The Morton Arboretum states that over 80% of all landscape problems originate underground. With this in mind, it is safe to say that root problems become tree problems. The structure of a tree root system is comprised of large perennial roots and smaller, shorter-lived feeder roots. Perennial tree roots are woody and grow horizontally, primarily…Details
Arborists like the professionals at Evergreen Arborist Consultants are called on every day to make appraisals and to offer expert testimony in various cases. However, sometimes professional arborists need a bit more knowledge than what they use in their regular work. For example, an arborist may easily recognize that a tree has insect invasion issues but may not be completely familiar with a particular insect species. When something like this happens, it is important for a professional arborist to know where to go for information.Details
The International Society of Arboriculture offers two levels of recognition for arborists: qualification and certification. The experts at Evergreen Arborist Consultants hold certification from the ISA, one of the highest levels to which an arborist can aim.
What Is The Difference Between Certification and Qualification with the ISA?
While both qualification and certification by the ISA represent an achievement of education and experience, they are not the same distinction. An ISA-certified arborist, such as those at Evergreen Arborist Consultants, has passed stringent examinations over a broad body of knowledge. Certification also requires periodic renewal after showing that the arborist has updated his or her knowledge in the field. Certification is considered the best base for an arborist who may be confronted with a variety of situations.Details
Cutting trees and limbs can be a very hazardous job, particularly when the damage has been caused by a storm. Hurricanes, monsoons, tornados and heavy wind events can all lead to structural damage to a tree. Furthermore, wildfires can damage a tree and cause it to become unsafe.
When cutting trees down, however, there is more to consider than simply removing the damaged plant. Arborists such as the experts at Evergreen Arborist Consultants can provide information and evaluation of damaged trees for property owners, government agencies and others who have an interest in discovering the solutions to these issues.Details

Yosemite National Park—This past summer, a 21-year-old lost her life and four adults were treated at hospitals after a tree fell at Camp Towanga near Yosemite National Park. Pacific Gas & Electric Co. had recently inspected the tree in question and apparently found nothing wrong with the oak. PG&E were required to inspect due to the presence of nearby power lines. Tuolumne County sheriff’s spokesman Jim Oliver called the incident a “freak accident.”
Annais Rittenberg, 21, was in her second year as a camp counselor for Camp Towanga, a Jewish camp in Yosemite, when the tree fell on a campfire circle of which she was a part. Fortunately, no children were injured, but Rittenberg lost her life and four other adults were hurt, two of whom had to be hospitalized.Details
