Abstract<br />

SISPARES is a system devoted to study the ecological evolution of the Spanish Rural<br />

<strong>L<strong>and</strong>scapes</strong> including their characterisation, classification, <strong>and</strong> recent past <strong>and</strong> future changes. It<br />

is based on a sampling network of 215 permanent 4x4 km plots surveyed by using aerial<br />

photographs of three dates: 1956, 1984 <strong>and</strong> 1998. Currently, a new survey is going on. The<br />

network design was based on an environmental stratification of Spain well linked to the<br />

European Environmental Stratification.<br />

<strong>Forest</strong> L<strong>and</strong>scape Vulnerability (FLV) is defined as the risk of human disturbance, especially<br />

forest fires. We assessed FLV using an index based on <strong>Forest</strong> L<strong>and</strong>scape Fragility (FLF)<br />

weighted by Road Accessibility. FLF is defined as the risk of l<strong>and</strong>scape disturbance caused by a<br />

high degree of interspersion <strong>and</strong> juxtaposition between patches of forest <strong>and</strong> non forest l<strong>and</strong><br />

uses: The non forest l<strong>and</strong> uses, such urban, crop <strong>and</strong> managed grassl<strong>and</strong>, are considered as<br />

potential sources of human disturbances, for the forest l<strong>and</strong> use patches, including woodl<strong>and</strong>,<br />

“matorral”, “dehesa”, tree plantation <strong>and</strong> riparian woodl<strong>and</strong>.<br />

From 1956 till 1998, a significant increase of FLV has been observed in SISPARES l<strong>and</strong>scape<br />

plots. This increase is related to the increment of forest fires in Spain during the last 40 years.<br />

Keywords: L<strong>and</strong>scape, monitoring, vulnerability, SISPARES system, Spain<br />

1. Introduction<br />

L<strong>and</strong>scape vulnerability is defined as the risk of severe disturbances <strong>and</strong> could be consider as a<br />

character of l<strong>and</strong>scape patterns (composition <strong>and</strong> configuration). In recent years, l<strong>and</strong>scape<br />

character assessment in Europe has become central to sustainable development <strong>and</strong> the<br />

management of l<strong>and</strong>. It is recognised as an important tool for policy stakeholders, which<br />

provides them with quantitative <strong>and</strong> qualitative evidence to reach a dynamic management,<br />

adjustable to new dem<strong>and</strong>s of regional identity (Washer 2005). But only, Denmark (Nordic<br />

Council of Ministers 1987), Austria (Wrbka et al. 1999) <strong>and</strong> Spain (Elena-Rosselló et al. 2005)<br />

have developed national approaches for delimitation <strong>and</strong> mapping local spatial units on the basis<br />

of a range of l<strong>and</strong>scape features (geophysical, cultural <strong>and</strong> historic, perception <strong>and</strong> aesthetics<br />

<strong>and</strong> natural value) as a basis for vulnerability assessment. However, in many other countries all<br />

over the world, local approaches exist <strong>and</strong> some of them have been specifically designed to<br />

evaluate l<strong>and</strong>scape vulnerability to forest fire (e.g. Preston et al. 2009, Sorrensen 2009). They<br />

are important tools for preventing the risk of forest fire.<br />
