Pokemon Go The Seasons Change: Part 1 Timed Research Tasks Guide

Here's what these tasks ask you to do!
A special Autumn Event is going on now in Pokemon Go, which is causing certain Pokemon (like Oddish, Bayleef, and Vulpix) to appear more often in the wild.
During this event, players can complete a new series of Timed Research tasks called “The Seasons Change: Part 1.” While the Autumn Event itself will end on October 12 at 1 p.m. PT, you have more time (11 days, as of this writing) to finish these new Timed Research tasks.
