The call would be logged as suspicious activity along with numerous other similar calls that day. Now if someone had called and said that there was a foot sticking up out of the ground it would be different, but this is not a drop everything and run over there with blue lights and siren type call once the offenders had left the area. As to calling another agency, that won't fly because agencies covering the same geographic area generally have unwritten, and sometimes written rules, about what agency handles what type of call. In a rural area, troopers generally handle traffic matters, Game Wardens handle game and fish violation along with recreational activities accident investigations, and SOs handle general LE matters. Now if there was evidence that they were hunting while they were planting flowers then a Game Warden might get involved.
