Vegetation Conditions

During summer 2007, ICWD research assistants reinventoried 109 parcels.  These tables (csv / pdf) show total perennial cover for all parcels in all years in which they were reinventoried, and LADWP baseline data from the mid 1980s are included for comparison.  Methods employed in 2007 were the same as methods used in previous years (see previous ICWD annual reports and Vegetation Scientist reports).  Landsat satellite data were obtained and interpreted for all reinventoried parcels.  The attached graphs (ppt, example below) show ICWD field cover measurements (top graph), and total living (green) plant cover in each parcel during late summer of each year derived from the satellite data (middle graph).  The bottom graph shows estimated April depth to water table (averaged beneath entire parcel) according to interpolation procedures implemented by ICWD hydrologists.  Depth to water estimates for 2007 are not available.
