Fall Is The Time To Take Stock Of, And Protect, Your Trees In Denver

Fall is the time to take stock of, and protect, your trees in Denver

  • September 21, 2016

(DENVER POST) — Autumn foliage may be a sign of summer’s end, but Denver Parks & Recreation is using the explosion of color as a way to motivate people to care for the long-term health of their trees — especially their ash trees.

Denver’s ash trees provide a colorful contrast to the subdued hues of the surrounding species, with white ash leaves turning a reddish-purple in the fall. Denver’s soil pH does not typically support trees with leaves that turn that color, which is why certain developers and city planners chose to plant large numbers of soil-tolerant ash in areas like Lowry, City Park and Wallace Park. And now those trees are being threatened by emerald ash borer.

3 Years Later, Boulder Showing Clear Signs Of Emerald Ash Borer Infestation

BOULDER — The idyllic vision of a college campus is one marked and shaded by mature, historic trees – many of which are as old as the school itself. High school juniors who toured the University of Colorado’s Williams Village in 2014 saw a campus that met that criteria.

Those same students moved in surrounded by a markedly different landscape in Williams Village this fall.

Once lined by a grove of mature, 30-foot-tall ash trees, the west side of the village along 30th Street is now tree-less. The emerald ash borer (EAB) is to blame.

Just three years after the invasive pest was discovered in Boulder, the city is now starting to see the clear impact, losing hundreds of untreated ash trees to the infestation.

DENVER — When you hear stories of how harmful, invasive pests are transferred from Point A to Point B, the movement is often attributed to the irresponsible actions of an unwitting human. But the truth is usually far less black and white — at least that’s what Sara Davis, program manager with Denver’s Office of the City Forester, realized earlier this year.

Davis is one of the leaders of the Be A Smart Ash campaign, which aims to prepare Denver and educate residents ahead of the inevitable arrival of the emerald ash borer (EAB), an invasive pest that has wiped out ash tree populations in 26 states as well as in Canada.

If emerald ash borer is found, window to treat Denver ash trees is limited

DENVER (Your City Now) — Denver City Forester Rob Davis spoke with Denver 8 TV on the value of ash trees in the Mile High City, and the impact the emerald ash borer (EAB) could have on them. “Once EAB shows up in a city, usually it’s a 10-year period before all the ash trees that are not protected will die,” Davis said. “But trees that are protected will live — as long as somebody treats them.”
