People are learning how to take better care of an important watershed near Missoula.

Tonight, kids and adults got help figuring out what weeds choke out the natural plants and fish in Greenough Park.

Many speakers also taught families about things like bark beetles, bear, plants and the history of the critical watershed.

Steve Randall of the Rattlesnake Creek Watershed Group tells NBC Montana, "There is never enough information. You have people coming in not even knowing the history of Greenough, but as you get people coming in and learning the history of the plants, people appreciate it more. They take better care of it. They will be better stewards of it."

Rattlesnake creek is important for a lot of wildlife. For Example, group members say it's one of only four main waterways in our area where bull trout spawn. Bull trout are a threatened species.
