Natural forest growth is important to carbon sequestration patterns, and climate is likely to alter both disturbances and regrowth. Forest Service scientists used remote sensing and inventory data to examine recent trends in biomass and forest area in southeast Alaska. They found that while rainforest dynamics occur at a very small spatial scale (less than 1,000 square meters), the net result of thousands of individual events is regionally patterned change. Forest area gains were concentrated on northerly aspects, lower elevations, and higher latitudes, whereas loss was skewed toward southerly aspects and lower latitudes. Repeated measures on inventory plots also showed biomass increases on gentler slopes and higher latitudes. This research can help land managers understand how the temperate rainforests of Alaska are changing over time.
