Baits that can be crafted by the survivors team and placed on the ground. Different types with their own crafting requirement, like one for herbivores and carnivores. Would appear on the dinosaur's scent radar but provide very little or no actual food.
Because DA would come close in search of food, this gives survivors easier access to hunting dinosaurs for crafting recipes (if that's like .. . planned?) or just poaching. Maybe fun for the actors too?
Could also have a professional variant for use by GNR in testing
