| Revegetation Plan continued: |
| Implementation Schedule The revegetation site plans include an implementation schedule. It is LADWP’s intent to commence the projects as stated in the schedule. In the event of unforeseen circumstances, the schedule may be subject to delay. This situation will not change LADWP’s obligation to mitigate the impacts described in the EIR. Schedule changes will be addressed in the annual report. Species Lists Lists of species that will be considered for seed mixes or grown for transplanting are included with each site. As many species as possible from the lists will be tested for survival at a site before any large scale planting or seeding occurs. Each species has a superscript number to reference its source for inclusion. These sources are as follows: 1a) 1984-87 LADWP on-site vegetation parcel inventory, 1b) 1984-87 LADWP vegetation parcel inventory from parcels within 5 mi. of the site, 2) NRCS soil description/plant associations, and 3) personal observations. Species lists and goals were derived either by using vegetation cover and composition data from the site if it was mapped prior to impact or from plant communities within a five mile radius of the site. For sites mapped prior to impact, site goals and mapped species, cover, and composition are the same. When communities within a 5 mile radius were used, they were narrowed down to those that were similar in elevation and habitat (i.e. soil type and depth to water) and averaged for live cover. Composition goals were determined to be half of the combined number of perennial species from the selected communities. Plant communities that had high occurrences of weedy native or non-native species were used for species lists but not live cover or composition goals. Native perennial species that are opportunistic were not included in any species list because it is assumed they will occur without assistance. Examples of these species include: Nevada saltbush, rubber rabbitbrush, and big sagebrush. Trace species that were not included in the 1984-87 vegetation map summary database will be added to species lists prior to beginning the revegetation work. This research may increase composition numbers and species added to mixes or grown for transplanting. |
