attactuent z <br />Casper Creek l�NS (SBPA /92-89) <br />Paqe 2 <br />Perfortnance Criteria <br />The cntena used tor monitonng should include those basic ccmponents that compnse a <br />healthy Palustnne suub/shrub wetland ecosystem that is relatively undisturbed <br />compared to the project area. As discussed above, monitoring of a restored Palustrine <br />scrub/shrub weUand should inGude both the strudurel and fundional elements of a <br />Palustrine scrub/shrub wetland ecosystem. This includes monitoring of the vegetatio�, <br />terrestrial and aquadc invertebrates and vertebrates (i.e. inseds, birds, mammals, <br />fishes), channel benthos, birds, water and soil chemistry and processes such as food <br />c:hain support. For this restoration plan eight basic criteria have been selected. The <br />critena that the success of the restoration will be measured against are as (ollows: <br />1) VepetaHon - Overel� Objectivss. The proposed revegetatlon plan will meet all of <br />the proposed veqetaition restoration goals forth in the Casper Creek miligation <br />plan. <br />2) Vepetation • Species Mix and PerceM Cover. The restored areas (wetland and <br />buHer) shall support at least the native species set forth in the Wetland Mitigation <br />Plan for Phase I and II. The species mix should resemble that proposed in the <br />individual habitat categoncs, but sUict adherence to obtaining all of the species <br />shall not be a critena for success. By the fifth year, the percent coverage (canopy, <br />subcanopy and understory combined) of the restored areas (access roads <br />exGuded) shall be at least 80% for the wetland areas and 5096 for the upland <br />buHer areas. If an area inGudes more than 5096 exotic species (non-Palustrine <br />scrub/shrub wettand species and/or non-native species) then restoration shall not <br />be considered successiul for that area. As a flnal test af the vegetation criteria, the <br />spedes divenity, mix, and petient cover (individually and cumulative) should <br />approximate thet of similar monitored "pnsdne" areas within Silver Lake watershed <br />and other adjacent Palustnne suub/ahrub wedand ecosyatems. (See box for <br />definitian of functional Palustrine scrub/shrub wetland ecosystem.) Significant <br />degradation of existinp weUand areas, beyond that attributable to natural variation, <br />shall be considered as failure of the buffer and wetlend restoration work. <br />3) Aquadc Inwrtebrahs and Vertebntes (amphibians) - Species re-colonizing the <br />channel arsas adjacent to restored and enhanced areaa should be of a sufflcient <br />diversky and abundance to provide food chain suppoR for speciea hipher in the <br />Iood chain. Tha ranpe, distnbutlon, and densiUes ot species should be similar to <br />thoee found In functlonal wetland portiona of fhe Silver Lake Watershed and other <br />adjacent PaluaMne acrub/shrub weUand ecosyatems. <br />4) Tertestrial Ins�cts. Palustrino suuWahrub we8and inaects necessary for the <br />successful pollination of Paluatrine scrub/shrub watland plants and as food for <br />cthar spedea within the food u�ain (birda, fish) shall bs preaern. The presence of <br />the appropriate insecta shall be detertnined by monitorinp tunctlonal wetland areas <br />of tha Silver Lake wetershed and other adjacent Paluatrine sauWshrub watland <br />ecosystems with similar Paluatrine suub/shrub wetland plant species. <br />EKNIlIt .5 ._. <br />1..-i= ��� <br />
