“…The connectivity between patches is relevant when studying the structure of the landscape since proximity influences the gene flow between forest patches and, therefore, the maintenance of the biotic community PINHEIRO, 1998). In this sense, the connectivity index has been applied to guide the decision-making process on conservation and restoration actions, through the dispersal ability of the species, for example, (CROUZEILLES et al, 2014;DALLOZ et al, 2017;TAMBOSI;METZGER, 2013) and creating ecological corridors in the Atlantic Forest (SANTOS et al 2018). The forest fragmentation observed in this study directly affected the increasing patch connectivity index.…”

Multitemporal spatial analysis for monitoring land cover and use is an important tool for understanding the evolutionary dynamics of a certain region. This study aims at determining and using landscape ecology indices to map and analyze the forest landscape structure in the Barra Seca River basin, an area of 2,216.56 km 2 , in northern Espírito Santo, in 1985, 1996, 2006 and 2016. The forest patches composing the landscape were isolated and classified by area size using remote sensing techniques by supervised classification and the Bhattacharya algorithm. The landscape metrics and indices in the Patch Analyst extension and

“…The positive and significant correlation of micronutrients with clay suggested that these nutrients mainly reside in the clay fraction of these soils [34]. The elevation and values of flow vectors, a direct relation between them and with the clay content and, consequently, indirect with the micronutrients of the soil.…”

“…Thus, site specific management (SSM) seeks to identify, analyze, and manage spatial and temporal variability within fields in order to optimize profitability, sustainability and environmental protection [33]. For example, in Brazil, other authors used this strategy to create ecological corridors [34] or aquatic environments such as estuaries [35]. However, in soil science, this application remains a challenge due to the correct utilization of soil attributes with a low variability over the time that allows us reaching a successful delineation of management zones.…”

The proper delineation of site-specific management zones is very important in the agricultural land management of potentially degraded areas. There is a necessity for the development of prospective tools in management plans to correctly understand the land degradation processes. In order to accomplish this, we present a pedo-geomorphological approach using soil texture, land elevation and flow vector aspects to distinguish different management zones and to discretize soil micronutrients. To achieve this goal, we conducted the study in the Neyshabur plain, Northeast Iran. For data collection, grid sampling (500 × 500 m) was used with 70 specific points. Soil samples were collected in triplicates from various sites as composite samples (0-30 cm) to analyse clay, Zn, Mn, Cu and Fe. Using the altitude information (obtained with GPS at each sampling point), flow vectors were also modelled for all selected points. Based on the values of altitude, flow vectors and clay, management zones were delimited using geographic information systems. The best data organization was obtained from the combination of clay + elevation + flow vector attributes, generating two different management zones. In this circumstance, the lowest fuzzy performance index (FPI) and modified partition entropy (MPE) values were generated. It can be observed that the management zone 1 (MZ1) is located in the areas with a lower elevation and higher content of clay. On the other hand, the MZ2 was characterized by areas with a higher elevation and lower clay content. This study concluded that the design of management zones, using pedo-geomorphological information could reduce the time and cost of sampling necessary to assess potentially degraded areas of land. reforestation or geotextiles are also successfully applied. However [10,11], the drastic decline in yield or wood production and the increase in soil degradation processes can also be attributed to the intensification of its cultivation or exploitation, as well as the imbalance in soil nutrient management and physical properties [12,13].It is unusual to assess soil degradation or delimitate land management zones via clay, Zn, Mn, Cu and Fe. However, recent research conducted by [14] in India demonstrated that micronutrient deficiency in intensively cultivated regions may be associated with a low organic availability and excessive reliance on chemical fertilizers. In Northern Greece, [15] assessed Fe, Mn, Zn and Cu bioavailability their correlation with foliar micronutrient concentrations in mature organic olive orchards, highlighting the key role of organic matter to sustain metal uptake by olive trees. However, it is not common to see clear examples showing how these data on micronutrients can be a basis for a land management planning tool to achieve land degradation neutrality. Usually, other robust indicators such as cation exchange capacity, base saturation, the content of soil organic matter, but in several cases, only a few data about soil chemical properties such as micronutrients are analysed...

“…The establishment of ecological corridors between nature reserves can connect isolated habitats and reduce the rate of species extinction. The paths for wildlife movement can be defined as ecological corridors (Santos et al, 2018). There are various benefits of building ecological corridors such as, protecting the diversity of species, diffusing the animals (Merriam & Lanoue, 1990), increasing the exchange of genes, and reducing the risk of extinction (Kupfer & Malanson, 1993).…”

Abstract. In biodiversity conservation, ecological corridors are assumed to increase landscape-level connectivity and to enhance the viability of otherwise isolated wildlife populations. Mapping these corridors serves as a feasible method to support forest management efforts in pinpointing areas to give special attention to. Here, we assess the current forest presence in the 3,000 hectare Mt. Lantoy, Key Biodiversity Area in Argao, Cebu and present potential forest corridors that could enhance the canopy cover of the current protected area. We present a method to map the potential corridors through the identification of the forest patches obtained from the global forest cover dataset and the creation of a species distribution model for the black shama, an endemic bird species in Cebu island and a great biodiversity indicator for the area. Our ecological corridors were acquired through the sum of the cost distance rasters obtained from the weighted overlay and cost surface tools of the black shama habitat suitability model. With the obtained corridors from the study, four potential forest corridors/ extensions were identified connecting five different forest patches. These corridors have areas that range from 0.47–2.17 square kilometers, with a potential to increase the forest cover in the KBA to more than 33% after corridor modelling.
