Excerpt from Instructions for Making Plant Survival Surveys in Region 8The intensity of field work will depend upon the degree of accuracy required, the size of the planting, and the information desired, as well as upon the amount of time and money available. The initial survey will cover not less than ten samples of 25 individuals each well distributed over the planting area. The final count, if needed, should cover the area in more detail, the number of samples depending upon the accuracy required. The final standard error of the mean must not exceed i:5% for these surveys.Plantings containing 1000 or more individuals will be treated statistically, those with less than 1000 individuals will have the actua survival percentage determined. These small plantings should be isolated and not directly related to any other planting.Survival surveys will be made following the critical periods and before the leaves have fallen. One and often two survival surveys will be necessary annually.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
