Spatial Origin & Reclamation of Landuse Footprints

This module makes it possible to define the future spatial distribution of each land use footprint among landscape types.  Landscape types in which footprints are permitted can be identified.  Within eligible landscape types, footprints may be distributed randomly, proportionally, or in a user-defined fashion.  It is possible to pause a simulation and change the distribution of new land use footprints among landscape types, providing greater flexibility in evaluating the influence of the spatial distribution of footprints.  After footprints have reached the end of their defined lifespan, it is possible to define a reclamation trajectory, returning each footprint type to the landscape type from which it came or reclaiming footprints to landscape types in a proportional manner, or by directing footprints to specific landscape types.  After footprints are reclaimed, it is possible to specify whether they contain invasive plants.  This panel allows the user to define the spatial distribution of each unfolding landuse footprint on the landscape types in the land base.

Table inputs

1.  Can a given landscape type receive land use footprints?

For each landscape type, enter '1' if land use footprints are permitted, '0' if they are not permitted.

2a.  Footprint origin strategy

For each type of land use footprint, enter 1, 2, or 3 as follows:
 1 = Footprints added to the land base during the simulation period are randomly distributed among landscape types in which the footprint is permitted (see Table 1).
 2 = Footprints added to the land base during the simulation period are distributed among landscape types in which the footprint is permitted (see Table 1) in a manner proportional to its distribution in the initial land base.
 3 = Footprints are added to the land base during the simulation period in a user-directed manner (see Table 6).

2b.  Footprint origin strategy

For each type of land use footprint, enter 1, 2, 3 or 4 as follows:
 1 = Growth of the footprint during the simulation period is expressed in area (ha)
 2 = Growth of the footprint during the simulation period is expressed in length (km)
 3 = Growth of the footprint during the simulation period is expressed in proportional change
 4 = Growth of the footprint during the simulation period is expressed in the number of units

3.  Footprint reclamation destination strategy

For each type of land use footprint, enter 1, 2, or 3 as follows:
 1 = Footprints are reclaimed to their original landscape types
 2 = Footprints are reclaimed to landscape types in proportions equal to the proportion of each landscape type in the land base.
 3 = Footprints are reclaimed to landscape types according to a user-defined distribution among landscape types.

4.  Switches for width-modified footprint lifespan

For each type of land use footprint, enter '1' if the lifespan of the footprint is modified by its width; '0' if it is not.

5.  Footprint lifespan strategy

For each type of land use footprint in each landscape type, enter 1, 2 or 3 as follows:
0 = Footprint is permanent and is never reclaimed
1 = Footprint is reclaimed immediately
2 = Footprint lifespan is based on a user-defined average lifespan

6.  User directed origin of footprints among landscape types

For each type of land use footprint, enter the proportion (0 - 1) of footprint area added during each year of the simulation period that is built on each landscape type.  Note that it is possible to pause the model during a simulation, change the proportional distribution of new land use footprints among landscape types, then resume the simulation run.  This makes it possible to evaluate the consequences of adjusting the spatial distribution of land use footprints during a simulation period.

7.  User directed reclamation of footprints among landscape types

For each type of land use footprint, enter the proportion (0 - 1) of footprint area reclaimed during each year of the simulation period that is reclaimed to each landscape type.  Note that it is possible to pause the model during a simulation, change the proportional distribution of reclaimed land use footprints among landscape types, then resume the simulation run.  This makes it possible to evaluate the consequences of adjusting the spatial distribution of land use footprints during a simulation period.

8.  On which landscape types do reclaimed footprints contain invasive plants?

For each landscape type, enter '1' if reclaimed footprints contain invasive plants.  Enter '0' if footprints are fully reclaimed to native cover.

9.  Which footprints are reclaimed by fire?

For each footprint type, enter "1" if the footprint is reclaimed after fire; '0' if it is not.

10.  Percent of initial footprint immediately reclaimed

For each footprint type, enter the proportion (0 - 1) of footprint present at the start of the simulation period is immediately reclaimed.

11.  Pulse footprint reclamation metrics

- For each footprint type, enter the proportion (0 - 1) of the footprint exposed to pulse reclamation.
- For each footprint type, enter the interval (years) of pulse reclamation.
- For each footprint type, enter the initial year in which pulse reclamation occurs.
