I messed with an old green maple

[Calidoscopelove]

Im sorry.. I'm deeply saddened by what I've done in an effort to try and help an old green maple in our front yard... the poor thing was covered in Boston ivy and so I went ahead and ripped it all off from its roots to its branches... in the process I found a big baby tree on the top of the trunk in the center of the branches which I ripped out to find a deep pocket which I emptied out and then it just filled with water... I regret removing the baby because it drank the water and was the trees baby... I attempted to keep it dry by emptying the water out of the reservoir and found weird swimming creatures that were unidentifiable as well as what could've been white mushroom pulp ? 

 

also on the side was a medium size of some rotting bark I uncontrollably dug out pretty deep and now water pools in there mushrooms and moss grow there now... 

 

I was unsure what to put in the 2 reservoirs so I just left it alone while I traveled for a few years.. now I'm back and wondering if I should do anything or what I can do?
