Despite the heavily fragmented nature of the world’s forests (1), the response of forest carbon (C) and nitrogen (N) dynamics to edge effects is understudied. Contrasting our findings that edge effects did not alter soil C and N storage of temperate forests within residential landscapes in New England (2), Remy et al. (3) point to their work showing that belowground C andN storage increases nea...
measuring the perceived quality of residential environments is one of the fields of inquiry for housing environment researches. most of the data on the perceived quality of residential environments are restricted to existing and large cities experiences. however, little attention has been paid to new town residential complexes particularly in third world countries. residential and neighborhood ...
One of the aspects of city dynamism is households’ movement from one residential neighborhood to other ones inside the city. These movements that affect city structure have various reasons.

TThe forest plantation strategy is to do with the identification of the most appropriate zones and the areas that are most suitable for different species. However, the success of this strategy requires the precise determination of the species ecological demands and the evaluation of the land before the establishment of the plantation. The purpose of this study is to assess the ecological capabi...
we studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, langa forest, watershed 36: kazemrood) of the caspian beech forest in n iran. two transects, each 2 m wide, were laid along the longest (n-s) and shortest (e-w) axis of each gap. five micro sample plots, each 4 m2, were established: one at the center, and one at each corner. q...

Forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. Traditional methods such as field surveys are almost time-consuming and cost-intensive. Improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. This research co...
