' October is often considered growth relevant in this area (spring and summer) and autumn is often split between summer and winter with winter starting in November and ending' in March. Thus, ecologically it is a three season division - spring, summer and winter. In the midwest a four-season ' division is more applicable than in the high plains were there is biologically only three seasons. In the alpine tundra and high mountain forests there are actually only two seasons;- summer and winter. ' 2. Topsoiling - A great deal of topsoiling was done in the last year. A. Locations of topsoiling - All the topsoiling done in the last year was on the pit west ' of the main road. Approximately 58.82 acres of land was topsoiled in the last year. I B. Depth of topsoiling - Topsoil depth far exceeded the minimums required by the ' plan and if subsoil is included with topsoil, depths in some locations exceeded six feet and in some locations combined overburden (subsoil) and topsoil depths were 10 to ' 20 feet. C. Final grading of topsoiled lands - All lands that were topsoiled were final graded. ' No slopes exceed 5:1. In fact, as discussed elsewhere, the final grading closely matches the original slope gradients and general topographic configuration. ' 3. Accommodation for drainage - Drainage in recently completed portions has been fully connected and closely follow original patterns and courses providing reconnection with adjacent drainageways. Elsewhere, drainage is still being contained with;pit areas, but as ' those are completed, the drainage will be opened and reconnected. 4. Revegetation - A total of 58.82 acres was seeded in the last year. This is the same acreage ' that was topsoiled and final graded. A. Acres seeded - 58.82 ' B. Seeding provided - Utilized upland mix from Reclamation Permit. ' C. Special treatments - Cracked corn had to be included in the seeding to increase seed flow through the drill gates. Any corn plants that appear will be removed (or ' harvested and turned into ethanol or barbecued and eaten). However, it is unlikely any plants that develop will survive for long given the dry habitat. I ' D. Status of new seedings as of report date - The seeding is still fai too young to make an assessment. Due to a lack of moisture little or no germination las occurred. ' E. Status of older revegetation as of report date (describe growth rates, cover, invasive species, native invasion, and difficulties) - All the older revegetation areas exhibit poor growth this year due to lack of moisture. Species frequency distributions ' continue to shift toward native dominance with remaining introduced species declining further. Little noxious weed invasion has occurred and even non-noxious annual weeds are much reduced. Status report for 2007 (July 15, 2007) Page 8 of 10
