Bio Blitz in Bighill Creek, June 10, 2023 10:00-4:00

(If weather inclement, we will postpone one week to June 17th)

BCPS is interested in having a snapshot look at the range of biodiversity to be found in the lower portion of Bighill Creek. On June 10 we will host a day of data gathering from the Cochrane Ranche , up to the east end of the Bighill Creek Reserve lands (where footbridge is). We have permission for the day to roam Mt. St. Francis lands along the forested creek east of the 4th Street bridge to the end of the BCPS Reserve and up the open north slope to the top of the escarpment. Maps will be provided.

We encourage people not to pick plants or take stones/artifacts/insects/spiders with them, rather to download the iNaturalist App, store relevant information there to transfer to BCPS and take photos.



iNaturalist is easy to load onto your mobile phone. Just go to iNaturalist in your browser and follow instructions. This tool may prove useful to you for years to come.

Contact Tables:

BCPS will have tables with maps and data sheets as well as “experts” to talk to you and receive data, at two locations. One will be at the picnic area at the Cochrane Ranche near the parking lot adjacent to |1A, by the Historical Museum. Toilets are available there.

We will also have a table at the turnaround area just north of the 4th St. bridge across Bighill Creek. No toilets are available here. Water will be available at both table sites.

Maps and Data Sheets:

Available on BCPS website and facebook page after June 1.
