  9. 9. 11/11/09
  10. 10. Riparian Solutions 11/11/09 <ul><li>Arundo priority will be on the creek sides </li></ul><ul><li>Chemical and cuttings will be needed for the areas on the creek.  Followed by revegetation. </li></ul><ul><li>Plant larger canopy with more mature natives to help understory thrive </li></ul><ul><li>Plant understory natives in mosaic pattern in fall for full rain fall. </li></ul>
  11. 11. Riparian Processes 11/11/09 <ul><li>Aliso Creek is a type B stream.

  16. 16. Riparian– Target Species 11/11/09 Bell’s Vireo MONITORING NEEDS 1. Conduct regular monitoring of vireo populations. 2. Conduct thorough range wide surveys. 3. Conduct a statewide inventory of riparian habitat. 4. Color banding to collect data for demographic and dispersal analysis. RESEARCH NEEDS 1. Determine whether any reproductive parameters are density-dependent. 2. Determine whether dispersal is density-dependent. 3. Examine the effect of different cowbird control regimes on vireo parasitism rates and reproductive success. 4. Evaluate the use of restored habitat by vireos. 5. Investigate the status of wintering habitat and identify current or potential threats. 6. Identify predators and establish means of control. 7. Identify additional and potential Least Bell's Vireo breeding habitat within its historical range. California Partners in Flight Riparian Bird Conservation Plan

  18. 18. Sage Scrub – Target Species 11/11/09 Gnatcatcher <ul><li>“ California Gnatcatcher's preferred habitat type coinciding with the description for high real estate value (coastal, low-elevation, shallowly sloped or level lands)” </li></ul><ul><li>It usually takes 4 years for California Gnatcatchers to return and begin nesting at a restored site. </li></ul><ul><li>Also susceptible to Cowbird brood parasitism. </li></ul><ul><li>Rodents, snakes, scrub-jays, road runners, feral or domestic cats are other predators </li></ul><ul><li>Limited and specific habitat requirements make this a fragile species. </li></ul><ul><li>Typical nesting plants </li></ul><ul><ul><li>California sagebrush, </li></ul></ul><ul><ul><li>California buckwheat </li></ul></ul><ul><ul><li>California sunflower </li></ul></ul><ul><ul><li>Laurel Sumac </li></ul></ul>
  19. 19. Sage Scrub – Target Species 11/11/09 Gnatcatcher <ul><li>MANAGEMENT ISSUES: </li></ul><ul><li>FIRE AND EXOTIC VEGETATION (Which can hinder their ability to take hold in an area). </li></ul><ul><li>HABITAT FRAGMENTATION (They need at least 1hec to 9hec) </li></ul><ul><li>PREDATION: </li></ul><ul><ul><li>Predation is the most common cause of gnatcatcher nest failure. Information is lacking as to whether this predation rate is influenced by anthropogenic factors, although typical edge effects on gnatcatcher breeding is not evident (Atwood 1998). </li></ul></ul><ul><li> California Partners in Flight Coastal Scrub and Chaparral Bird Conservation Plan </li></ul>
  20. 20. Grasslands 11/11/09 <ul><li>Grasslands would be used to replace greenbelts around housing as a means to mitigate run off. </li></ul><ul><li>Less expensive to maintain than turf and won’t need fertilizers or others chemical means to keep aesthetically pleasing. </li></ul><ul><li>Target Species – Monarch Butterfly </li></ul><ul><li>“ A certified station must include at least two kinds of milkweed and four other nectar plants that bloom at different times.” Monarch Watch </li></ul>
  21. 21. Conclusion 11/11/09 By using a variety of habitats our hopes are to bring biological diversity to a unique area nestled in a very urban part of Aliso Vijeo. The main goal of mitigating run off and erosion can lead to many outcomes. The inclusion of local education can help lower costs of monitoring the restoration. And by adding education about urban run off, natives and water quality it can reduce water quality issues coming from the housing developments feeding into the watershed. Consensus is also a huge part of the restoration process and would be included in this undertaking.
  22. 22. Conclusion 11/11/09 <ul><li>Water quality to aquifers and beaches </li></ul><ul><li>Biodiversity at site and further down the watershed </li></ul><ul><li>Education brings in interest and community particpation </li></ul><ul><li>Include monitoring in the education plan to help maintain quality habitats </li></ul><ul><li>Cost savings with grasslands for turf and higher quality water </li></ul><ul><li>Recreation for hikers and birdwatchers by bringing endagered species to Aliso Park </li></ul>
