Sedgwick Reserve

This project attempts to measure the importance of the food resources in the acorn and the effects of location on the early growth of the Valley Oak (Quercus lobata). Acorns were obtained in 1997 from 44 'mother' trees growing at five localities within the range of the Valley Oak, and were planted in a randomized manner in a 21 x 21 grid at the Sedgwick Reserve in Santa Barbara County. The size of the acorn was noted at the time of planting. After 1997 the survival and growth of the seedlings was monitored on an annual basis during the first five years of growth. Survival and growth of the saplings is continuing to be measured, with respect to the origins and sizes of the acorns. The size of the sapling through time is being examined to determine the effects of initial food resources on later survival and growth. The plants originating from Sedgick trees are acting as the 'control' for the effect of geographic origin of the plant.
