But more important, they know trees that will be happy in your front yard, under overhead utility wires, next to your sidewalk, and in the darkest corner of your backyard. Take a look, then head to a nursery for the right tree for your place, and start planting.

Forestry Webinars to Watch for CE Credit

It may be sunny outside, but the light shines brightly from your home computer if you tune in to hear or participate in urban forestry webinars that are offered free. Most, if not all, are archived about a week after their live date, so you can watch and listen at your leisure and clock those Continuing Education hours on Track It Forward.

Logo of Southern Regional Extension Forestry's Webinar Series: Understanding Urban and Community Forests
The first of a year-long series by Southern Regional Extension Forestry starts at 1 p.m. today (Wednesday, March 14). The topic is Nature and Health in Communities: A Review of Best Available Science. In one webinar, our own Nora Palmatier discussed Tree Stewards: Case Study of Two Virginia Urban Tree Volunteer Programs. For more about the webinar series, which is designed for extension agents and personnel but valuable for Tree Stewards too, click here.

If you ever wondered if size matters when selecting a tree to plant, check out this most recently archived of Can simple production or propagation decisions impact landscape performance of container-grown trees? What are the returns on your investment in the size of planting stock? Will the “little dogs” catch the “big ones” in the end? In this webinar, Dr. Michael Arnold of Texas A&M University will consider the big impacts of small planting stock selection decisions. Some of the findings might surprise you.

Tree Stewards are not confused about the term “urban forestry,” but just to clear up any misunderstandings, let popular Tree Stewards lecturer Dr. Jim McGlone explain in a webinar produced for Virginia Master Naturalists and available to all at noon Thursday, March 22. Details.
