Putting Invasive Species on the Map
"To have a fighting chance at controlling them, we have to know where they are and how many of them there are," says Jim Gores speaking about Oregon 's invasive species. As ODFW's Invasive Species and Wildlife Integrity Coordinator, Jim is currently walking the walk as he travels around the state, working with district biologists to create a map of invasive species infestations in Oregon . Species being mapped include nutria; opossum; feral populations of swine, goat and sheep; bullfrogs; crayfish; and goldfish. Fallow, axis and sitka deer that have escaped from captivity are also being mapped.
The goal is to put this information into a Geographic Information System (GIS) and Web-friendly format that can be shared with partners and overlaid onto the Strategy's Conservation Opportunity Areas map. Oregonians can then see what control and eradication projects are needed in their area.
Some of Jim's initial findings include:
Feral swine are not nearly as prevalent in Oregon as believed, which means we have a good chance of keeping them from spreading-and maybe even eradicate them.
Nutria are thick throughout the Willamette Valley and are beginning to spread south to Roseburg and Medford .
Feral sheep, goats, and escaped fallow, axis and sitka deer are emerging as a significant threat to wildlife habitat in Oregon .
