Firefighters are conducting controlled burns at Sycamore Grove Park near Livermore through Monday.
The vegetation management is removing weeds and promoting the growth of native plants and flowers, according to the Livermore-Pleasanton Fire Department.
The fire department has been working with the Livermore Area Recreation and Park District for years managing the park's vegetation, at times with fire, a natural part of the California ecosystem.
During the controlled burns, firefighters will conduct training exercises, studying the fire behavior and practicing coordinated attacks on wildfires.
During the controlled burns, firefighters will be monitoring for humidity, wind and temperature and working with the Bay Area Air Quality Management District to make sure the air quality impact is minimal.
