Aoba Ward Creature Information

I would like to introduce the observation card of living things.
We can download PDF data which creature information in ward was published from each link.
Introduction of familiar nature observation
What is the number of cicadas that live in parks around the city?
The cicada sounds loudly every year in summer.
I checked how many cicadas live in one park in the city.
Cicada leaves a shell when it becomes an adult.
When Ichigao Daiichi Park (area: 2,477m2 opened: June 1975), shells were collected early in the morning from July 18 to September 27, 2013 (Heisei 25). It turned out that many cicadas live in one park as follows.
| The cicada shells confirmed | Number of units | Appearance rate |
| Abrazemi | 3,227 | 84.7% |
| Minminminzemi | 410 | 10.8% |
| Niizemi | 3 | 0.1% |
| Squirrel | 2 | 0.1% |
| Unknown (Abrazemi or Minminzemi) | 167 | 4.4% |
| Total | 3,809 |
We summarized what we learned from the survey of cicadas and created a nature observation card.
You can check what kind of cicadas from the shell.
