In order to determine the relationship between physiographical factors and regeneration changes in forests, and to improve and model natural regeneration status, Gorazbon district in Kheyrod Forest was selected for the study. All available regeneration patches in the area were selected. To achieve spatial structure and quantify metrics related to regeneration patches, the analysis of landscape metrics was used. The results show that 692 regeneration patches were identified at the level of different directions. LAND Metric show the most regeneration percent is related to the western (9%), southern (8.66%), flat areas (8.33%), northern (5.68%) and eastern (4.73%), respectively. In total, the patch coverage level percentage was calculated in the landscape (8.31%). The results related to patch shape metric show that most shapes of patches follow polygon structures and do not have fixed shapes. Results related to the average area of the patch metric show that the average level of patches is between 4 and 5 R. The maximum and minimum distance between patches was observed in the survey between 39 and 520 m respectively. According to the results of the distance average between patch metric, the distribution of patches is random in the southern and western directions, flat areas and pile, but it is uniform in northern directions. It should be noted that the distribution and structure of patches in the northern directions has a better distribution and homogeneity than the other directions. Its canals are used as a natural regeneration model to follow the natural phenomena in forest sustainable management.

Criteria and indicators for sustainable forestry under Mediterranean conditions applicable in Spain at the forest management unit scale

2015

Aim of study: to identify criteria and indicators (C&I) of sustainable forest management (SFM) under Mediterranean conditions. The indicators are meant to monitor changes in the provision of ecosystem services at a local scale (forest management unit, FMU). We support that if a forest provides a bundle of ecosystem services its management can be considered sustainable; thus, we adjust C&I to an ecosystem services classification.Area of study: La Hunde y La Palomera, a public FMU in the region of Valencia (east of Spain), 100km southwest of the city of Valencia.Material and methods: first, a literature review of the following themes took part: SFM, features of Mediterranean forests, ecosystem services and C&I. Some C&I were proposed and, later on, a participatory process in Ayora, the municipality where the mentioned FMU is located, was carried out with different stakeholders (forestry professionals, users for recreation, hunters, environmentalists and professionals of cultural and rural development activities) in order for them to value the C&I proposed according to their management preferences for La Hunde y La Palomera.Research highlights:- 15 criteria and 133 indicators were identified: a balance has been achieved among economic, social and ecological concerns.- People value the ecological issues associated to forestry on top and the economic ones at the bottom.- Results suggest that SFM under Mediterranean conditions is based on more than one product and on the provision of several ecosystem services.Keywords: Sustainable forest management; ecosystem services; local scale, literature review, participation.

“…During the past several decades, researchers have developed new approaches for quantifying biotic sensitivity to ecosystem degradation (Niemi and McDonald 2004). Although some ecologists are skeptical about the utility or validity of indicator species (Simberloff 1999), the use of biotic indicators has grown steadily because of a demand for accountability of resource management policies and land use practices (Karr 1987, Croonquist and Brooks 1991, Karr and Chu 1997, Carignan and Villard 2002, Niemi and McDonald 2004, Kotwal et al 2008.…”

Sensitivity of breeding birds to the “human footprint” in western Great Lakes forest landscapes

et al. 2015

Abstract. Breeding birds in forest ecosystems are generally diverse, habitat selective, and easily sampled. Because they must integrate environmental variables over space and time, local populations of forest birds (like other animal and plant taxa) may provide meaningful signals of local forest health or degradation. We evaluated 949 breeding bird surveys in areas ranging from degraded urban/suburban forest remnants to relatively pristine old growth forests in the western Laurentian Great Lakes region of North America. The ''human footprint'' across this landscape was represented by a one-dimensional numeric gradient derived from land cover variables, forest fragmentation metrics, and publicly available data on housing density and transportation corridors. We used an iterative, maximum likelihood approach to quantify species-specific responses to this human disturbance gradient. Many species showed significant directional responses, consistent with known life history attributes. Other species were most commonly detected at intermediate levels of anthropogenic disturbance, yielding unimodal responses. Relationships between the ''human footprint'' and occurrences of 38 bird species were illustrated by general Gaussian functions that represented both unidirectional and unimodal patterns. These biotic response (BR) functions were combined into a bird-based index of ecological condition (IEC) ranging from 0 (maximally degraded) to 10 (minimally degraded). We described a successful application of the IEC method at the Wild Rivers Legacy Forest (WRLF), a .260 km 2 conservation landscape in northeastern Wisconsin, USA, managed primarily under a working forest conservation easement established in 2006. In general, areas within the WRLF yielded high IEC values (7.0-9.0), but nearby forest areas not under the conservation easement were characterized by significantly lower IEC values based on breeding bird assemblages.
