A Ruffed Grouse Index is the Council's newest biological indicator of Connecticutís environmental health. Ruffed Grouse is one of many species that live in a combination of habitat types. This edition contains a new section called Mosaic Habitats, where the reader will find trends in wildlife species that rely on more than a single type of habitat. Many turtles, for example, depend on an unbroken network of forests, fields and clean streams. The trends for the species in this category are not encouraging.
A new chart tracking consumption of gasoline and diesel fuel in the state was added to the report. This chart was added to the June 2016 update of last year's report, when transportation became the nation's largest source of greenhouse gases, outpacing even power generation.
One Personal Impact indicator was discontinued this year. Previous reports displayed the number of households who elected to purchase
electricity from renewable sources (principally wind) through a surcharge on their bills. That program was discontinued in late 2016.
A note about charts: This report employs a few conventions to make sure the data are displayed in an unbiased way. One of these is to begin every vertical axis at zero. In a few cases, however, this results in a chart that is not readable. Charts with a shortened vertical axis now include the phrase "detailed view" in the title.
