LCityof <br />L of <br />PARKS, RECREATION & OPEN SPACE <br />Memorandum <br />To: Open Space Advisory Board <br />From: Steve Roels, Senior Natural Resource Specialist November <br />Date: 10th, 2021 <br />Re: Discussion Item 8: Plant Community Surveys Update <br />Purpose: <br />The purpose of this update is to brief OSAB on the work of staff and contractors to document plant <br />communities and vegetative characteristics of Open Space parcels. <br />Background: <br />Quantitative plant community surveys were completed by a contractor on Davidson Mesa and <br />Aquarius Open Spaces from 2018-2020. These relatively high diversity sites required an <br />experienced botanist to survey accurately and efficiently. Beginning in 2020, staff adopted the <br />same sampling technique (cover point scope transects) to begin sampling lower diversity sites <br />elsewhere in the Open Space system, where an intermediate level of expertise is sufficient. <br />Thus far, staff have sampled Coyote Run, Daughenbaugh, Hecla Lake, North, and Warembourg <br />Open Spaces. Standardized quantitative sampling facilitates comparisons within and between <br />properties, highlighting priority areas for protection and potential areas for native plant <br />restoration. Sampling transects are permanently marked, allowing for future visits to assess <br />vegetation change over time. <br />Next Steps: <br />Staff will continue surveying Open Space properties in 2022. <br />Documents Attached: Power Point Presentation <br />11 <br />
