Emerald Ash Borer (continued)
Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. As of October 2018, it is now found in 35 states, and the Canadian provinces of Ontario, Quebec, New Brunswick, Nova Scotia and Manitoba. (Click on downloadable map below)
Since its discovery, EAB has:
Killed hundreds of millions of ash trees in North America.
Caused regulatory agencies and the USDA to enforce quarantines and fines to prevent potentially infested ash trees, logs or hardwood firewood from moving out of areas where EAB occurs.
Cost to, municipalities, property owners, nursery operators and forest products industries hundreds of millions of dollars. It is estimated that the Emerald Ash Borer will be here within five to ten years. Primarily the EAB is spread by infected wood being transported for the purpose of firewood. As such, many communities are enforcing quarantines which prevent the transport of firewood from other communities.
Emerald Ash Borer is close, having been confirmed in Sioux Falls. The city of Sioux Falls has cut down 2200 in the past year and tagged around 27,000 for removal. Fully one third of the trees in the city are ash trees with another third being maple. All of the other tree species together make up only the last third of trees in Sioux Falls. Because of the danger of compromised ash trees, the city of Sioux Falls has decided to fund the removal of trees along the streets. This is in part due to liability concerns as infected trees become extremely brittle and dangerous to cars and pedestrians and to those removing the trees.
Quarantine limits the movement of ash wood - e.g. logs, green wood, chips, firewood – out of this new county. This action will aid in slowing the spread of the insect across the state and help reduce the strain on resources to remove infested trees. The emerald ash borer does not fly far and is primarily spread through infected wood. This is of particular value from May through September, a time period when the adult beetles are emerging from ash and flying to infest living ash trees.
When the Emerald Ash Borer is diagnosed in our community we have three options:
1. If we have a large ash tree that is especially important to our yard we can choose to hire a certified arborist to innoculate it against the EAB.
2. Let nature take its course, diagnose and cut down the infested trees and start over. The problem with this approach is that one the disease reaches our community, (estimated time to reach us, is between 5- 10 years) removing infested trees would entail the enormous expense of taking down many trees in a short period of time as they become unsafe and unsightly. An infested tree becomes brittle and dangerous to both pedestrians and those removing the trees.
3. This option includes a proactive tree removal and planting new trees now and over a 5 to 10 year process that the expense can be absorbed over this time frame.
What trees shall we replace the Ash Trees with? (Because of genetic research has greatly improved, it is important to know which cultivar [type] you are planting. For this reason, it is best that you buy your trees from a reputable nursery.)
A. Is this tree resistant to pests, disease, drought, etc.
B. Survive in our Alkaline neutral soil (6.8)
D. Size - how tall the tree will ultimately be.
Here is a list of trees that have been recommended:
1. Thornless Honeylocust: Jay Gurney has called the Shademaster Honeylocust the ideal yard tree. No thorns or pods. No raking is necessary due to the small fine leaves. Grass grows well under it.
2. Male Ginko: Don't plant the female tree as the fruits are noxious smelling. Specify a male tree from a nursery that will guarantee it. Very hardy for us. (Zone 4) Recommended cultivars are the Autumn Gold and Magar.
3. Kentucky Coffeetree: Native to southeast South Dakota! Tolerates dry and alkaline soils. Recommended cultivars, Stately Manor, His Majesty, and Espresso. When shopping specify "pod-less" unless you want pods, Does not make good coffee!
4. Hybrid Elm: There are now hybrid elm trees (Asian cross) which are resistant to the Dutch Elm Disease, fast growing and beautiful. Recommended cultivars: Triumph, Wilson Elm, Discovery Elm, Accolade (Morton), Danada Charm (Morton Red Tip).
5. Hackberry: Native to South Dakota. Its a tough tree, adapted to our climate and loved by the birds for its tiny berries. Recommended cultivar Prairie Prince.
6. Little Leaf Linden: A beautiful yard tree with pyramidal shape and heart-shaped leaves. Pollinators favor it flowers which are very fragrant. It is also loved by Japanese Beetles. Recommended cultivars are Baileyi, Greenspire, June Bride and Norlin.
7. Ohio Buckeye: Unique leaf and nice bronze fall color. Moderate in size. Cultivars are Plant Homestead and Autumn Splendor.
8. Burr Oak: A nice tree if you don't mind acorns developing in a few years. It is the most tolerant of the oaks to our heavy clay and alkaline soil. Recommended cultivar is Dakota Sunrise.
9. American Yellowwood: A tree not often seen in our communities. It develops a 2-3 inch seed pods which is not desirable on a residential street but is long lived and has attractive foliage, flowers and winter bark.It also has a tendency to clump and might need to be trained to a single trunk,
