Local History of Chaffee County Major Forest Health Issues Forest
Local History of Chaffee County Major Forest Health Issues Forest Ecology Recent Large Fires Early settlers/homesteaders: Subsistence Homesteaders in the Arkansas Valley and out west harvested a lot of trees to build and heat their homes. Sawmills also were in the area and they milled logs into lumber that was used to build homes. Railroad logging: right-of-ways, ties, bridges, & charcoal The Denver and Rio Grande Railroad Company set up shop in Salida and essentially built the town. There were several different rail lines in the county but a lot of them no longer exists. The boat ramp in Salida was the monarch spur rail line 25% of U.S. lumber consumption went to railroads (approx. 20 million acres of forest 1850-1910) Much of our forests were harvested. A lot of the trees today are less than 150 years old. There are still places along the river and in the county where you can find the older trees. 350,000 miles of track @ 2,500 ties/mile (needed replacing every 5-7 years, too) Mining Timbers Gold and silver mining was very active in Chaffee County. Up Chalk Creek is the town of Saint Elmo which was the center of the mining district. Mary Murphy mine is between Hancock and Saint Elmo. By 1881 the mine had become the largest ore producer in the Chalk Creek area yielding on average $12,000 per day. Charcoal for iron smelters Salida had its own smelter which cost about 1 million dollars to construct and employed 300 men. On October 25 1902 the first furnace of 6 furnaces started. In 1903 it processed over 1 million dollars worth of ore which yielded gold, silver, lead, and copper. It ran for less than 20 years. One stack remains as a historic site. Smeltertown Roundhouse in Salida The round house was used to service and repair engines. It was one of the largest round house between Salt Lake City and Denver. The roundhouse was located where Calco is today (the old building down river left below F street). Fire destroyed 17 locomotives in the roundhouse & shops Dec. 11th 1892 Rio Grande Railroad Station The Denver and Rio Grande remained strong into the 1920s, but tough economic conditions among farmers and on the Great Plains , with the Great Depression, and the Dust Bowls of the 1930s and 1950s weakened the company. The last freight train from Pueblo via, Salida, Brown’s Canyon , Nathrop, Leadville and over Tennessee Pass ran Sunday, August 23rd 1997. The last passenger train was 1964. Insect Forest Health Update For 2013, the spruce beetle remained the dominant insect threat for Colorado’s forests. The spruce beetle has impacted nearly 400,000 acres statewide. Thousands of Acres Infested 1200 1000 Mountain Pine Beetle Spruce Beetle 800 600 400 200 0 Year Between 70 and 90 percent of Engelmann spruce trees in the San Juan Mountains have been killed by spruce beetles, which is evidenced by the gray trees. It remains to be seen what toll the spruce beetle will take in the Arkansas Valley. Lecture 5: Emerging Voices for Conservation Slide: 13 / 42 Although on the decline, mountain pine beetle has impacted more than 3.4 million acres in Colorado since the current epidemic began in 1996. Mountain pine beetle is not a problem in the Arkansas Valley. Most of the epidemic occurred in northern and northeastern Colorado. I Lecture 5: Emerging Voices for Conservation Slide: 14 / 42 Emerald ash borer was detected in Boulder County in September 2013. Approximately 20 percent of all trees on Colorado’s Front Range are ash trees. Lecture 5: Emerging Voices for Conservation Slide: 15 / 42 Piñon Pine Ecology • 5,200 – 9,000 feet in elevation • Adapted to drought and cold • Easily killed by fire due to thin bark • Flammable foliage • Dead lower branches will accumulate • Dense forests • Intense wind driven wildfires! Ponderosa Pine Fire Ecology • 5,000 – 9,000 feet in elevation • • • • • • Resistant to wildfire Open tree crowns Thick, insulating bark on mature trees Self-pruning branches Home to Abert squirrels Adapted to frequent, low-intensity ground fires to reduce competition • Elevation range grow near river banks in riparian areas • ires Black Forest Fire Colorado Springs Over grown Forest need to be thinned so a fire can have beneficial effects and the fire is not followed by a flood. Black Forest Fire Black Forest Fire Managed Forest Unmanaged Forest Waldo Canyon Fire 345 Homes Lost in 4 hours The Waldo Canyon destroyed the most homes of any wildland fire in Colorado’s history. The fire was located on the west side of Colorado Springs. Damon Lange District Forester Colorado State Forest Service 719-539-2579 Damon.Lange@colostate.edu http://csfs.colostate.edu/
