Considering the evidence for abundance of Lemmus here the lack of correlation of catch with obvious abundance leaves some doubt as to the validity of the index. Transect 1 was screwed up with extra stakes stakes missing and/or out of line. Situ- normal. June 12 The marsh where T3-Ty are located shows a fairly high degree of utilization although there are only a few Lemmus here now and there on the high edges of the polygons.
