Ray has worked extensively as a volunteer for the Canal & River Trust and has become increasingly focused on how the distribution and abundance of plants are related to the many ways in which people use and enjoy canals. In this book he explores how water plants in and alongside Yorkshire canals interact with human activity. Contents include:
A record of the plants found.
The impact of boating on plants and vegetation.
Plants in derelict and disused canals.
Effects of restoration of disused canals.
Relationships between plants and maintenance and management of canals.
Rare plants, native plants that are beyond their natural geographic range, and alien plants.
