“…Trampling effects of the visitors on the soil and vegetation have been reported by many authors (Jim 1987;Sarah and Zhevelev 2007) and these effects are long term in some cases (Kissling et al 2009). Increasing visitors' pressure results in the soil compaction, increased bulk densities, decreased soil porosity and decreased organic matter contents (Marion and Cole 1996;Sarah and Zhevelev 2007).…”

“…Many studies have been undertaken to increase our understanding of factors that facilitate a high diversity of native species in urban parks (Hermy and Cornelis 2000; Nakamura et al 2005; Weifeng et al 2006; LaPaixa and Freedman 2010). Trampling (Jim 1998) and other factors associated with the presence of users, referred to as “visitor pressure” (Sarah and Zhevelev 2007; Zhevelev and Sarah 2008), are assumed to be the most important reasons for the decline in species diversity of understory vegetation in parks. Negative effects of trampling on the species diversity of understory plants have been reported for urban habitats (Bhuju and Ohsawa 1998; Sarah and Zhevelev 2007; Zhevelev and Sarah 2008).…”

Urban forest stands are usually spatially isolated ecosystems, so these fragments play a key role in biodiversity conservation (Hermy 1994; Hermy et al 1999).…”

Visitor’s access to understorey vegetation in park forest stands results in the impoverishment of plant species composition and a reduction in habitat quality. The phenomenon of biotic homogenisation is typical in urban landscapes, but it can proceed differently depending on the scale, a detail that has not been observed in previous studies. This research was carried out in seven Warsaw parks (both public and restricted access). Thirty-four forested areas were randomly selected, some subjected to strong visitors’ pressure and some within restricted access areas, free of such impacts. The latter category included woodlands growing in old forest and secondary habitats. Public access to the study areas contributed to the disappearance of some forest species and their replacement by cosmopolitan non-forest species, leading to loss of floristic biodiversity in areas of high ecological importance at the city scale. Some human-induced factors, including soil compaction and changes in soil pH, moisture and capillary volume, were found to cause habitat changes that favoured native non-forest plants. Despite changes in species composition, the taxonomic similarity of understorey vegetation in both categories—public access and restricted access—was comparable. In a distance gradient of measurements taken around selected individual trees, there was found to be significant variation (in light, soil pH and compaction) affecting the quality and quantity of understorey vegetation (including rare species). In conclusion, the protection of rare forest species could be achieved by limiting access to forested areas, particularly in old forest fragments, and we highly recommend its consideration in the proposal of future park restoration plans.

“…This result was supported in part by other authors (Rowland et al 2005). Many studies have pointed out that vegetation was affected by logging activities, and they noticed a negative correlation between logging intensity and plant cover, species richness and species diversity (Sarah, Zhevelev 2007;Cakir et al 2010). Our results complete other studies on changes in plant populations and communities due to logging activities (Nuzzo 1995;Farris 1998;McMillan, Larson 2002;Rusterholz et al 2004).…”

Keivan Behjou F., Ghaffarzadeh Mollabashi O. (2017): Impact of logging intensity on stem density, basal area and biodiversity indices five years after logging in a Caspian hardwood forest. J. For. Sci., 63: 167-172.The aim of the present study was to analyse the impacts of different logging intensities after five years from logging including non-logged, low (3.4 felled stems per hectare), medium (5.2 felled stems per hectare) and high (7.1 felled stems per hectare) treatments on stem density, basal area, canopy cover, and forest biodiversity indices. The study area was located in northern Iran. Data was collected on a set of 120 circular plots with 5 m radius from both non-logged and logging areas. Stem density, basal area, and percentage of canopy cover were measured. Biodiversity study was done by measuring two diversity indices including Simpson's and Shannon-Wiener's, two richness indices including Margalef 's and Menhinick's and two evenness indices including Pielou's and Hill's indices. The results indicated that the treatment with the medium logging intensity was found to cause the highest amount of positive effects on stem density, basal area, and biodiversity indices. It is concluded that harvesting intensity should be limited to a medium level (approximately 5 felled trees per hectare) during each logging operation to improve forest biodiversity indices.
