it looks faked in as much as the trees in the foreground are illuminated and can be seen in green color....
of course the heads may be illuminated by flood lights, I dont think you would see the stars that clear and the foreground with all the ambient light.
also in contradiction to the text....polaris does not line up with the big dipper as it points to the second star in Ursa minor and not polaris....
Arcturus does appear in the right spot.
It looks like the trees are illuminated by lights form a visitors center or parking lot. They are illuminated form a low angle up so it might be the same lights as the heads. It looks like a time laps photo to me. I took some time laps photos of a city and did not notice they were night until I looked closely at the lights and the windows.
Time lapse for sure, maybe a longer-than-normal shutter? I’m not a photographer, but I know enough to be dangerous.
Also, agree on the Polaris part. The straight line is an easy way to find the reference, but that second star is not Polaris.
Good catch!
