| Summary: | Relationship between plant species response and environmental gradients is becoming a challenging question in Ecology. A study was carried out along the roadsides of Wah Cantt. Data was collected using braun-blanquet approach which identified total 36 species belonging to 18 different families. GAM was employed for plotting non-linear relationship between plant species distribution against environmental gradients while NMS application was carried to highlight the stress in plant species distribution against selected environmental gradients (Zn2+, Cu2+, Fe2+, Mn2+, O.M, EC, pH). Results obtained from GAM had shown that when predictive variable have higher values, species distribution is favorable while some species remain unaffected by higher values of environmental gradients. Similarly, results obtained from NMS confirmed that stress rate was uniform for higher values of selected environmental gradients. The study will helpful in studying plant species response against environmental gradients and in proper management of herbaceous flora growing in Wah Cantt.
