چکیده
2 Wildlife biologist, George Whittell Wildlife Rehabilitation Center, Monterey County SPCA, Monterey, California; Senior Associate, Philip Williams & Associates, San Francisco. Abstract: Avian abundance and diversity were measured at 5 sites in the riparian zone of the Carmel River, selected to represent different conditions of riparian vegetation, in the spring of 1983. Vegetation varied from lawn (golf course) to mature, undisturbed riparian forest dominated by black cottonwood (Populus trichocarpa). Birds were counted along 700-meter transects on 10 occasions. The abundance and diversity of birds varied directly with the abundance and diversity of the riparian vegetation. A narrow strip of riparian trees tripled the number of species observed at golf courses. Scattered residential development did not effect the number of birds observed in mature riparian forest.

Groundwater is closely coupled with stream flow to maintain water supply to riparian vegetation, parti cularly where precipitation is seasonal. A case study is presented where Mediterranean climate and groundwater extraction are linked with the decline of riparian vegeta tion and subsequent severe bank erosion on the Carmel River in Carmel Valley, California.

Due primarily to alteration ofriparian vegetation and nest parasitism by brown-headed cowbirds (Molothrus ater). the least Bell's vireo (Vireo bellii pusillus) has under gone a tremendous decline in range and numbers since the 1920's. In 1987. we sampled vegetation at 32 nest sites to characterize nesting habitat ofleast Bell's vireos in the Santa Ynez River drainage. Most next (59.4%) were lo...

[1] We mapped the geometry of a shallow confining layer within the Salinas Valley aquifer system, northern Monterey County, California, using indicator geostatistics. The confining layer was previously interpreted to be mainly Holocene in age, having been deposited as a single unit during post-Wisconsin sea-level rise. We interpret this layer in our field area to be associated with Isotope Stag...

We examined the distribution of ground-flora species (herbaceous and woody species <1 m tall) across riparian areas of northeastern Wisconsin in an effort to understand how hierarchical landscape properties, such as the physiographic system (ground moraine and outwash plain), valley system (constrained and unconstrained), and valley floor landforms influence distribution patterns of ground-flor...
