  • Tree Growth Strategies: Douglas fir Budburst from the USDA Forest Service (3 minute timelapse video): "Within a tree species, there can be substantial variation in many characteristics such as the timing of spring budburst and the rate of shoot growth. This clip shows two seed sources of Douglas-fir growing on a site near Centralia, Washington."
