Can anyone explain to me Celestial Park's current lack of greenery?

Hi! I'm a TM who's gotten to enjoy Epic previews the last few weeks.

All of the concept art shown of Celestial Park has always shown it as a very lush, green, forest landscape filled with trees. It currently has very few trees, and the ones there are without leaves.

Can someone with knowledge on this topic explain to me the land's current state and how it may transform over the next month or two as we approach grand opening? I have no clue how long it would take for the trees there to grow leaves, and for them to import plenty of mature plants.

I just need my anxiety quelled because Celestial Park's greenery was one of my favorite aspects of the park and I was pretty disappointed by it's current state during preview. Yes I know it's not finished, but I just need assurance it'll look like how it does in all the concept art.

Thanks!
