The State of Butterflies in Jersey (el. knyga) (skaityta knyga) | knygos.lt

Aprašymas

In 2004 the States of Jersey established the Jersey Butterfly Monitoring Scheme (JBMS) as part of its commitment to environmental monitoring. Members of the public were recruited to count butterflies at 38 locations across the island. During the first ten years of the JBMS these volunteers walked over 3,600 miles and counted exactly 122,279 butterflies. This book unveils the results of the JBMS's first ten years of monitoring. The butterfly records are analysed and combined with habitat data, historical records and other information to offer an insight into the diversity, abundance and status of all Jersey's butterfly species. As might be expected, the picture is mixed with some species doing better than others. The health of Jersey's butterflies is discussed and suggestions are made as to how species' populations and diversity can be encouraged to expand cross the island. This book also summarises historical records and acts as a guide to all of Jersey's known butterfly species from the past and present. Features of this report include: A guide to all of Jersey's current and historical butterfly species. A summary of ten years of intensive butterfly counting. Clear colour photographs of all the species featured. Information on the health of Jersey's butterfly populations. Advice on the conservation and promotion of butterflies.
