We are seeking input from professionals such as yourself, to help us determine
the direction of future research. Your insights and opinions are important and
valued. Your selection is based upon your knowledge and experience with key
land use and habitat management issues. Thank you for participating.

4. Given the ephemeral nature of shrubland and
grassland vegetation in southern California, their response on multi-year imagery can vary,

| |
very interested
|
mildly
interested
|
no
interest
|
| proportion of green herb cover |
