I am interested in using Conset for an area prioritization study for
Moroccan Herpetofauna. Is it possible to initialize Conset from a user-
defined set of areas (a current protected area system in this case),
like in resnet (e.g pawar et al. 2007. Biol. Cons. 136).
I use a richness map made by Maxent (113 species) and want to analyse
the existing protected areas (do you have a recommendation on
available heuristics?) as well as new area prioritization (initialized
on the existing protected areas).
Do you recommend using Consnet or is it better to use Resnet since our
goals are quite simple, lacking Multiple criteria etc.?
Looking forward to hear from you.

kind regards,

Hi Philip,

To answer your first questions, It is possible to initialize ConsNet
from a user defined set of areas. This feature is called "permanently
included cells". These cells will be included in every solution, and
can be used to represent current protected areas.

ConsNet can calculate the representation for each species in your
current protected areas, and for the whole region. This will help you
define appropriate representation targets.

Once your representation targets have been defined, you will use both
heuristic methods and the more powerful search engine to identify
priority areas. All of the heuristics in ConsNet are fast, so I
recommend trying them all to see what happens. Once you have a
heuristic solution built, I recommend using the ITS objective
(intransitive shape) to search for an improved solution that is
spatially compact and has a minimal cardinality.

Dear michael,
 
Thank you for your fast response to my questions. I have chosen to use ConsNet after I read your mail. I will use ConsNet using all available heuristics and as you say, just see what happens. I have another question concerning the permanently included cells feature. Is the sentence below correct. This method was used by Pawar et al. 2007 (ResNet) but is it the same for ConsNet?
 
"for area prioritization the  ConsNet feature "permanently included cells" was used with the existing protected area included in every solution. This procedure was used because this procedure identifies areas by which existing protected area network can be augmented, rather than proposing a new conservation area network that reconfigures the existing one."
 
 
Many thanks in advance!
 
Philip

Yes, this method is the same in ConsNet as it was in ResNet. -Sahotra
