Plant pathologists needed!

First it was the Chestnut blight, then Dutch Elm disease, followed by the Emerald Ash Borer! Now a new enemy of trees is on the horizon. The American Beech, Fagus grandifolia, one of the most impressive trees in eastern forests, is now under attack.

 

They're working on it. Right now research is still at the stage of identifying the pathogen that causes shrivelled beech leaves mottled with black stripes. A possible cause has been tentatively indicted, a leaf-infesting nematode. But bacterial or fungal pathogens may also be involved.

Of Beetles and Oaks

Image
 The beetle pictured below is only 5-7 mm in length. It's not even as long as its scientific name. It is sometimes called a picnic beetle. But what this beetle can carry is no picnic for oak trees. This little fellow is the villain in my new article for the Toronto Field Naturalists website.

Do you live in a tree city?

Image
You can find out at treecitiesoftheworld.org! Tree Cities of The World is an organization devoted to recognizing global leaders in the development of an urban forest. It's a rather exclusive group. Only 138 communities world wide have been so recognized. But they are located in over 20 countries, from Canada to New Zealand, from Argentina to Uganda. Canada, one of the better represented nations, has 18 tree cities at the moment, including Toronto, Victoria and Guelph. How can your city become known for its respect for trees? Reporting for the Toronto Star, Laura Broadly writes, "To become a Tree City, a community must meet five core standards that illustrate a commitment to caring for its trees and forests. These standards include establishing responsibility, setting rules, knowing what you have, allocating resources and celebrating achievements."

Tree protection laboratory on guard in UK

Image
Tree health. It's something we don't often think much about do we? We're concerned about planting more trees. But what happens if those newly planted trees don’t survive? It could be from lack of water. Or it could be because of an attack by some disease or insect pest. England has just announced the establishment of the new Forest Research Holt Laboratory, designed to apply modern research tools to combat all the ills that may plague the country’s trees. The lab they say will be a part of an equally new Centre for Forest Protection. Now most countries with a forest industry will have had plant pathology labs established decades ago. In Canada for instance, research on the Spruce Budworm goes back at least to the 1950s. So maybe the UK announcement indicates not so much a novel idea as a global awakening to the importance of protecting trees everywhere on the planet. Whatever the rationale, more power to them!
