Answers:    for sealing around the tree, find an old inner tube and wrap it around the branch a short time ago above the roof. Attach it to the tree with any a couple of zip ties or some nylon rope. Then using roofing nail if you can, attach it to the roof around the opening. If you enjoy holes else where and requirement a cheap quick tarp, be in motion buy a vinyl shower curtain at the dollar store or a big lots or walmart. Might be able to use the eyelet holes to attache it.
If the roof is not going to be to big, you may know how to get a veranda umbrella to use.

Duct tape? Tarp? Some insulating foam that expands (the type used around doorways during installation of the jamb)? Tile grout? acting wood planks? Metal sheeting/flashing?
