Two South Florida public schools are named in her honor: Broward County Public Schools' Marjory Stoneman Douglas High School and Miami-Dade County Public Schools' Marjory Stoneman Douglas Elementary School.
She developed a rivalry with an editor at The Miami Metropolis whose greater familiarity with the history of Miami gave her cause to make fun of Douglas in writing.
Some of Douglas' stories were collected by University of Florida professor Kevin McCarthy in two edited collections: Nine Florida Stories in 1990 and A River In Flood in 1998.
Her ashes were scattered over the 1,300,000 acres (5,300 km2) of the Marjory Stoneman Douglas Wilderness Area in Everglades National Park.
Douglas characterized the Everglades as ecosystems surrounding a river worthy of protecting, that was inescapably connected to the people and cultures of South Florida.
Douglas began accruing honors since her early days writing for The Miami Herald.
Despite blindness and diminished hearing, Douglas continued to be active into her second century, and was honored with a visit from Queen Elizabeth II, to whom Douglas gave a signed copy of The Everglades: River of Grass in 1991.
The South Florida Water Management District began removing exotic plants that had taken hold in the Everglades when Douglas turned 102.
When the Central & South Florida Project (C&SF), run by former members of the Corps of Engineers, was proposed to assist the Everglades, Douglas initially gave it her approval, as it promised to deliver much-needed water to the shrinking Everglades.
Douglas was known for haughtily dismissing reporters who had not read her books and asked uninformed questions.
Regardless of her dedication to the preservation of the Everglades, Douglas admitted the time she spent actually there was sporadic, driving there for occasional picnics.
