(9NEWS) — We’ve seen many images of the stunning fall colors coming out of the high country and other places in Colorado. Here in Denver, the transition to fall foliage has come around more slowly. But it is coming, and ash trees in City Park, Washington Park and even Wallace Park are leading the way.
(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.
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.
(NORTH DENVER TRIBUNE) — The destructive emerald ash borer (EAB) beetle has established itself in Colorado, and it’s only a matter of time before it reaches northwest Denver. According to a 2015 report released by the Colorado State Forest Service, EAB “has the potential to be the most devastating insect Colorado’s urban forests have ever seen.”
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.
(CONFLUENCE DENVER) — Ash trees took root in Denver in the 1970s and ’80s, according to Denver City Forester Rob Davis. They do well in the city’s poor soil, so they became an ideal replacement for American elm, which was devastated by Dutch elm disease. Now the emerald ash borer poses an even graver threat to Denver’s urban canopy than Dutch elm disease did decades ago.
(LONGMONT TIMES-CALL) — The emerald ash borer has been confirmed in Longmont. The EAB, which kills ash trees, was first discovered in Boulder in 2013. The EAB’s appearance in Longmont represents the first sighting in the state outside of Boulder.
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.”
DENVER — Denver’s City Forester is encouraging Denver residents to embrace their inner Smart Ash and join the Be A Smart Ash movement, a campaign launched May 2 in preparation for the inevitable arrival of the Emerald Ash Borer (EAB), a metallic-green insect that destroys ash trees.
(TELEMUNDO DENVER) — La Oficina de Silvicultura de Denver está pidiendo a las personas que viven en la ciudad que ayuden a mantener a sus fresnos frescos y saludables. La Ciudad de Denver lanzó el 4 de mayo la campaña “Estar fresco con un fresno” para motivar a los residentes a proteger el bosque urbano de Denver. Pulsa aquí para saber más
