I don't know if you will see this as this is an older thread, but I live in the Humboldt/Del Norte area. The dispatch center uses 'North Coast' as their call sign. They dispatch Six Rivers National Forest (SRF) and Redwood National Park (RWP) on their own respective frequencies. They will often simulcast both agencies when reading the morning report and giving staffing levels and fire weather forecasts. Sometimes though they will not simulcast and give the same reports on each channel separately. As far as I know, they do not dispatch for BIA-Hoopa. Hoopa does their own dispatch as they are also an all risk fire dept. There is no fire dispatching for FWS as there are is no fire program here. They may dispatch for BLM as there are 4 repeater sites in Humboldt county and a fire station on the Lost Coast. When North Coast gives their morning report they will do resources available for BLM, BIA-HOOPA, CAL Fire, SRF, RWP, and smoke jumpers out of Redding. Hope this is helpful if you need more details let me know and I'll see if I can answer them.
