checkout the actual forest in Google Maps[1]. If you check the historical imagery in Google Earth Pro, you'll see that sometimes between the end of 2017 and the start of 2018 most of the trees kinda disappeared. I dunno if the forest was cut down or if they just stopped watering it, but its pretty much gone now
