Tips for submitting high-quality data
PAMF uses data collected by its participants to update the learning model in order to provide efficient and effective Phragmites management guidance. Ensuring that data are collected in a standardized format is critical to providing high quality guidance. Check out our tips for reporting the best possible data to avoid some common mistakes when you submit your next monitoring and management reports!
read moreHow does PAMF’s model use participant-collected data?
Ever wonder what PAMF does with all that data you collect? PAMF’s standardized protocol has you collecting data from stem counts to percent establishment, management actions to costs incurred. In this blog post, we’ll lay out in a bit more detail how these data inform PAMF’s statistical model and site-specific guidance.
