For more than 60 years, the Colorado State Forest Service (CSFS) has been living out its mission: To achieve stewardship of Colorado’s diverse forest environments for the benefit of present and future generations. This is made possible not only by actions within the forestlands of Colorado, but also by initiating face-to-face conversations with surrounding community members, landowners and other agencies. Areas in which the CSFS offers leadership and guidance include forest management; wildfire mitigation and community planning; wood utilization CSFS Community Forestry Program Manager Keith Wood teaches an urban and and marketing; outreach and education; community forestry workshop, with Boyd Lebeda, CSFS Fort Collins District and insect and disease detection, forester.

The agency offers technical assistance in urban and community forestry, including tree care and management plans, and is Colorado’s primary provider of seedling trees for conservation purposes such as creating living snow fences and windbreaks, reforesting areas after wildfire and enhancing wildlife habitat. The CSFS works through 19 district and field offices statewide, with a headquarters located in Fort Collins. The agency operates within the Warner College of Natural Resources at Colorado State University and fulfills the responsibilities of the Division of Forestry within the Colorado Department of Natural Resources.

Fire and Water 1 Executive Summary Annual reports on the health of Colorado’s forests provide information to the Colorado General Assembly, stakeholders and citizens by summarizing the current health and condition of forests across the state. This year’s report offers a special focus on how forests impact and are conversely affected by wildland fire and water flowing through forested watersheds. Between broader sections on fire and water, the report offers a detailed review of 2016 insect and disease activity in Colorado forests. Colorado’s 24.4 million acres of forestland provide immeasurable social, economic and ecological benefits to its citizens and visitors. Forests offer a sustainable wood products industry, diverse wildlife, fresh water and ample recreation opportunities. But they face numerous threats, and can present risks to citizens and visitors.

The same Colorado forests impacted by insects, disease and wildfire provide sustainable water supplies – one of the most critical resources throughout the West. Nineteen states and Mexico derive water from Colorado’s high-country watersheds, utilized by entities ranging from municipalities, industries and agriculture to fish and wildlife. But here and in other Western states, unhealthy and overly dense forests set the stage for exceptionally large, devastating wildfires that significantly increase risks for dangerous flooding, extreme erosion, degraded water quality and reduced water storage capacity. CSFS foresters work with land managers and private landowners to accomplish effective forestry practices and reduce the risk of severe wildfire and post-fire flooding.

Photo: Beaver Creek Incident Management Teams 4 2016 Report on the Health of Colorado’s Forests Implications for Fire Suppression and Forest Management Consider how a campfire is properly built: first with kindling, then by adding small branches and larger logs. This is because fires ignite quickly in smaller fuels, while the larger wood ultimately burns longer and puts out more heat. Fuel in the form of kindling and small branches also burns quickly without much smoke; however, the larger logs in a campfire burn and smoke for much longer, even well after the flames die out. Now, imagine a campfire that encompasses 3.4 million acres, or the area impacted by MPB in Colorado. During 2016’s Beaver Creek Fire, which burned 38,380 acres northwest of Walden, foresters and firefighters were given a glimpse into likely future challenges facing wildfire suppression and forest management efforts.

Wildfire Smoke and Public Health

An increase in the size and intensity of wildfires, paired with increased population density in and near Colorado’s wildland-urban interface (WUI), has led to a high potential for wildfire smoke to impact larger populations. Smoke from wildfires is a mixture of gases and fine particles from burning trees and vegetation, which can cause stinging eyes and irritated respiratory systems. Risks are higher for those with chronic heart and lung diseases, and for children and the elderly. A century of intensive fire suppression has led to a public expectation of a smoke-free environment. However, due to Colorado’s current forest conditions, it is a matter of when, and not if, a large wildfire will occur. Wildfire mitigation and forest management focused on reducing the build-up of fuels is essential to help create healthier forests and decrease the risk of smoke impacts to public health resulting from large, catastrophic wildfires. Prescribed fire also is an effective means to reduce hazardous fuels, and to reintroduce fire into naturally dependent ecosystems. The amount of smoke produced from prescribed fires is typically minimal compared to the amount

CWPP Helps Firefighters Manage Beaver Creek Fire

Detailed information in the Jackson County Community Wildfire Protection Plan (CWPP) played a large role in helping wildland firefighters plan and prepare for the 2016 Beaver Creek Fire. At the onset of the fire, the CWPP and the Jackson County Firefighter Response Guide, created by the CSFS Steamboat Springs District, contained the best available information for incident responders and helped influence the development of further GIS information to utilize throughout the wildfire’s duration. The Firefighter Response Guide was updated as a component of the Jackson County CWPP process, to better inform first responders of access issues, local terrains, potential hazards and possible evacuation routes and plans throughout the county. This information was utilized by the local fire district at the onset of the Beaver Creek Fire to plan its incident response tactics. The county’s CWPP itself outlined critical infrastructure, as well as community values requiring protection. This Firefighters at work on the Beaver Creek Fire in 2016.

WRRG Success Story: Keene Ranch

Dawson Butte Open Space is a 1,028-acre recreation area in Douglas County that adjoins the Keene Ranch subdivision. The subdivision is made up of 247 lots that range in size from 5 to 35 acres, and the primary vegetation type is Gambel oak, which resprouts vigorously after treatments. Due to concerns of fire starting on the publicly utilized open space and moving into the community, or vice-versa, Douglas County received funding through the WRRG Program in 2013 to treat 134 acres. The Colorado State Forest Service did the layout and project administration, which included creating firebreaks in Gambel oak within the community boundary and reducing hazardous fuels in adjoining ponderosa pine and Douglas-fir forests. Keene Ranch received another grant in 2014 and treated 327 acres over two years on 74 properties, which included treating the trail system in the open space along the community boundary. Landowners are currently maintaining these treatments every other year, which is essential to maintain treatment effectiveness. Douglas County also received funding in 2015 for additional work on the Dawson Butte property to improve forest health and reduce fire hazard.

Douglas-fir Beetle (Dendroctonus pseudotsugae) Douglas-fir beetle, another close relative of spruce beetle and mountain pine beetle, is an important native bark beetle of Douglas-fir forests across most of the West. Outbreaks tend to be associated with mature Douglas-fir forests coupled with periods of below-normal precipitation. Adults typically seek new trees to attack from May through September.

Adult beetles typically fly to seek new trees within which to lay eggs under the bark in summer, with the peak in July and August. Tree mortality occurred in 2016 in southern Colorado where white fir grows in mixed-conifer forests, often near Douglas-fir. Localized areas affected included the Sangre de Cristo Mountains south to the northern portions of the Culebra Range. The eastern slopes of the Wet Mountains continued to experience mortality, ranging from individual tree deaths to pockets of 10 or more trees impacted. Infestations near the mountain town of Ouray continued to impact the few remaining white firs in the area for the fourth straight year, where this beetle is estimated to have killed more than 85 percent of the white fir in the Uncompahgre River Gorge surrounding the town. • 2016 Acres Impacted: 6,300 • Notable Counties Impacted: Archuleta, Ouray Western Spruce Budworm (Choristoneura freemani) Larvae of the native western spruce budworm feed in buds and on new shoots of Douglas-fir, true firsAbies ( spp.) and Engelmann spruce.

Exotic Pests A Changing Climate Could Increase Bark Beetle, The introduction and establishment of exotic and potentially invasive insects, Wildfire Risks fungi, plants and other organisms threatens forests worldwide. Invasive insect species can cause severe damage in their new habitats, because their new host trees may have little or no resistance to the introduced pest, and natural enemies (i.e., predators and parasites) of the pest are not present in the new habitat to help keep populations in check. Once established, invasive tree pests can be spread over long distances via the human transport of firewood, nursery stock and other plant materials. Exotic, invasive insects and diseases pose a threat to both native and urban forests in Colorado.

Warmer and drier central and northeastern United States conditions in the past few decades already have contributed to the largest bark and Canada. It is now considered the beetle outbreaks in the state’s recorded history, as well as the top 10 largest fires all occurring since 2002. Further warming of between 2.5°F and 6.5°F is expected in Colorado by 2050, according to climate model projections. Earlier springs and hotter summers are anticipated throughout the state, reducing Colorado’s spring snowpack levels and causing earlier melting and runoff. Most climate projections indicate that droughts, wildfires and heat waves all will increase in frequency and severity in Colorado by the middle of this century. One of the best defenses against threats associated with a changing climate is to ensure diverse, resilient forest ecosystems. Forests – including those in Colorado – play a critical role in society’s ability to deal with climate change because trees in healthy forests store and absorb carbon that might otherwise end up in the atmosphere. Young and vigorously growing forests absorb the most carbon dioxide, while dead or burned trees conversely release this greenhouse gas back into the atmosphere. The CSFS helps landowners face the impacts of a changing climate by supporting ongoing forest management to increase forest resiliency and reduce the risk for catastrophic wildfire. As forest conditions change in response to climate shifts, the CSFS can help landowners manage forest composition, stand density and the fuels available for wildfire, while improving resistance to insects and disease.

Best Management Practices Help Protect Water Supplies

The Colorado State Forest Service (CSFS) helps address the risk of nonpoint source pollution to water supplies by providing Forestry Best Management Practices (BMPs) for Colorado. These are guidelines that help forest landowners, land management agencies and the timber industry to protect water supplies and avoid inadvertently polluting them. Federal land management agencies subscribe to these practices, but they are voluntary on private lands in Colorado. Biennially since 2008, the CSFS, in cooperation with researchers and other state and federal agencies, has monitored the application A recently completed forest and fuels management and effectiveness of forestry BMPs through audits and field project on the Pikes Peak Watershed, visible from monitoring. Audit results foster adaptive changes to BMP guidelines Lake Moraine, El Paso County.

And when heavy precipitation and resulting runoff bring post-fire sediment, ash or debris into streams or treatment facilities, drinking water treatment becomes difficult, if not impossible. Due to a variety of factors – including tree mortality caused by the mountain pine beetle epidemic, years of drought and the build-up of fuels in the forested landscape – watersheds on the West and East slopes are becoming more susceptible to high-intensity wildfires that could create poor water quality conditions. The active 2012 fire season served as a wake-up call to water suppliers in northern Colorado, emphasizing that watershed health is paramount to delivering clean, reliable water to customers. This, along with other Colorado water suppliers’ experiences responding to wildfire and forest health planning, led to the formation of the Colorado-Big Thompson (C- BT) Headwaters Partnership between the Northern Water Conservancy A stream near Vail.
