Results of a biodiversity count held a few weeks back at Ojibway Park are in.
Volunteers took a "biological inventory" over 24 hours.
In all, more than 100 volunteers counted 1,000 species.
Of those 1,000, nine had never been documented in Canada and two were new to the, organizers said.
Tom Preney organized the event, which had experts and volunteers scouring the woods and prairie.
He told CBC's The Bridge host Bob Steele that seven of the previously undocumented finds were types of spiders.
"They take a lot of time to be able to identify. We didn't know we discovered them that day, it wasn't until about two weeks after when we went back to the lab and looked underneath a microscope and started identifying these things," he said. "Then there was seven of them that we couldn't match up."
Another find highlighted by the organizers was the discovery of an endangered species new to Essex County
The spotted winter green is a plant that was previously known in only two sites in Ontario, Norfolk and Niagara County.
