Oak seedling and sapling survival and growth in a California savanna under four herbivore treatments

Survival and height growth records for individual plants of Quercus agrifolia (n=4281) and Q. lobata (n=4268) from a long term experiment in mixed oak savanna at Sedgwick Reserve, Santa Barbara County, California. Plants were sown as acorns under 4 consumer treatments: no protection; protection from cattle; protection from cattle and deer; and, protection from cattle, deer and rodents. Acorns were sown in 1997, 1998, 2000 and 2001, and were monitored at least annually until 2009. Acorns and seedlings did not receive supplemental water.

本数据集收录了来自加利福尼亚州圣巴巴拉县塞奇威克保护区（Sedgwick Reserve）混合栎树稀树草原长期实验的两种栎树单株存活与株高生长数据，涉及海岸栎（Quercus agrifolia，n=4281）与裂片栎（Quercus lobata，n=4268）。实验以橡实为播种材料，共设置4组动物取食防护处理：无防护、防牛、防牛与鹿，以及防牛、鹿与啮齿动物。实验分别于1997、1998、2000及2001年开展播种，并自播种后每年至少进行1次监测，直至2009年。所有橡实与实生苗均未施加补充灌溉。
