They are arranged in descending order by date. Many are technical papers but often directly address management implications. Older articles may have results that have been shown by subsequent research to contain incorrect conclusions, but that history is valuable and the articles generally contain lots of useful ecological observations from that time. Getting funding to support research for less economically important species (think bigleaf maple vs. Douglas fir) can be challenging so we are grateful for the efforts of these scientists to build a knowledge base of bigleaf maple.
