A Preliminary Exploration of Mammal Diversity Differences among Three Different Forest Origin Types on the Southern Slope of the Qinling Mountains
From 2022 to 2023,a survey was conducted using infrared-triggered cameras to investigate the differences in mammal diversity among primary forests,secondary forests,and planted forests at an altitude of around 2 600 m on the southern slope of the Qinling Mountains.The survey found that the total effective working days of the infrared cameras amounted to 2,149 days,with a total of 5 351 image materials collected and 597 independent and valid photographs.A total of 17 species of mam-mals were recorded,with takin(goral)and forest musk deer having the highest capture rates in all re-gions.Additionally,leopard cats,masked palm civets,yellow-throated martens,Asian small-clawed otters,and hog badgers were only captured in secondary forests.The secondary forest exhibi-ted the highest richness,diversity index,and evenness index,while its dominance index was the low-est.The indices for primary and planted forests showed little difference.The similarity between pri-mary and planted forests was the greatest,followed by the similarity between primary and secondary forests,and the similarity between secondary and planted forests was the least.This study indicates that the mammal diversity in secondary forests,where the herbaceous layer and shrubbery are denser and where there is no human disturbance,is higher than that in primary and planted forests with spar-ser herbaceous layers and shrubbery.This indicates that during the establishment and conservation of planted forests,emphasis should be placed on increasing the vegetation diversity under the canopy and further reducing human disturbance to provide abundant food resources and diverse habitats for animal communities,thereby promoting the healthy development of forest ecosystems.
