<p>The study was conducted in two natural oak forest of Nainital (Uttarakhand) India, during 2012-2013 to determine the weight loss pattern in leaf litter of two Central Himalayan Oaks (i.e., <em>Quercus leucotrichophora</em> A. Camus. and<em> Quercus floribunda</em> Lindl.) with the help of litter bag technique. The present study concluded that weight loss proceeded throughout the study period and relatively higher within 60 days after the placement of litter bags into the soil. Among these two species, higher weight loss observed in <em>Q. floribunda</em> as compared to <em>Q. leucotrichophora</em> across both the sites. Within 365 days, average weight loss observed about 60% in <em>Q. leucotrichophora</em> and 62% in <em>Q. floribunda.</em> Decay rate coefficient rate ranged from 0.0596- 0.0014 for <em>Q. leucotrichophora </em>while it varies from 0.0558 to 0.0013 for <em>Q. floribunda</em>. The monthly relative decomposition rate (RDR) ranged between 0.0598-0.0014 g/g/day and 0.0208-0.0050 g/g/day for <em>Q. leucotrichophora </em>and <em>Q. floribunda</em>, respectively. Climatic factors (rainfall, temperature and relative humidity) also influenced the rate of decomposition.</p>
