Why are more goldenrod found in meadows than in a park?

Question

goldenrod is a type of flower/weed

Answer 1

I would imagine that in a park, the open areas would be mowed periodically.  This could prevent the plants from setting seed if the mowing would happen at the right time, so with less opportunity for reproduction, there would be fewer plants.  And depending on how the park was managed, the grounds crew may use weed killers to prevent species other than grass from growing.

And if the people who visit the park like the appearance of the goldenrod, some users may even pick the flowers.

A meadow would have less disturbance, so the plants would have a better chance of surviving and reproducing.
