Clearing the Invasive Mile-a-Minute Vine from the Armstrong Vernal Pool

The afternoon of July 15th, five volunteers joined PRLC’s Land Steward, Krista Munger, in undertaking a mass pulling of the invasive mile-a-minute weed at the vernal pool at the Armstrong Preserve. Volunteers ranged from a rising junior at Fox Lane High School, Luke Lyons, to Gail Jankus, Pound Ridge Conservation Board Chair. Also lending a hand was Carrie Sears from the Pound Ridge Invasive Project and a volunteer from Mile-a Minute Hudson Valley. While there are no strict requirements for volunteering on PRLC projects, volunteers who participated showed a marked affinity for nature, excitedly chattering about environmental topics and eager to demonstrate their knowledge of regional plant and animal species.

Weeding efforts focused on the Armstrong’s vernal pool, one of three ‘outdoor classrooms’ used for workshops and hands-on learning. Armstrong’s vernal pool is a highly functioning wetland ecosystem teeming with biodiversity. Volunteers set out with gloves and garbage bags as they made their way along the trail.  The invasive is a thorny vine that not only hurts when picked without caution, but more importantly, has proven to be a competitively dominant invasive species that suffocates and crowds out other plant life. If pulled and then thrown on the ground, the vine is still able to regenerate. It is clear that mile-a-minute weed threatens the delicate vernal pool ecosystem as it tries to take root and displace native plants that are part of the pool’s complex web of species and interactions which keep the fragile eDSC_0958cosystem in balance.

Making their way through the tall, thick grasses, by early afternoon, the weed had been eradicated and the vernal pool no longer sported sprawling clusters of the invasive. PRLC relies on the dedicated help of volunteers to implement preserve management plans and their stated requirements, such as the removal of invasive or harmful species. Volunteer work sessions are a great way to not only be outside and actively protect important, local, natural habitats, but also to participate in educational opportunities for understanding the importance of land stewardship, preservation, and what human intervention is needed to manage sustainable habitats.

Beautiful Spring Day at the Armstrong Open House

DSC_0736With Pound Ridge PRIDE Day in full swing downtown, several families came to the other end of town to join PRLC board members and our college summer intern, for a tour of the PRLC’s Armstrong’s working backyard landscape on a beautiful, Sunday afternoon, June 6th. The spring garden gave up over 150 strawberries that day and oIMG_20150608_135502889 (2)ver the next few, all plucked by young fingers with large smiles after the sweet flesh and juice was tasted.  It was learned that only after bees pollinate the dainty white flowers does the fruit appear. Bites of early parsley, lettuces, bok-choy leaves– all had different responses from those willing to sample. The red and purple butterfly garden was not yet in bloom although the foxglove’s tall flowery stalk  made up for it.  A dozen green, white and beige colored eggs were gathered from the hen-laying box and new understandings about composting and the importance of soil health were highlighted. Tim G.- our green energy guru -shared the component updates to our upgraded, off-the-grid energy systems that will continue to be the showcase for future energy tours for local architects, builders and homeowners. We will share the results of our monitoring systems as they produce data over the next months, comparing traditional family-household energy consumption to PRLC’s closed-loop experiment in ‘living lighter on the land’.

Fabulous Plein Air Charcoal Workshop Taught in the Armstrong Preserve's Meadow

DSC_0512On May 2nd, eight art workshop participants were treated to a fabulous plein air charcoal session taught by well-known, local artist Kendall Klingbeil who has a studio and teaching space in Scotts Corners. This 2nd annual workshop set up in the Armstrong Preserve’s meadow to capture the structures and shapes of several multi-trunked trees, stone walls, an old twisted apple tree,  and nearby vistas. The quietness of the meadow was the perfect place for one-on-one instruction for those needing a bit more assistance. For those immersed in their work, the meadow and woodland edge provided both inspiration and challenge. Materials were handed out before everyone took the short hike to seek their spot in the early spring meadow. Before heading out, Kendall facilitated an indoor exercise having everyone draw the shadows resulting from an egg to demonstrate how to use the charcoal stick most effectively. The “New York Times” describes Kendall as an “energy painter whose works make people feel good”. At the end of this plein air session, everyone had learned what was positive about their afternoon art effort!

Pleasantville Honor Society Students Help with Early Spring Clean-Up

For a second year, students from Pleasantville High School Honor Society lent a hand. Earlier this spring, with snow still on the ground, students joined Krista to earn community volunteer credit by helping with our spring clean-up of Armstrong’s working backyard landscape. They were treated to fresh eggs from Armstrong’s chickens and a taste of our first year maple syrup from our sugar bush stand. They assisted Krista with cleaning out the hoop house which already had early spring greens, turning the compost and freshening up the chicken coop and run. After mixing soil for seed starting, they dropped seeds into filled dried manure pots and moved germinated plant trays under Armstrong’s solar powered indoor lighting. They dug into freshly uncovered soil in the rear of the  mandala garden to plant early peas. Participants at our upcoming May 30th workshop in the garden, Planting for Productivity, will move the young vegetable and edible flower plants established indoors- outdoors for the new growing season. (See online calendar for more info).

Tracking in the Halle Ravine Winter Wonderland

SAM_4057A dozen hardy souls joined PRLC’s Guided Hike in Search of Winter Wildlife at the Halle Ravine on the morning of February 28, and were duly rewarded for their efforts to bundle up early and explore this beautiful nature preserve. Hikers including our Land Steward & Educator, Krista Munger, had packed a narrow foot path through deep snow up and down most of the length of the marked trail system, and animal sign was abundant.

Halle Ravine is famous for its deep stream course and the stand of Eastern hemlock surrounding it, but the Preserve is also home to a mixed hardwood stands of Sugar maple, poplar, ash, and beech, and there is an Alder swamp in the southern end. One might expect to see woodpecker sign on the trees, and feathers, as we did, from foraging winter songbirds. The most commonly seen tracks are those of deer, gray squirrel, mouse, raccoon, and red fox, but we could also find long- or short-tailed weasel, coyote, fisher, or even bobcat passing through.

As usual, it was the sharp-eyed children who made the keenest observations. One family actually found a bit of fur from the tail of a Red fox. Fox commonly use human trails, especially when the snow is deep, and this fox’s trail crisscrossed and joined ours several times. Another noted a curious site where a squirrel track ended with a disturbance to the snow cover, and no tracks leading away. He deduced that a bird of prey had taken the squirrel. Scat was observed later in a large depression in the snow protected by a hemlock. This was discovered to be a deer bed!

Gardening Series features Master Herbalist, Olga Ivanova, Sharing the Benefits of Herbal Teas

Gardening Series Herbal Tea EventOn Saturday, January 10th, over a dozen Pound Ridge and neighboring town gardeners met to hear Olga Ivanova, originally from Russia, share her talents and knowledge of growing herbs specifically selected for creative, medicinal, aromatic, therapeutic and just plan delicious, home-brewed teas. Herbs make voluptuous complements to flower or vegetable gardens and have pollinating and pest deterrent benefits when companion planted with both native and non-native ornamentals or edible crops. This indoor event during the recent cold snap, was the first in a three part winter-spring gardening series offered at the Armstrong Education Center with everyone enjoying the heat of the wood burning stove while creating their own tea mixture out of over 50 samples brought by Olga from around the world– all with varying aromas, textures and tastes. Each tea selection was related to many of the plant families we are accustom to here in the Northeast but with a twist and, as the participants learned, are suitable for backyard or growing-in-pot conditions. Olga recommends brewing home-grown herbs for tea at varying temperatures and for different times for best results. In addition, she suggests certain mixes of leaves, flower petals, bark and berries. For example, to make an English rose tea, combine red rose petals, lemon balm dried leaves, and dried rosemary, all mixed well, in a single teaspoon for each cup of brewed tea. For more of Olga’s recipes and herbal combinations for teas, healthcare and relaxation, PRLC will be inviting her back for future, hands-on workshops. Stay-tuned!

Upgrades, Systems Integration and New Green Energy Components Highlighted at the Armstrong House’s Fall Energy Tour


Veterans of past Energy and House Tours as well as new visitors had the opportunity to informally tour the green energy systems of the off-the-grid Armstrong House and Education Center with local experts. The tour  highlighted optimization of integrated energy systems for reducing residential resource consumption. Discussion centered around the Armstrong’s upgraded 7kw solar PV system  sitting cliff-side, its low-temperature radiant heating system, indoor heat recovery unit, and plans for integrating its onsite, solar thermal array into the domestic hot water and radiant space heating systems. Recent work has included upgrades with safety, maintenance and future technology integration in mind. With the 40- plus year-old well pump finally biting the dust this past spring, visitors learned about the benefits of Armstrong’s newly configured water system with its latest, variable speed well-pump technology, monitoring computer and other components lending greater efficiency to what is often one of the larger, residential energy draws. The indoor tour featured a recap for first-time visitors on the completed 5-year renovation using reclaimed, green or recycled construction materials, sustainable interior finishes, low-energy use appliances, a superefficient wood burning stove, air-exchange and ventilation systems, cell foam insulation to create that important tight building envelope and 21st century monitoring capacities to understand how residents’ behavior can increase or decrease energy consumption and water use.  Visitors look forward to PRLC’s Spring 2015 Energy Tour to be held in late April.

Bog Bridges at Carolins Grove and Installation of Deer Exclosures Are Highlights of Summer/Early Fall Volunteer Projects

DSC_1610 DSC_1588The morning of Saturday, September 20th , with new re-generation and small, robust-looking seedlings planted by PRLC in 2013 gaining ground after Hurricane Sandy wrecked havoc on Carolins Grove Preserve, volunteers and PRLC staff installed deer fencing in three important locations in the Grove. With financial assistance from Volunteer New York! and an Americorps volunteer, community residents helped to diversify new growth and protect the Grove’s wooded landscape with native perennials. Some hung fencing wire and attached plastic 8 foot fencing materials, others dug holes, planted and watered. PRLC  will continue to monitor woodland regeneration, control invasives where most important to this landscape, and bring additional diversity in the way of a variety of propagated seedlings  to strengthen the Grove’s resiliency for future years and weather impacts.

DSC_1413Earlier in the summer, volunteers helped our community’s younger hikers stay dry when visiting the Young Explorers Loop at Carolins Grove from  Pound Ridge Elementary School grounds, by constructing over 60 feet of bog bridge over seasonally muddy areas of the trail used for outdoor learning.  Volunteers carried in materials, laid cross locust boards in place- all set on pre-harvested and cut cedar logs. Several high school students earned community service credits for their work.

This Summer- Ongoing Invasive Control and Management at the Isaacson Fen, Clark and Carolins Grove Preserves

PRLC land steward and field biologist, Krista Munger, says “we manage each preserve differently according to its important habitat”. With this in mind, PRLC staff and volunteers joined conservation groups across New York State to control invasive species and restore native habitats during Invasive Species Awareness Week. July 12th as part of PRLC’s first-Saturday-of-the-month morning volunteer work sessions, staff, student volunteers, college summer interns and PR neighbors worked to preserve a rare fen habitat at PRLC’s Isaacson Preserve. Just about 50 volunteer hours were spent hand cutting and bagging the invasive phragmites reed which inundates this sensitive and rarely seen environment, home to wonderful dragonflies and grasshoppers. Participants got to understand how difficult the actual removal of this invasive plant is and reviewed PRLC’s impact on the fen’s native vegetation through investigation of study plots from years past.

DSC_1374 Invasive management was addressed by volunteer work sessions throughout the summer in PRLC’s 70-acre Clark Preserve  where swaths of invasive barberry was removed pursuant to a forest management plan and a grant from the NYS Watershed Council. In addition, a vernal pool habitat was made more conducive to wildlife with the girdling of several invasive Norway Maples and the removal of barberry and climbing vines. A private grant has been made to establish protected areas where newly planted native shrubs will be established this fall to assist with overall woodland health and resiliency.



Walking Tour of the Isaacson and Halle Preserves Reveals their Quiet Secrets

Hale RavineFive local landowners joined Krista, our land steward/educator for an insightful wetlands guided talk and tour of the mysterious and seldom visited Isaacson Preserve – one of PRLC’s 17 preserves held for wildlife and habitat protection. Krista's talk focused upon the need to view wetlands as part of larger overall systems, called watersheds, of which there are 11 in Pound Ridge.

The contiguous Isaacson and Halle Ravine Preserves are located within the Mill River North watershed, which feeds the Mill River South and eventually empties in Long Island Sound. The Isaacson Preserve encompasses a red maple swamp with open areas of grass and low shrubs which, together are called Fens.  Water flowing below and slightly above the surface provides a constant nutrient source for a rich community of specialized plants and animals.

Our small group saw Swamp azalea, seldom found anymore due to deer browse.  We were also treated to a broken wing display from a Black-and-white warbler, which had its nest on the ground nearby along the steep bank lining the wetland.

As there is no trail at the Isaacson Preserve, it is suggested that visitors contact us to gain guided access.

We will be hosting an important summer volunteer work session on July 12th doing work to restrain the impacts of the invasive phragmites on this delicate environment. Contact Krista at for more information and to register as a volunteer.

You are also invited to schedule a meeting with Krista to discuss your property’s location within one of Pound Ridge's watersheds and to target management concerns related to local wetlands’ health with best habitat management practices.
