I would say moderate [predator pressure] at least. Mainly raccoons, weasels, fox, and maybe a coyote. From above just standard birds of prey as I have seen Hawks and actually just rescued a kestral (they shouldn't bother chickens) during a storm
I mainly worry about hawks and Bald Eagles during the day. Bird netting over the chicken run has deterred any aerial attacks. My 2X4 welded wire chicken run fence, without a predator apron, has been good enough to deter the occasional neighborhood dog that might pass through during the daytime. If the chickens go on alert, they all run back through the pop door and into the coop.
I lock my chickens up in their Fort Knox coop at night. Probably take a bear to get in that coop when locked up tight. Most of the nighttime predators cannot get into the coop. So far, no attacks in 2+ years.
As already mentioned, the predator apron probably works better just laying on the ground or maybe burying it an inch under the dirt if you plan on mowing there. The idea is that they might try to dig by the fence, hit the unseen predator apron, and then give up. From what I have read/heard, predators don't like to dig long tunnels (2 foot apron) because they fear they might get caught/trapped in the tunnel.
The 1/2 inch hardware cloth should keep out weasels, but do they hunt during the daytime? If you have a predator resistant coop, and lock your chickens up at night, that might be a better strategy. If you don't lock up your chickens at night, then the 2X4 welded wire fencing is not going to stop a weasel. I put most of my money into the Fort Knox chicken coop security because I was more worried about nighttime predators.
We have different predator concerns based on where we live. FWIW, your chicken run is a lot more secure than my chicken run. Nice job.
