COVID 19 UPDATE: A new training class will not be scheduled for the fall.  At this time, Tree Stewards are not sponsoring public volunteer events, but we will share information on virtual continuing education opportunities on this page.  Fortunately, beautiful trees can still be admired from windows and walks.

Thursday, June 25 at 12:00pm Webinar: What’s Eating My Trees? Insect and Fungal Pest Management in Southeastern Urban Landscapes
$10 tickets – Register Here
Tree problems can be a real headache. Join us for this great webinar as Dr. David Coyle discusses identification and control techniques for various tree problems. Learning objectives: pest identification and pest management strategies (chemical and cultural).

Wednesday, July 8, 2020 1:00-2:15pm ET USFS Urban Forest Connections Webinars Series
Rx for Hot Cities: Urban Greening and Cooling to Reduce Heat-Related Mortality in Los Angeles and Beyond
Edith de Guzman, TreePeople & Los Angeles Urban Cooling Collaborative
David Eisenman, UCLA David Geffen School of Medicine & UCLA Center for Public Health and Disasters
Larry Kalkstein, Applied Climatologists, Inc. & Los Angeles Urban Cooling Collaborative

Extreme heat and its health impacts are on the rise. Annually, extreme heat already causes more deaths in the United States than all other weather-related causes combined, with effects most pronounced in urban areas. Reducing urban heat exposure is an equity issue, as low-income communities and communities of color are more likely to live in neighborhoods with older buildings, low tree cover, more heat-retaining surfaces, and limited access to coping mechanisms such as air conditioning. In this webinar, Edith de Guzman will introduce the efforts of the Los Angeles Urban Cooling Collaborative (LAUCC) — a multi-disciplinary, national partnership of researchers and practitioners working to understand and implement urban cooling strategies in Los Angeles. Dr. David Eisenman will discuss heat-health impacts on the human body and how choices made in urban environments may prevent heat-related illness and death. Dr. Larry Kalkstein will present methods and findings of a recently-completed LAUCC modeling study revealing how various tree cover and solar reflectance “prescriptions” in L.A. could delay warming impacts and reduce heat-related mortality, temperature, humidity, and oppressive air masses that lead to increased deaths, and how this work could have relevance elsewhere.

Tuesday, July 14, 2020 5pm EST TREE Fund Webinar: Enhancing Tree Health in Water Sensitive Urban Design: Role of Mycorrhizae
Details Here
Brandon Winfrey, PhD, Monash University
The project investigated the effects of adding a mycorrhizal fungal inoculant on three plants species- two sedges and one tree – growing in stormwater biofilters. We evaluated the impacts on both plant establishment and on plant stress and pollutant removal after two durations of drought. We found that adding mycorrhizae had minimal impact on plant growth and stress tolerance of the tree species, Melaleuca ericifolia, and had a similar impact on sedge species. Interestingly, different species reacted differently to inoculant addition with regards to water quality improvement. Removal of nitrogen and phosphorus was improved with added inoculant in one of the sedge species, Ficinia nodosa, both before and after a 2-week dry period. These results show that mycorrhizal inoculants may be a promising amendment to biofiltration systems for improving water quality, but are less likely to improve plant health and tolerance to drought.

Ongoing Activities

Events are open to all unless otherwise noted — come out and volunteer with Tree Stewards or come to a public event to learn how to care for trees.

Every weekend and some Tuesdays area-wide: Save Trees and Native Habitat
Join Master Naturalists to remove invasive plants in Arlington, Alexandria, Falls Church, and Fairfax County. Visit this link for details and locations. Contact the site leader if you plan to participate. Some hours change seasonally.

Select Saturdays, May-September: Arlington Courthouse Tree Table
Tree Stewards staff an information table at the Arlington Courthouse Farmer’s Market once each month in the summer. This project is a fun way to earn volunteer hours while helping to educate the public and expand your own knowledge. New graduates most welcome — we will schedule you with an experienced Tree Steward. 2020 table dates are not yet available. Contact Carol Weldon at cweldon2@verizon.net if you are intersted in getting involved.

Every Fall and Spring: Casey Trees in DC
Casey Trees plants thousands of trees across the District of Columbia with help from volunteers. Learn their technique and help reach DC’s goal of 40 percent tree canopy by 2032. Register early: Tree planting opportunities fill very quickly, often the same day they’re announced. Members (donors) get first dibs. Breakfast and lunch are provided.
