Arborist Online Learning Opportunities in the Covid Era

In a recent blog, I discussed using online media for a site online site inspection involving a Torrey pine tree root conflict with adjacent asphalt paving.  That marked the first time I used an online media tool rather than being physically present at the site.  My client and I used Facetime to conduct the real time inspection.

Over the past decade, drought and climate change has taken a toll on millions of trees throughout California.  Drought weakened trees succumb to secondary invaders … Read More
