Maybe your state park already has its own species list?

No, I asked the environmental department of the Mountain Division, which covers Big Basin, and they've never heard of one. Our local university goes to a different redwood park, when we get students is is usually from Stanford.

Unfortunately I've no idea how to get information out of either of the Universities, Banana Slugs being researched in 2002 was my only success and that was due to a personal invite.

mentioned, I've limited permission to collect from State Parks land in my area, but can easily get anyone who is trained, introduced to the right parties so we can get a species list.

Well, then time start one! :-) Your name will initially be the most frequently found name on the list, then. But for most of the arachnological specimens, someone will have to inspect the specimen in order to establish the species. You are welcome to send (not too many) specimens to me, or perhaps someone closer is interested. (Thinking of Ken Schneider or R. J. Adams, for example).

I can take certain persons out to collect in the State Park, though I need to give advance warning, and it shouldn't be to hard to just get them permission as I've done with other experts in some of our areas which unfortunately, I am one of the experts of what is there, and I'm a volunteer and self trained in all of the environmental areas, except for watersheds.

Anyone interested in local collection can just e-mail me and we can get the ball rolling.

Maybe I can convince someone from my local University.... now to find a contact to get me a reference.
