P I Performance Standards A minimum of 2.97 acres of jurisdictional waters, including 0.88 acre of wetland, will be present in the stream channel at the end of 5 years. The target percent cover or survival rates by plant species and ecological planting zones are r outlined in Table 3-3. Monitoring will cease after 5 years if these targets have been met. If any of the targets are not met, monitoring will continue until reasonable progress toward the final success criteria is shown. i t I Creekside Zone. The creekside ecological zone must have an overall canopy cover of 10% by the end of the third growing season and 26% by the end of the fifth growing season. These performance standards were derived from the regional growth rate of 2 feet per year in canopy diameter for willows and cottonwoods. This growth-rate estimate was combined with the specified planting density of 15 feet on center(225 per acre) to create a model of percent cover for years 3-and 5 (Figure 3-5). The canopy is expected to close by year 10, assuming 80% survival over the first 2 years, 75% through the first 5 years, and no further mortality after year 5. This estimate assumes an increase in canopy cover at a rate of 2 feet per year until the canopy reaches 20 feet in diameter. This closure estimate is conservative. Closure, defined as 90% cover, is expected to be achieved sooner because of natural establishment of riparian species. Cottonwood-Willow Zone. Performance standards for the cottonwood-willow zone are the same as those for the creekside zone. `k Oak-Woodland Zone. Survivorship of plantings in the oak-woodland zone must be at least 80% at the end of the second growing season and at least 75% by the end of the fifth growing season.
