This list refers to the year in which WFS field meetings took place. The reports were published in various magazines issued after the meeting but not necessarily immediately afterwards. If you click on a year it will lead to a page listing the meetings which took place in that year. From there you can find a complete list of the species found at a meeting plus a copy of the original report.
These are detailed reports similar to the written reports in the magazine but with small photos of some of the plants seen at the meeting.
