Lingering Ash Information

Introduction

As many are aware the Ash trees of North America have been devastated by the Emerald Ash Borer (EAB), an invasive beetle. What some people are not aware is an effort to help save the Ash. Research has shown that some trees seem to be more resistant to the EAB and these have been referenced as "Lingering Ash". While resistant, they still tend to eventually succumb to the EAB, but they put up a better fight. 

Researchers are working on taking these Lingering Ash which may be spread far apart and bringing them closer together to breed. Since it isn't practical to move large trees in any number, they take cuttings (scions) from the Lingering Ash and graft them into trees in proximity of one another. Then taking the a second generation of grafted trees, they find that from each generation there are trees where the resistance is greater. The hope then is that this process will produce trees that are able to defend themselves from EAB without chemical treatment and without creating hybrids with non-native trees. 

A key part of this work is to identify the lingering ash. This is where citizen scientists enter the picture. There are various research groups involved in this. One of them, Ecological Research Institute (ERI) is leading several projects where the community can gather and share information that would be helpful. Collectively, these projects are referred to as Monitoring and Managing Ash (MaMA).

Rather than try to explain everything here, let me point to some material that would be helpful.

• The Anecdata Tool - This is the website for "Anecdata" which is a platform used to collect data for various community projects like MaMA. On it you'll see 100s of various projects. You'll need to create an account and then select projects. If you do a search on "MaMA", you'll see the four related projects listed.
