Unoccupied part show thick Bgrs, especially mid- way between centers activity. // Word A: some Vbr + Dpa still green, & some Asm. (bait.), & much Asm. Potentilla penn. also green, Bda patches partly green, but solid, recent, apparently not yet had used by C.L. Adjacent to Bda patches some Echelodon & Cristida. // Ad. #156 taken 9:05 a.m. in quadrant Ng (King's map); no extra factor out of (King's mark?). // Much Ephedraea grows in Word A still. 9:15 a.m., took adult #157 in L.H. // Word B, I saw 2 at after W. end, & one at E. end in evening. Decrease here. One burrow suddenly plugged here by C.L. (to shut off light?). // At a site on Word C when group joins, often seen June & July, no activity within 50 yds. now. // Nobal Dam town. Colonized 5/A on Bda areas; 10-12/A. upper from there when slope steepens & veg. mostly as folia (Ephedraea, Chev. lept.) & more Asm. None seen in area for 75 yds. receive be- hind sign. In part of area Cristida prominent in yaw downslope from Bda zone. New sign, more Asm. prominent; ground low, flatter. No digging for food or badger dug holes seen. One area town on slope, 50 yds. drain, has Dpa dominant (= more de- midied? grows in around wallows). // Lower Sanctuary town. 5 freshly badgered burrows one site. 5. slope near bottom mainly solid with dry Dpa. To 10/A. density. On N. slope, C.L. mainly on area where Dpa dominant. Then upslope Bgrt Asm dominate, then Asm dominates (Bda, Bgrt mixt). Some Stipa canata & thin Androp. steep higher yet on slope (grade 10%). // Sylvan town. Area C.L. has brown Dyp. popping red-brown & solid. Seven C.L. seen, a few at least being juicy.
