Trail Crew?

I went hiking here with my daughter and dog saturday morning. I was just wondering if there is any kind of trail maintenance crew that keeps up with the trails. They seem to be in pretty good shape. Also it looks like a great place to get my kid into riding.
Watch the ticks,my buddy is a ranger and says its the worst place in nj, i even remember a big sign there with a picture of a tick warning. Never been back since, Def had some potential.
Love this park, done hiking here in the past. The park lists biking only on the yellow trail but I see in older posts people have rode the white(hiking only) trail. wondering about this since I have hiked the white and it is a really nice trail.
