Wildlife Damage Management Conference Proceedings
We conducted surveys of federal officials nationwide and of local officials in California to determine historical and temporal aspects, location, size, and control of American crow (Corvus brachyrhynchos) urban roosts. The national survey consisted of a 2-page questionnaire sent via email to United States Department of Agriculture Wildlife Services state directors representing the lower 48 states. The California survey consisted of a 3-page questionnaire mailed by the League of California Cities to 473 towns and cities and an email inquiry sent to Agriculture Commissioners in 29 counties. In the national survey respondents in 27 of 39 states identified 86 urban …

Global Positioning System (GPS) data from five sites on the stable interior of the Sierra Nevada block are inverted to describe its angular velocity relative to stable North America. The velocity data for the five sites fit the rigid block model with rms misfits of 0.3 mm/yr (north) and 0.8 mm/yr (east), smaller than independently estimated data uncertainty, indicating that the rigid block model is appropriate. The new Euler vector, 17.0°N, 137.3°W, rotation rate 0.28 degrees per million years, predicts that the block is translating to the northwest, nearly parallel to the plate motion direction, at 13–14 mm/yr, faster than …

Analysis of more than a decade of high-quality data, particularly those from the two-color electronic distance meter (EDM), in the Parkfield, California, area reveals a significant transient in slip rate along the San Andreas Fault. This transient consists of an increase in fault slip rate of 3.3 ± 0.9 mm/yr during 1993.0 to 1998.0. The most reliable fault creep instruments show a comparable increase in slip rate, suggesting that the deformation is localized to the fault which breaks the surface. There was also an increase in precipitation around 1993. It is unlikely, however, that this anomaly is due directly to …
