Hoffman Wildlife Sanctuary Land Usage

The history of the Scherman-Hoffman Sanctuary began in 1965 when the New Jersey Audubon Society (NJAS) received  a land donation of 125 acres from a Mr. & Mrs. Harry Scherman. 10 years later Frederick Hoffman of Hoffman Beverage Company donated adjacent acres of land. Upon his death in 1981, the final parcels of the preserve were bequeathed from Mr.Hoffman’s estate.

Field Loop Trail Forest

Today, the Scherman-Hoffman Preserve comprises 276 beautiful acres of meadows, floodplain forest and uplands.

Geology:

Highlands Precambrian Geology

Located in the southeastern corner of the NJ Highlands, the Scherman-Hoffman wildlife sanctuary is south of the terminal moraine of the last glacier (Wisconsin Glacier) which stopped just north of here around 10,000 years ago. As a result, soil was not scraped away by melting ice and is deeper than the soil found further north in the NJ Highlands. Rocks found here are deemed to have originated in precambrian times.

Virtual Tour

As it is currently a cold winter day, our virtual hike will take place in early fall when all is still green. Sound good? Let’s go! After parking, let’s head inside the  NJ Audubon Center and pick up a trail map. Before we begin our hike, let’s head upstairs to the Hawk observation deck to take in the views.

Leaving the nature center we find ourselves heading south towards Hardscrabble Road. Turning west, we have reached the Habitat Health Interpretive Trail.  While the Habitat Health Interpretive Trail does not have any blazes, the trail is only an estimated 0.3 miles. We won’t need to worry about getting lost!

Deer Fence

Deer Fence

Heading north on the Habitat Health Interpretive Trail a deer proof fence appears in front of us. The deer fence was first constructed in 1999 on one acre and a half to help promote forest health. In 2005, the deer fence was expanded to 15 acres and native plants were planted throughout the enclosure. The deer fence was constructed due to the presence of an over population of White-Tail Deer.  White-Tailed Deer have decimated the  forest to such an extent that the forest is no longer self-sustaining.

Japanese Barberry

Japanese Barberry

Outside the deer fence, invasive plants like Japanese Barberry (which deer do not eat) have formed monocultures preventing native plants from becoming established. The Deer Fence helps promote a healthy forest comprising of native plants which helps create a full understory. But most importantly, the deer fence enables the forest to regenerate successfully.

Whitegrass

Whitegrass

As we walk on the Habitat Health Interpretive Trail, let’s keep our eyes peeled to the ground for interpretive signage. All interpretive signs are placed near the plants they represent such as we see here with Whitegrass which is found in shady mesic (moist) forest communities.

True Solomon's Seal

True Solomon’s Seal

Here we see True Solomon’s Seal. The name Solomon’s Seal is said to be derived from scars on the leaf stalk which resemble the ancient Hebrew seal of King Solomon.

Other native plants present on the Habitat Health Interpretive Trail as we walk north include:

As we walk in a northeast direction we cross through the Red Blazed Dogwood Trail  spur which leads south back to the Hoffman nature center we were in earlier.

Field Loop Trail Vernal Pond

Field Loop Trail Vernal Pond

Turning south we’ve come to the end of the Habitat Health Interpretive Trail and the beginning of the Green Blazed Field Loop Trail. We’ve also just left the forest and entered a field. Heading east on the Field Loop Trail, we see a sign advertising a vernal pond heading south. Let’s check it out!

Vernal Pond

Vernal Pond

Vernal ponds are generally small, fishless water bodies that form in early spring usually from melting snow and are gone by summer. Woodland amphibians such as Wood Frogs and Mole Salamanders depend on vernal pools for breeding purposes. For more information on Vernal Pools check out the excellent book Vernal Pools: Natural History and Conservation.

Field

Turning back to the Field Loop Trail, our feet are thanking us as we walk on a mowed path through a meadow of Goldenrod and native grasses.

Welcome Please Close Gate

Welcome Please Close Gate

Arriving at the eastern exit of the deer fence enclosure, we find ourselves back at an intersection with the red blazed 1.3 mile dogwood trail.

Grasshopper

Continuing south on the Field Loop Trail, we leave the meadow and enter a young forest where a sign appears for the yellow blazed 0.3 mile River Trail heading to our left. Let’s take it!

Passaic River

Passaic River

The River Trail takes us near the Passaic River, the second longest river in New Jersey. This section of the Passaic River, near its headwaters, is clean and cool enough to support trout. Wood Turtles, a threatened species in New Jersey, can also be found in this section of the river. Threatened species are vulnerable because of factors such as small population size and loss of habitat.

Massive Tulip Poplar

Exploring the Wanaque River Watershed!


Pequannock River Coalition Preserving the Future

Pequannock River Coalition Preserving the Future

Welcome to the Pequannock River Coalition’s 2013 Spring Hike! The Pequannock River Coalition provides a crucial voice in protecting the watershed of the Pequannock River (one of the cleanest rivers in New Jersey and a tributary of the Passaic River) since 1995.

Ross Kushner Executive Director Pequannock River Coalition

Ross Kushner Executive Director Pequannock River Coalition

Meet Ross Kushner, the Executive Director of the Pequannock River Coalition. He’s going to lead the hike today!

Today we are going to explore four miles of the watershed of the C1 classified Wanaque River, a tributary to the Pequannock River.

PRC Spring Hike 4.14.13

PRC Spring Hike 4.14.13

Right now we are at the parking lot on Beech Road in Ringwood, NJ just east of Monksville Reservoir.

Monksville Reservoir

Monksville Reservoir

Ross begins by explaining that the Monksville Reservoir was created in 1987 by impounding the  2.8 mile Wanaque River and the .4 mile Beech Brook (a Wanaque River tributary). The land comprising Monksville Reservoir was formerly a river valley. Dead Trees (snags) still poke through the water where dry land once existed.

Mute Swan

Mute Swan

Looking out at the reservoir a large white bird has caught Ross’s attention. The bird is a Mute Swan, he explains. Mute Swans originated from Europe and are not native to the US. The Mute Swan, according to legend, is silent all its life until right before it dies where the bird sings an achingly beautiful melody known as a “Swan Song“. The real story is Mute Swans are not mute but actually make a deep grunting territorial sound.  Click here to hear a Mute Swan for yourself!

Gray Birch

Gray Birch

Standing near the reservoir Ross points to a stand of Gray Birch Trees across the water. Gray Birch is a pioneer species that is one of the first trees to grow following a disturbance and can be found growing on poor soils. Ross says we’ll see two additional species of Birch on the hike. Let’s begin!

Tree Swallow

Tree Swallow

As we walk  a Tree Swallow is seen flying erratically over the water. Tree Swallows prefer inland wetland ecosystems and are among the first in the American Swallow family to migrate back after winter. You can hear a Tree Swallow Sing by clicking here!

Red-Winged Blackbird

Red-Winged Blackbird

A second after seeing the Tree Swallow a Red-Winged Blackbird makes its presence known. Red-Winged Blackbirds are usually found in wetlands such as those found in the intact woodlands surrounding Monksville Reservoir. Click here to hear a Red-Winged Blackbird!

Beaver Lodge

Beaver Lodge

Near the northern edge of the reservoir Ross points out an active Beaver Lodge to us.  A beaver lodge is the home of the American Beaver and is created from sticks, mud and rocks. A small opening at the top of the lodge provides air.

Pileated Woodpecker Holes

Pileated Woodpecker Holes

As we walk closer to the woods we stop in front of an old Eastern Hemlock tree which has been punctured with large rectangular holes. The holes were created by a Pileated Woodpecker looking for one of their favorite foods: Carpenter Ants. Pileated Woodpeckers are North America’s largest living woodpecker and provided the model for the famous cartoon Woody Woodpecker. Their habitat is large mature forest such as the woods which surround Monksville Reservoir. Click here to hear a Pileated Woodpecker!

Tranqulity Ridge Passaic County Park System

Tranqulity Ridge Passaic County Park System

At the end of Beech Road, we find ourselves at the entrance to Tranquility Ridge County Park  (part of the Passaic County Park System).

Preserve in Natural State sign with Monks Connector Trail

The 2,100 acre Tranquility Ridge County Park is an extension of New York’s Sterling Forest found just north of where we are now.

End of Monks Connector

End of Monks Connector

Entering the park we are now near the end of the green-blazed Monk’s Connector trail which connects to nearby Monk’s Mountain (part of Long Pond Ironworks State Park) with Tranquility Ridge County Park.

Yellow Birch

Yellow Birch

Barely inside Tranquility Ridge County Park, Ross has spotted our second birch: Yellow Birch. Yellow Birch prefers to grow near streams & wetlands. The tree’s characteristic peeling bark is visible to all. The hairy looking vine growing on the Yellow Birch is Poison Ivy.

Yellow Birch Wolf Tree

Yellow Birch Wolf Tree

Ross spots a massive tree in the distance branching out in all directions and surrounded by young trees. Ross explains that trees can only grow sideways or to the top but can’t do both.  This “lone wolf” tree will eventually be crowded out by the young trees competing for sunlight.

On Hasenclever Iron Trail

On Hasenclever Iron Trail

We are now turning left on the Hasenclever Iron Trail. The creation of the six mile Hasenclever Iron Trail was first conceived in 2001 by the Friends of Long Pond Ironworks.  The Hasenclever Iron Trail follows an old Woods Road which dates from the 1760’s. The road connected Long Pond Ironworks with ironworks located in Ringwood.  The Friends of Long Pond Ironworks installed nine interpretive signs  along the trail in 2007. The installation was funded with a grant from the NJ Recreation Trails Program. We’ll be passing by historical signs #’s 4 through 1 today.

Beech Brook Tributary

Beech Brook Tributary

After we cross a tributary to Beech Brook Ross tells us that Beech Brook contains a naturally occurring population of Brook Trout. We have now entered the 6,911 acre Long Pond Iron Works State Park.

Beech Farm Information

Beech Farm Information

We have just passed an unmarked trail to our right and historical marker #4. Marker #4 tells us that the unmarked trail leads to Beech farm which has long been abandoned.

Wild Turkey Sign

Wild Turkey Sign

As we walk Ross points out dirt patches in the leaf litter on the ground. This was caused by Wild Turkeys looking for food.

Turkey Feather

Turkey Feather

A turkey feather has just been found in the litter. Given all this Turkey sign Ross takes out a device which makes a female turkey sound that hunters use to attract the male turkeys (toms). Ross used the device but the Turkeys have moved on for now and we do not see any.

Ross Kushner with Turkey Call

Ross Kushner with Turkey Call

Ross strongly recommended not to play the device during Wild Turkey hunting season. Want to hear what a Wild Turkey sounds like? Click here to hear!

Ross Kushner Squirrel Markings

Ross Kushner Squirrel Markings

Ross has stopped at another Eastern Hemlock and says this tree has been designated a “marking tree” by an Eastern Gray Squirrel. Squirrels rub the glands found under their chin on trees as a sign of territory to other squirrels in the other area.

Edward Hewitt Interpretive Signage

Edward Hewitt Interpretive Signage

We are now at historical marker #3 which describes Edward Hewitt, who was a member of the last family to own most of Ringwood State Park before it became state land. The Hewitt family also owned hunting and fishing camps which were built in the area we are now standing.

Ross Kushner discussing invasive Plants

Ross Kushner discussing invasive plants

This hike is taking place in early spring and the only plants we see blooming are invasive species like Japanese Barberry and Winged Euonymus (aka Burning Bush) both of which thrive in disturbed areas. Ross explains that invasive species are non-native species which lack natural predation to control their spread. As a result invasive plants crowd out native plants by forming a monoculture.

Limestone Interpretive Signage

Limestone Interpretive Signage

We’ve now at historical marker #2 which describes the role of limestone in iron making. Limestone was crushed and added to iron furnaces with iron ore where it acted as a fluxing agent to separate impurities from iron.

Ross Kushner Black Birch

Ross Kushner Black Birch

Ross has just found our third and final species of Birch: Black Birch. Black Birch twigs and bark have a strong scent of wintergreen when scraped. Ross is scraping away some the bark of a Black Birch to take a whiff. Wintergreen oil was derived from Black Birch for commercial purposes in the past.

Shagbark Hickory Grape Vine

Shagbark Hickory Grape Vine

Ross has stopped in front of an old Shagbark Hickory with an old Grape Vine wrapped around it.  Only mature Shagbark Hickories (such as the one we are looking at here) have actual “shagbark”. Young trees have smooth bark. The grape vine wrapped around the Shagbark Hickory is probably as old as the tree itself. Grape Vines prefers to grow where sunshine is plentiful and prefers forest edge habitat.

Rock Outcroppings

Rock Outcroppings

The rock outcroppings we are passing to our right are part of Big Beech Mountain which is one of the NJ Highlands “Baker’s Dozen”.

After a brief climb on the Hasenclever trail we pass near wetlands to our right.

Skunk Cabbage

Skunk Cabbage

The green leaves of Skunk Cabbage are starting to poke through. Skunk Cabbage is one of the first native flowering plants and generates heat to poke through ice and snow. It generally blooms in February. Skunk Cabbage earns its name due to a foul odor emitted by torn leaves.

Hasenclever Iron Trail #1 Interpretive Signage

Hasenclever Iron Trail #1 Interpretive Signage

We’ve just reached historical marker #1 on the Hasenclever Iron Trail. This is the last marker we will see today. This marker describes Long Pond Village, a long ago industrial village that supported the nearby Long Pond Ironworks.

Wanaque River

Wanaque River

We are now approaching the Wanaque River. The word “Wanaque” is Native American for “place of the Sassafras Tree”. A good portion of the length of the Wanaque River is impounded to form the Monksville and Wanaque Reservoirs.  Ross tells us that a bridge used to cross the Wanaque River to the old Long Pond Ironworks but was washed away when Hurricane Irene struck in 2011. The NYNJ Trail Conference is planning to rebuild the bridge in 2013.

Sterling Ridge Trail Blaze

Sterling Ridge Trail Blaze

We have now left the Hasenclever Iron trail and are turning north on the joint Sterling Ridge/Highlands Trail. The Blue-on-white 8.6 mile Sterling Ridge Trail leads to Sterling Forest State Park in New York if we kept going straight. Don’t worry! Ross has no plans to take us out of New Jersey today.

Highlands Trail Blaze

Highlands Trail Blaze

We are also sharing the same path with a section of the estimate 45 mile long interstate Highlands Trail.  The Highlands Trail is a project by the NYNJ Trail Conference which highlights the unique characteristics of the Highlands region. The Highlands Trail is still a work in progress.

Tributary

Tributary

We are now following a tributary of the Wanaque River.

Eastern Hemlocks

Eastern Hemlocks

We have stopped just as we enter a cool ravine. Eastern Hemlocks favor this habitat. Indeed, Eastern Hemlocks are all around us!

Ross Kushner Iron Slag

Ross Kushner Iron Slag

What is Ross holding in his hand? It’s an old piece of iron slag left over from the iron making operations that took place here over a hundred years ago.

Wanaque River

Wanaque River

We are heading briefly off the marked trail and walking towards the Wanaque River. The segment of the Wanaque River seen here is draining Greenwood Lake. What a great spot for lunch! After resting we continue to walk leaving the Wanaque River and following a tributary stream.

Tributary Stream Crossing

Tributary Stream Crossing

Crossing the tributary on rocks we pass the Yellow Blazed Jennings Hollow Trailhead to our left and are now stopped at the base of a Tulip Tree.

Tulip Poplar

Tulip Poplar

Tulip Trees grow straight and narrow with fissured bark. The tree’s leaves actually look like Tulip Flowers! It flowers in Mid-May to early June.

Woods Road

Woods Road

We are now walking northeast on an unblazed woods road. This is the same woods road we passed to our right when we first started out on the Hasenclever Iron Trail.

Patterson Mine

Patterson Mine

As we walk, we pass a deep impression in the ground to our left. The impression is a remnant of the Patterson Mine.  The Patterson Mine last saw operation at the end of the 1800’s. Ore from the Patterson Mine was sold to the local market or supplied ironworks found in the area.

Abandoned Motorcyle

Abandoned Motorcyle

Check out the abandoned motorcycle to our right! It’s pretty old but it is still standing.

Vernal Pond

Vernal Pond

Off to the left of the woods road is a vernal pond.  Vernal ponds are temporary pools of water that are free of fish and provide valuable areas for amphibians such as Wood Frogs to lay eggs. Wood Frogs are found further north than any other species of frog. Ross explains that the theory is this: water found in cells will expand to the point of explosion when frozen. Wood frogs have found a way to move water molecules outside their cells when they get frozen to prevent this from happening.

Red Velvet Mite

Red Velvet Mite

We’ve just turned right on another unmarked trail following Beech Brook to our right. Ross suddenly stops. He’s found a Red Velvet Mite!  Red Velvet Mites live in the soil and eat fungi and bacteria. Red Velvet Mites are harmless to humans and are part of the arachnid family (the same family spiders belong to).

Well, we’ve arrived back at the gate and back at our cars! What a great hike!

Monksville Reservoir Near the Parking Lot

Monksville Reservoir Near the Parking Lot

Want to check out this hike for yourself? Here are the directions to the parking lot where the hike begins!

Take exit 57 on Rt. 287 to Skyline Drive. Follow Skyline 5 miles north to Greenwood Lake Turnpike. Make a right there onto Greenwood Lake Turnpike and follow it about 4 miles to a right on Beech Road. Look for a gravel parking area at the reservoir on the left.

Check out Plant Communities of New Jersey.

NJ’s geology, topography and soil, climate, plant-plant and plant-animal relationships, and the human impact on the environment are all discussed in great detail. Twelve plant habitats are described and the authors were good enough to put in examples of where to visit!
