Forests that had been leveled by hurricane winds or burned to the ground during firestorms regrow from seedlings. Within a few decades, young forests have reappeared, as have lush meadows and marshlands. Opportunistic vegetation eventually gets pushed aside as the climate worldwide returns to normal. For hundreds of years, however, the vegetation in any given region may have a different appearance that it will ultimately, due to this type of adjustment. Wildlife, being mobile, rebounds more readily than the vegetation.
Wildlife tends to wander until it finds a hospitable home, and there park until matters improve.
Many species will seem extinct, where they are merely decimated in number and staying close to where conditions are optimal. As they regrow in numbers and the habitat improves, they return to their venturesome ways, and thus, to mankind, seem to suddenly reappear. Fish fare better, particularly if ocean going, as the oceans are not traumatized in the same manner that land life is. In fact, due to the increased carbon dioxide in the air after a pole shift, the kelp and other plant life in the ocean thrives, creating a life cycle reaction that benefits ocean life. As man, the great plunderer, has essentially disappeared, species that had almost gone extinct will be on the rebound.
