Abstract: The Cub Hill urban tower estimates C sequestration for this highly vegetated "non-forest" urban/suburban landscape and is influenced by anthropogenic CO2 emissions. As part of a Report to Congress, new emphasis from Forest Inventory and Analysis (FIA) will provide intensive site monitoring on Forest Service Experimental Forests and Ranges related to Climate Change. We will validate carbon uptake/emissions estimates from the Cub Hill urban eddy flux tower by re-measuring 2004 plots for annual productivity, ~75 Urban Forest Effects (UFORE) plots in and around immediate tower area. Re-measurements of urban-rural lots will give us estimates of land use change and carbon gain /carbon loss in comparison to flux and remote sensing estimates. This work will include existing urban-to-rural gradients with CO2 and meteorological monitoring from the Baltimore (Maryland Science Center at the Inner Harbor, Cub Hill Experimental Forest) to the Silas Little Experimental Forest. The FS National Climate Tower Network will upgrade existing (or new) flux towers. These meteorological upgrades include precision temperature sensors and rain gauges featuring triple redundancy on the sensors and data loggers which makes us compatible with NOAA's US Climate Research Network. In addition, we have operational carbon isotope monitoring of 13C / 12C at the site. This work will improve our understanding of human disturbances on ecosystem carbon stocks and the ability of urban forests to adapt to changes in climate and the atmospheric composition of greenhouse gases.
