Background: During the past decade, phenomenon of Oak decline has affected valuable Zagros Forests in western Iran. Quercus brantii as most important tree species these forests been damaged more than any other species. Many factors are involved this phenomenon. The purpose study was to identify areas with high potential for and determine affecting it. In study, using multi-criteria evaluation m...
Investigation on Seedling Emergence from Direct Seeding of Quercus Persica, Pistacia Atlantica and Acer Cineracens in Natural Conditions Ilam, Dalab Forests
Fire-maintained woodlands and savannas are important ecosystems for vertebrates in many regions of the world. These ecosystems are being restored by forest managers, but little information exists on herpetofaunal responses to this restoration in areas dominated by shortleaf pine (Pinus echinata). We compared habitat characteristics and herpetofaunal communities in restored pine woodlands to rel...
Hardwood forests are principal features of the landscape of both California and Britain and indigenous oak species are important components. In both locales these “oak woodlands” have historically provided a wide variety of commercial and non-commercial products and benefits and are deeply valued and appreciated by those who live in and around them. However, human-induced impacts have reduced t...
The miombo woodlands of eastern, central and southern Africa are some of the most extensive dry forests in Africa. They supply a myriad of products and services for local populations, governments and the private sector, the main stakeholders. Planning the management and use of the woodlands by many and diverse stakeholders who often have conflicting interests in the woodlands continues to be a ...
The quick and accurate extraction of information on woodland resources and distributions using remote sensing technology is a key step in the management, protection, and sustainable use of woodlands. This paper presents a low-cost and high-precision extraction method for large woodland areas based on the fractal features of the Moderate Resolution Imaging Spectroradiometer (MODIS) normalized di...
In this paper we engage with debates concerning people and their contact with the natural environment as part of everyday life drawing on Irwin's ideas of co-construction and Gibson's theory of affordances. We focus on peri-urban woodlands in England as important places where people can interact with nature for health and well-being. Qualitative data were collected in situ via walks in the wood...
Quantitative analysis of household use of miombo resources is limited, and detailed accounts of a full range of environmental resources are scanty. The present manuscript aims to (a) quantify the contribution of miombo woodlands to the household economy; (b) assess the role of miombo woodlands as safety nets in the face of household level economic shocks; and (c) identify the socio-economic det...
Many crop pests rely on resources out of crop fields; understanding how they colonize the fields is an important factor to develop integrated pest management. In particular, the time of crop colonization and damage severity might be determined by pest movements between fields and non-crop areas. Notably, the pollen beetle, Brassicogethes aeneus, previously named Meligethes aeneus, one of the mo...
