“…Graminoids (Table ) had higher richness values in the BC position, which do not coincide with that found in high density old plantations of the region, where evergreen perennial herb and graminoid richness decreased significantly when compared with the shrubland (Giorgis et al., ). Therefore, our findings agree with those of other authors who have documented differences in biodiversity indicators according to the silvicultural management strategies applied in the plantations (Brockway & Outcalt, ; Greene et al., ; Jiménez et al., ). Finally, the PCA ordination (Figure ) was consistent with the results obtained by analysing differences between treatments in terms of site conditions and life forms.…”

Several studies (Brockway & Outcalt, ; Greene et al., ; Jiménez et al., ) have documented differences in biodiversity indicators according to the silvicultural management strategies applied in conifer plantations. In general, silvicultural practices such as thinning (which tends to open the canopy cover and reduce competition) promote an increase in diversity of plant species in the ground vegetation (French et al., ).…”

Question: What effects do low-density afforestation with Pinus elliottii have on the site conditions and plant diversity of the mountains of central Argentina? Location: Sierra de Comechingones, central Argentina.Methods: We studied the species richness and diversity and the physical and chemical properties of soils, in both the non-afforested steppe (US) and the understorey of P. elliottii silvopastoral systems (SPS). Measurements were performed on three plots located in US and 18 experimental plots located in SPS, which differ in tree density (150, 250 and 450 trees/ha), pruning (with/without) and position (below -UC -, or outside -BC -, the vertical projection of the tree crown). In each plot, we measured soil variables organic matter (OM), pH, electrical conductivity (EC), moisture content (RH) and relative proportion of coarse fragments; as well as photosynthetically active radiation that reached the ground surface (PAR i ). At the same time, a floristic survey was performed, consisting of 117 sampling plots distributed equally between treatments. Richness, diversity and evenness indices were calculated for each treatment.Then, we carried out a PCA in order to identify the differences in life forms and environmental variables across the treatments.Results: PAR i and pH were statistically significantly higher in US, while EC and RH were statistically significantly higher in SPS. Diversity indices did not differ significantly among the non-afforested steppe (US) and the patches between crowns (BC), but were significantly higher in both these treatments than below the crown (UC).The higher richness in some of the life forms and light availability clearly separated US from UC in the PCA. All the species of interest (endemic, N-fixing, medicinal, fodder) were found in the SPS. Conclusions:Our study indicates that the changes in site variables produced by lowdensity afforestation generate niches for some species and, simultaneously, constitute a barrier to others. However, the fact that diversity indices and the presence of the species of interest showed no differences among the between-crowns patches and the non-afforested steppe, highlights the complex environment-vegetation relationships that take place in this kind of system.

“…The ultimate goal of site preparation is to create a suitable growing environment that results in rapid reforestation. Vertebrate biodiversity response to stand establishment practices is strongly influenced by intensity of site preparation (e.g., White et al 1976;Johnson and Landers 2015;Enge and Marion 1986;Haeussler et al 1999;Lane et al 2011;Jones et al , 2010Iglay et al 2012b, Greene et al 2016, where intensity is typically described by the amount of exposed mineral soil, extent and intensity of vegetation suppression, or the type of site preparation (chemical, mechanical, both).…”

In the United States, intensively managed forests (IFM) comprise approximately 9% (27.9 million ha) of total forest area. These forests are primarily in highly productive areas and are managed primarily for wood and fiber production. Intensively managed forests provide both opportunities and constraints for conservation of vertebrate biodiversity. However, because a comprehensive review of these opportunities and limitations within the U.S. is lacking, we reviewed effects of typical silvicultural management regimes within IFM on terrestrial vertebrate species. The typical silvicultural regime in IFM includes practices associated with establishing forest management units (stands), weed control, intermediate thinning, and final harvest. Effects of IFM on vertebrate diversity are indirect through habitat modification. Terrestrial vertebrate responses to IFM are species-specific and directly linked to intensity and extent of habitat modification. Shorter crop tree rotations compress successional stages and limit development and recruitment of mature forest structures (e.g., snags, den/roost trees, coarse woody debris). During stand establishment, increased intensification of site preparation and weed control tends to result in lower vertebrate diversity. Generally, vertebrate

“…Although SMZs are generally not designed to conserve terrestrial wildlife associated with riparian ecosystems, they likely provide this secondary benefit for many species. Notably, most studies of SMZs focus on a few species or a single functional group, yet variation has been reported among species responses (i.e., birds, amphibians, reptiles, small mammals, and invertebrates) to riparian buffer characteristics (Marczak et al 2010, Greene et al 2016.…”

2019. Differential responses of amphibian and reptile assemblages to size of riparian buffers within managed forests. Ecological Applications 29(8):Abstract. Streamside management zones (i.e., riparian buffers; SMZs) are commonly implemented within managed forests to protect water quality but may also provide habitat for riparian-associated wildlife. Yet, little research has rigorously addressed the value of SMZs for wildlife, particularly for cryptic species such as amphibians and reptiles. Previous studies of herpetofauna within SMZs have focused on one or a few stream-associated species, and questions remain regarding variation among species or guilds and what role SMZs serve toward conservation of herpetofaunal diversity in managed forests. However, recent statistical advances have improved our ability to analyze large multi-species presence-absence data sets, accounting for low detection rates typical for some herpetofaunal species. Our study represents an extensive landscape-scale examination of herpetofaunal communities within SMZs using a multi-species occupancy approach. We conducted four replicate surveys at 102 headwater streams, spanning a gradient of SMZ widths and adjacent forest stand ages, within the Ouachita Mountains, Arkansas, USA. We used a hierarchical Bayesian community occupancy model to estimate species richness and species-specific occupancy responses to SMZ and overstory characteristics, accounting for variation in occupancy and detection attributable to site and sampling covariates. We documented high richness (37 species) within SMZs. Across the herpetofaunal community, occupancy and species richness were consistently positively associated with SMZ width, with maximum predicted richness of 30 species occurring at sites with buffers extending 51 m on either side of the stream. However, we documented considerable variation among groups and species within groups, underscoring the potential for different responses to forest management among taxa. Reptile predicted richness increased more rapidly up to SMZs of~35 m, whereas maximum salamander predicted richness was not seen until an SMZ width of 55 m. Estimated salamander richness was highest within SMZs embedded in mature managed pine stands and was higher in SMZs comprised of a deciduous or mixed overstory vs. a pine overstory. Compared to salamanders, more anuran species showed high mean estimated occupancy (>75%) at narrower SMZs (<30 m). Collectively, our results indicate that SMZs surrounding small first-order streams in intensively managed forests not only protect water quality, but also can support diverse amphibian and reptile communities.
