In January’26, a blog post titled “Mountain Pine Beetle Infestation 2026” appeared in this blog.

Eight months later, sometime toward the end of summer, the Mountain Pine Beetles (MPBs) will have flown. They began their yearly exodus around the middle of June. A day or two after the beetles flew, the females began to burrow under the bark of pine trees – mostly Ponderosa and lodgepole pines in Jefferson County.

WINTER IN THE PARKS – HOW TO STAY SAFE

/0 Comments/in , , , , , /by

Even though it’s only September, there’s no time like the present to post this safety reminder for activity in the parks during the winter months, especially given the extraordinary climate pattern we’re experiencing with the 2026-2027 El Niño.

This article was originally penned back in 2015 by Shaun Howard, who was the Jeffco Open Space Ranger Lead at that time. She wrote this post in an effort to help all Open Space Park visitors understand a little more about how to enjoy winter activities in the Parks.  

Our parks are “primitive” parks. Don’t expect the trails to be groomed for you. Make sure you have micro-spikes with you, just in case you need them. Be prepared for any type of weather, especially as you gain in elevation. Know before you go.

Temps have dropped and winter winds lick the landscape of the Jeffco Parks. Although the winter season has arrived, the parks are still great places to visit. Read on for essential winter safety tips.

Volunteerism isn’t anything new – it’s been around for hundreds if not thousands of years. Officially, volunteerism can be traced back to the 12th century in Britain, where more than 500 hospitals were staffed by volunteers.

The word “volunteer” stems from the Latin voluntarius – “willing, of one’s own free will”. It became part of the English language via Middle French, initially referring to someone who willingly offered themselves for military duty. Today, it has evolved to mean anyone entering service freely, whether military or community service.

Every year, Jeffco Parks & Open Space (JCPOS) hosts a Volunteer Recruitment Fair, during which time folks who are interested in becoming more engaged with our parks can investigate what being a hands-on part of Open Space might be like, i.e. entering service freely. Read more

ENOR group hiking in the park

You’re hiking or cycling in one of our Open Space parks. You encounter a group of kids with a couple of adults, and they seem totally engrossed in a patch of shrubbery. You stop for a moment, you hear children’s voices exclaiming about what they’ve found – they seem so excited about everything around them.

Welcome to ENOR – Eagle’s Nest, Owl’s Roost – Environmental Discovery Camp, which is sponsored by the Jeffco CSU Extension office. ENOR has been in the business of getting kids outdoors for more than 50 years.

Jeffco Parks & Open Space was so impressed with ENOR’s achievements that, in 2024, they presented ENOR with the Gambel Oak Award, as a Pioneer in Environmental Education, at that year’s Conservation Awards Ceremony. Read more

DEAR MISS MOUNTAIN MANNERS – An Advice Column on Multi-Use Trail Etiquette

/0 Comments/in , , , , , /by

In memory of our beloved Board member Bette Seeland, we’re republishing a few of the articles in which she was a major contributor…this is one of them.

Dear Miss Mountain Manners: When I got to my favorite Jeffco Open Space Park for a hike, the parking lot was full. What should I do? Feeling Shutout

Dear Shutout: You could walk close to home instead of driving to a park. Do not park on the road shoulder leading to the park. Download, sign up, then check the LotSpot parking lot app to find a park not currently overcrowded.  Come at a time when the park is less crowded such as weekdays, before 9 am or after 3 pm.

Furred, feathered & finned critters that are protected by conservation easements

Conservation Easements Preserve Open Lands, Protect Wildlife

/0 Comments/in , , , , , , , /by

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.
