The image is a close-up of a tree trunk. The bark of the tree is rough and textured, with patches of white and gray lichen covering the entire surface. The lichen is spread across the trunk in a random pattern, with some areas appearing darker and others lighter. In the center of the image, there is a small patch of yellow lichen, which stands out against the gray bark. The background is blurred, but it appears to be a grassy field.
