Montclair’s Alonzo Bonsal Wildlife Preserve!
Alonzo F. Bonsal Wildlife Preserve
Welcome to the 20.68 acre Alonzo F. Bonsal Wildlife Preserve! The preserve is located and owned by the Township of Montclair, New Jersey and was purchased with NJ DEP Green Acres funds. The City of Clifton is located to the north, and residential development surrounds the preserve to the south, east and west. There are 9.12 acres of adjacent lands located to the north of the preserve which are controlled by the North Jersey District Water Commission for its Wanaque Reservoir Balancing Tank which provide additional habitat for wildlife. A citizens group lobbied to save the woodland from development in the 1970′s. The Bonsal Preserve was named after a local resident whose family’s contribution augmented Green Acres funding of the site.
Alonzo F. Bonsal Wildlife Preserve
The preserve consists of remnant wetlands and uplands surrounding the Third River, a major tributary of the lower Passaic River watershed. The Third River headwaters are located in Rifle Camp Park in Woodland Park.
Third River
The headwaters were impounded in 1899 to form the Great Notch Reservoir which greatly reduced the river’s flow. The Third River’s current name was derived from the fact that it lies north of two other Passaic River tributaries (1st & 2nd Rivers).
Years ago, the river was known as Pearl River due to the discovery of the Queen Pearl aka Paterson Pearl . Freshwater pearls are found in a river’s mussel population. The Paterson Pearl, a 93 grain pink pearl, was one of the first freshwater pearl to be discovered in the United States. Other pearls were found in the Third River but none matched the Paterson Pearl.
Today, the mussels are long gone and the name Pearl River has been replaced by Third River as designated by cartographers.
The preserve has been left in its natural state with the exception of an old sewer line built in the early 1900′s. The sewer is owned by the City of Clifton. In 2008, around 10 trees in the preserve and a 12 foot wide woods road was constructed near Daniels Road, a dead end street in Clifton, to access a ruptured section of the pipe. The sewer is scheduled to be removed and rerouted in the spring of 2013.
Trail
Bridge over Third River
The main entrance to the Bonsal Preserve is located in a right of way off of Riverview Drive in Montclair. After crossing the bridge over the Third River, you can continue north to Daniels Drive in Clifton or head east or west to explore the wetlands near the Third River. The trails are not blazed but due to the size of the preserve, you can’t get lost physically without soon discovering a spot you previously traveled.

Small preserves in urban settings really provide a great opportunity to take your time and enjoy nature right in your own backyard.
Fauna
The richest concentration of wildlife found in the Third River watershed is found in the Bonsal Preserve. Baltimore Orioles, Red-Eyed Vireos, Red-Winged Blackbirds, White-Tailed Deer and Raccoon have all been spotted among others. I spotted the guys in the pictures below the day I visited:
Mourning Cloak Butterfly
White Throated Sparrow
Song Sparrow
Flora
Because a good percentage of the Bonsal Preserve consists of forested floodplains, obligate wetland plants such as Skunk Cabbage may be found in abundance.

Other species include the below among others:
American Beech
Black Cherry

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!

The preserve, known locally as Montclair’s paradise, is a great place to take a walk, birdwatch and just kick back and enjoy. Click here for directions!

River Vale’s Poplar Road Wildlife Sanctuary!
Welcome to the Poplar Road Wildlife Sanctuary! The preserve has Poplar Road to the north, Lake Tappan to the east, Cherry Brook flowing to the west and the confluence of Cherry Brook and the Hackensack River to the south.
Poplar Road Nature Sanctuary with Lake Tappan Dam and confluence of Cherry Brook with Hackensack River
The sanctuary consists of 18 acres of White Pine plantation, upland, wetlands and a meadow with beautiful views of the Lake Tappan Reservoir.
Lake Tappan
The 1,255 acre Lake Tappan Reservoir (formed by impounding the Hackensack River via the Lake Tappan dam in 1966) is owned and operated by United Water.
The 18 wooded acres were part of a 44 acre tract of woods known as the River Vale Woods. The 44 acres were once part of United Water’s watershed buffer but were later sold to developers who planned to turn the 44 wooded acres into high density dwellings. On December 23, 2002, after six years of wrangling, 18 of the 44 acres were bought by the township of River Vale using grants and loans from the Municipal Open Space Trust Fund, NJ Green Acres and the Bergen County Open Space, Recreation, Farmland and Historic Preservation Trust Fund. In 2010, 11 wooded acres off of Stanley Place near the sanctuary were preserved and will be part of the 18 acres of thePreserve bringing the total acreage to 29. An additional 5 acres (which contain a section of Cherry Brook) were purchased by the Township earlier in 2010. The remaining 10 acres, which are located across the street from the Poplar Road Nature Sanctuary were clear cut for a townhouse development in the summer of 2010.
Trails
Poplar Road Sanctuary Trailmap
After parking, proceed through the gate of the Poplar Road Nature Sanctuary towards the kiosk which is stored with informational brochures during the warmer months provided by Bergen SWAN.
Kiosk in White Pine Plantation
From the kiosk, head west through a White Pine plantation which is in the final stages of succession. As time progresses and more of the White Pines succumb to storms and other natural conditions, hardwood forest trees such as Sugar Maple will take the White Pine tree place.
White Pine Plantation
Follow the trail south to the Cherry Brook floodplain. Information signage regarding Sugar Maple and Tulip Tree may be found on the right of the trail near a chain link fence which separates the sanctuary from United Water watershed land. Turn left after skirting a brief wetland area and head east towards Lake Tappan. This section of the trail divides the White Pine plantation from the established hardwood forest.
Trail
Straight ahead is a meadow and views of Lake Tappan.
Poplar Nature Sanctuary Meadow
The meadow is a managed grassland that is periodically mowed to prevent it from becoming a forest via succession. Leaving the meadow, head north via a United Water service road and then take a left heading west back through the White Pine plantation to the kiosk to complete the hike.
Flora that may be found in the sanctuary include:
- Red Maple
