Koford 274 Synomys ludovicianus Sept. 23, 1955 Wind Cave N.P., S. Dak. Xbt (5w of King's area 5) moisture difference. // Area 4 had 3 c.l. out. On bare parts much Dpa, widespread. Brown Arm in belt inside dry Baja matrix. (Baja has lost seeds long since). Isolated lumours 100+ 's of Area 4 show no current use; one at edge of Y, 10yds. into Baja, used. // Area W shows no use. 1/2 Arm & Baja grew in it, + tell Afa ; much Ephedraea, Dpa, & Am. lilitaider too. Not recent this year. // Area Y shows no current use; abandoned ? // Area Z, bottom S. extension of C'; may have few or no dogs - no sure c.l., diggings 4 none seen. Same at S. tip of C', only to N. of streamlined. Sure construction only to 50's. of road across bottom. // Much Ephedraea carinie in most c.l. areas here. Many leaves lost, + some partly eaten, per- haps by c.l. Occasional Cleome serrulata near c.l. lumours, + not cut down. // In Ward F I saw 9 out. Fewest where Dpa thickest. 5 in east 1/4 area. Scattered Arm and around area, but no fresh cutting of it seen (green, but tough ?). Checked slope - 20% as max. having lumours (SSW slope ). // At S.W part Ward C, much repair work on mds.
