Board Member Bio – Mark Ellison


Mark Ellison and his Family at Rocky Mountain National Park

Mark Ellison, graduate of Colorado State’s Forestry School,  got his start in urban forestry working for the forestry divisions of Longmont and Ft. Collins, Colorado.  He started working for the Wyoming State Forestry Division in 1998 and was stationed in Riverton for 10 years before moving to Minnesota to work for the Department of Natural Resources.  He returned to Wyoming in 2009 to work as a Community Resource Forester for the Wyoming State Forestry Division.  In 2014 he began working for Cheyenne Urban Forestry and recently became the City Forester.  He has been an ISA certified arborist since 1997.

Mature Accolade Elm, Mark’s favorite tree species

Mark formed Rooted in Cheyenne as a way to spur environmental stewardship in the community and build support and appreciation for trees.  His favorite tree is Accolade elm which is a fast-growing, highly adaptable Asian elm that is highly resistant to Dutch elm disease.

As a strong believer of structure pruning, he enjoys the pruning challenges this tree presents due to its rapid growth and sometimes poor form.  In his mind, there’s nothing better than spending time on a ladder using a hand saw and pruners to structure prune young trees with fellow arborists.

Mark and his wife Amy, who is a kindergarten teacher, have 3 kids and an Airedale terrier.  The family enjoys outdoor activities such as bike riding, camp fires, sledding, skiing and hanging out in the garage and the back yard.  The family enjoys life in Cheyenne and the many events and activities that are available, such as Frontier Days, Wyoming Brewers Festival, Fridays on the Plaza and the Farmer’s Market.
