Should Wolves be Reintroduced in Colorado?

If wolves were reintroduced in our state, would they benefit the environment or be a nuisance for ranchers? In spite of a 2016 resolution passed by Colorado Parks and Wildlife stating that wolves would not be purposefully reintroduced into the state (although those that wander here on their own won’t be removed), the debate continues.

Time Machine Tuesday: The Colorado Conservation Commission

“It is also vandalism wantonly to destroy or to permit the destruction of what is beautiful in nature, whether it be a cliff, a forest, or a species of mammal or bird. Here in the United States we turn our rivers and streams into sewers and dumping-grounds, we pollute the air, we destroy forests, and […]

Don't Release Non-Native Species into the Wild

Have you ever seen a tropical bird flying around Denver, or caught a strange-looking fish in a mountain stream?  It happens — but it shouldn’t.  Sometimes people think releasing an animal back into the wild is a kind way of letting it go free — but this is far from the truth.  In fact, when […]

Tamarisk

The tamarisk plant (saltcedar) is one of the greatest threats to riparian habitats and streams. Originally from Eurasia, it was introduced in the 1800’s to the southwestern area of our country. For years I’ve seen it along the western rivers. Now I see it in the metro area along roadside marshes, drainage ditches, foothills streams, […]
