Maxent modelling for endangered species

[Brett Wilson]

Hi,

I am currently using Maxent to model the potential distribution of a rare apple species (Malus niedzwetzkyana). Currently I have only 28 location points for this species which I know limits the quality of my model. I am wondering if there is a way to produce a high quality model from this limited data?

Thanks in advance,

Brett Wilson

Dear Brett

If these 28 locations have a good spatial coverage (e.c. are not in a  radius of 100m each other), then are a good starting point.]

Also, important is the selection of the enviro data and its spatial dimension (pixel size).

Hi Brett,

You might want to take a look at this paper: 

https://www.researchgate.net/publication/281399394_Declining_relict_plants_climate_effect_or_seed_dispersal_disruption_A_landscape-scale_approach_Supplementary_Material

In that work, we dealt with low number of presences and took into account different aspects, as for instance spatial autocorrelation of those presences (as Dimitris pointed out). 

Good luck!

Thanks everybody for your help! Think my model looks fairly reliable now.
