Tempest in a teapot. I really don't care. Nature will find a balance with all the Earth life introduced on New Terra, not all species will survive the adjustment period, but some will. The Earth was always adjusting to changes in its environment and the loss of species, other species move in to fill the ecological nitches and some new creatures eventually evolve to carve out new nitches for themselves.
Oh by the way, here are the worlds of the Roosevelt Sector, this sector is known for its relative abundnace of intellegent native species and an aboriginal human civilization.

UWP Notes
I’ve converted the GURPS Traveller stats I originally generated this world data in to standard traveler stats with the following modifications.
The Size digits are incremented by halves so each ½ you see is actually part of the preceding size digit as I didn’t want to lose half size information upon conversion. Here they are:
