Direct or predictive mapping?

Maps on marine benthic vegetation distribution and abundance is a key component for sustainable management and planning of coastal areas! The question is how to get them.

In principle there are two fundamentally different approaches, direct or predictive mapping. In order to produce comprehensive maps of vegetation from direct measurements, it is necessary that the distribution can be measured using some kind of remote sensing technique or that the area is sufficiently small that it allows a complete ground-based survey.

Predictive mapping is a good alternative
Predictive mapping is the only alternative if the level of detail, environmental conditions or costs limits the collection of data to small-scale sampling of a tiny fraction of the area of interest.

The focus of PREHAB web-resource is predictive mapping through statistical modelling. Some information about direct mapping of biodiversity is found here.
