Bufo boreas (34)
June 4 1/2 mi. S Garst Center, Yoc. Valley.
Attein have as many as 4-5 large on each upright branch. Sky clear with some cloudiness to the W.
The day has been alternately cloudy and semi-clear.
Relative humidity readings 4:15 P.M. in open sunny
open almost dry grass DB 79; WB 62 F. Initial
reading, 81 F. Monstrose mosquitoes out this afternoon.
Wild rose has bloomed out (violet colorama) since first
vegetation check. This species acts a climber among
rhododendron bushes E and SE of my study pond. I
noted a few Dodecatheum plants in the meadow, these
blooming at to 10" height. Algal growth seems
restricted to a greenish-yellow growth matting
near the edges of the pools. It is heavier than
ever before but still covers less than 1/5 of pond
surface. Lots of water in meadow. The supply
seems unchanged over past 2 months. I made a
quite thorough check of the ponds for eggs, covering
area within 50-75 yards E and W of walk footpath.
No trout eggs. Hydran tadpoles larger and reduced
in numbers. They swim and bury themselves in
bottom mire as you approach, making it difficult
to catch them with a small gig net.
Stevenson meadow, Yoc. Valley.
at 4:50 P.M. I made quick check too. The
pool (B) along the footpath has been reduced 1/3
since yesterday. A robin was unmistakably
perching on the congested tods (ready all Bufo)
