“…This paper will take a large scale and synoptic analysis of the pattern and degree of substitution in seagrass meadows, focusing on 17 Posidonia oceanica meadows of the Ligurian Sea (NW Mediterranean). An extensive use of ecological indices (Anselin et al, 1989) was made in order to explore the relationship between the meadow state of health and the degree of replacement by substitutes at a regional-wide spatial scale and to discuss whether the invasive species act as the drivers of community changes or merely as the passengers of the habitat degradation.…”

ABSTRACT1. The endemic seagrass Posidonia oceanica meadows in the Mediterranean Sea are presently facing invasion by alien algal species, especially where they are already showing signs of regression as a result of other stresses. Regressed meadows may be recolonized by native or alien macrophytes that take the place of P. oceanica.2. The pattern and degree of substitution by either native (Cymodocea nodosa and Caulerpa prolifera) or alien (Caulerpa taxifolia and C. racemosa) species in 17 P. oceanica meadows along the coast of Liguria (Italy, NW Mediterranean) were investigated. The invaders were found to be stronger colonizers, in terms of habitat occupancy within meadows, than the natives.3. A set of indices was used to quantify biological invasion within the seagrass ecosystem and to explore the relationship between the meadow's state of health and the replacement by substitutes. The ecological status of the receiving habitat was shown to play a major role in modulating the spread of substitutes.4. Substitutes are thought likely to act simply as passengers of habitat degradation in deep meadows, where previous regression has increased the likelihood of their colonization, but could be the drivers for P. oceanica loss in shallow ones, where they settled even in healthy meadows thus starting the process of regression. Long term monitoring and sustained maintenance of healthy P. oceanica meadows appear to be the most effective management tools to contain the risk of ecological substitution.

“…While different techniques for multi-criteria evaluation have been developed, the most commonly accepted method is Thomas Saaty's [34,35] Analytic Hierarchy Process (AHP), which has also been widely incorporated into different GIS applications to analyze aptitude [36,37]. The AHP first decomposes the decision problem into a hierarchy of subproblems.…”

Abstract:The analysis of past and present patterns of agrarian mountain areas allows researchers to characterize the influence of landscape heterogeneity on biodiversity, cultural heritage, and forest fire hazard. This process was mapped, quantified, and described through the use of digital mapping (GIS) and landscape indexes in a protected area in Alta Garrotxa (Catalonia, Spain). These areas require urgent management and modelling to provide alternative management scenarios, in order to maintain and recover habitats. A set of different scenarios have been designed using a multi-criteria evaluation and geospatial information available for the study area to identify the key areas for management action and to predict the potential effects on agricultural lands by prioritizing one or another management objective: biodiversity, landscape structure and perception, cultural heritage, fire hazard, and management cost. The observed progressive land abandonment of open areas with a small size and greater isolation will have a large impact on biodiversity and cultural heritage, and increase fire risk. Sustainable development will require planning objectives compatible with the conservation of biodiversity and the preservation of Mediterranean features with support for agricultural activities. This methodology can contribute to and be easily implemented by land managers, which could help to strengthen the link between managers and stakeholders.

“…However published literature describing AHP applications to natural resources is, surprisingly, still limited (Mendoza, 1997). Some of the published applications in natural resources are: forest management planning (Mendoza and Sprouse, 1989;Kuusipalo and Kangas, 1994); integration of biodiversity to forest planning (Kangas and Kuusipalo, 1993); environmental planning processes (Anselin et al, 1989;Varis, 1989); development of resource management plans for national parks ; and resource inventory and monitoring in national parks .…”

The problems existing in design of buer zones are analyzed, and a procedure for designing the buer zone of reserves is proposed. The Analytic Hierarchy Process (AHP) is applied to design the width of buer zone. The dierent importance of in¯uences in dierent sections around the reserve leads to dierent widths of buer zone being designated around the reserve. The method is illustrated by a case study, designing the buer zone for the Yancheng Biosphere Reserve, China. #
