The management of landscapes for biological conservation and ecologically sustainable natural resource use are crucial global issues. Research for over two decades has resulted in a large literature, yet there is little consensus on the applicability or even the existence of general principles or broad considerations that could guide landscape conservation. We assess six major themes in the eco...
Analyzing evolution characteristics of landscape ecological risk patterns would help establish ecological risk early warning mechanism, reduce the ecological risk probability and promote coastal landscape pattern optimization. In this study, landscape pattern indices were first calculated by using multitemporal Landsat TM images acquired in years 1990, 2000 and 2010, then landscape ecological r...
Managing landscape-scale environmental problems, such as biological invasions, can be facilitated by integrating realistic geospatial models with user-friendly interfaces that stakeholders can use to make critical management decisions. However, gaps between scientific theory and application have typically limited opportunities for model-based knowledge to reach the stakeholders responsible for ...
Contemporary Australian rangeland management is characterised by concurrent processes of a continuing intensification of land management practices and simplification of landscape ecological processes. This dual characteristic is associated with increasing levels of potential conflict between land management practices that promote improved economic performance of rangeland enterprises at the app...
Relevant management decisions are directly subjected to our ability to characterize landscape pattern: the amount and arrangement of spatial variability. The primary objectives of our project were (1) to develop new exploratory spatial data analysis (ESDA) methods to evaluate and quantify landscape spatial heterogeneity across spatial scales, and (2) to assess the sensitivity of widely used lan...
Biological invasions are not only a major threat to biodiversity, they also have major impacts on local economies and agricultural production systems. Once established, the connection of local populations into metapopulation networks facilitates dispersal at landscape scales, generating spatial dynamics that can impact the outcome of pest-management actions. Much planning goes into landscape-sc...
Small mammals provide ecosystem services, acting, for example, as pollinators and seed dispersers. In addition, they are also disease reservoirs that can be detrimental to human health and they can also act as crop pests. Knowledge of their dispersal preferences is therefore useful for population management and landscape planning. Genetic data were used alongside landscape data to examine the i...
This paper is an attempt to help in the area of regional management. The quality of life of people in cities and villages is dependent of quality of regional management, because the landscape and environment are, today, the main aspects of quality of life. The shortage of knowledge can be problem and the reasons of insufficiently care about landscape. But, especially in the small villages, solu...
A landscape model (LEEMATH) to evaluate effects of management impacts on timber and wildlife habitat
Managing forest resources for sustainability requires the successful integration of economic and ecological goals. To attain such integration, land managers need decision support tools that incorporate science, land-use strategies, and policy options to assess resources sustainabil i ty at large scales. Landscape Evaluation of Effects of Management Activit ies on Timber and Habitat (LEEMATH) is...
