JD Myers 1976 Journal At Kasookat Meade River 21 August T13 complete. A glorious day, with me working up a flurt on from 0930 to 1900. Abounding for the tundra. Almost no wind. No mosquitoes (too late in season). And T13 was a joy, largely comprised of Carex marsh beside Pingo lake. The transect runs along the lake shore, and each parallel set of transect units straddles a recurring 50 plant gradient: [sketch] see attached list of plant annotating (opposite page) for key to plant annotateria. Transect 13 runs in a line parallel to the cliff, that is, out of the page. The shale line runs roughly down the zone just water-ward from the silicified zone, making most of the area within cuts on the right colour under water or squiddy. A3, thin stands of Antropila fulva, grows out in standing water. (Carex aquatilis - Peltomonium actiflorum (HL1) is a thin (1-2m wide) strip of slightly raised turf occurring in many but not all of the transects. Given how dry the tundra is this year HL1 is not even always saturated, and there may be a meter wide strip of bare mud waterward from the HL1 strip. In many places the transition from vegetated bog (B7) to water (A3) is merely a slow luxuriant growth of B7 - Carex aquatilis to heights up to 45cm. This typically occurs where there is no raised shelf along the lake, a shelf acting as a substrate for HL1. B7, largely saturated, in a mixture of Ranunculus pallari, Carex aquatilis, and (sometimes) Caltha palustris. Substrate is generally sross-free, although when it integrates with B5 or B6 there can be Dropanocladus. Instead of mosses it often has a scraggy red much for a bottom surface. Patchy of B5 occur within B7 on the drier side. In fact in the interface between these two Ranunculus pallari can grow out of Dropanocladus
