Grasses: A guide to identification using vegetative characters

Description:

Grasses are an important diagnostic component of many habitat classification schemes, including the National Vegetation Classification (NVC). Unfortunately most keys to grasses require examination of the flower heads, potentially limiting field surveys to only a few months of the year. Developed by highly experienced field botanist and habitat surveyor Hilary Wallace, this groundbreaking new guide uses vegetative characters to all the grass species found in the UK. It will help habitat surveyors carry out fieldwork for much more of year. This guide is aimed at habitat surveyors who need an easily accessible key to common grass species and also to those less common species that are diagnostic of more restricted habitats. The dichotomous key is accompanied by line illustrations of the diagnostic features referred to in the key, coloured photos of most species and notes on distinguishing features, habitat preferences and current distribution and status in the UK.
