1 Penobscot River Habitat Focus Area 2016 Annual Report The Penobscot River is New England’s second largest river, draining nearly one-third of the state of Maine with a watershed area of 8,570 square miles not including tributaries to Penobscot Bay. The watershed is home to 11 migratory fish species, including three listed under the Endangered Species Act, and represents the largest run of Atlantic salmon in the United States. It has a rich cultural history of commercial, recreational, and sustenance fishing. It is also home to the Penobscot Indian Nation and includes the Katahdin Woods and Waters National Monument. The …

Scatter hoarding by corvids (crows, jays, magpies, and nutcrackers) provides seed dispersal for many large-seeded plants, including oaks and pines. When hoarding seeds, corvids often choose nonrandom locations throughout the landscape, resulting in differential survival of seeds. In the context of habitat restoration, such disproportional storing of seeds in areas suitable for germination and establishment can accelerate expansion and recovery of large-seeded tree populations and their associated ecosystems. Here, we investigate the spatial preferences of island scrub jays Aphelocoma insularis during scatter hoarding of acorns (Quercus spp.) on Santa Cruz Island. We use a large behavioral data set on …
