The concept of functional diversity is critical in the field of forest ecology as it helps determine trends in community structure and worldwide change by examining variations in functional traits among plants. Functional traits like leaf traits, stem traits, root traits etc., are characteristics of a species that incorporate its ecological and evolutionary history and can be used to predict both its response and impact on ecosystem function. During the present study, six functional leaf traits viz., leaf size (LS), specific leaf area (SLA), leaf dry matter content (LDMC), leaf nitrogen content (LNC), leaf phosphorus content (LPC), and leaf nitrogen to phosphorus ratio (N:P) were evaluated for a variety of trees and shrubs in the forests of semi-arid regions of Haryana, India i.e., Site I-Dulana (Mahendergarh), Site II-Kheri Batter (Charkhi Dadri) and Site III-Asalwas Dubia (Bhiwani). Functional leaf trait values showed a significant variation.  LS was reported to be positively correlated with SLA(0.39) and N:P(0.11) while negatively correlated with LDMC(-0.26) LNC(-0.29) and LPC(-0.16). The selected plant species displayed a negative but weak correlation between SLA and LNC(-0.05) whilst a strong positive correlation between Nitrogen (N) and Phosphorus (P)(0.36). All three Sites had the value of N:P ranging from 12.58 to 65.69, thus exhibiting P limitation.  The present study advances the field of functional ecology in Haryana's tropical dry forests significantly.  This is also crucial to forecast community formation trends and characterize the contributions of different species to ecological processes.
