Health & Nature

Mindful Meandering

Wednesdays: April 13 through May 18, 9:30-10:30 a.m.

Members: $3; Non-members: $6. Pre-registration encouraged.

Modern life requires, and rewards, multi-tasking. However, we miss out on fully experiencing the moment when our attention is scattered. Join us on these weekly walks to reconnect with nature and yourself. Mindfulness is the practice of deliberately attending to the present and accepting it without judgment. Being in nature brings many of us into the present more easily than other settings. Walks at the Preserve will support the practice of mindfulness with our time spent in awareness and appreciation of whatever nature presents us that day.

Designed as a drop-in series: dress for the weather and wear sturdy walking shoes.

Nancy Neff is a licensed physical therapist and volunteer Naturalist at the Preserve. She practices mindfulness to enrich her own life.

Knowing Native Plants Series

We feature a seasonal series of classes called Knowing Native Plants, in which learners of all backgrounds discover both the aesthetic and scientific aspects of our native flora through presentations and field hikes around our grounds.

Knowing Native Plants classes are held on Saturdays in the Preserve Auditorium.  The fee for members is $15 and for non-members is $20.  Pre-registration is suggested.

For registration information and class descriptions, check out our Calendar of Events.

2016 Knowing Native Plants Schedule: 

Spring Ephemerals - Saturday, April 23, 1:00 – 4:00 p.m.

Spring wildflowers such as Dutchman’s breeches, bloodroot, bluebell, spring beauty, twinleaf, and several species of trillium color the forest floor for a fleeting moment this time of year. Join Naturalist Mary Anne Borge to learn why these wildflowers are called spring ephemerals, how their life cycles work, and how their seeds are dispersed. Indoor presentation/discussion followed by an outdoor tour.

Late Spring Lovelies - Saturday, May 7, 10 a.m. – 1 p.m.

A lot happens at the Preserve between the burst of spring ephemerals and the peak of flowering shrubs. Join Naturalist Mary Anne Borge to learn about the wildlife and landscape value of the later blooming spring wildflowers including woodland phlox, eastern columbine, Solomon’s seal, shooting star, wood geranium, and the beautiful yellow lady’s-slipper orchid.  Indoor presentation/discussion followed by an outdoor tour.

Flowering Shrubs - Saturday, May 21, 1 – 4 p.m.

The Mid-Atlantic region has a stunning display of spring flowering native shrubs, filling the Preserve and surrounding natural areas with color and fragrance every spring.  Join Naturalist Mary Anne Borge to learn about our native shrubs, their wildlife value and landscape beauty. We’ll pay particular attention to the azaleas, dogwoods, viburnums, and some rose family members.  Indoors presentation followed by an outdoor tour.

Focus on Ferns - Saturday, June 4, 10 a.m. – 1 p.m.

Some native plants, such as ferns, don’t flower at all. In this popular program, Ed Lignowski, Ph.D., will teach you to identify many native ferns.

Ecology & Conservation

Botanical Master Class:  The Rosaceae

Wednesday, May 25, 9:30 a.m. – 12:00 p.m.

Members:  $30; Non-members: $35

Space is limited.  Advance registration required.

The Rose Family is important to wildlife through the processes of pollination and seed dispersal.  It also includes important fruit and ornamental crops. In the Pennsylvania flora the Rose Family is made up of 28 genera (144 species) of woody and herbaceous plants.  While species identification in many Rosaceae genera is straightforward, others including the shadbushes and hawthorns provide an ongoing challenge.

We will try to understand what holds the family together as well as the characteristics that allow us to recognize individual genera and species.

Dr. Ann Rhoads is a botanist recently retired from 36 years of employment at the Morris Arboretum of the University of Pennsylvania. She co-authored The Plants of Pennsylvania, An Illustrated Manual, with Dr. Timothy A. Block.

Weed Patrol

Pollinators and Pollination Strategies

Saturday, June 25, 1:00 – 4:00  p.m.

Members:  $15; Non-members: $20

Many plants depend on the assistance of a third party, usually an animal, to help them successfully achieve pollination. How do plants entice visitors to their flowers, and then manipulate them to carry pollen to another plant of the same species?  Naturalist Mary Anne Borge will introduce you to some of the many potential pollinators of native plants,  including bees, flies, wasps, beetles and birds, and to the strategies plants have evolved to achieve successful pollination by taking advantage of these flower visitors. Indoor presentation/discussion followed by an outdoor hunt for potential pollinators.
