What is Biophilia: ITHACA?

Biophilia is the human affinity for interacting with nature.  The term “biophilia,” which literally means “love of life,” was coined by social psychologist Erich Fromm and popularized by biologist E.O. Wilson.

Biophilia: ITHACA is modeled after the Biophilia: PITTSBURGH which is a “pilot chapter for a global Biophilia Network of creative minds dedicated to strengthening the bond between people and the natural world through education, discussion and action.”

Our Mission: To strengthen human connections to nature and to advocate for policies and practices that benefit the local natural environment.

Our Goals:
•    To create a supportive and inclusive network that fosters collaboration and learning about biophilia among people with diverse backgrounds and viewpoints
•    To welcome and inspire others with the concept of biophilia
•    To explore new approaches to strengthening human connections to nature and to discuss their application to our local community
•    To use our collective voice to advocate for and to assist in the implementation of policies and practices that benefit the natural environment

Free and open to all. Refreshments will be provided. This forum is sponsored by the Paleontological Research Institution, and the biophilia:ITHACA chapter is comprised of numerous individuals and organizations including Cornell Botanic Gardens.

Our mission is to strengthen human connection to nature. All are invited to attend this forum and become active with biophilia: ITHACA. Contact or for more information.

Closing the Arboretum to Protect our Trees

34 weeks 3 days ago

Pedestrians are welcome to explore the arboretum every day from dawnto dusk. Vehicle access resumes in spring.
Rhoda Maurer, director of horticulture for Cornell Botanic Gardens, explains why the F. R. Newman Arboretum is closed to traffic during the winter months:

Why is the F. R. Newman Arboretum closed to vehicles during the winter? 
Cornell Botanic Gardens and Cornell University do not plow or treat the roads in the arboretum.  We have chosen to practice environmental stewardship by not using salts to treat slippery surfaces. Road salts carry a high environmental cost, as they contaminate water supplies and burn the roots of nearby plants. Our collections are a living museum, and safekeeping them is part of our responsibility to future generations. 

Can’t you find a way to keep the roads clear that won’t damage the trees? 
Keeping the roads clear without using salts limits us to physical labor and resources not available to us.

What about winter days when there’s no snow on the roads—can’t you open the gates then? 
Seasonal closure of the Arboretum is necessary to ensure the safety of our guests.  And while some roads may seem clear of frozen precipitation, others in the shaded hills often are not.

How do you decide when to close the gates and open them again in the spring? 
Opening and closing of the Arboretum for the winter is based on current weather trends and the probability for below-freezing temperatures and precipitation patterns.  Given the complexity of changing climate and weather events, we strive to keep the Arboretum open for as much of the year as possible, while also providing for the safety of our visitors. 

The Joy of Living Christmas Trees

35 weeks 20 hours ago
Holiday tree selection and the search for the perfect one is upon us. Here are a few helpful hints to guide you on your quest:

Trees cut and hanging at the Christmas tree lot all seem acceptable. What to do?   Easy... simply pinch off a few needles, crush and smell.  The aroma should be pleasing. Next, with your hand, tap a couple branches at midpoint and observe how many needles fall. If many fall, decline the tree, as it has been cut for too long.  If a few fall, that’s OK. 

Lastly, gently bend a few branches with your hand. They should be flexible in all directions, yet firm enough to hold the decorations. Clean cut the trunk base at home and immediately submerse in water. Keep water level high as long as you keep the tree. Turn lights off at night, to conserve electricity and reduce fire hazard.

Now, instead of an acceptable tree, how about the perfect one? Purchase a living tree! Choose a species that grows naturally in your area. Here in the Northeast U.S., we favor blue spruce and fir varieties, such as Frasier and Douglas. Place on top of waterproof material, wrap root ball in decorative cloth, and water frequently.  Indoor air is much drier and will increase transpiration rates.  You will need to water often to keep the substrate moist.

Once the tree has served its decorative, indoor purpose, place it in a cold (approximately 40 degrees F), non-temperature- controlled space. Cover root ball with mulch, blankets, or similar material to protect it from drastic temperature fluctuations. 

Schedule a late winter/early spring family planting day and plant your Christmas tree. Not only do will you add another tree to the earth, you’ll enjoy its benefits for generations. Plus, each tree planted represents that season’s holiday and all its memories, forever expressed in the majestic crown of the tree YOU planted.

Volunteer Symposium Hosted by Cornell Botanic Gardens

39 weeks 1 day ago
On October 11 - 13, Cornell Botanic Gardens was the host site and co-sponsor for the Volunteer Engagement Symposium “Remarkable, Resilient and Rewarding Volunteer Engagement,” offered by the American Public Gardens Association.

The symposium was attended by over 45 professionals from the public garden field who are involved with volunteer management and supervision.  The group included six staff and one volunteer from Cornell Botanic Gardens.  Adult Education and Volunteer Coordinator Kevin Moss was instrumental in organizing the symposium with the Association.
The symposium featured a variety of speakers, with sessions on best practices, student engagement, volunteer retention, risk management, and more. The keynote address, “Land Stewardship and the Volunteer Connection”, was delivered by Andrew Zepp, Executive Director of the Finger Lakes Land Trust. Tours of the F. R. Newman Arboretum and Cascadilla Gorge, and an excursion to the Cornell Lab of Ornithology, rounded out the week.

One attending Volunteer Manager had this to say, “This gathering is so vital to us. For volunteer managers at public gardens, this is the only peer networking group that is gardens-based, which means that we have the chance to confer with colleagues sharing the same issues and learn from each other. The sessions and presentations were interesting, and our time at the Ornithological Research Center and Cascadilla Gorge were enlightening and thought provoking (and hiking back up through the gorge was breathtaking in the truest sense of the word…good exercise for mind and body).  The planning, location and conduct of the event were wonderfully orchestrated. Our thanks to all those who helped in making this a great success.”

Removing cattails requires a team effort and engages students

39 weeks 1 day ago
On Sept 17th, 23 Cornell students from EcoHouse joined Cornell Botanic Gardens staff to remove invasive cattails from Houston Pond in the F. R. Newman Arboretum. 

With the help of Plant Science professor Tom Whitlow, 10 canoes, 5 pairs of waders and sickle knives, the group removed the overgrown cattails that were crowding out other plants and changing the ecology of the ponds. This pilot project helped us understand what it would take to successfully remove cattails in the future. Sam Schultz, Ecology and Biology student, is following up with a research project that will recommend next steps and future maintenance strategies.  A local flowering sedge (Schoenoplectus tabernaemontani) is being grown at our Plant Production Facility to replace the cattails.
