TREE Fund Webinars

TREE Fund webinars bring you the latest in tree research, directly from the scientists themselves.

TREE Fund’s one-hour webinars are free and offer 1.0 CEU (only for live broadcast) from the International Society of Arboriculture (ISA), the Society of American Foresters (SAF), the National Association of Landscape Professionals (NALP) and sometimes the Landscape Architecture Continuing Education System (LACES). See webinar descriptions for specifics. Space is limited and pre-registration is highly recommended; in doing so, you’ll receive a reminder email the day before the broadcast.

Many thanks to our webinar host Alabama Cooperative Extension System.


Future Webinars

Registration will open approximately one month before the program date.

Soil Assessment for Urban Trees—Part 2 Actions

Register Here

Tuesday, September 29, 2020, at 12 p.m. Central

Bryant C. Scharenbroch, PhD, Assistant Professor of Soil Science, University of Wisconsin – Stevens Point, Research Fellow of The Morton Arboretum

Urban soils are often difficult substrates for trees. Soil management for urban trees may involve taking preventative actions, corrective actions or both. This webinar will present some common urban soil problems and discuss best management practices for the actions we might take to overcome these challenges.

ISA and SAF continuing education credits are available for watching the entire live webinar. LA CES available to participants who successfully complete a short quiz following the live webinar.

Measuring multi-stemmed trees

Register Here

Tuesday, Oct. 13, 2020, at 12 p.m. Central

Yasha A. S. Magarik, DC Department of Transportation, Urban Forestry Division

Lara Roman, PhD, Research Ecologist, USDA Forest Service, Philadelphia Field Station, Northern Research Station

Diameter at Breast Height (DBH) is an enormously important metric for foresters, arborists, researchers, contractors, and the general public. With single-stemmed species, it is used to estimate timber volume, biomass, ecosystem services, and arboricultural service pricing. But trees that fork below 4.5 ft (where DBH is measured in the US) can pose some particular problems. Lara Roman (USDA FS) and Yasha Magarik (DC Department of Transportation, Urban Forestry Division) will share the results of their research on multi-stemmed and small-statured trees. Using field data collected on street trees in Philadelphia and survey responses from urban forestry practitioners, they will suggest some ways to answer the thorny question: How should we measure multi-stemmed urban trees?

ISA and SAF continuing education credits are available for watching the entire live webinar.
