“A total of 145 bird species were detected, including nine considered at-risk”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to confirm the species count or at-risk classification
“Vegetation features such as cattails, submerged plants and trees acting as predictors of which species appear at a given pond”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to support or contradict the vegetation prediction claim
“The study found twice the diversity in bird species that was reported in previous studies of urban ponds in southern Ontario”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to compare diversity metrics with previous studies
“The most common were American goldfinches, American robins, red-winged blackbirds and song sparrows”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to verify the species abundance claims
“Nine species classified at-risk in Canada were barn swallows, bobolinks, chimney swifts, eastern meadowlarks, eastern whip-poor-wills, least bitterns, peregrine falcons, yellow-breasted chats and red-headed woodpeckers”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to confirm the at-risk species list
“Stormwater ponds are artificial reservoirs dug in residential areas to mitigate flooding by collecting runoff water that would otherwise flow from storm sewers into streams”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to verify the function of stormwater ponds
“Previous methods of surveying stormwater ponds likely overlooked rare, nocturnal and hard-to-identify species”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to assess previous surveying methods
“Stormwater ponds can accumulate heavy metals, pesticides and improperly discarded liquids like motor oil and solvents”
❓
INSUFFICIENT EVIDENCE
— No evidence found in archive to confirm contaminant accumulation claims
“Contaminants found in ponds move up the food chain – from larval insects to fish to birds like herons and kingfishers”

“Stormwater ponds help restore lost natural components such as streams, ponds, wetlands and wildlife”
❓
PENDING
“The study raises questions about whether stormwater ponds should be managed as habitats for wildlife or not”
❓
PENDING
“Some stormwater ponds may be little more than ponds surrounded by a fence and grass – with none of the other vegetation features that make them conducive to wildlife”
❓
