The PlantPopNet protocol details data collection for Plantago lanceolata demography. The protocol is separated into two parts: A. Core protocol - the core data collection, which all sites will have to provide, and B. Add-ons data collection, which is optional. Core data collection described in the Core protocol will be used in the primary planned publications, while the add-on data will be used in additional publications. Please consider contributing to some of the add-on projects if you have additional time and interest.
A. Core protocol
The core protocol is easy and can be carried out with confidence by non-demographers. One person can accomplish the core protocol in about 12 hours/year, excluding traveling time. The effort may vary depending on site conditions and vegetation type. The establishment of permanent plots in the first year and the destructive sampling may take up an additional 6-8 hours. Involving a field assistant speed up the work process significantly.
Ideally data collection will run for at least 5 years and we are aiming for up to 10 years at a subset of sites. However, just one year of data collection is valuable and two years of data collection will be used to generate the first transition for a basic demographic model. Additional years will be used to examine temporal variation in dynamics and trait values.
Download the Core protocol and the four data-sheets ‘Site description.xls’, ‘Individual plant census.xls’, ‘Community plots.xls’, ‘Destructive sampling.xls’ available as a list below. Fill out and submit the data-sheets to the following addresses: firstname.lastname@example.org and email@example.com after each annual field census.
