LARCH - sustainability of ecological networks
LARCH is an ecological model to assess the sustainability of species. High quality and well connected ecological networks are the basis for the conservation of species living in fragmented habitats. LARCH assess the suitability for local populations by using species-specific area requirements.
LARCH uses specie specific metrics to assess the connectivity between fragmented or dispersed habitat areas. These metrics help to evaluate the overall cohesion of ecological networks, providing insights into the strength of the connections and sustainability of the habitats. Within the analysis it is possible to consider the impact of barriers (such as roads or rivers) blocking the dispersal of individuals as well as landscape features that increase resistance (like agricultural areas that are difficult to cross).
Here's what LARCH does in simple terms:
Assesses habitat viability:
- Determines if an area can support sustainable populations of specific species;
- Uses information about habitat needs, movement abilities, and space requirements of different animals.
Analyzes landscape connectivity:
- Evaluates how well-connected different fragmented habitats are for species;
- Identifies potential wildlife corridors and bottlenecks in the landscape.
Simulates different scenarios:
- Helps planners understand how changes in the landscape might affect various animal species;
- Can show the impact of barriers like roads on animals' ability to move through an area.
Supports decision-making:
- How big should a nature reserve be for certain species?
- Which areas are most important for preserving specific types of wildlife?
What landscape layout works best for different groups of animals?
By combining these functions, LARCH provides valuable insights for land use planning, conservation efforts, and ecosystem management. It helps researchers and planners make informed decisions about how to design and manage landscapes to support biodiversity and wildlife populations.
