CROWN HILL OPEN SPACE PARK – A BRIEF HISTORY
/0 Comments/in Articles That Educate, Featured, JeffCo Open Space, Parks, Parks & Trails, Uncategorized /by BlogMasterThe land was rich, fertile enough to support wheat fields (Wheat Ridge), fruit orchards (Fruitdale) and further to the north, the farms that would one day become the city of Arvada.
While William worked the farm, Henry traveled on the narrow gauge railroad up Clear Creek Canyon to the mining camps in Gilpin, Clear Creek, and Park counties, selling vegetables to the residents.
In less than 10 years from the time of his arrival, Henry had met and married Jennie Paul, another Iowa ex-pat, and settled down to a married and family life on land that Henry was now farming. Read more

Alderfer/Three Sisters Forest Health 2023-2024
/2 Comments/in Featured, JeffCo Open Space, Parks, Parks & Trails /by BlogMasterManaging and maintaining forest health is incredibly important to the safety of everyone and everything, and so, after 100+ years of the forest overgrowth, JCOS is able to start work on this park.
Starting in August 2023, the JCOS Forest Management Team will remove seedlings, saplings, and even some larger trees – mostly Ponderosa pine and Douglas fir – so that the density of the forest will be reduced. Eventually some 240 acres throughout the entire park will be mitigated. This will result in a healthier ecosystem that will be far more resilient to wildfire than what is currently in place.

Presidents Report 7/31/2023
/0 Comments/in Featured, Presidents Report /by BlogMasterIt’s the merry month of August and President’s Report time, time to catch up with what’s happening in the local land conservation community and spot-checks from around the world. New this month is a section on Signs of Hope. We hope you enjoy the read, and in so doing, we hope this may broaden perspectives in some small way.
– the Fine Folks at PLAN Jeffco
NOTE: in this Presidents Report you’ll read about lands that have been “Permanently Protected” by land organizations. Most of these protected lands have conservation easements on them and have very limited public availability, unlike our Jeffco Open Space Parks.
What is a conservation easement? It’s a promise to the land, a promise that encumbers the land, that protects the land from ever being developed into something other than what it already is. The land is still privately owned, so no — you cannot go trekking across the property without the owners’ permission, but you can rest assured that the land will not sprout condominiums or shopping centers.

/0 Comments/in Featured, Presidents Report /by BlogMasterTowards the end of every PLAN Jeffco Board meeting, there is a Presidents Report. This is our opportunity to bring awareness to issues that transcend our local Jefferson County Open Space Parks. The Presidents Report lists activities and events from local and regional organizations, both land conservancy and otherwise, with reports from national and global news agencies. We hope you enjoy the read, and in so doing, we hope this may broaden perspectives in some small way.

I doubt it. Read more
LEARNING ABOUT THE LAND IN ‘23
/0 Comments/in Featured, Uncategorized /by BlogMasterHow do you describe a day full of learning, a day full of presentations on ecosystems, and the many ways to conserve our natural resources? It was fun. It was engaging. It created an awareness of what is happening in the conservation world and what each of us can do about it.
On the 29th of April, 2023, a room full of open space enthusiasts gathered to hear the full story of Jefferson County Open Space, from how it was in the beginning, to the geological, climatological, and biological treasures encompassed within and outside the parks, to future directions in visitor management. Alternative methods of land conservation were introduced. Interactive discussions on diversity, equity, inclusion, and advocacy kept the participants engaged throughout the day. Read more
