英文摘要 | Ungulates in temperate regions are increasing in range and abundance, leading to concerns that browsing and trampling reach levels that hamper tree recruitment and forest regeneration. However, studies that actually quantify the long-term effects of ungulates on forest succession are scarce. Here, we use a chronosequence of ungulate exclosures (fenced) and control (unfenced) plots to assess the long-term effects of ungulates on forest structure, diversity and litter depth in forests on poor sandy soils at the Veluwe, the Netherlands, which have moderate ungulate densities ((x) over bar = 13.6 ungulates km(-2)). We surveyed the vegetation in 27 paired fenced and unfenced plots that ranged from 1 to 33 years old, and measured seven variables to characterize forest structure (stem density, canopy cover and understory vegetation cover), composition (Shannon diversity, species richness and conifer proportion) and leaf litter depth. We found on average that fencing compared to unfencing reduced understory vegetation cover (fenced = 64.3 +/- 20.2%, unfenced = 80.3 +/- 19.4%), increased canopy cover (fenced = 47.4 +/- 30.1%, unfenced = 29.3 +/- 21.1%), tree species richness (fenced = 4.5 +/- 1.3 spp., unfenced = 2.7 +/- 1.2 spp.), tree Shannon diversity (fenced = 1.1 +/- 0.3 index, unfenced = 0.7 +/- 0.3 index) and litter layer depth (fenced = 4.4 +/- 1.4 cm, unfenced = 2.4 +/- 1.1 cm). While fenced plots developed woody vegetation with palatable broadleaved species such as Betula pendula, Betula pubescens, Prunus serotina, and Quercus robur, unfenced plots were not associated with any particular tree species. Our results show that current ungulate densities in this system have pronounced long-term effects on forest structure, composition and litter depth, implying that ungulates can slow down natural succession of temperate forest, from light demanding to shade tolerant species, by keeping the system in an arrested state consisting of light demanding species. |
