Emerald Ash Borer: The Ash Nightmare

By Rachel Murray

Many US cities are preparing for an Emerald Ash Borer, Agrilus planipennis (EAB) invasion. The EAB is native to northern Asia, but was discovered in Michigan and Ontario in 2002. The adult EAB has a bright outer metallic green color, with copper colored abdominal. It is roughly half an inch long, and only one eighth of inch wide. The EAB larva is milky white with bell shaped segments. Since it is discovery it has spread to over 25 states and most of eastern Canada. The invasion continues to move west. Already 70 million ash trees have been infected and there is a chance of losing a large percentage ash trees in North America. East Texas has already been affected by the EAB. There is a chance that EABs will travel to the DWF metroplex.

You can easily identify if your tree has been infected or not. When an EAB larva bores in to an ash tree, they create a winding S shape path, called galleries. These galleries become visible when the bark begins to split. If your tree is infected, callous tissue will start to form causing the bark to become weak. Another thing to look out for is D shape holes. After they become an adult, the EAB exits the tree and create the hole. You can recognize if your tree has been infected by checking for the S shaped galleries and D shape holes. A citizen can also observe if the tree has been infected by watching for  epicormic shoots.  Epicormic shoots are small shoots that grow from previously dormant branches. If you can identify these factors on your tree, it is likely it has been infected and needs to be treated.

There is multiple ways for you to prevent the invasion of EAB. Most time if an ash tree gets infected it will die in 2-3 years. At this time it would be helpful for you to remove your tree and replace it with another species.  As a citizen you can also spray/inject pesticides for your ash tree. You will have to do this annually, but most the time is will protect your trees from the EAB. To reduce the spread of EAB larvae, do not bring any firewood or ash wood into the area. Even after a tree is cut down the EAB larva can survive and continue to infect the area. Also when you do store firewood, be sure to always keep it away from existing trees, in case of any other pests.

Being observant of signs and knowing the prevention’s can help us stay protected from the emerald Ash Borer.

Big Tree Tour 2017 Thank You

Big Tree Tour 2017 Thank You

Mother nature cooperated and the predicted storms held off long enough to complete our spring Tree Tour. Over 20 people spent the day visiting some of the most notable trees in the region. Some were historic, some were really big and some were just odd! Local arborist Wes Culwell designed the tour stops and had a wealth of information on each tree visited. The day started with a stop at a giant post oak tree where Sam Houston camped while traveling through North Texas and ended with a live oak in Lake Worth that was saved from destruction when the highway was expanded. This tree is currently being cared for by a group of local patrons! Also thanks to the City of Grand Prairie for providing vans and drivers for transporting the tour participants.

Micah Pace, Preservation Tree – State of the Denton Urban Forest project

Micah Pace, Preservation Tree Services Urban Forester, spent the summer of 2016 studying the area trees, their effects on the environment, and how they impact the community around Denton, Texas. Data was collected, analyzed, and  reported to include how we understand the urban forest’s structure, function, and associated value.   The study found Denton currently has 3.5 million trees that impact not only the aesthetic value of the area, but also the economic development, home & property values, and how residents live, work and play in Denton. Press Release: Dallas, TX – (1/9//2016)


The story of the renewed effort in Citizen Forestry and the change in the organization from David Coke:

We held a Quarterly Meeting at Henrietta’s Orchid back in the fall of 2015.  We were sitting in the shade eating lunch after the meeting and Wanda was asking Camillle about how Citizen Foresters were organized and what her role was.  Wanda had recently completed the training in Grapevine and was just trying to figure out how she’d get in her volunteer time and get the needed CEUs as well as who was responsible for what.  What she heard was that things weren’t well organized and she’d have to take the lead on her own volunteer time fulfillment.  Wanda then took the lead on identifying a group to work on improving the organization of the Citizen Foresters and improving the way we worked on enhancing the urban forest while making it easier to get in our volunteer hours.  It was her doggedness and refusal to accept the way things were that caused all that to happen.  She spent a lot of time getting Volgistics up and going, getting the committee together, the organization figured out, and getting people in the identified roles.

Lauren Barker, Keep Denton Beautiful – Multiple tree programs/projects

Currently celebrating its 30th Anniversary, Keep Denton Beautiful, Inc. (KDB) has worked to established itself as one of Denton’s key resources for tree planting and community tree programs. Over the years, KDB has focused heavily on providing free tree planting resources, and educating the community about the importance of trees – not just for community beautification, but for improving Denton’s overall health and quality of life. KDB is one of the most “tree focused” Keep Texas Beautiful affiliates in the state. This is mostly due to Executive Director Lauren Barker who’s passion for trees and community forestry has lead KDB to be one of the states non-profit leaders in community forestry. Under Lauren direction KDB has accomplished the following in the past few years.

In the last 10 years alone, KDB community forestry programs have helped plant and distribute an estimated 31,000 trees throughout Denton. KDB’s longest-running tree programs, such as the Community Tree Giveaway – which gives away around 700 free trees per year to Denton residents – and the Denton Redbud Festival, Denton’s official Arbor Day celebration, demonstrate the organization’s ongoing commitment to nurturing and growing the community’s urban forest. KDB is responsible for re-certifying Denton through the Tree City USA Program, currently in its 26th year, and the community has also received the Arbor Day Growth Award for nine consecutive years.

In 2015, KDB worked to expand its role as a leader in community forestry by partnering with the City of Denton to introduce the Denton Tree Initiative, an ambitious campaign that aims to dramatically increase tree planting and tree education in the city over a period of three years. The six programs and projects that comprise the Denton Tree Initiative use the same grass-roots, volunteer-driven program model that Keep Denton Beautiful has so successfully implemented over its 30 years in the Denton community. The programs provide free trees, tree education, tree planting incentives, and other resources in exchange for a commitment from community members to do one simple thing: plant and care for a tree at home, at school, or at their place of work. In the first year and a half of the Denton Tree Initiative (fall 2015 to present), 424 new trees have been planted; programs have provided free tree education for 526 participants; and nearly 300 rebates have been issued for residents and businesses planting qualified trees. These numbers are in addition to the more than 2,000 free trees and numerous education opportunities KDB offers annually.

Most recently KDB partnered with the city forestry dept and Preservation tree to conduct an extremely in-depth iTree Eco analysis of the urban forest resource in the city. This monumental document has recently been published as “The State of the Denton Urban Forest” and will soon be available on the KDB website
