Landscape ecology has been featured with patch-corridor-matrix Landscape ecology has been featured with patch-corridor-matrix dogma -- a landscape is composed of multiple ecosystems. It is dogma -- a landscape is composed of multiple ecosystems. It is theorized that new structural and functional features would theorized that new structural and functional features would emerge when >2 ecosystems are placed togetheremerge when >2 ecosystems are placed together

Landscape StructureLandscape Structure: patch-corridor-edge-matrix framework (FRAGSTATS, Fractals, Wavelet, Semivariance/Kriging, etc.)
• Patch Patterns• Edges and AEI• Roads and Streams• Fragmentations
Landscape ProcessLandscape Process: movements of materials, energy and species across landscape
Landscape DynamicsLandscape Dynamics: change over time
Landscape ModelsLandscape Models: HARVEST, Neutral Model, Moose, Tree2.0, LANDIS, etc.
Landscape ManagementLandscape Management: mimicking natural processes and arrange land mosaics in time and space

Landscape is an area that is spatially heterogeneous in at least one factor of interest.
Landscape Ecology emphasizes the interaction between spatial pattern and ecological processes — that is, the causes and consequences of spatial heterogeneity across a range of scales (Turner et al. 2000) .
•Not a science
•Broader scales (mostly spatial)
•Multiple ecosystems, their spatial arrangement and interactions
•Applied scientific discipline
•Multidisciplinary

Tress et al. (2005)
The process of generating new knowledge comes full circle only when scientific understanding has been integrated into management and lessons from application are transferred back to validate or inform research studies. It is through this complete process that theories emerge.
