Mountain Pine Beetle from UC Boulder

MOUNTAIN PINE BEETLE INFESTATION 2026

MPB & Galleries - Colorado State Forest Service-CSU

The Mountain pine beetle (Dendroctonus ponderosae) is back in Jefferson County. This little bug, this native to the western North American pine forests, is responsible for the periodic loss of millions of pine trees – most normally Ponderosa, Lodgepole, Scotch and Limber pines.

Mountain pine beetles (MPB) are always with us, having evolved with the western pine forests. Under ideal conditions, their attacks are low-level, limited to trees that have been stressed due to injuries, drought, over-crowding, fire damage, root disease or old age. However, every 10-30 years, whether due to beetle population explosions, enhanced drought, or warmer temperatures (or all three), major outbreaks occur.  The last major MPB outbreak in Jeffco occurred from 1996 to 2004. Since 2023 there have been signs of a new resurgence of MPB in our area.

UPDATE 11/20/2025: The trailhead formerly known as the “as yet to be named trailhead” now has a name. The CCR (Colorado Central Railroad) Trailhead was the site of a grand opening ceremony for the eastern 1.25 miles of the Huntsman Segment on this day.

An engineering miracle on Jeffco Parks & Open Space land is nearing completion in Clear Creek Canyon along U.S. 6. Just beyond Tunnel One, the new segment of the Peaks to Plains Trail is expected to partially open before the end of 2025.  This is a moment that Open Space has been planning for years.

Currently under construction is a 3-mile concrete trail deep inside one of the least forgiving passages along the rugged river’s granite gorge. Read more

Why Use Conservation Easements

Alpine Sunflowers in the High Country - Centennial Cone OS Park

By Don Moore, PLAN Jeffco Board Member

An important tool in the toolbox to preserve open lands and natural landscapes is the use of conservation easements. Conservation easements have been increasingly gaining favor in recent years as a means to preserve wildlife habitat and agriculture lands, and to protect scenic views, lands for recreation, and lands of significant ecological, historic, or cultural value.

Conservation Easements Preserve Open Lands, Protect Wildlife

Furred, feathered & finned critters that are protected by conservation easementsIn 1971, Carol Karlin conceived of the idea of buying large swaths of scenic mountain property to protect it from development and build trails for public recreation. Shortly thereafter, PLAN Jeffco was formed, and months later, the Jeffco Open Space program was voted into reality. Read the full story here.

Since that time, nearly 58,000 acres have been purchased by Jeffco Open Space, lands that have become Open Space Parks and that have been incorporated into local city and park & recreation district trails and playgrounds. But purchasing lands is not the only way to preserve open space.

Conservation easements, voluntary, legal agreements that permanently limit uses of the land in order to protect its conservation values, are instruments that have protected and preserved some 2.7 million acres in Colorado alone, a number that represents over 6% of private lands in the State.

Remembering the Founders – Carol Karlin

The Woman of the Living Room Legacy

By Vicky Gits and Bette Seeland

Karlin is credited with launching PLAN Jeffco and the open space movement in 1971 from her Lakewood living room along with a gathering of members of the League of Women Voters and others.

Without the vision and genius of Carol Karlin the Jefferson County Open Space system might never have become reality.

Thanks to Karlin’s idea of scooping up cheap acreage for posterity, the Front Range enjoys a generous portfolio of trails and parks owned and maintained in perpetuity by the residents of and visitors to Jefferson County who pay a half-cent sales tax.

This explains why there is a charming outdoor seating nook framed in pinon and boulders in a distant corner of Elk Meadow Park in Evergreen. Established sometime around 2008, the site is marked with the sign that says, “Carol Karlin Overlook.” Read more

Mount Tom is Conserved!

On Tuesday, April 11th, 2023, a joint effort between Jeffco Open Space, The Conservation Fund, Colorado Parks & Wildlife, and Great Outdoors Colorado came to fruition with the conservation of some 2,000 acres within the Mount Tom Conservation Corridor area. This swath of land is located adjacent to the Ralston Creek State Wildlife Area, northwest of Denver and Golden.

The Mount Tom Conservation Corridor is comprised of fee-owned and conservation easements. It connects to other previously conserved areas, extending in a landscape-wide manner the natural resources for wildlife and Colorado communities while protecting floral and faunal species of special concern, as well as endangered species that live in this area, plus a critical watershed, the headwaters of Van Bibber Creek, a tributary of the South Platte River. The area is not yet open to the public, but following intensive monitoring, investigation and inventory of the future preserve, access for outdoor recreation for the publicly-owned sections are planned.

To read the entire press release, go to the JCOS News Flash here.

Another success for land acquisition!  Let’s hear it for this quorum of conservation organizations — many thanks to all the fine folk who worked so long and so hard to make this happen.

Conservation Smart Brief 11/17/2022

PLAN Jeffco started with an idea that open spaces are vitally important to the health and welfare of all, and since 1972 has been building on that idea. Time brings change, and so PLAN Jeffco has had to consistently adjust as change occurs. 

PLAN Jeffco tries to keep its thumb on the pulse of the conservation community. Every month, as part of our regular Board meetings, there’s a “President’s Report”, which records the activities of various conservation groups that PLAN Jeffco feels are community leaders. We’ve decided to share as much of this information with you, dear reader, as we can, so that you can understand where we’re going, and why.

Colorado Open Lands

Arkansas River Community Preserve in southern Lake County adds 100 acres, thanks to a decade-plus collaboration between Central Colorado Conservancy, Lake County, Colorado Open Lands, funders and other partners.  The ARC Preserve protects important wetlands and wildlife habitat for bighorn sheep, elk, beaver, and many bird species. The public will be able to access the area in about a year to hike, fish, and more.

Big Country Ranch, 698 acres in Grand County, connects a portion of Arapahoe National Forest to large swaths of Bureau of Land Management (BLM) land and other private conservation easements. The property is a known winter range for elk, and habitat for Columbian Sharp-tailed grouse, bighorn sheep, black bear, pronghorn, mule deer, and numerous songbirds, raptors, small mammals, amphibians and lizards.  Wetlands and several small ponds and a reservoir provide additional habitat value. The water rights are tied to the land with the easement as well. The Grand County Open Space, Rivers, and Trails program was a project partner.

Big Bend Pasture, located in the upper Tomichi Creek Valley, east of the City of Gunnison, is part of the Irby Ranch cattle and hay operation. The property, which provides summer and fall grazing ground for the family’s cattle, consists of irrigated meadows, sagebrush shrublands, subalpine forest, and ¾-mile of frontage along Big Bend Creek and 1.75 miles of frontage along Marshall Creek. The property is habitat for bald eagle, ferruginous hawk, greater sandhill crane, northern leopard frog, bighorn sheep, black bear, elk, moose, mountain lion and mule deer. It was the largest previously unprotected private property in the Marshall Creek drainage. This project was completed in partnership with Trust for Public Land.

November 2, 2022: MALT has closed on a conservation easement in Boulder County. This 12-acre property is located west of Boulder, along Sunshine Canyon Drive. This CE is a connector between Boulder County Open Space and BLM lands. It ensures that scenic views of the Bighorn Mountain Natural Landmark are permanently protected, and is recognized by Colorado Parks and Wildlife as habitat for many large mammals, including mule deer, elk, black bear and mountain lion.

November 4, 2022: MALT, Keep It Colorado and Park County Land and Water Trust Fund have joined forces to enable the Sacramento Preserve Conservation Easement, 56.5-acres in Park County near the town of Fairplay. This area features a rich riparian and wetlands habitat, beaver ponds, wildlife and a small cabin. The owners, Tri-Walk LLC, Lynn Grams and Christine Smith, wish to preserve their families’ legacy with this Conservation Easement.
