Staff completed the split-rail fence installation around the native interpretive gardens at Mangini Ranch Educational Preserve.

De La Salle and Campolindo High School students set up the sheet mulch and installed the vertical posts during previous Conservation Collaboration Agreement field days, and Diablo Restoration Team volunteers planted the first round of natives in the gardens.

We encourage you to make a reservation at the Mangini Preserve to see the flourishing natives and explore the flora around the rest of the preserve.

Many volunteers joined us at the Curry Canyon Ranch for some spring cleaning around the field station. Together they removed all the tiny pesky weeds from the gravel and pavers surrounding the property.

Volunteers were rewarded with a beautiful day with excellent views of the Mount Diablo summit.

Stewards in the Field

Trail Dogs refurbished the Coralwood Trail at Mangini Ranch Educational Preserve, Twin Ponds Loop Trail in Shell Ridge Open Space, and Coyote Trail at Morgan Territory Regional Preserve. They also removed fencing at Black Diamond Mines Regional Preserve.

Stewards protected additional oak seedlings at Oak Hill Lane, and continued to observe copious wildflowers and flowing creeks across all Save Mount Diablo properties.

Save Mount Diablo’s two-week BioBlitz (April 15th–April 30th) focusing on the SCU Lightning Complex fire footprint has ended.

This year was the third and final focusing on the SCU Lightning Complex fire footprint in partnership with California Native Plant Society and their Fire Followers iNaturalist campaign.

We had 1,014 observations uploaded onto iNaturalist during the two-week period from 54 observers.

There were thousands of fire followers across the fire footprint, including fire poppies, golden eardrops, and whispering bells. Participants saw chaparral plants growing even more after last year’s growth.

This is our third and final year focusing on this fire footprint, and the vegetation is much denser than it was in 2021 and 2022. Thank you to everyone who participated in Save Mount Diablo’s 2022 BioBlitz!

Please sign up for our recap events on May 17th from 4 to 6 PM.
