JPM Myers 1976 Journal 29 GRID 3 12 July 0730 (again causing GRID 3. Strong E wind, but completely clear and ~35°F. By noon a fog rolled in from the E. I was interrupted for ~75 hr [illegible] when it appeared there was a possible trip to Meade River. Small groups of § and § melanotos were dispersed over the grid today, as well as brooding melanotos §§. Found one new melanotos nest - see apparent. GRID totals: 4hrs Polyticta stellera 4 (2 new nests) Somateria spectabilis 1 Pluvialis dominicus 4 Calidris alpina 10 C. mauri 3 C. melanotos § 18 - one flock of 7, most others in groups. C. melanotos § 18 - including one flock of 5 C. pusilla 7 Arenaria i 5 Phalaropus lobatus 1 Ph. fulicarius § 13 Ph. fulicarius § 0 Stercorarius 6 So - the last of the Ph. fulicarius have gone. Ph. fulicarius are very broody, with several still on nests. 13-14 July Sampling vegetation on transects 6 and 7 - see daily list for bird notes. I am using Patrick Webber's clarification of vegetation stands and mosaics, developed for the RBP study sites. Our sampling routine, which I probably described in last summer's notes, entails walking both diagonals of all transect units, recording what my foot is in every 8th pace. This gives us about 20 points/unit, ranging between 19 and 22. It takes ~10hrs to complete a transect, obviously long. In addition to recording the vegetation we also record microtopographic variation (the maximum vertical relief within a 2m radius), water depth, and soil moisture - if or if not saturated. Also whether or not there is any laminar cropping - 0 if none, 1 if noticeable, 2 if extensive. These will be used in an ordination of transect habitats. So far I have had trouble with only a few of the vegetation associations. See the attached [illegible] Sheet on the next page for a list. To Webber's 18 associations (1-18) I have added 3, #19, 20 and 21.
