Why are Cultural Landscapes of Various Values? Thinking About Heritage Landscape Evaluation and Monitoring Tools
Sofia Capelo, Filipe Themudo Barata, José Manuel de Mascarenhas
Journal of Landscape Ecology , 2011, DOI: 10.2478/v10285-012-0030-3
Abstract: The aim of this paper is to contribute towards the successful management of heritage landscapes. Many cultural landscapes represent high heritage value and should be classified as heritage landscapes; therefore, special tools should be considered to be used in managing them. These landscapes should be evaluated according to heritage science criteria and good practice guidelines should be established. Several useful heritage landscape evaluation criteria were identified and characterised, and their relative importance was analysed, enabling the establishment of a heritage value hierarchy by means of a weighted linear combination. This is significant in the context of land management measures for countryside valorization promoting rural development. However, this approach also requires awareness of the link between the present cultural landscape and the history of the people that have interacted with the area involved. This is also important for the establishment of a priority ranking system for monitoring criteria indicators. A method for doing this is also proposed by the authors.
Monitoring of Biodiversity Changes in the Landscape Scale

Abstract: The monitoring and evaluation of changes in biodiversity is a subject for many biological and ecological disciplines. Biodiversity loss has become a social and political issue over the last few decades, and protection of biological diversity has emerged as one of the main subjects within national nature conservation policies as well as international conventions, conservation targets and political programmes (e.g. the Convention on Biological Diversity, Target 2010, SEBI 2010, CITES, Ramsar Convention, European Landscape Convention). The establishment of a monitoring scheme based on an appropriate set of indicators is vital for precise assessment of the effectiveness of measures applied within biodiversity protection (e.g. action plans for endangered species, agro-environmental and landscape protection programmes). Many indicators of biodiversity change have been proposed, but their representativeness and applicability frequently suffer from poor available data or local circumstances. The concept of species and landscape diversity evaluation using a fixed set of indicators has been developing in other European countries for some two decades, but this approach is still sporadic in the Czech Republic. This paper provides a review of the current state of this topic in the Czech Republic, discusses the concept of establishing a future national biodiversity monitoring network, and proposes a self-contained set of indicators covering all organizational and spatial levels. These proposals will enable scientifically based and sufficiently accurate evaluation of existing trends in biodiversity and its projection into the future based on foreseeable land-use changes.
A FOCUS ON THE LANDSCAPE MOSAICS: VEGETATION MAP OF “SERRA ROCCA CHIARANO – MONTE GRECO” S.C.I (ABRUZZO, CENTRAL APENNINES)

Annali di Botanica , 2011,
Abstract: Aim of this paper is to produce a GIS vegetation map of a high mountain area in Central Apennines applying the landscape ecological approach. The study area is Greco Mountain and Rocca Chiarano mountain ridge (Abruzzo, Central Italy), a calcareous system with very high biodiversity, designated as a Site of Community Importance in the frame of the Directive 92/43/EEC. 120 phytosociological relevés, sampled in 2005-2009 from May to October, were subjected to Cluster Analysis and 18 vegetation types, at the association level, have been distinguished. Ten of these associations are not represented in the vegetation map, due to their small-scale extent. Two alternative methods for vegetation mapping of the area, i.e. the standard synphytosociological and the landscape mosaic approach are briefly discussed. The former cannot be applied to the study area due to recent very intensive disturbance and ongoing rapid dynamics. The mosaic types represented in the map have been individuated on the basis of the occurrence of dominant species. Two mosaic categories have been identified: morphological and dynamic mosaic resulting from the different importance of natural factors vs. anthropogenic disturbance. Advantages and usefulness of the mapping approach adopted here are discussed as tools to detect, describe and represent complexity of ecosystem relationships.
Agriculture and land management: the landscape monitoring system in Tuscany
Mauro Agnoletti,Valentina Marinai
Italian Journal of Agronomy , 2011, DOI: 10.4081/ija.2009.s3.53
Abstract: With respect to the reduced weight in the Gross National Product (GDP) and the continuous decrease in manpower which has been recorded in the last decades, an important role is recognized to the rural sector in the current developmetn model which justify the heavy financial committment of Europe and Italy to sustain european agriculture.Within this role, land preservation has an important role for the sector competitiveness, the rural space quality and the citizen’s life quality, and this role is nowadays recognized even by the politics for landscape defined for the Piano strategico nazionale 2007-20131. Both action definitions and planning and development of landscape resources firstly require to define landscape monitoring systems pointing out trends, and critical and strength points represented by the great historical and environmental differences of Italian landscapes. This study is a synthesis of the results from a 5 year project aimed to the definition of a landscape monitoring system in Tuscany, ranging from 1800 and 2000 and based on study areas covering around 1% of the regional territory, which will soon be implemented. The first recorded results show a strong decrease of landscape diversity (40-50%) in the investigated time period. This study want to be an example for the implementation of the future monitoring system of this resource.

环境科学学报(英文版) , 1999,
Abstract: This work sets out to simulate landscape model of Mu Us Desert in Inner Mongolia Autonomous Region of China at different spatial resolution using remote sensing images and distinguished landscape heterogeneity among different spatial resolutions. Landscape models were created from classification image of SPOT satellite data with 20m resolution and NOAA data with 1 km resolution. This study created landscape models of different scales by resampling the SPOT classified image using majority rule. The pixel resolution was increased from the finest scale of 20m by 20m up to 1000m by 1000m that was the coarsest spatial resolution. The Shannon diversity index was used to compare landscape models between different scales. At the finer scale the verify small patches such as deciduous forest, shrub and reedswamp with high vegetation coverage set on matrices with low vegetation cover (moving sand dune and sparse grassland) were verified. Broadening of scale resulted to the loss of small patches and at 1000m resolution, matrix classes were dominant. At 1km resolution of NOAA data, the matrix classes which greatly related to the topography of Mu Us Desert were detected. Diversity index decreased during scale broadening and the difference between SPOT 1km scale model and AVHRR data was not significant. The results showed that SPOT 20m model is good for the use of ecotone oriented revegetation planning, and NOAA 1km model is good for the seasonal and annual monitoring of each landscape unit, and revegetation planning at the regional level.
