This point seems to provide seasonal drainage, as evidenced by a culvert nearby under the trail. Water stained leaves and other hydrologic indicators suggest a wetland, but no hydric soils have developed and with the exception of the sedge, the plants are upland indicators. BPJ is that the trail (<10 years old) impounds water and is directing flow into a drainage channel. across Waypoint 44 Closed Mixed Forest Sitka sitchensis (t) 20 FACU Equisetum sylvaticum (h) 10 FACU 40 40 Cornus canadensis (h) 15 FAC 0 0 Calamagrostis canadensis (h) 40 FAC 65 195 Betula papyrifera (t) 45 FACU 85 340 Athyrium distentifolium 10 FAC Equisetum arvense (h) 10 FACU 190 575 Carex canescens (h) 40 OBL 3.02 190 30 foot swath 40 0 0 Water stained leaves covered the bare ground.

Immediately at base of shoulder and a few feet before the community changes into a herbaceous wet graminoid with stream.
