About this calculator
This calculator determines the minimum recommended width for ecological corridors, essential for connecting habitat fragments and enabling gene flow between populations. The value is based on a base width of 100 meters, plus an additional 50 meters for each kilometer of corridor length.
The formula reflects ecological principles: longer corridors need to be wider to compensate for increased edge effects and ensure safe movement of species. The base width of 100 meters is a commonly cited minimum in literature for many vertebrate species.
Use this tool in conservation projects such as management plans of protected areas, environmental impact studies, and rural landscape planning. It helps in initial dimensioning, but should be complemented with local analyses of biome, target species, and matrix permeability.
Caution: the formula is generic and does not replace specific studies. Consider vegetation type, presence of barriers (roads, rivers), and species behavior. In open biomes or highly degraded fragments, different values may be more suitable.
Frequently asked questions
What does the base width of 100 meters mean?
The base width of 100 meters is a minimum value often cited in ecological literature to allow movement of many animal species and reduce edge effects.
How do I measure the corridor length?
The corridor length is the linear distance between the two fragments it connects, measured in kilometers. It can be obtained from satellite images, GPS, or maps.
Does this formula work for all biomes?
No. The formula is generic and developed for tropical forests. In open biomes such as savannas, the minimum width may differ due to vegetation structure.
Can I use this calculator for urban corridors?
It is not recommended. Urban corridors have different dynamics with barriers like roads and buildings, requiring specific permeability and safety analyses.
Is the additional width of 50 m/km always necessary?
Yes, for long corridors it is important to maintain functionality, as the chance of external interference increases with distance.
