Barry Keegan Returns

Native American crafts expert Barry Keegan will demonstrate firemaking, flint knapping and other skills to recreate the daily life of the Leni Lenape people, who lived in the Croton area at the time of Henry Hudson’s voyage. He will also display his collection of Native American and colonial artifacts along with authentic replicas of bows, arrows, axes, buckskin, fire-making tools and pottery. Rain or shine on Saturday, October 20, 11 a.m. to 5 p.m.

Here's a wonderful short film about Barry's 2011 visit, made by Arboretum board member Ken Sargeant.


Forest Bathing

Bamboo forest, Arashiyama, Kyoto, Japan
We were inspired to investigate Japanese research on forest bathing therapy after getting a call from an Arboretum visitor whose parent’s anxiety and anger markedly decrease after their walks in the Arboretum. 
While “everybody knows” that a walk in the woods decreases stress, American medicine has been slow to actually measure the benefits. Starting in 1982, however, Japanese doctors have prescribed "Shinrin-yoku" (forest bathing) to decrease the risk and impacts of psychosocial stress-related diseases, including the anxiety, depression and anger associated with dementia and Alzheimers. 
Recent experiments studied the effects of forest bathing on immune system function. The most exciting result to emerge from these studies are that walks in the woods increase both the number and activity of natural killer (NK) cells, a component of the immune system that fights cancer. In one experiment, subjects took three two-hour walks over two days and stayed overnight in a hotel in the forest. As a control, blood tests were taken before the trip on a normal workday. The same tests were repeated after the second and third walks, and then weekly for several months. Elevated NK levels persisted for up to 30 days after the experiment. Follow up studies showed a significant increase in NK activity – which persisted for seven days after a day trip to the forest.
While these experiments were small scale, the study director attributes the improvement in immune activity to breathing air containing phytoncides (wood essential oils), which are antimicrobial organic compounds emitted by trees to protect themselves from insects and rot.
While more research proceeds, these early results point to the possibility that regular walks in the woods are part of a healthy lifestyle that helps us stave off cancer and mitigate the ravages of dementia and Alzheimers.
The Arboretum’s directors are committed to replant the enormous number of trees lost and damaged during the storms of 2011, not only to restore the preserve but as an investment in the health of the human community.

Feed the Trees (& Birds)!

Feed the Birds, the local source for everything related to wild-birds, as well as unique, American-made gift items, is supporting the Arboretum through the sale of reusable shopping bags emblazoned with our logo and the words “We Support the Croton Arboretum.” Feed the Birds is selling the bags for $6.00 each and 100% of the proceeds will be donated to the Arboretum.

The bags are made of Non-Woven Polypropylene (NWPP), a fabric that is recyclable, non-toxic, non-allergenic, and machine washable. They can be purchased at Feed the Birds, 326 South Riverside Avenue, Croton-on-Hudson from 10 a.m. to 6 p.m., Tuesday through Saturday and 10 a.m. to 3 p.m. on Sunday.

“One of the reasons we opened Feed the Birds in Croton was the area’s strong interest in nature-related activities,” said store owner Rob Armanini. “Being the local nature shop, one of the obvious things for us to do was join the Arboretum. We quickly realized they are funded entirely by donations, and the importance of those donations became even more evident when several storms caused some significant damage last fall. We wanted to help, in an on-going capacity and we’re proud to be supporting Croton's very own natural treasure."
