When planning new green spaces, it is necessary to remember that the urban environment is very different from the natural environment where the species evolved. Which trees native or exotic should be planted in order to maximize carbon sequestration and pollutants removal? Which species can better face the temperature increase foreseen for the next decades? Discover theses answers and more with Dr. Francesco Ferrini by listening to the Science of Arboriculture podcast and then taking this accompanying CEU quiz to check your knowledge. (A, U, M, T, Bp)

A small dedicated group of researchers, tree climbers, and photographers set out to capture a singular image from the Waipoua forest: a complete unobstructed picture of a full grown forest conifer. Their efforts became the New Zealand Tree Project, compositing the final picture from thousands of individual shots, and producing a documentary video of this towering project. (A,Bp)

Falls are a constant danger for arborists working at height. Understanding the limitations and differences between fall protection, fall arrest, and fall restraint systems can be the difference in going home safe, or taking a trip to the hospital. Ed Carpenter explains in this month’s Science of Arboriculture. (A,M,T,L,Bm)

Species diversity in an urban forest is vital to surviving a disease threat. In this month’s Science of Arboriculture, we look at the efforts in Sweden to learn from painful lessons and create a cooperative template between arborists, municipalities, and universities in promoting species diversity.

The destructive potential of a medium-to-large falling branch is commonly acknowledged by arborists, but just how much force can a branch deliver to a target? John Goodfellow recaps a study for the utility industry attempting to answer that question in this month’s episode of Science of Arboriculture. (A,U,M,T,L,Bs)
