- Abstract
Paris polyphylla Smith. is a perennial herb, over exploited for its medicinal value and other anthropogenic activities like traditional method of Slash and Burn' (Jhuming) farming practice has reduced much of its habitat. As such the need to describe its potential habitats arises; this is achieved with Climate Suitability Modeling. The model was developed using 12 presence points. Temperature of coldest quarter and precipitation of warmest quarter act as an important determinant in the development of the model, these climatic variables correspond with the climatic conditions in the predicted areas which is necessary for post dehiscence maturation of seeds. Ground truthing work was being carried out to ascertain the highly predicted areas and plants were also introduced in areas predicted as suitable as well as in areas predicted as not suitable to confirm the usefulness of the model. The model also corresponds with an experiment on seed germination by temperature stratification. The study gives a different approach on validation of habitat modeling in addition with the statistical significance by observing plant response introduced in areas predicted suitable and unsuitable as well as matching plant physiology and the influences of the climatic variables on it. This work introduces a new concept modeling named 'Mosaic Model' for those species which are sensitive to different climatic conditions. In this concept model a big area can be fragmented into small areas depending on different climatic conditions. Model can be prepared for each area followed by stitching of these small models into one model (Mosaic model). This model would be able to predict the distribution of a species growing in diverse environmental condition.
