Listening to Trees at Ellis Pond

Full of bees on a spring day, this fragrant Dogwood sounded like a dynamo humming in the sun. The location is the Lloyd Kennedy Arboretum at Ellis Pond in Yellow Springs, Ohio. Continue reading

A Living Fossil (the tree, not me)

Brendan planted a Dawn Redwood for me in the northeast corner of the garden. I need it to fill a gaping hole in the tree-line left by unfinished construction work on the other side of the fence. It should grow quickly. There is a beautiful specimen on the west bank of Ellis Pond, probably planted in the late 1970s, which is now more than 30 feet tall. And it should last a while. Metasequoia is one of the oldest living tree species. Like the Ginkgo tree, its lineage stretches back to the time of the dinosaurs. The ancestor of today’s trees, “rediscovered” in China in the 1940s, was believed to be 500 years old. Continue reading

Morning Deer Report: A Serviceberry Survives

This little Serviceberry deserves a medal for valor in the struggle of trees versus deer. I planted it in 2018 when it was a bareroot twig. In the next two years deer hoovered up the fruit buds and gnawed it to the ground. In 2021 I put a deer cage around it. This spring it blooms resplendently for the first time. Continue reading

3.04 Trillion Trees Are Not Enough

[Crowther et al 2015] Anstract: The global extent and distribution of forest trees is central to our understanding of the terrestrial biosphere. We provide the first spatially continuous map of forest tree density at a global scale. This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate. Of these trees, approximately 1.39 trillion exist in tropical and subtropical forests, with 0.74 trillion in boreal regions and 0.61 trillion in temperate regions. Biome-level trends in tree density demonstrate the importance of climate and topography in controlling local tree densities at finer scales, as well as the overwhelming effect of humans across most of the world. Based on our projected tree densities, we estimate that over 15 billion trees are cut down each year, and the global number of trees has fallen by approximately 46% since the start of human civilization.
