To inspire landscape ecologists in developing research for a more sustainable future, we highlight some of the key points raised there. We emphasize challenges that have been identified in sustainability science that we consider particularly relevant for landscape sustainability. Then we describe how landscape ecology could enrich sustainability science. Finally, we propose five topics for landscape ecology research to advance landscape sustainability science. Key challenges in sustainability science sustainability (Ekins et al. 2003;Wu2013) may be used to deepen understanding of what a sustainable Reflective papers on the progress in sustainability landscape may be. research have produced important insights in key features and enabling factors that determine how Changes to make local landscapes more science may contribute to transitions towards sustain- sustainable have implications for landscapes ability (Lang et al. 2012; Miller 2013; Miller et al. elsewhere 2014; Fischer et al. 2015; Balvanera et al. 2017 and Scha¨pke et al. 2017).

Cascading effects of fire exclusion in the Rocky Mountain ecosystems: a literature review. General Technical Report. RMRS- GTR-91. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 24 p. The health of many Rocky Mountain ecosystems is in decline because of the policy of excluding fire in the management of these ecosystems. Fire exclusion has actually made it more difficult to fight fires, and this poses greater risks to the people who fight fires and for those who live in and around Rocky Mountain forests and rangelands. This paper discusses the extent of fire exclusion in the Rocky Mountains, then details the diverse and cascading effects of suppressing fires in the Rocky Mountain landscape by spatial scale, ecosystem characteristic, and vegetation type. Also discussed are the varied effects of fire exclusion on some important, keystone ecosystems and human concerns. Keywords: wildland fire, fire exclusion, fire effects, landscape ecology Research Summary Since the early 1930s, fire suppression programs in the United States and Canada successfully reduced wildland fires in many Rocky Mountain ecosystems. This lack of fires has created forest and range landscapes with atypical accumulations of fuels that pose a hazard to many ecosystem characteristics.

  • Applying Landscape Ecology in Biological Conservation
    Kevin J. Gutzwiller Editor Applying Landscape Ecology in Biological Conservation With a Foreword by Richard T.T. Foman With 62 Figures, 2 in Full Color Springer Human Conversion of Terrestrial Habitats PETERAUGUST, LOUIS IVERSON, AND JARUNEENUGRANAD 12.1 Introduction In this chapter, we describe how human activities change the abundance and qual- ity of terrestrial habitats and discuss the ecological implications of these changes for biota. We begin by identifying fundamental principles associated with human conversion of terrestrial habitats and how fauna and flora respond to habitat con- version. We present a number of examples of how landscape ecologists and con- servation biologists use these basic principles of land-cover change to develop management strategies to minimize ecological impacts from habitat loss. Next, we discuss principles for applying landscape ecology. We identify major voids in ecological theory and existing data that need to be filled for land managers to be better prepared to apply the principles of landscape ecology to biological conser- vation. Finally, we suggest research approaches that may be used to fill knowl- edge gaps. Although social and economic considerations are fundamental to land- cover change dynamics (Riebsame et al. 1994). detailed discussion of these factors is beyond the scope of this book; therefore, we focus our remarks on the ecological aspects of human conversion of terrestrial habitats. 12.2 Concepts, Principles, and Emerging Ideas Human disturbance is the most significant contemporary agent of change in ter- restrial ecosystems (Forman 1995). The rates with which natural habitats are lost, disturbed landscapes are created, species go extinct, and ecosystem processes are altered are higher now than they have been since the last cataclysmic event that impacted the planet 50 million years ago (Fastovsky and Weishampel 1996).

Box 874501, Tempe, AZ 85287, USA Abstract: Biodiversity is the basis for ecosystem goods and services that provide for human survival and prosperity. With a rapidly increasing human population and its demands for natural resources, landscapes are being fragmented, habitats are being destroyed, and biodiversity is declining. How can biodiversity be effec- tively conserved in the face of increasing human pressures? In this paper, I review changing perspectives on biodiversity conservation, and discuss their relevance to the practice of biodiversity conservation. The major points include: The notion of balance of nature is a myth rather than a scientific concept; the theory of island biogeography is useful heuristically but flawed practically; the SLOSS debate is intriguing in theory but ir- relevant in reality; the concept of minimum viable population and population viability analysis are useful, but technically inefficient and conceptually inadequate; metapopulation theory is mathematically elegant but ecologically oversimplistic; and integrative perspectives and approaches for biodiversity conservation are needed that incorporate insights from landscape ecology and sustainability science. I further discuss some key principles for regional conservation planning, and argue that the long-term success of biodiversity conservation in any region will ultimately depend on the economic and social sustainability of that region.

It is also very diverse, with different authors measuring fragmentation in dif- ferent ways and, as a consequence, drawing different conclusions regarding both the magnitude and direction of its effects. Habitat fragmentation is usually defined as a landscape-scale process involving both habitat loss and the breaking apart of habi- tat. Results of empirical studies of habitat fragmentation are often difficult to inter- pret because (a) many researchers measure fragmentation at the patch scale, not the landscape scale and (b) most researchers measure fragmentation in ways that do not distinguish between habitat loss and habitat fragmentation per se, i.e., the breaking apart of habitat after controlling for habitat loss. Empirical studies to date suggest that habitat loss has large, consistently negative effects on biodiversity. Habitat frag- mentation per se has much weaker effects on biodiversity that are at least as likely to be positive as negative.
