APPENDIX GWETLAND MITIGATION BANKING: SUMMARY CHART (continued)Study Location Description Results: Permit Success Results: Ecological Success Notes: WildlifeDeWeeseand Gould(1994) -- FromAmbrose(2000)Fennessy et al.(2004)Gallihugh andRogner (1998)– From NRC(2001)Johnson et al.(2000)San FranciscoBay RegionOhioChicago,IllinoisWashingtonA qualitative review of permit complianceand ecological success on a permit compliancescale of 0-10 (10 indicating fullcompliance) and a ecological value ratingof 0 -10 (10 indicating among the bestexamples of habitat type in the area) of30 projects in San Francisco Bay Region.Study of structure and function of 9 naturaland 10 mitigation sites in Ohio.Only 3 projects reviewed were 100percent compliant, 6 were 85-99 percentcompliant, 6 were 75-84 percent compliant,12 were 45-74 percent compliant,1 was 1-14 percent compliant, 2 were0 percent compliant. Also, 599 acres ofmitigation were required for 415 acres ofimpacts, but only 537.2 acres were actuallycreated. Some of the projects mayhave been compliant, but there were stillquestions about the long-term sustainabilityof the site.Of the 29 sites evaluated only 1 (3 percent)was rated to have very high value,13 judged average or slightly above orbelow average, 6 well below average,2 judged to have no value. Ecologicalsuccess was correlated with permit compliance(so sites with higher ecologicalsuccess had higher permit compliance).The mitigation was not replacing in kindhabitat values.Mitigation wetlands were generallydryer. Natural wetlands had faster ratesof decomposition, higher IBI scores (vegetationcommunity composition and speciesrichness), biomass production, soilnutrient concentrations, and plant litterconcentrations, and different hydrologicalpatterns than mitigation wetlands. Therewere major differences in invertebratenumbers of taxa, abundance of tolerantand specialist species, and communitymetrics. Amphibian communities alsodiffered. The conclusion is that mitigationis creating a new subclass of wetlands onthe landscapeEvaluate 61 permits for 128 projects. 17 percent of proposed wetland vegetationhad been established, 22 percenthad established vegetation other thanthat had been proposed. 52 percent ofwetlands had excessive or unplannedopen water, 9 percent had insufficienthydrology. The wetland area lost was 117hectares, and 144 hectares was mitigated(but 29 hectares were not established,and 99 hectares had insufficient hydrology).Evaluated 45 projects for permit compliance.Overall, 13 projects (29 percent) werein full compliance. Forty-two projects(93 percent) were implemented, andof those, 23 projects (55 percent) wereimplemented to plan. Thirty-four projectshad performance standards that could beevaluated, and of those, 12 projects (35percent) were meeting all performancestandards assessable by this study.Wildlife data were collected foreach site, and wildlife habitat andusage performance standardswere encountered in permit files(these were generally vague anddifficult to assess). The studyincludes a list of all the performancestandards encountered.106 Environmental Law Institute
APPENDIX GWETLAND MITIGATION BANKING: SUMMARY CHART (continued)Study Location Description Results: Permit Success Results: Ecological Success Notes: WildlifeJohnson et al.(2002)Josselyn et al.(1993) – FromAmbrose(2000)Mack andMicacchion(2006)McEnespy andHymanson(1997) -- FromAmbrose(2000)WashingtonCaliforniaOhioCaliforniaEvaluated 24 mitigation projects todetermine the success of the projectsfrom an ecological perspective. Criteriaincluded established required acreage,attained performance standards, fulfilledgoals, contribution of mitigation toperformance of functions, comparisonof type and scale of functions betweenmitigation and natural sites.Evaluated restoration projects underCalifornia State Coastal Conservancy’sProgram.Evaluation of 12 Ohio wetlands mitigationbanks based on biological, biogeochemical,and hydrological monitoringtechniques. Assessed nearly 400 hectares.Criteria for success = maximizing areasdefined as “wetland”, minimizing areas ofopen water, having hydroperiods whichmimic hydroperiods of natural wetlands,maximizing cover of perennial nativehydrophytes, minimizing cover of invasiveplant species, VIBI scores of 40 - 60.Reviewed compliance with CaliforniaCoastal Commission Permits.50 percent met 90-100 percent of thepermit conditions, 4 met fewer than 32percent of permit conditions.Phase II found that of 24 mitigationprojects studied 13 percent were fullysuccessful, 33 percent were moderatelysuccessful, 33 percent were minimallysuccessful, 21 percent were not successful.65 percent of total acreage lostwas replaced by creating or restoringwetlands resulting in a net loss of 24.18acres, but 2/3 of total acreage of mitigationthat was established was enhancement.71 percent of private mitigationprojects were successful, while 35 percentof public mitigation projects were judgedsuccessful. In total, 79 percent of mitigationwere at least somewhat successful,63 percent at least partially compensatedfor permitted wetland losses. 21 percentmet performance standards.All evaluated functions were improvedat 36 percent of sites, 48 percent of sitesat least one function was not approved,1 site failed in all functions evaluated.59 percent effective at achieving goals,45 percent effective at producing habitatbenefits, 5 percent ineffective. The majorityof sites did not produce a self-sustainingecosystem.Of bank area assessed, about 25 percentwas not wetland. Of the wetland acreage25 percent was poor, 58 percent was fair,18 percent was good quality using vegetationdata compared to ecoregionallycalibrated scores from natural referencewetlands. For amphibian communities,amphibian community composition andquality was significantly lower at banksthan natural forest, shrub, or emergentwetlands. Pond-breed salamanders andforest dependent frog species were nearlyabsent from banks. Of banks surveyed 3were mostly successful, 5 were successfulin some areas but failed others, 4 mostlyfailed.6 of the 23 projects reviewed were givenAs (the highest grade), 6 were givenBs, 6 were given Cs, 4 Ds, and one siteearned an F.55 percent of sites had a moderatecontribution to wildlife functions.Enhancement sites had minimalcontribution to wildlife function.The study concludes that mitigationsites did not do a great job atcontributing to wildlife functions.Design of U.S. Habitat Banking Systems to Support the Conservation of Wildlife Habitat and At-Risk Species 107
