OHV2 would be the OHV unit supervisor on the Trabuco Ranger District. That person would work Ranger District wide, not just at one particular area. There should be other OHV units which would be OHV21, OHV22, etc. Budget cuts may have eliminated these other units, leaving the supervisor working alone. Wildomar might take up most of the workload and OHV2 might only have time to work it without getting out to the rest of the district.
Second, I count 13 LEO's. That must be nice. Up here on the Inyo I believe there is only one, 4 Charles 1. They can't seem to keep the more field going officers positions filled. Especially the position on the Mammoth Ranger District.
First time I heard and wrote down the OHV callsign so I imagine there are more I've not yet paid attention to and recorded. There could be callsigns assigned to seasonal people and maybe some are dormant? Wildomar is a designated area for OHVs but has only 8 miles of trails so it won't need a bunch of OHV units. The other OHV areas are a lot further south. https://www.fs.usda.gov/activity/cleveland/recreation/ohv Wildomar has been closed due to the onslaught of fires so not much OHV call sign radio activity.
I think the LEOs I've heard are patrolling all of CNF and since CNF is an oasis in the middle of heavily populated areas (as opposed to INF) I can imagine the number of officers is appropriate.
Also a reminder that when I listen to the Forest Net link frequency I am hearing all of the repeaters, not just those in Trabuco.
