I read much of the information in the URL you posted and have some questions.
I must confess that I never heard of an MPLA before this. However, as I read the info you ferreted out, I saw fishing and invertabrate harvesting restrictions. I saw no restrictions of surfing, wading, scuba diving or other such activities. So, my assumption is that this will mostly affect spear fishing and sport fishing. Is that a correct interpretation? If not, please point me in the right direction.
As I read the material I "discovered" that such areas already exist up and down the state. Since I do not dive in California, I guess my ignorance can be excused? From what I read there will not be a general prohibition against spearfishing, but very specific restrictions. It appears that Southern California already has restrictions. For example, Point Cabrillo reserve cannot be "fished" for "all recreational species; all commercial inverts except lobster, sea cucumber and crab," It can be "fished" for "commercial fish, commercial lobster, commercial crab,commercial sea cucumber, commercial kelp (except bull kelp)". Is that the way you read it?
Do people dive at Point Cabrillo now? Please pardon the ignorance again. Do they spearfish there? If so, I think that is the "model" that is being proposed.
I am not sure I have my arms around this...a hard copy is easier to read than a CRT copy. I am getting ready to go on a trip and will be away from computers, etc for a month. So I am not sure how much help I can be. Someone has to study the details of this and really understand it thoroughly in terms of what is now in place and what is proposed. I am far from that now.
If you have a hard copy, can you tell me where you got it? I'd like to help, but the timing is damn bad for me....
