Mark your calendars for the 2019 City Nature Challenge! Cities around the world will compete over a four-day period to make the most observations of nature, find the most species, and engage the most people. San Diego is participating for the second year in a row. Last year, we placed in the top three in each category, and we want to meet or beat that record this year.
