No warnings for fireworks’ violators; police will issue tickets (for real)
Jun 22nd
But they still have to catch you in the act
For the second year in a row, Boulder police are announcing a zero-tolerance policy for fireworks violations. It’s illegal to possess or explode fireworks within city limits and violators will be cited — or possibly arrested — depending on the offense. Anyone starting a fire while using fireworks could face additional arson charges.
Fire danger is very high in Colorado, as we have seen recently with the multiple wildfires burning around the state, and Boulder Police Chief Mark Beckner says he is concerned about protecting residents. “We are taking a cautious approach again this year, because we want everyone to be safe. Fireworks can be dangerous, and this kind of “fun” can turn into an emergency very quickly,” said Beckner. “Because our focus is community safety, the Boulder Police Department will not tolerate fireworks violations.”
Residents will notice increased patrols leading up to the holiday and on July 4th; extra officers will staff Chautauqua Park, Boulder Reservoir and Folsom Field. The Boulder Fire-Rescue Department is currently conducting additional “severity patrols” on the outskirts of the city, and extra firefighters will be on duty during the fireworks show at Folsom Field.
“Given our recent weather patterns, we know it’s going to be another hot, dry summer,” said Boulder Fire-Rescue Chief Larry Donner. “People should understand that they don’t need to live in a forest to experience a disastrous fire. We want everyone to remember the holiday as a celebration, rather than as a marker for a tragedy.”
Police are asking the public for assistance: anyone who sees a fireworks violation is asked to report it immediately to Boulder police. Officers need the location of the violation and descriptions of the people involved.
The non-emergency number for Dispatch is 303-441-3333. Please call 9-1-1 if there is an emergency or a fire.

Community Forestry Sort Yards to open in May
Mar 20th
“Spring is a great time of year to get out on your land and begin preparing your property for wildfires.”
Boulder County, Colo. – The Boulder County Forest Health Initiative is pleased to announce the Community Forestry Sort Yard operating schedule for 2013. Two sort yard locations are open each summer to provide residents a free of charge location to dispose of logs and slash cut from their land.
The sort yards do not accept yard clippings, raked up pine needles, root balls, construction materials, dirt, furniture, household trash or wood with metal in it. Sort yard staff will refuse loads that contain unacceptable items.
Allenspark/Meeker Park Sort Yard
- Spring hours: Fridays and Saturdays from 9 a.m. to 5 p.m. May 24th thru June 15th
- Summer/Fall hours: Tuesday thru Saturday 9 a.m. to 5 p.m. July 30th thru Oct. 19th
Nederland Area Sort Yard
- Spring hours: Tuesday thru Saturday from 9 a.m. to 5 p.m. May 1st thru July 6th (closed July 4th)
- Summer/Fall hours: Fridays and Saturdays from 9 a.m. to 5 p.m. Sept. 20th thru Oct. 12th (these dates are tentative)
The Community Forestry Sort Yards may have additional closures during the open season due to weather, staff training or other administrative requirements. To check the operational status of a sort yard please call 303-678-6368.
Boulder County encourages all of its residents to be good stewards of their backyard forest and to implement effective wildfire mitigation on their land.
“The spring is a great time of year to get out on your land and begin preparing your property for wildfires,” said Ryan Ludlow outreach forester with the county’s Land Use Department. “Simple actions like picking up downed branches, raking away all pine needles within 5 feet of your structures, cutting tall dead grass and moving leftover winter firewood piles off of porches and placing them at least 30 feet away from the home can really help improve the chances of your home surviving the next wildfire.”
If you want to learn more about how to implement effective wildfire mitigation on your land join us at the Nederland Community Center on May 11 for a half day workshop focused on “Firewise Landscaping.” Learn how to transform your home’s perimeter into an area that you can not only use, but also looks good and helps protect your home from wildfire.
For more information about the sort yard program or how to implement proactive wildfire mitigation on your land, contact Ryan Ludlow, Boulder County Forest Health Initiative’s outreach forester, at 720-564-2641 orrludlow@bouldercounty.org.

CU researchers: Beetle killed trees are better than logging for watersheds
Jan 14th
buffers watersheds from nitrate pollution
A research team involving several scientists from the University of Colorado Boulder has found an unexpected silver lining in the devastating pine beetle outbreaks ravaging the West: Such events do not harm water quality in adjacent streams as scientists had previously believed.
According to CU-Boulder team member Professor William Lewis, the new study shows that smaller trees and other vegetation that survive pine beetle invasions along waterways increase their uptake of nitrate, a common disturbance-related pollutant. While logging or damaging storms can drive stream nitrate concentrations up by 400 percent for multiple years, the team found no significant increase in the nitrate concentrations following extensive pine beetle tree mortality in a number of Colorado study areas.
“We found that the beetles do not disturb watersheds in the same way as logging and severe storms,” said Lewis, interim director of CU’s Cooperative Institute for Research in Environmental Sciences. “They leave behind smaller trees and other understory vegetation, which compensate for the loss of larger pine trees by taking up additional nitrate from the system. Beetle-kill conditions are a good benchmark for the protection of sub-canopy vegetation to preserve water quality during forest management activities.”
A paper on the subject was published in the Jan. 14 issue of the Proceedings of the National Academy of Sciences.
“The U.S. Forest Service and other agencies have established harvesting practices that greatly mitigate damage to forests caused by logging, and they deserve credit for that,” said Lewis. “But this study shows just how important the survival of smaller trees and understory vegetation can be to stream water quality.”
In waterways adjacent to healthy pine forests, concentrations of nitrate is generally far lower than in rivers on the plains in the West like the South Platte, said Lewis. Nitrate pollution is caused by agricultural runoff from populated areas and by permitted discharges of treated effluent from water treatment facilities.
“In Colorado, many watersheds have lost 80 to 90 percent of their tree canopy as a result of the beetle epidemic,” said Lewis, also a faculty member in CU-Boulder’s ecology and evolutionary biology department. “We began to wonder whether the loss of the trees was reducing water quality in the streams. We knew that forestry and water managers were expecting big changes in water quality as a result of the pine beetle outbreak, so we decided to pool our university and federal agency resources in order to come up with an answer.”
Study co-author and CU-Boulder Research Associate James McCutchan of CIRES said the new results should help forest managers develop more effective ways to harvest timber while having the smallest effect possible on downstream ecosystems. “This study shows that at least in some areas, it is possible to remove a large part of the tree biomass from a watershed with a very minimal effect on the stream ecosystem,” he said.
Understory vegetation left intact after beetle outbreaks gains an ecological advantage in terms of survival and growth, since small trees no longer have to compete with large trees and have more access to light, water and nutrients, said McCutchan. Research by study co-author and former CU undergraduate Rachel Ertz showed concentrations of nitrate in the needles of small pines that survived beetle infestations were higher than those in healthy trees outside beetle-killed areas, another indication of how understory vegetation compensates for environmental conditions in beetle kill areas.
The researchers used computer modeling to show that in western forests, such a “compensatory response” provides potent water quality protection against the adverse effects of nitrates only if roughly half of the vegetation survives “overstory” mortality from beetle kill events, which is what occurs normally in such areas, said Lewis.
Other study co-authors included Leigh Cooper, Thomas Detmer and Thomas Veblen from CU-Boulder, John Stednick from Colorado State University, Charles Rhoades from the U.S. Forest Service, Jennifer Briggs and David Clow from the U.S. Geological Survey and Gene Likens of the Cary Institute of Ecosystem Studies in Millbrook, N.Y.
The severe pine beetle epidemic in Colorado and Wyoming forests is part of an unprecedented beetle outbreak that ranges from Mexico to Canada. A November 2012 study by CU-Boulder doctoral student Teresa Chapman showed the 2001-02 drought greatly accelerated the development of the mountain pine beetle epidemic.
The researchers measured stream nitrate concentrations at more than 100 sites in western Colorado containing lodgepole pines with a range of beetle-induced tree damage. The study area included measurements from the Fraser Experimental Forest near Granby, Colo., a 23,000-acre study area established by the USFS in 1937.
The new study was funded by the USFS, the USGS, the National Science Foundation, the National Oceanic and Atmospheric Administration and the National Park Service. CIRES is a joint research institute between CU-Boulder and NOAA.
