1930
Some of the animals were dispersed during the Depression to other zoos-only small group of animals remained. Zoo correspondence from the 1930’s refers to quite a few animal purchases in 1929-32, then letters referring to food costs and efforts to keep animals and increase zoo budget. There were sales of some of the animals later in the 30’s. There is documentation that the Zoo also boarded animals for the DNR during the 1930’s. The Park seems to have remained busy with concerts and events.
1948
Once the World War II is over, city residents begin to protest decline of park and zoo.
