Distribution of the direction of change among the 2297 time series obtained. Those classed as stable showed no net change in population between 1970 and 2000 (0 was the midpoint of the range of possible change). Those classed as decreasing or increasing had non-zero change, and a few time series showed the species becoming extinct within the building block.
