How many species are the minimun to obtain a good result?

[Maria M]

Hello

I have two doubts, I hope someone can help me:

1. Do you know how many species are the minimun to obtain a good result?, I have only six bird species, all of the same family.

2. ConsNet send this error: Indexing cells adjusting

GRID: adjacency data

ERR: Null

 If someone could resolve my doubts, I would be very gratefull.

Hi Maria,

I apologize that ConsNet doesn't print out better information when it fails.  I believe the error you described happens when ConsNet is using cells with an arbitrary shape.  Is this correct?

My first guess is that there is an error in the adjacency file that defines the spatial relationships between cells.  I could not reproduce the issue with our test files.  If I had more information, I might be able to pinpoint the exact cause.  Try some of the steps below, and feel free to email me at michael.c...@gmail.com

1)  When an error occurs, the black console behind ConsNet prints 

out the location of the error.  If you can copy and print this 
information, that would be helpful.  Copying this information is a 
little tricky.  From the main menu for the command window, you have to 
select "edit -> select all" followed by "edit -> copy". 

2)  If you files are small, zip them up and send them to me.  I will try 

to reproduce the issue here.

For your second question:  Is six species enough?

Running an analysis with six species can generate useful insights about the land that might be most important for the conservation of those species.  When combined with other data, you can probably use this to suggest areas to place under conservation.  

However, if your goal is to design a complete conservation area network, I would recommend expanding your analysis to a broader range of species and other biodiversity surrogates.
