Appendix D: Run instructions for ECOSEARCH
Installation:
Down-load a copy of ECOSEARCH from:
http://www.mbr-pwrc.usgs.gov/software .
If you have any problems down-loading or running ECOSEARCH, please contact:

Data Preparation:
Prepare the landscape data as separate grids in ArcInfo/GRID. Then aggregate
the data into a single ASCII file using the GRID command:
OutFile.dat = SAMPLE (mask grid, vegetative structure grid, wetland status
grid, soil type grid, topography grid)
Mask grid determines which cells are to be sampled. Data for vegetative
structure, wetland status, soil type, and topography are all described in
Chapter 2. This creates a single ASCII file containing the cell values of all
the input grids. Exported data will be in ASCII and will include the mask
value, x-coordinate, y-coordinate, vegetation code, wetland code, soil code,
and topography code, all separated with commas. The x and y coordinates will
be in the units of the input grids.
Running ECOSEARCH:
- Click-on the START button, select PROGRAMS, then select the ECOSRCH icon.
An ECOSEARCH window will appear welcoming the user to Version 1.0.
- Select the desired species by clicking-on the species name. Make sure that
only the boxes that you desire have a check in it. The SORT button sorts the
species list in alphabetical order on the four-letter species code. Appendix A
contains the common name, scientific name, four-letter code and approximate
distribution for > 300 species of inland, terrestrial wildlife.
- Select a data file. The SA.All data file (South Amherst, Massachusetts
[used in Chapter 3]) is included as an example. Use the BROWSE button to view
multiple landscape grids and explicitly set the input data file by clicking on
it.
- Set the output dimensions. The maximum area for an analysis is 500 by 500
cells (50m cells would represent 72,500 hectares. The maximum size of the
SA.ALL file is 120 x 120.
- Select output options. Choices are:
- .DAT gives the species occurrence
map that can be printed with a line printer;
- .EDG provides a map of all
defined edge habitats;
- .HAB represents the species breeding habitat
(labeled 1), feeding habitat (2), or both breeding and feeding habitat (3);
-
.MAP gives the species-occurrence map that can be imported into Arc/Info; and
- .BDM is a cumulative species-occurrence or species-richness map.
Use the
BROWSE button to locate your desired output directory, explicitly set the
output file by typing in a name that includes the 4-letter species code with
the proper extension. If you make multiple runs for the same species, the
program may stop or over-write the earlier file. Take the time to rename files
and delete old files.
- Provide a label for the output (20 character maximum). This is optional
because the label can be added later in ArcView. The printed label contains
the 4-letter species code, species common name, selected label, date, and
time. The date and time helps keep track of multiple analyses.
- Select PLOT or QUIT. All subprograms are written in FORTRAN. Various
run-time messages are printed from DOS to inform the user of the progress of
the analysis. With faster machines, these messages appear as a blur. The
program was initially designed to run on a 486 Personal Computer (25 mHz).
- Once the analysis is completed, the user has two choices:
- select the
FILE menu and choose PRINT, CLOSE, or QUIT for each species map; or
- bring
the map into Grid or ArcView for further analysis or printing. This is done by
minimizing ECOSRCH, starting ArcInfo, and using the Arc command: asciigrid
The output.Map file was generated by ECOSEARCH while
outgrid is that same file in GRID format. Now minimize ArcInfo. Start ArcView.
Please note ArcView must have the ‘Spatial Analyst' extension installed and
turned on. Add outgrid as a grid theme where 0 = absence, 1 = presence, and no
data is black for single species maps and 0 = no species, 1 to x = number of
species out of the x species checked for a biodiversity map, and no data being
black for these biodiversity maps.
- Users restart ECOSEARCH for a new analysis by clicking the old species off,
clicking a new one on, and running it again.
- If the program crashes, click-on the START button, select Shut-down,
select End Task, and Reboot.
