Document Summary
Habitat model: a quantitative representation of the habitat preferences of a species. Habitat modelling a model is an approximation of reality useful for understanding the ecology of a species and/or assisting its conservation. Types of habitat models no data: habitat suitability index (hsi) variable to include? values scaled from 0 to 1 how to combine variables? presence-only data: habitat envelopes, bioclim systematic eld serve across bioclimatic range of species. 65 sites at forest streams strati ed on climate and stream size surveyed at least 4 times each habitat surveys. Conservation status: pearsoniana detected at 29 of 65 sites. Adequate e. g. includes all communities recognised by agreed national scienti c classes maintains viability and integrity of pops, spp. and communities. 90% high quality wilderness re ects the diversity of species and communities throughout their ranges. Di culties spatial separation may reduce risks from predators, disease, re. But, it also reduces chances of dispersal and recolonisation which design is better? risk spreading.
