Spatial pattern dynamics of oak mortality & disease symptoms

Kelly, M., D. Liu, B. McPherson, D. Wood and R. Standiford. 2008. Spatial pattern dynamics of oak mortality and associated disease symptoms in a California hardwood forest affected by sudden oak death. Journal of Forest Research 13:312-319

We used two-dimensional spatial analysis tools with data gathered in point-centered-quarter format in 2001 and 2004 to quantify 1) population density of the disease through time; 2) spatial pattern of tree mortality across scales through time; and 3) spatial co-occurrence of disease symptoms with crown mortality through time.
