Question for arborists working in parks and recreation

Howdy! I'm a park maintenance guy who is just about eligible for the ISA arborist certification. I haven't been able to get a climbing job, but I'm curious what other areas are available maybe on the ground with a parks degree, some experience and an ISA cert. I've done some limited land management including prescribed burns. Chainsawed a good deal on the ground. I guess I'm curious about other areas besides tree maintenance that people do for parks departments.

Thanks!
