The new window at Historic Takoma (7328 Carroll Avenue) features the story of the work of at least 40 botanists who visited the Sligo Creek watershed between 1876 and 1915, collecting about 700 plant specimens for deposit at the herbariums at the Smithsonian and the University of Maryland. The display is a work of a partnership between Historic Takoma and Friends of Sligo Creek.
Plant collecting had been popular as an amateur pastime and scientific activity since the early nineteenth century and peaked in the Mid-Atlantic between 1900 and 1910. Dozens of botanists arrived in the DC area between 1884 and 1910 to work at the USDA and Smithsonian.
Learn more about these collectors, their work, and the mystery of the Takoma Bog when Michael Wilpers from Friends of Sligo Creek presents a talk at Historic Takoma at 7:00 PM on Wednesday evening, October 9.
In 1918, botanist Waldo McAtee documented 36 wetlands he called “magnolia bogs” across the Washington region, including the one called the Takoma Bog. Such wetlands formed where groundwater emerged from a seep onto gravel and sand overlaying impervious clay. They covered less than an acre and were surrounded by Sweet Bay Magnolia.
The Takoma Bog’s location remains a mystery. A botanical report from 1896 notes a “sphagnum swamp near Takoma.” On two plant specimens from 1904, the labels indicate they came from a “bog, near Takoma Park, DC” and a “sandy swamp near Takoma Park, DC.” These hints and local geography suggest the bog might have been located on the uplands above the headwaters of the Takoma Branch, a tributary of Sligo Creek, where it was later buried in pipes underneath Kansas Ave., between Blair Road and Eastern Avenue.
