Happy Arbor Day!

It has been over 135 years since J. Sterling Morton founded Arbor Day. His simple idea of setting aside a special day for tree planting is now more important than ever.Arbor Day Foundation

The New York Times just published a great opinion piece by Jim Robbins, titled “Why Trees Matter.” I never know which articles non-subscribers can access, so please accept my apologies if access is restricted. Below are some excerpts, just in case.

We have underestimated the importance of trees. They are not merely pleasant sources of shade but a potentially major answer to some of our most pressing environmental problems. We take them for granted, but they are a near miracle. In a bit of natural alchemy called photosynthesis, for example, trees turn one of the seemingly most insubstantial things of all — sunlight — into food for insects, wildlife and people, and use it to create shade, beauty and wood for fuel, furniture and homes.

This paragraph on “forest bathing” is particularly appropriate for our Network:

In Japan, researchers have long studied what they call “forest bathing.” A walk in the woods, they say, reduces the level of stress chemicals in the body and increases natural killer cells in the immune system, which fight tumors and viruses. Studies in inner cities show that anxiety, depression and even crime are lower in a landscaped environment.

Below are some past TLN Blog posts about the role of trees in restorative landscapes:

More on scent and memory – Guest post by Wendy Meyer

Wendy Meyer, a recent MLA graduate of the University of Texas at Arlington left such an informative comment on the last blog post, on scent as an emotional memory trigger, that I thought it was worth printing in its entirety, especially since she provides a link to her thesis, “Persistence of Memory: Scent Gardens for Therapeutic Life Review in Communities for the Elderly.”

Aha, I finally figured out how to post a comment! I wrote my master’s thesis in landscape architecture on this subject–specifically, on using fragrant plants in gardens for elderly people to help conduct reminiscence therapy. There is a ton of new brain science being done on the links between smells, emotions and memories. It turns out that early, emotional autobiographical memories are strongly related to smells, because of the way the brain evolved. I looked at how reminiscence helps older people come to terms with their lives, historic use of scent in gardens as well as history of therapeutic gardens. I also interviewed a group of practitioners for their advice and insights on using scent for therapy in gardens. I got different perspectives from landscape architects who design therapeutic gardens, nurses/therapists who work with elderly populations and horticultural therapists who work in all kinds of settings. One of the recurring themes was the need for everyone involved to work together in creating these gardens–not just garden designers and hospital/nursing home administrators, but the therapy staff, families, patients and (not to be forgotten!) the maintenance staff. I spent two and a half years reading and could have spent lots longer (but I needed to graduate)! You can see the thesis at this link:

When I asked Wendy for permission to post this, and mentioned I might use a rose for the image, here’s what she had to say:

“Roses were probably the flower that came up the most–particularly rugosas, because the hips have a distinctive scent–but also lavender, gardenias, rosemary and lilac. People mentioned a lot of scents outside the garden as well–firs in the Northwest, sagebrush after a thunderstorm in the Southwest, crabapple blossoms in Wisconsin. I have a bunch of plant lists in the appendices–that was one of the fun parts to put together!”

Thanks so much, Wendy!
