Final answer:
In the humane hierarchy, management strategies like using crates and gates are part of the second tier, which aims to manage the animal's environment in a non-invasive way to prevent undesired behaviors. This model ensures ethically applied behavior interventions in animal care professions.
Step-by-step explanation:
The question refers to the humane hierarchy, which is a framework used in animal behavior management to ensure that interventions or modifications of behavior are applied in an ethical and humane manner. This concept is widely adopted in fields such as veterinary behavior, animal training, and shelter management. The use of management strategies including crates and gates is on the second tier of the humane hierarchy, after the first tier which emphasizes health, nutrition, and physical environment. The tiers escalate in invasiveness and potential for aversion or harm to the animal, with Tier 1 being the least invasive and Tier 5 involving physical corrections or aversive methods that should be used as a last resort.
The second tier, where management through crates and gates falls, is focused on changing the environment to prevent the unwanted behavior and is considered non-invasive. For example, if a dog has a habit of rushing out the front door, using a baby gate to block access to the door would be a component of a Tier 2 intervention. The goal is to manage the situation to prevent the behavior while exploring other tiers such as positive reinforcement to train an alternative desirable behavior.
