Excerpt from Initial Vegetal Development Following Prescribed Burning of Douglas-Fir in South-Central IdahoT 0 supplement these measurements, we have taken representative black and white and color photographs each year, both within the study area and from a permanent photographic point on the cross-canyon Slope facing the burn. No individual shrubs were marked prior to burning, but representative marked plants of each important shrub species have been measured and photographed annually since the fire.Calculations. -techniques for converting quadrant-distance measurements to estimates of plant density lack the mathematical proofs required for application to populations with unknown distribution. Several formulas can be used. To provide an empirical test of method, fieldwork in 1964 was expanded to include both the distance to the nearest shrub and a total count of all shrubs within 50 feet of sampling points. Since plant densities in the circular plots were similar to density estimates using the angle method, the angle-method formula5 has been used throughout the study.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
