There is a butterfly up here, (iirc, the Dakota Skipper butterfly) which a group tried to put on the endangered list. They stated they only were seen for a couple of weeks, and there were not very many of them.
A check of research on the butterfly disclosed that the particular species had been noted in surveys in the early 1900's before much settlement or agricultural development in the area, that they were only seen for a couple of weeks, and there were not very many of them.
In other words, that was their normal state of affairs, and not a result of being endangered.
I was wondering if the striped rabbit was once more prevalent, or if in a similar situation to the butterfly.
