Book Description
Tracks recent environ. changes throughout the Arctic. In 2010, it is clear that the Arctic is experiencing the impacts of a prolonged and amplified warming trend, highlighted with many record-setting events. The impact of this warming is most evident in the dramatic losses that have been observed in the ice covers that define the region. Since the loss of these ice covers serves to further feed the warming trend, the expectation is that warming will continue. This makes it increasingly unlikely that the Arctic will return to conditions that were considered normal in the later part of the 20th cent. Instead, it is very likely that Arctic climate warming will continue and records will continue to be set in years to come. Charts and tables. This is a print on demand report.

Abundance Index of St. Lawrence Estuary Beluga, Delphinapterus Leucas, from Aerial Visual Surveys Flown in August 2014 and an Update on Reported Deaths

Book Description
“The beluga is an Arctic species, and the St. Lawrence Estuary (SLE) population is at the southernmost limit of the species distribution. Up until 2007, the population appeared to be stable. However, unusually high numbers of young of the year found dead in 2008 and 2012, and a low aerial photographic estimate of abundance in 2009, triggered a review of the population status in 2013. Based largely on this review, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) re-evaluated the status of SLE beluga in 2014, and recommended that the population be designated as ‘Endangered’ (COSEWIC 2014). Here, we present a new abundance index of SLE beluga from a series of eight visual aerial systematic line-transect surveys flown in August and September 2014. This will be used to evaluate trends in abundance along with the 36 visual surveys completed with similar methods since 2001. We also present an update on the number of beluga carcasses that have been recovered since the last assessment (DFO 2014)"--Introd., p. 1, 2.

Book Description
This document reviews the current state of knowledge about St. Lawrence belugas, recommends a series of actions for ensuring their survival and proposes an implementation schedule. The goal of the Recovery Plan is to bring population numbers and conditions to a state where natural event and human activities will not threaten the survival of the St. Lawrence beluga whale population. A subsidiary goal is to improve the status from endangered to vulnerable, as defined by COSEWIC.
