Why does decorations lower an islands attractiveness?

[City Builder]

I have a couple extra islands that I'm not doing anything with at the moment. I keep getting messages every now and then about how visitors want to visit (insert island name here) island. So I built a visitor pier. Then I try to cover a large area of the island with decorative items and my islands attractiveness goes down.

Any clues why this is?

You may be loosing more from taking over the natural space with ornaments.

Ornaments are really not worth it for just attractiveness and more for just making your city look different really and to your liking.

You can see this when you open the attractiveness window also.

I've always wondered how 'Nature' is calculated into Attractiveness points. Is it a standard amount of unused grids make up a point and does reclaimed space from factories automatically put back under 'Nature'?

You can see it when you open that menu before and after removing buildings like that.
