Upgrade of Project

The RedList (s Afr) is being upgraded.
After almost two decades CREW is simplifying its data collection protocols to those data that are crucial to the red list assessments, and ditching its two signature projects CREW Species and CREW Sites, to the data collected by the casual observers.

Unfortunately, this means that two new fields must be added to this project.

  • Population Size & Extent: an estimation or count of the number seen and over what area.
    This remains the same, but you are requested to please be formulaic along the lines of 43 plants in 2ha, or over 100 plants along a 50m transect. - so how many plants did you see in what sort of area. You are welcome to add extra information, such as adults vs juveniles, numbers
