"Big tree" is a common, informal term used to describe exceptionally large trees, often referring specifically to giant sequoias. While technically any very large tree could be called a "big tree," the term is strongly associated with the massive sequoiadendron giganteum. It's a simple, direct way to express the tree's imposing size. Think of it as the everyday language for describing these natural wonders. It contrasts with the more technical botanical names.
