Data
A. Griffin Plots- Soils, Annual Productivity, Species
Abundance, 1971-1991
In 1991, Jim Griffin and Mark Stromberg re-sampled 40 plots on abandonded farm fields (1937-present) and relict Nassella grasslands on Hastings, as well as 40 plots on adjacent ranch land. These data are discussed in Stromberg, M. R. and J. R. Griffin. 1996. Long-term patterns in coastal California grasslands in relation to cultivation, gophers and grazing. Ecological Applications 6(4): 1189-1211.

C. Coastal Terrace Prarie Vegetation Data
From
1998 to 2002, Mark Stromberg, Vern Yadon and Paul Kephart sampled data
from California coastal terrace grasslands. These data are described
in Stromberg, M. R., P. Kephart and V. Yadon. 2002. Composition,
invasibility, and diversity in coastal California grasslands. Madroño
48: 236-252.
Several additional coastal terrace grasslands, not discussed in the paper,
were sampled are included below.

D. Distribution of Forest Trees in California
James Griffin, the long-time resident botanist at Hastings, worked with William Critchfield to map the distribution of forest trees in California and produced a publication by the USFS. This publication (Griffin, J. R. and W. Critchfield 1972. Distribution of Forest Trees in California. USDA Forest Service, Pacific Southwest Research Stations Research Paper PSW-82, 114pp.) has been scanned and can be downloaded either in its entirety or in smaller segments. This work includes distribution of trees based on the WIeslander maps compiling the natural vegetation of California (Jensen, H. A.(1947. "A system for classifying vegetation in California." California Fish and Game 33: 199-266.) and interviews with hundreds of regional foresters. By the way, these VTM maps are being digitized; contact Barbara Allan Diaz for more details. This publication (below) was scanned as a part of the Berkeley Digital LIbrary and we appreciate the support from this amazing project that made this possible.
