Finding the more adaptable tree

Trees are living organisms. And like all living organisms, trees are totally dependent on their environment for a successful life. They need nutrient rich soils. They need sunlight for energy, carbon dioxide from the air to make new tissue for growth and oxygen at night to generate the energy for life processes. Trees need rain for the water to keep their leaves from wilting. And they depend on a wide variety of other organisms, from fungi to assist with absorbing minerals to squirrels that carry their seeds far and wide.

So it stands to reason that if the environment is getting less reliable, the trees that will survive into the future are the ones that can adapt to changing conditions. This is the premise the drives the research of Katharina Braeutigam, a researcher who studies the epigenetics of trees at the University of Toronto. What about the expression of a tree's genes can make it more adaptable? Finding out may give trees a better chance to go on doing the job we depend on, sucking carbon-dioxide out of the atmosphere to combat global warming.

Braeutigam is working primarily with the quick growing balsam poplar to find some answers.

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!
