(CBS) — The Cook County Forest Preserve District just finished a year-long centennial celebration. A documentary, premiering at 7 p.m. Sunday on Channel 20, captures its evolving mission.
When landscape architects Dwight Perkins and Jens Jensen first proposed saving open space in Cook County early in the 20th Century, it was a radical idea that took several years to gain acceptance.
Over the years, its holdings have grown to nearly 70,000 acres.
Forest Preserve District spokesperson Lambrini Lukidis says at first, its value was mostly recreational. Now, she says, the environmental mission has gained equal importance and says it includes protection of flora and fauna found nowhere else in the United States.
