SUMMARY:Charles Sprague Sargent and the American Landscape
DESCRIPTION:Many are aware of Charles Sprague Sargent’s role as first director of the Arnold Arboretum\, establishing it as the world-renowned institution it is today. Far fewer are familiar with how his close relationships and prolific correspondence with figures of national and international prominence in the developing fields of botany\, horticulture\, forestry\, and wilderness preservation or his leadership of seminal public sector projects such as his path-breaking survey of United States forests for the 1880 US Census shaped the American landscape far beyond the Arboretum’s walls. Docent Paul Eldrenkamp will lead a tour that explores the far-reaching influence — then and now– of the Arboretum’s first director.   \n\n\n\nAccessibility: This walk will include paved roads and woodchip and gravel paths.  \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nWeather Policy: Tours may be canceled in cases of the following weather conditions: severe wind\, snow\, ice\, thunder or lightning events; temperatures over 90 degrees; and temperatures below 20 degrees or due to other weather events at the discretion of Arboretum staff. In the case of cancelation\, you will be contacted by Arboretum staff no later than 2 hours before the start of the event. If you have questions about the status of a program\, please email or call the Visitor Center at (617) 384-5209 between 10:00am and 4:00pm.

SUMMARY:Research Spotlight: Bio-Controls for Black Swallow-Wort
DESCRIPTION:This is a members-only program. Not a member? Click here to join. \n\n\n\nBlack swallow-wort is a highly invasive vine in the U.S. and Canada\, but in Europe it grows benignly\, kept in check by a number of insect herbivores that only live in that part of the world. But what if we could bring one of those insects to New England? Could it control this highly invasive plant? Professor Lisa Tewksbury from the University of Rhode Island has released a number of Hypena opulenta moths in the Arboretum to see if it would control the black swallow-wort here\, and now it’s time to return to that part of the landscape and see if the experiment has worked. Join Professor Tewksbury for a Research Spotlight to learn about her work and see if we can find evidence of Hypena opulenta larva on the black swallow-wort plants here. \n\n\n\nAccessibility: This program involves some moderate hills and off-path terrain. \n\n\n\nAudience: This members-only program is appropriate for ages 12+. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.
