<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration xiv <br />iii. If a natal or pupping den is found within the Impact Area or within 200-feet of the <br />Impact Area boundary, USFWS and CDFW will be notified immediately. The <br />den will not be disturbed or destroyed, depending on the applicable site <br />conditions and characteristics of the den, the soil investigation site may be <br />moved. <br /> <br />MM BIO-18: Botanical Resources <br />a. All botanical evaluations will be conducted by a qualified botanist, who at a minimum <br />shall have experience conducting floristic field surveys; knowledge of plant <br />taxonomy and plant community ecology and classification; familiarity with the plants <br />of the area, including special-status and locally significant plants; familiarity with the <br />appropriate state and federal statutes related to plants and plant collecting; and <br />experience with analyzing impacts of a project on native plants and communities. <br /> <br />b. A qualified botanist will conduct a habitat assessment to determine whether the <br />habitat is appropriate for special-status plants. If suitable habitat is present, the <br />qualified botanist will conduct a habitat quality assessment to determine the potential <br />for presence of sensitive plant species. The habitat quality assessment will consider <br />factors such as soil type, degree and frequency of previous soil disturbance, <br />abundance of invasive species, and distance from known sensitive plant <br />occurrences. If a qualified botanist determines that special-status plants are likely to <br />occur at a proposed Impact Area, a botanical survey will be conducted within the <br />Impact Area at each soil investigation site. When feasible based on scheduling and <br />property access, the surveys will be conducted at proper times of year when special- <br />status and locally significant plants are both evident and identifiable; will be floristic <br />in nature, ensuring that all plants observed are identified to a level sufficient for <br />determining rarity, and will be conducted using systematic field techniques in all <br />habitats of the site to ensure thorough coverage of potential Impact Areas. <br /> <br />c. Any special-status plant species present within 10 meters of an Impact Area will be <br />flagged, or mapped using a GPS, for avoidance. A qualified botanist will establish an <br />appropriate buffer. During field activities avoidance of the buffered area will be <br />enforced by an environmental monitor to ensure that special-status plants are <br />avoided to the maximum extent practicable. <br /> <br />d. If special-status plant species (excluding listed species) are present within the <br />Impact Area and impacts cannot practicably be avoided, a qualified botanist will <br />evaluate the following criteria to ensure these impacts are less than significant: <br /> <br />i. the total range and distribution of the species, <br />ii. local population abundance, <br />iii. approximate number of individuals potentially impacted, <br />iv. area of habitat potentially impacted, <br />v. life history of the species (annual versus perennial and seedbank dynamics),
