List of figures
- Figure 1. Global distribution of belugas (adapted from Reeves, 1990). Belugas are found in the waters of Alaska, Canada, Greenland, Norway, and Russia.
- Figure 2. Location of the seven Canadian beluga populations. 1) St. Lawrence Estuary population; 2) Ungava Bay population; 3) Eastern Hudson Bay population; 4) Western Hudson Bay population; 5) Eastern High Arctic and Baffin Bay population; 6) Cumberland Sound population; 7) Eastern Beaufort Sea population. Adapted from COSEWIC, 2004. In grey is the distribution area and in black are the main summering areas.
- Figure 3. Historic distribution area of the St. Lawrence beluga, adapted from Vladykov, 1944. The area covered in summer extended east along the North Shore to Natashquan and along the south shore to Grande-Vallée. The total distribution area extended to Québec and south of the Gaspé Peninsula.
- Figure 4. Present distribution area of the St. Lawrence beluga, adapted from Michaud, 1993a. The summer distribution area extends from Saint-Jean-Port-Joli to Forestville, including the Saguenay River up to Saint-Fulgence, and the total distribution area extends to Sept-Îles.
- Figure 5. Population estimates for the St. Lawrence beluga from 1988 to 2005, corrected index and standard error (adapted from Gosselin et al., 2007). The population increased slightly, but not statistically significantly, from 900 whales in 1988 to just over 1,200 in 2005.
- Figure 6. Summer distribution of St. Lawrence belugas by herd composition, adapted from Michaud (1993a). Herds of adults with young are found around Île aux Coudres, Îles de Kamouraska, Rivière-du-Loup, and Saint-Siméon. Herds of adults only are found in the Laurentian channel off Les Escoumins. Mixed herds are found in the Saguenay River, the head of the Laurentian channel and southern portion of the estuary. Inset: the location of the sector in Quebec.
- Figure 7. Map of the Saguenay-St. Lawrence Marine Park and the two proposed marine protected areas (MPAs), the proposed Manicouagan marine protected area and the proposed St. Lawrence Estuary Marine Protected Area. Inset: the location of the sector in Quebec.
- Figure 8. Time to meet the population objective of 7070 individuals at the current growth rate of approximately 1% and at the theoretical maximum rate of 4% (M. Hammill, DFO, unpublished data).
- Figure 9. Critical habitat of the St. Lawrence beluga. It extends from the Battures aux Loups Marins to the southern portion of the Estuary, off Saint-Simon. It includes the lower reaches of the Saguenay River. Inset: the location of the sector in Quebec.
