Treasures In Your Backyard: Celebrating Harding Township’s Natural and Historical Riches

The Great Swamp Watershed Association (GSWA) is combining efforts with Kemmerer Library Harding Township (KLHT) throughout the month of April to highlight the Township’s natural and historical treasures.  Several programs for children and adults are planned to educate members of the public about Harding’s unique environment and its rich history. Township residents will also have an unprecedented opportunity to participate in a discounted well water testing program.

April’s activities get an early start on March 30 when the Harding Township Treasure Hunt begins. Don your fedora, summon your inner gumshoe, and then head to KLHT between 4PM and 5PM to pick up your special Harding Township treasure hunter’s kit. All participants will have two weeks to scour the landscape in search of answers to several town-specific brainteasers. Budding sleuths can solve these mysteries at their own pace, but the ultimate goal of the hunt is to learn more about the environment, history, and culture of Harding Township.

“We hope this fun adventure will engage families in discovering our Township’s rich history and environmental riches,” says Lotte Newlin, Director of KLHT.

The Harding Township Treasure Hunt will conclude on Friday, April 11, with a special prize award event at KLHT starting at 4PM. All scavenger hunt participants are encouraged to attend and share results.

One week after the treasure hunt, on Saturday, April 19, KLHT and GSWA will hold two workshops about native plants and native wildlife in Harding Township. One workshop will be geared toward adult participation and the other will be for children and their parents. From 10AM to noon at KLHT, GSWA’s Director of Education and Outreach Hazel England will present Wildlife “Berried” Treasures, a program that teaches adults how to use native plants to attract beneficial wildlife into their back yards. Participants will leave the workshop armed with a trove of information about what they need to plant in order to support local bird, bee, and butterfly populations. From noon to approximately 2PM, KLHT and GSWA will offer a special hands-on bird and bee box building workshop for children and their parents. Each child/parent team will create their very own bird or bee box that they can take home and use at the end of the event.

On April 26, from 9AM to noon, local volunteers are needed to assist with a special clean-up of all the natural treasures at Harding Township’s Bayne Park. Under the direction of GSWA’s Director of Water Quality Programs Laura Kelm, participants will tend shrubs and native grasses that were planted around the perimeter Bayne Pond in 2011 in an effort to reduce pollution from stormwater runoff. Following the clean-up activities all volunteers are invited to attend a free luncheon across the street at KLHT.

As all of these special events progress, KLHT and GSWA plan to spotlight another one of Harding Township’s most important natural treasures—its precious water supply. Unlike many other New Jersey municipalities, Harding Township relies on private wells for its water. For many years, residents have taken advantage of a free well water test for E. coli bacteria offered by the local health department. This year, and only during the month of April, residents will be able purchase an expanded water test offered through GSWA at a discounted rate. The GSWA test not only detects the presence or absence of E. coli, it also measures the level of several other important indicators of water purity, including nitrates, pH (acidity), iron, arsenic, and lead. 

Harding Township homeowners who are interested in taking advantage of the new well testing program may register with KLHT or GSWA between March 30 and April 22. All participants will be required to make a $10 deposit and pick up a self-guided water sampling kit when they register. Participants must use the supplied kit to sample well water at their home on the morning of Wednesday, April 23. All samples must be returned to KLHT between 8AM and noon the same day. (Note: Water samples that do not follow specific timetable instructions may not return reliable test results.) Homeowners may customize their well test by choosing specific testing parameters from a prepared list at time of registration. The cost for a basic, multi-parameter test will not exceed $110. Test add-ons may be purchased for an additional charge.

GSWA will collect all water samples from KLHT on April 23 and send them to Garden State Laboratories, Inc. in Hillside, NJ, for testing. Following the testing period, GSWA will mail final results to individual homeowners.

“We hope this initiative will enable Harding homeowners to learn valuable insights about the quality of their drinking water,” says Hazel England, director of education and outreach at GSWA

Did You Know: What Brings Fall Colors to Our Trees?

by Ann Campbell, Jim Northrop, & Steve Reynolds

Fall colors on display at Bayne Park in Harding Township, NJ.
Like most other plants, trees rely on a biological process called photosynthesis to manufacture the nutrients they need to survive. Photosynthesis works by using light from the sun to convert carbon dioxide and water into the food compounds—sugars and other carbohydrates—necessary for growth and renewal. Since most of a tree’s photosynthesis takes place in the leaves, it is little wonder that those beautiful, ornately-veined structures have evolved to expose as much surface area as possible to incoming sunlight.

But what is it within each leaf that interacts with sunlight? And what is it we see in autumn when leaves turn from green to red or gold, purple or orange? The answer is pigment.

Trees leaves contain several pigments. All of them are important to the function of photosynthesis, but each one plays a slightly different role. Most of us already know about chlorophyll. It’s the green stuff found in plant cell bodies known as chloroplasts. Chlorophyll does all the heavy lifting of photosynthesis, and it’s the reason why leaves appear green to us for much of the year.

Yellow and brown shades from
carotenoid pigment dominate in these
fall maple leaves.
Less familiar may be the yellow, orange, and brown carotenoid pigments that leaves possess. Like chlorophyll, carotenoids are found inside the chloroplasts, and they absorb sunlight. But instead of using that light energy to produce food, they usually just pass it along to other part of the leaf. Carotenoids are very good at preventing damage from solar radiation. So, in a sense, they behave a lot like sunscreen for chlorophyll, which is a somewhat unstable compound and easily damaged by exposure to too much light.

Red, purple, and blue pigments known as anthrocyanins also feature in the composition of leaf tissue, although they accumulate outside of the chloroplasts in the sap. These compounds excel at absorbing high-energy light waves, especially those found in the blue-green and ultraviolet portions of the spectrum. This means that anthrocyanins are even better than the carotenoids at being “leaf sunscreen." It also means that they are found in greatest quantity when days are sunny and long.

All three pigments—chlorophyll, carotenoids, and anthrocyanins—are present inside of a leaf at any given time. Most trees would be hard pressed to survive, let alone mature and grow, if they entirely lacked any one of them. Still, this seems contrary to the human experience of autumn when the passing of one season into another is marked by a change in foliage color.

The truth is that autumn’s fireworks display—as well as the other, subtler color shifts one sees in leaves—has everything to do with how much of each pigments is present at any one moment. For instance, in early spring when new leaves are unfurling, concentrations of chlorophyll are still ramping up, while the carotenoids are already hard at work hard protecting tender new tissue from the sun. The result is a leaf that is lighter green, even yellowish, in hue.

As spring gives way summer, lush greens prevail in the forest. This is when trees are working overtime to produce and replace chlorophyll at an almost-alarming rate. They are so committed to overproducing the green stuff that all of the other colors gifted by carotenoids and anthrocyanins completely disappear. This is an important point to note. Those deep emerald hues of high summer not only reflect a tree’s need to synthesize food for growth and maturation, they also indicate a steady build-up and conservation of energy aimed at shepherding the rest of the tree through the harsh temperatures and low-light conditions of the impending winter. After all, there will be no leaves to create food in just a few short months.

Colors from anthrocyanin pigments predominate in these
leaves found along the Passaic River.
As autumn dances in, it is the duration of daylight—rather than falling temperatures—that prompts a tree to change its outfit. Even so, rainfall and thermal variations affect the variety of colors it will choose to show. Because carotenoids are always present, you can count on yellows, golds, and browns in fall forest foliage just about every year. But those gorgeous red and purple anthrocyanins will only erupt when sugar levels in leaf sap are quite high. For that to happen, most of the growing season will need to have supplied lots of sunny days and plenty of moisture.

A lot of environmental variables and a lot of chemistry go into producing the annual parade of color everyone has come to expect from our forests. That said, all bets are off if Mother Nature pitches a curve ball like an early frost or a few strong autumn storms. Heavy rains or unseasonable snow will knock senescent leaves from their branches. Freezing temperatures will stop the production of vibrant anthrocyanins dead in its tracks. Droughts too can stress trees, which, in turn, may prompt the shedding of leaves before any color develops at all.

What is the lesson then? Autumn passes quickly and it may not be so glorious next year. Enjoy the fall you have right now, and enjoy it while you can!

Did You Know? The Cicadas Are Here!

by Jim Northrop

Most insects follow an annual cycle of birth, life and then death.  Seasonal changes in temperature often cue these insect life stages. However, a very noticeable exception to that rule is presently occurring.
Cicadas have emerged en masse, after 17 years in the ground. They are clambering into trees and singing a distinctive chorus that can be heard for miles because of their numerous voices. While there are many kinds of cicadas, these 17-year cicadas are a specific genus of cicada, called Periodical Cicadas (genus: Magicicada).
What makes this event so remarkable is that it results from 17 years of preparation. The now emerging army of Periodical Cicadas was born in 1996. Their mothers laid their eggs in the branches of trees. There they developed for a few weeks before hatching and heading for the ground. These larvae then squirmed into the dirt and spent the next 17 years sucking fluid from tree and plant roots.
Millions of cicada nymphs have now climbed from the ground in which they have spent nearly two decades. They will have morphed from wingless to winged creatures, and taken to the trees for their famously noisy courtship. The empty husks of the nymph-stage bugs are seemingly everywhere. Now, the newly emerged animals single-mindedly seek to mate and produce the next generation. And shortly after mating and after the eggs are laid, the adults will die. Surprisingly, cicadas barely eat a thing during their time above ground.
Their time in the sun is short, but their 17-year life span makes them the longest-lived insects known.
Cicadas will not emerge in everyone's back yard.  If there are no deciduous trees—trees that lose their leaves each fall, like maples, oaks and fruit trees—probably no cicadas will be seen. Pesticides, construction, extreme weather conditions, and tree removal are also factors reducing the incidence of cicadas. The overall emergence time for cicadas in a particular location typically is 4 to 6 weeks from the time the first nymph crawls from the ground, until the last adult dies.
Cicadas use a defensive strategy we could call "predator saturation." They reproduce by the millions in order to "fill up" the predators. The idea is that all the squirrels, birds, possums, snakes, lizards, raccoons and other predatory animals will become so full of cicadas that they tire of eating them. Then, just enough cicadas will escape and get to mate and reproduce.
Periodic Cicadas don't bother to escape when confronted, and that is because they do not have to escape. Since they emerge in such HUGE numbers, some members of their species are bound to survive no matter what. They can devote their limited energy and time above ground to calling and mating, rather than running away from each and every possible predator. This strategy may explain how an insect that neither bites nor stings, has managed to thrive.
Are cicadas locusts? No, true locusts belong in the same family of insects as grasshoppers. The confusion stems from the fact that both locusts and cicadas emerge in periodic swarms. But, locusts are far more destructive, destroying all plant life in their path. Cicadas do fly around trees and kill a few weakling branches here and there. They DO NOT kill flowers and would not damage shrubs and trees, unless the latter are young and immature. Cicadas do not damage tree leaves by chewing them as other insects do. Unlike grasshoppers and caterpillars, cicadas do not eat garden vegetables. They lack mouth parts that would enable them to chew.
Probably it is not a good idea to combat cicadas with pesticides. New cicadas will continually fly onto your trees from neighboring yards, making pesticides futile. Also, your pets could become poisoned from ingesting too many treated cicadas. Importantly, you will want to avoid the unintended collateral damage of killing honey bees and butterflies by using pesticides to disable cicadas. 
While cicadas in your back yard are a bit of a nuisance, remember that you are not going to see Periodic Cicadas again until the year 2030.

Photo Contest Focuses In On Preservation Success Story in Great Swamp

Great Swamp Watershed Association will host first public event at 113-acre Primrose Farm on June 8.

Great Swamp Watershed Association board members and
staff hike Harding's newly preserved Primrose Farm
property, January 2013.
Morris County boasts a brand new destination for those who love the outdoors.

Primrose Farm, a 113-acre tract of wetlands, fields, and forest in Harding Township, was once slated to become a 13-lot residential subdivision.  After years of advocacy work by a coalition of non-profit and community partners, and the application of more than $9 million in municipal, county, and state funding, the property was successfully preserved as open space in December 2012. Now, under the auspices of its current owners at Harding Land Trust, the site will remain wild—providing vital habitat for endangered species like the Indiana bat, and a large area of porous land capable of recharging local groundwater supplies and the nearby Passaic River.

Primrose Farm is also open to the public for hiking, horseback riding, cross-country skiing, and other outdoor recreational activities.

The first organized public use of the site will take place on June 8, 2013, when the Great Swamp Watershed Association holds The Essence of Primrose, a special photo contest aimed at capturing the quintessential spirit of the newly preserved property.

Photographers of all ages and skill levels are invited to visit Primrose Farm any time between 10:00 a.m. June 8, and 10:00 a.m. June 9 in search of one photograph that they think best represents “the essence” of this diverse and beautiful landscape.  Naturalists and professional photographers will be on hand between 10:00 a.m. and 2:00 p.m. on June 8 to help contestants tour the property and provide photography tips.

Following the photography period, contestants will have 7 days to sort and process their work before submitting a single photo for contest consideration. The deadline for submission is 10 a.m. on Sunday, June 16, 2013.

A jury consisting of professional photographers, naturalists, and others selected by the Great Swamp Watershed Association will judge each work and announce winners in three different age group categories on June 25, 2013.

Winning photographers will receive a special prize from Mpix.com. Winning photographs will be professionally printed by Madison PhotoPlus (Madison, NJ), framed by The Image Maker (Mendham, NJ), and publicly exhibited for one month at Somerset County Park Commission’s Environmental Education Center in Basking Ridge.

In anticipation of June’s photo
contest, the Great Swamp
Watershed Association and
its volunteers built this public
access trail at Primrose Farm
in Harding on May 17. This
is the first official trail to appear
at the site since its preservation
in December 2012. Photo by

“I am proud to say that, back in 2008, we were the first community stakeholder to recognize the intrinsic natural value of Primrose Farm,” said Sally Rubin, executive director of the Great Swamp Watershed Association. “We were excited when Harding Land Trust, the Trust for Public Land, and other partners answered our call to preserve this special place; we were eager to contribute to its purchase and protection; and, now, we are thrilled to be the first to introduce it to the public through this special photo contest.”

The Great Swamp Watershed Association contributed $200,000 to the purchase of Primrose Farm through New Jersey’s Green Acres program, and recently engaged a group of volunteers to build the first access trail onto the property (see photo). The organization will continue to assist the Harding Land Trust with future maintenance projects.

Groups contributing to the initial Primrose Farm preservation effort included the Great Swamp Watershed Association, the Harding Land Trust, the Trust for Public Land, the Harding Open Space Trust, the Morris County Open Space Trust Fund, and the Morris County Municipal Utilities Association.

For more information about the photo contest (including a complete schedule of events, rules, and photo submission guidelines) please visit GreatSwamp.org online or call 973-538-3500 x22. To be eligible to compete, all photographers must check in with the Great Swamp Watershed Association at Primrose Farm—located at approximately 15 Brook Drive, South, Harding, NJ—between 10:00 a.m. and 2:00 p.m. on Saturday, June 8.

Pre-registration is strongly encouraged. Visit GreatSwamp.org for a registration form. Registration is free; however, voluntary donations to the Great Swamp Watershed Association are gratefully accepted.
