Fig 1.
Current distribution of AHBs in California.
Percentage of AHBs in each county sampled by the present study only are shown. Counties highlighted in red have been found to be inhabited by AHBs. Counties in pink had no AHBs, but had poor sampling.

Fig 2.
Probability of sampling zero AHBs for all counties sampled without AHB presence using the binomial distribution.
For Yolo, for example, there was over 80% chance of sampling zero AHBs assuming AHBs are present at 2.5%. Yolo, Sutter, Placer, and Butte were sampled with insufficient depth to rule out significant AHB presence.
