Russ, it sounds like they're following the model we use here in Pennsylvania (don't know if we originated it). The basic idea, as I heard it explained to me, was that our DCNR (=DEP) people anticipated funding cuts, more deferred maintenance, and so on, and wanted to set up a structure that could backfill some Parks and Forests needs with volunteers. It would act as a sort of "civilian auxiliary" to the paid State structure: the overall foundation sets some broad guidelines, but it's divided into chapters organized for individual parks or forests. The chapter officers are volunteers (the relevant park or forest superintendent is an ex officio board member). Typical activities are fundraising, maintenance or minor building projects, and nature/historical programming, in my experience.
My chapter is a little weird because we're attached to a state forest with some large, relatively primitive parcels, so a lot of our work is maintenance/ecological restoration. I assume any volunteer group attached to the Pinelands state forests would turn out in a similar way. It does let some things happen that would proably not get done by State people due to budget or time priorities (whether driven by lack of resources or maybe politics). I'm not sure this foundation is the right tool for the general problem being discussed here, but my general experience is that it's had a positive effect in letting people who are not State employees improve the condition of State lands.
(Hi, everyone, BTW. I've been lurking here for about 20 years before registering--yes, I remember the old forum software with the member galleries--and most of the botanists know me and can probably guess who I am from my avatar and my usual habitat on a different set of barrens to west'ard.)
