Vegetation found in the areas from Clement Bay to Lake 3t. Flerre was 
characteristic throughout, except for the occurrence of wild rice in the 
South River Bird Senctuary, and of flowering rush along the borders of the 
Cid Beavharnois Canal south of Montreal and in Lake St. Fierre. The 
characteristic vegetation consieted of Scirpus americana, Juncus, Sagittaria 
epp-, Seratophyllum, Iypha jetifolia, Utricularia, Vallisneria, Potamogeton 
app., Lemna minor, Lemna trienica, Nymphaea and Polygonum specisa. 



From Troie Rivieres eastward the vegetation underwent @ mador change 
from the preteding types to tidal marshes, dominated by Juneve and Scirpus. 
Hleogharig clumps and Fucus bede were common. . 
| The survey of Ile aux Goudree, where the vegetation consisted chiefly 
of Fucug and Eleocharig, revealed no waterfowl .- 
Tle d'Orleans, of precambrian pranjte and ordovician limestone 
composition, eupported only a few black ducke along the marsh on the northern 
shore of the island. Human activity combined with the lack of mitable food 
prevents any significant nesting population. 
Climatic Conditions 
Water-levele this year appeared normal to slightly lower than normal, 
with normal temperatures and precipitation, ‘Sonditions for nesting and 
erowth of young appeared excellent. ‘ 
The Nesting Season 
The nesting seagon wad well advanced by the time the eaurvey was 
etarted. The first yoing waterfowl were obeerved on Lake St. FPlerra. On 
wune 18th, 14 young black ducke were seen, while on June 20th, 2 pintaila 
and 22 golden-eyes were seen. 
The relative abundance of the different species indicated that the 
black duck wes the principal nester in areas from Clement Bay near Ottawa, 
to Lake St. Pierre, east of Sorel, Quebec, with blue=winged teal, American 
gclden-eye, wood duck, ring-neck and pintall common nesters. ‘Seattered 
individuals of mallards and one ruddy duck were seen. Florida pgallinules 
and pled~billed grebes were also numerous throughout this area. The western 
portion of Lake 5t. Fierre wis the most productive region: a total of 416 
ducks were seen. The South River Bird Sanctuary, the Carillon Island Bird 
Sanctuary and Glement, Lochaber and Black Bays were also good areas, 
The hreeding grounds in the vicinity cf Montreal, including Ile au 
Heron Bird Sanctuary and the Heauharnois Canal region, do not support a 
alenificant waterfowl population, inaufficient food and cover being present 
for auch & purpoge. 
From Quebec Clty eastward, the only epecies of waterfowl seen in the 
tidal marahe#, apart from 1 black duck and 75 surf ecoters wae the American 
elder. Of thie species, 1,738 individuals were seen, of which 191 adult 
femalen had 624 young, giving an averege brood alge of 3.6 ducklinge ver 
brood. Ile Verte, St. Cermaine, Bic, and Rimowski were the chief nesting 
Areas, although the eldere are produced in scattered nunbere along the entire 
coast from St. Anne-de-le-Focatiere eastward.
