Recent model projections and many research results across the world suggest that forests could be significant carbon sinks or sources in the future, contributing in a such a way to global warming mitigation. Conversion of coppice forest to high forest may play an important role towards this direction. This study deals with the estimation of biomass...
In the past few years, the continuous expansion of urban development has created mixed forested, agricultural, and urban areas. These areas are called the wildland–urban interface (WUI), and they are characterized by increased human activities and land-use conversion, and they usually contribute to a high risk of wildfire occurrence. In the case of...
Forests host important plant biodiversity. Nevertheless, due to climate change and human disturbances, the floristic quality of forest ecosystems is degraded. Greek peri-urban forests biodiversity is threatened by anthropogenic activities such as forest fragmentation, pollution, garbage, etc. Measurement of biodiversity status and the floristic qua...
Floodplain forest ecosystems are considered important ecosystems for their high ecological and economical values and functions.

Κατά την περίοδο της πανδημίας του covid-19 και των μέτρων για την αντιμετώπιση της (από 3/2020 έως και τον 5/2021) ο μαζικός τουρισμός κλονίστηκε. Οι ανάγκες για κοινωνική αποστασιοποίηση ευνόησαν τις επισκέψεις σε περιοχές φυσικού κάλους και στα δάση, όπου ο οικοτουρισμός με τα ιδιαίτερα χαρακτηριστικά του (επισκέψεις στην ύπαιθρο από μικρές ομάδ...
Είναι γενικά αποδεκτό ότι τα δάση συμβάλλουν στη δέσμευση του άνθρακα και στη μείωση της συγκέντρωσης του διοξειδίου του άνθρακα της ατμόσφαιρας, στο οποίο αποδίδεται κατά κύριο λόγο η υπερθέρμανση του πλανήτη. Παρόλη όμως τη γενική παραδοχή, ο ακριβής προσδιορισμός των ποσοτήτων άνθρακα που δεσμεύονται στα δασικά οικοσυστήματα είναι μια δύσκολη δι...
