Destructive Tree Pest Detected in Colorado (Sep 27, 2013)
Colorado Department of Food and Agriculture.
An invasive insect responsible for the death or decline of tens of millions of ash trees in 21 states has been detected in Colorado for the first time.
A suspect tree was spotted in Boulder County on September 23rd by City of Boulder Forestry staff. Insect specimens from the ash tree were collected and sent to the United States Department of Agriculture (USDA) Systematic Entomology Laboratory where the identity of the insects was confirmed. "The confirmation of these specimens as emerald ash borer (EAB) marks the western-most occurrence of this invasive pest in North America," said Patrick McPherren, USDA State Plant Health Director in Colorado. "To date Colorado is the fourth State to detect EAB in 2013."

Colorado State University. Colorado State Forest Service. The Colorado State Forest Service is in the process of monitoring the state's black walnut trees for thousand cankers disease - a relatively new disease to the state that is lethal to infested trees. After being introduced to Colorado in recent years, the disease has already caused significant tree mortality in many of the state's urban forests, primarily along the Front Range from Fort Collins to Pueblo.
Mandatory Inspections in Effect

State wildlife officials first discovered New
Zealand mudsnails in South Boulder Creek in 2004 and are taking action to
prevent them from spreading. The New Zealand mudsnail competes with native invertebrate
species and can destroy forage important to trout and other native fishes. Learn
more how to identify the New Zealand Mudsnails, how to stop the spread and
how to report sightings.
Crayfish -- learn how to identify,

Division of Wildlife.
The Colorado Division of Wildlife is monitoring
the state's waters for the introduction
of an aggressive invasive species, the rusty
crayfish. Rusty crayfish were found for
the first time in Colorado during routine sampling
operations in 2009 in the Yampa River drainage
between Steamboat Springs and the town of Yampa.
Because of their larger size and more aggressive
nature, rusty crayfish can impact fish populations
by consuming small fish and fish eggs, and
negatively impact fish and spread unwanted
aquatic plants by aggressively harvesting underwater
plant beds. Learn more how to identify the
rusty crayfish, how to stop the spread and
how to report sightings.
