Methods for surveying habitats

The methods described in Section 6.1 may be applied to the surveying and monitoring of most habitat types. Section 6.1.1 provides an overview of remote sensing technology, which includes both satellite-based remote sensing (Section 6.1.2) and aerial photography (Section 6.1.3). Remote sensing, Phase I habitat mapping (Section 6.15) and National Vegetation Classification (NVC) surveys (Section 6.16) are principally survey techniques for mapping and/or quantifying the extent of different habitats at a variety of scales. This may be carried out for a number of different purposes:
