Emerald Ash Borer to offer scares at Denver Halloween Parade

DENVER — The emerald ash borer will be on hand in all its horror at the inaugural Broadway Halloween Parade on Oct. 21, offering a taste of the scary reality the invasive forest pest presents Denver’s ash tree population.

Hosted by the Broadway Merchants Association and City Council Lucky District 7, the community-friendly Broadway Halloween Parade will begin at 6 p.m. in the eclectic and funky Heart of Broadway. Specifically, the parade route will stretch from West 3rd Ave. to West Alameda Ave. along South Broadway.

The parade is set to feature various spooky floats, bands and marchers, and all attendees are encouraged to join in the fun by wearing a Halloween costume. And yes, not only will there be an emerald ash borer (EAB) in attendance, the Be A Smart Ash campaign will be passing out a pair of fun trick-or-treat bags for all kids — and maybe even a few adults — in attendance.

While enjoying Denver’s fall color, take time to appreciate our ashes

DENVER — As a natural prairie, Denver wasn’t blessed with a host of native trees. That, in the humble estimation of Denver City Forester Rob Davis, is what makes ash trees worth savoring every fall.

“Colorado in general doesn’t have a lot of big shade trees that end up with a nice red or purple fall color,” Davis said. “So for me, fall is the time that I realize just how many ash trees we have in Denver.”

And that’s important for Davis, because he knows what’s coming: the emerald ash borer (EAB). The tiny green invader feasts on ash trees, and it’s now the most destructive forest pest in U.S. history, having caused billions of dollars in damage to ash tree populations in more than 25 states.

EAB was discovered in Boulder in 2013 and in Lafayette earlier this year, meaning it’s just a matter of time before it arrives in Denver and poses an immediate threat to the 1.45 million ash trees in Denver. That’s right, folks: 1 in 6 Denver trees is an ash. And the first step when it comes developing our EAB defense plan as a city is learning how to identify ash trees.

As far as fall color goes, green ashes turn a vibrant yellow. That’s great and all, however it somewhat pales in comparison to the white ash, which can change a whole host of colors from deep purple to a lighter red.

Help Denver fight EAB by mapping your favorite trees with Curio

DENVER — Your friendly City Forester has mapped each and every one of the public ash trees in Denver as part of its effort to prepare for the inevitable arrival of emerald ash borer (EAB). As the most destructive forest pest in U.S. history, EAB has decimated ash tree populations and caused billions of dollars in damage in more than 25 states and parts of Canada.

But it’s not just ash trees. The city has actually mapped all of Denver’s public trees, giving you the chance to learn more about the trees around you and the benefits they provide. You can give them all a look using the interactive map on this very website.

But that may leave you with intense FOMOOMT — Fear Of Missing Out On Mapping Trees. Not to worry. You can now join the tree mapping party in Denver thanks to an app called Curio.

Video: Planting unique trees may protect Denver from EAB

DENVER — Getting the word out about the emerald ash borer (EAB) and its potential impact on Denver’s 330,000 ash trees is a full-time job, and our friends at 9NEWS — more specifically, the producers of the show “Colorado & Company” — have been a big help.

Our very own friendly Denver City Forester Rob Davis appeared on the show recently, explaining whether EAB has been found in Denver, how many vulnerable ash trees we have in Denver and why they’re valuable, how you can identify an ash tree, the tell-tale signs of EAB, whether it makes sense to keep or replace your ash, your EAB treatment options, the city’s plan to treat Denver’s public ash trees and potential trees you can plant besides ash to help diversify and protect our urban tree canopy.

CPR: Denver proactive in battling emerald ash borer

DENVER — If Denver City Forester Rob Davis is looking to get under his family’s collective skin, all he has to do is start climbing an ash tree looking under the bark for signs of emerald ash borer (EAB).

“I drive them crazy, because I do it all the time,” Davis told Colorado Public Radio. “I’m always looking for (EAB). I’ve even climbed trees at a middle school, just thinking I’m going to find it. So sure.”

EAB is yet to be discovered in Denver, but consider its discovery in Boulder in 2013 and in Lafayette earlier this year, the Mile High City desperately wants to be prepared for what Davis called “single most destructive urban pest that Denver will ever have in its urban forest.”

From Denver’s interactive ash tree map to its efforts to guide residents about their treatment options to this very website and campaign, BeASmartAsh.org, Davis went on to explain to CPR in detail the $2.97 million, 10-year plan the city has implemented to try to cement Denver’s legacy as one of preparedness when it comes to EAB.

Emerald ash borer discovered in Lafayette, Colorado

LAFAYETTE, Colo. — Emerald ash borer (EAB) has been discovered in Lafayette, the Colorado State Forest Service (CSFS) confirmed on Wednesday. Lafayette is now the third city in Colorado facing an EAB infestation.

Not entirely unlike the mountain pine beetle, which decimated pine trees across hundreds of thousands of acres in Colorado’s high country beginning in 2008, EAB has decimated ash tree populations in more than 25 states and parts of Canada, causing billions of dollars in damage over the last 15 years.

CSFS community forestry program manager Keith Wood also confirmed Wednesday the newly found infestation in Lafayette remains within Colorado’s EAB quarantine zone. That zone includes Boulder, where EAB was discovered in 2013, and Longmont, where EAB was discovered in 2016. Lafayette is less than 13 miles from each city.

“Having a new detection in this area was not unexpected,” Wood said. “But it certainly highlights the need for Front Range communities to be planning now, before EAB arrives.”

Tree climbing arborists help raise EAB awareness

DENVER — Arborists from across Colorado gathered in Denver’s Washington Park for the 2017 International Society of Arboriculture’s Rocky Mountain Chapter Tree Climbing Competition. Here, these talented professionals showed off the skills they utilize day-to-day caring for trees around the state.

From the speed climb competition to much more technical climbs, arborists put a mix of athletics, tree knowledge and math skills on display — and 9NEWS was there to capture it all.

Illustrating their true team spirit, this year’s participants all donned Be A Smart Ash competition shirts, helping raise awareness about an issue they combat every day in their field, the emerald ash borer (EAB). Now the most destructive forest pest in U.S. history, EAB has devoured ash trees in more than 25 states and caused billions of dollars in damage.

Hey Denver, wondering if you’ve got an ash tree? We can help!

DENVER — Did you know 1 in 6 Denver trees is an ash? And did you know that each and every one of those ash trees is vulnerable to a tiny pest called the emerald ash borer (EAB)?

It’s what makes EAB the most destructive forest pest in U.S. history, and it’s why the Denver City Foresters Office launched the Be A Smart Ash campaign. One big part of that program is educating Denver residents on how to identify ash trees.

First let us draw your attention to our interactive, MyTreeKeeper map. Using data, technology and thousands of man hours from our diligent City Forester employees, the Be A Smart Ash campaign successfully mapped each ash tree in Denver to make identification as easy as possible.

Apply for a free right-of-way tree, Denver! But first, what’s a right-of-way?

DENVER — The Denver City Forester wants to give you a free tree to plant in the right-of-way adjacent to your property in an effort to bolster and diversify the tree canopy in the Mile High City.

But first, let’s define exactly what we mean when we say “right-of-way” – and how much space you need in the right-of-way adjacent to your property in order to apply for a free tree.

For starters, here’s the official definition of right-of-way:

“The right-of-way is the public land that includes the street, tree lawn and sidewalk – the width of which is established by the City of Denver. The right-of way also defines the boundary line along the street frontage of a property.”
