Amboseli Elephant Database
The main database (in Access) comprises visual on-the-ground sightings by (over the years) sixteen observers of (now) 53 elephants families (ca. 2000 known individuals) of the Amboseli elephant population from September 1972 until the present. Each record (n greater than 30,000) of the main table includes the following fields: date; time; daily record sequence; group type; location (by 1 km grid square and since 2000 by GPS UTM coordinate); habitat type at beginning and end of observation; group size; number of bulls; quality of the count; bull age classes; presence of musth males; presence of estrous females; activity of group; ID of observer; quality of individual recognition of females and males. Linked tables include: individual IDs; family IDs; habitat types; activity types; observer IDs. Ancillary databases include demography (dates of births, deaths, cause of death); rainfall (since 1972); watertable (since 1984); 10 vegetation plots; behavioral postures; digital photo IDs; vocalizations. Since 2002 a GIS database (in ArcInfo) has been maintained incorporating ca. 100 geographical, geo-physical, hydrological, vegetation and elephant distribution layers.

Sampling, Processing and Quality Control Methods
Step by Step Procedures
Daily reconnaissance drives in 4x4 vehicles on- and off track to locate and record elephant families in relatively open bushed and wooded grassland. Data recorded on pro-forma datasheets and entered daily into Access database. Ad hoc reconnaissance in low-flying light aircraft.
Sampling Area And Frequency:
Temporal: continuous and on-going since 1972.
Spatial: observations concentrated in core of ecosystem, essentially the 390 km2 Amboseli National Park (2deg40minS, 37deg15minE).
Ad hoc, adventitious search patterns guided by expert knowledge of elephant diurnal habits and constrained by park road system and topographic and hydrologic features.
