Urban Ecology
Mosses like juniper haircap are quiet workhorses of healthy ecosystems — they retain moisture, prevent erosion, and signal good air quality, all of which affect the health of gardens and green spaces you walk through every day.
Someone found and photographed a juniper haircap moss growing along Boones Ferry Road in Lake Oswego, Oregon, and enough people on iNaturalist agreed on the identification to make it 'research grade.' This little moss — named for its resemblance to juniper needles — is a native species that thrives in well-drained, open areas. Observations like this help scientists track where plants are living and how their ranges might be shifting over time.
