Soil invertebrates play a crucial role in breakdown of organic material and soil nutrient cycling processes. Most studies on soil invertebrate have focused on their response to deer exclusion and canopy gap creation treatment individually but not many studies have looked at the response to a combination of both treatments. Our study takes place in evergreen broad-leaved forests, where deer density occurs between 10 - 13.5 deer km-2 and incorporates a combination of canopy gap and deer exclosure treatments. We investigated the soil chemical property, litter dry mass and compared the temporal effects of treatments to invertebrate abundance. We sorted and identified invertebrates according to taxonomic order. Principal response curve (PRC) suggest that Blattodea increased while Araneae, Isopoda and Collembola decreased following disturbance. Our results show a significant increase in Isopoda, Araneae and Collembola in deer exclusion treatments and Chilopoda in combined gap and deer exclusion treatment, after 14 years, compared to the control. However, recovery in the gap treatments were limited even after 14 years in the case of Talitridae (Amphipoda) and Araneae. We conclude that gap treatments in the presence of deer have a long-term negative effect on soil invertebrate groups which persists even after 14 years.
