The initial terraformed area, outlined in black, expanded over the permanent sea ice and spread further north during the winter but neither the seals or polar bear developed regular seasonal colonies on any of the islands that experience seasonal sea ice during the time the reserve was open.

The plankton were a case of out of sight, out of mind and were only seeded once even though both the artic cod and ring seal populations had to be replenished, especially after ice fishing was offered as an additional activity to guests.

The initial terraformed area did not stay combined. The biome for elk, in brown, expanded south while the biome for smilodon expanded north. The bighorn sheep continued to live in both biomes while the rabbits stayed in the smilodon biome. The smilodons expanded their range into the elk biome during the warm summers and withdrew to their biome in winter.

The initial terraformed area, outlined in black, expanded fairly uniformly being held back by the mountain range only by the time the reserve closed and the planet was sold but the terraformed species had remained constrained to Serengeti.

The wilderbeast and zebra herds were surviving and evenly spread through the yellow area but Serengeti was the area that had to be reseeded with grass most frequently while the company operated and it was noted that the zebra herds relied heavily on browsing.

The initial terraformed area, shown as a black out line in the map below, has expanded north - in grey - and south - in green - by the time the reserve closed and the planet was sold but the terraformed species had remained constrained to Siberia. The grey patch reflects the extent of the evergreen forest and the dire wolf population. The green patch reflects the extent of the open woodland. By the time the continent was abandoned there was a small bison herd in the green area and two different mammoth herds in the grey and green areas. Both mammoth herds are smaller than their historic ancestors with the grey herd being as tall but slimmer and the green herd being just smaller in general.

Sessile Quad

The Sessile Quad is more cold tolerant, coping with temperatures down to 10C, because of its lower energy feeding strategy but requires upwelling. This results in a wider range than the sessile omnivore.

Neotenous Filter Feeder

The neotenous filter feeder has no control over its motion and does not tolerate water temperatures below 18C so does not form breeding populations outside this range although individual maybe found dragged astray by the currents.
