2018 Steps to Save your Ash (Tree)

How do I know if I have an ash tree in my yard? (Click here for the following article with pictures.)

One way to determine if you indeed have an ash tree is to download the EAB/Ash Tree ID app which is available for both smartphone platforms. Find it in your app store by searching for ash tree. 

A few other resources exist to help provide this and similar information. One resource to use is Beasmartash.org which is a website created by the Denver City Forester who has been working to defend the city against the emerald ash borer.  Another is Colorado.gov/agplants/emerald-ash-borer which is the site hosted by the Colorado Department of Agriculture. 

The short and direct way to determine whether or not you have an ash tree is by answering these three questions:

1. Does my tree have branches opposite one another? 
By opposite branches, it means that branches protruding from tree limbs have a mate protruding from the exact opposite side of the same limb. The limbs of ash trees have opposite branching.

2. Does my tree have compound leaves?
Ash trees have compound leaves. A compound leaf is defined as having more than one leaflet per leaf connecting to a stem that has a bud at its base. Ash tree leaves typically have 5-9 leaflets per leaf.

3. Diamond-pattern bark
Older ash trees tend to have distinct diamond patterns in their bark. The bark of younger ash trees is relatively smooth.

If after analyzing your tree you find it to be an ash tree, please continue reading. Ash trees may be affected by a number of insects and environmental factors including cold injury, soil conditions, improper planting, and insects such as lilac ash borer and ash bark beetle. The little bugger getting the most press recently is the Emerald Ash Borer. Emerald Ash Borer (EAB) management strategies  Ash trees can battle the EAB 
for quite a period of time before showing the effects of infestation. Signs of infestation include thinning of leaves and upper branches and twigs. You may also notice that woodpeckers are hanging around your tree more since woodpeckers feed on the emerald ash borers. 

If you think your tree may be infested, it's best to contact a licensed professional. The Weld County Master Gardeners has a wealth of information and is ready and willing to share that knowledge with homeowners looking to figure out the next best steps. You can visit with them at the Frederick Market.

You can also find an International Society of Arboriculture (ISA) licensed arborist by visiting Treesaregood.org/findanarborist. It’s important to hire an arborist that is certified to provide reliable information. The State Department of Agriculture provides this list of tree care professionals. As EAB has become recognized, “arborists” who are not certified have become more prevalent, so please ask if they are certified by ISA. 
If you think you have a tree infected by EAB, call the Colorado Department of Agriculture at 1-88-248-5535 or filling out their EAB report form.

Remember, the greatest risk of long-distance spread is from the human movement of infested ash trees or firewood. Do not transport ash or any hardwood firewood, or any other untreated ash wood products, to other locations. Boulder County and some surrounding areas are under a federal EAB quarantine, allowing for significant fines for those who move untreated wood from the area.
