GRAND JUNCTION, Colo. (KKCO) – Over the past year in the Grand Valley, many trees have started to rot and die, forcing the city to remove trees from the area.
Many trees, like ash trees, decayed and died from an invasion of pests.
Two of the three parasites are from Colorado. The lilac emerald ash borer and the bettle ash are species native to the state, wreaking havoc among ash trees.
The other common pest known in the country is the emerald ash borer, an invasive species native to northeastern Africa.
The city is seeking to remove 300 ash trees which have decayed due to an invasion of pests.
Helping to control pests in the Grand Valley attacking trees, the city started spraying some of the trees. But, unfortunately, the spray only lasts for a year and will have to be reprocessed on an annual basis.
A new method that is supposed to last around 2 to 3 years is called tree injection. They will inject a tree with a particular chemical to help fight off the pests.
They focused on injecting trees into larger diameter trees throughout the Great Valley.
âWe are trying to develop a program where residents of the City of Grand Junction could work with the city for an annual tree treatment program,â said Rob Davis, Grand Junction City forester.
For current and new homeowners who want to buy trees, Davis says you should have a mix of trees rather than the same species.
The tree mix prevents pests from jumping from tree to tree, as some pests attack specific tree species.
Davis also mentions that you should water all of your vegetation evenly. So, for example, if you water your lawn, be sure to water your trees as well.
Even watering can help prevent drought build-up in gardens; parasites can also be attractive.
