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.

 

1.    What type of land holding do you or others in your organization manage? (Click all that apply)

privately-owned open space

public-owned open space

general land trust

restoration site

habitat reserve or ecological refuge

park or recreational area

multiple use (e.g., habitat reserve and recreational area)

2.    Approximately, how large of an area is this holding? (If multiple holdings then, how large on average?)

< 10 acres (4 hectares)

10 100 acres (40 hectares)

100 640 acres

1 10 square miles (2. 6 26 square kilometers)

10 50 square miles

50 100 square miles

> 100 square miles

 

 

3.    Click on those types of land surface features that are of interest. For these features, click on the size of the smallest feature or characteristic length associated each feature (in meters)?       

  <0.5 0.5 1 1 5 6 10 11 20 20 50 > 50
invasive plants 
removal of vegetation 
reduction of leaf cover or vigor
vegetation dieback
increasing bare soil exposure   
soil erosion
fire scars
gullying  
soil deposition
trampling of vegetation 
trail formation
trail widening and coalescing
   
 

4.    Given the ephemeral nature of shrubland and grassland vegetation in southern California, their response on multi-year imagery can vary, even when images are captured on or near anniversary dates.  To what degree might you be interested in year-to-year differences or changes in the following variables?

  very interested 

mildly
     interested    

no
     interest    

proportion of green herb cover             
presence/absence of annuals          
shrub or tree leaf area index          
 

 

5.    Do you or someone in your organization conduct any type of comprehensive monitoring of the land holding that you manage? 

              

Yes

No     Not pertinent          

             

 

   

6.    If you answered yes to the previous question, by what means (click on any that are pertinent)?

    Ground reconnaissance

    Aircraft reconnaissance (Visual inspection and/or hand sketching on maps)

    Field sampling (e.g., plots and/or transects)

    Remotely sensed imagery (including aerial photography)

    Combination of ground and remote sensing approaches

     

  

7.    Is it important to monitor your entire land holding in a comprehensive (i.e., spatially complete) manner?

      

Yes No     Not pertinent          

      

 
 

 

8.    Is it feasible to monitor your entire land holding in a comprehensive manner with ground-based procedures?

      

Yes No     Not pertinent          

      

 
 

 

9.    Do you currently use any type of remotely sensed images (including aerial photographs), or maps or tabular data derived from such imagery for purposes of monitoring land cover changes?

      

Yes No     Not pertinent          

      

 

 

10.    If you answered yes to the previous question, then what type of imagery (click on any that are pertinent)?

    B & W aerial photographs

    color aerial photographs

    color infrared aerial photographs

    digital orthophotographs

    other digital airborne imagery

    digital satellite imagery

 

 

11.    Balancing (1) the desire for monitoring information,  (2) the rate at which disturbance related effects are likely to occur, and (3) the realities of funding, for what time interval should maps of land cover changes for your landholdings be produced?

    Annually

    Every two years

    Every three years

    Every four years

    Every five years

    Every five to seven years

    Every eight to ten years

 

12.    Is it important and/or would it be useful to have information on land use and land cover changes that occur on the periphery of your land holdings?

Yes No

    Not pertinent        

 

 
 

 

13.    If you answered yes to the previous question, for how wide of strip or buffer surrounding your land holding (in meters)?

          100 m
          200 m
          500 m
          1000 m
          2000 m
          5000 m
          >5000 m

 

 

               

14.    Balancing (1) the desire for monitoring information, (2) the rate at which surrounding changes in land use and land cover are likely to occur, and (3) the realities of funding, between what time interval should maps of land use and land cover changes for lands adjacent to your land holdings be produced?

    Annually

    Every two years

    Every three years

    Every four years

    Every five years

    Every five to seven years

    Every eight to ten years
