Hi, I am interested in the populations of Baltimore Checkerspot
butterflies in Massachusetts 1993-2003. Population surveys in Essex
county of particular interest. Thank you.

Hi cooper99-

I've been working on your question and so far have not found the data
you want on-line.  However, I've sent e-mails to several persons who
may know how one might access such information, which I believe
probably exists at least for the past few years.

I'll keep you posted.

Hi Cooper99 --

I'm afraid I'm not having much luck in tracking down data on the
Baltimore Checkerspot in Massachusetts.

I've gotten one reply to my e-mails:

Nellie,
 
I don't have any detailed info regarding this species in Essex County.
What I can tell you is that we observe two known breeding sites; one
being on Rte 113 in West Newbury in a field that has been used for
horse training and shows, and another site at Ward Hill. Both these
sites have populations that flucuate from year to year, but we have
found butteflies at each for the past five years or so.
 
I'm not sure how much this helps, and I don't know of anywhere else I
can point you for additional info. However, if you have any specific
questions, do write back.
 
Best,

Perhaps another researcher can find a source I've missed.
