You are welcome to sign up for the whole series or for individual sessions. Please wear comfortable clothes and shoes.

Mindful Meandering

Wednesdays: Otctober 5 - 26, 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.

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.

Members:  $30; Non-members: $35

Space is limited.  Advance registration required.

The focus of this class will be dispersal mechanisms plants have evolved to overcome their typical lack of mobility.  Over the eons plants have evolved relationships with other organisms as well as dependence on inanimate forces to colonize appropriate habitat.  We will also consider situations where plant species have outlived their original dispersal partners.
