How helpful of Discover the Wild to produce a quick guide to tree buds. A perfect handy guide for Spring walks. They say this about their guide,
…. here is a quick guide to some of the commoner species of tree buds in urban/suburban areas. We will be adding more comprehensive winter twig and bud images of around 60 species to our website in the coming weeks.
They note that the images are not to scale. Even so, it’s good work. I couldn’t find the guide on their website, though it’s on their Facebook page HERE.
