Botanical Surveys, Aquatic Plant Surveys, Vegetation Description and Analysis

Five Valleys Ecology hold specialisms in aquatic and terrestrial botanical surveys, and vegetation description and analysis.

Sainfoin (Onobrychis viciifolia), yellow rattle (Rhinathus minor) and fairy flax (Linum catharticum)

We have capability to undertake detailed surveys of a wide range of terrestrial and aquatic habitats, and analyses of vegetation datasets including:

  • Detailed botanical surveys including the National Vegetation Classification (NVC) methodology;
  • Hedgerow surveys using the Hedgerow Regulations 1997 methodology;
  • Aquatic plant surveys including the Mean Trophic Rank (MTR) methodology;
  • Multivariate statistical analysis of vegetation datasets using TWINSPAN and ordination with DECORANA;
  • Analysis and interpretation of vegetation data using Ellenberg Indicator Values;
  • Spatial analysis of vegetation datasets using Geographic Information Systems (GIS); and
  • Vegetation description and analysis using the Braun-Blanquet school of phytosociology.
