The methodology is frequently used for initial assessment purposes and Aluco Ecology provides an extended service to assess the evidence of, or potential for, protected species on the site.Phase II habitat survey: Phase II surveys are more detailed than Phase I and concentrate on specific plant community types. After a preliminary or Extended Phase I survey, detailed sampling can be used to record species composition and frequency. The information is then considered against the National Vegetation Classification (NVC) system.Hedgerow survey: Hedgerow surveys may be required to determine the status of a hedge under the Hedgerows Regulations 1997.
