Habitat characterization
Habitat characterization provides information on the environmental factors that are conditioning the presence of target CWR populations and help to define the CWR niche.
Bear in mind that...
Environmental factors are largely responsible for the different types of evolutonary adaptations that the populations may have experienced and that could potentially be transferred to the related crops.
How do I characterize the habitat?
Describe the habitat type where the genetic reserve is located. The description should include the abiotic physical characteristics, such as topography, geology, soil and climate, and the biotic component, including co-occurring plant species, pollinators, herbivores, seed dispersers, pests and diseases.
In Europe, follow the standardized EUNIS habitat classification developed by the European Environment Agency (EEA) to describe the habitat type. In case of Natura 2000 sites the description should be directly linked to the list of Habitats Directive Annex I ‘natural habitat types’ with clear distinction of priority habitat types (listed in Natura 2000 standard data forms and existing management plans) (European Council, 1992; European Commission, 2013). Refer also to their conservation status and results of habitat assessments. Additional information on vegetation types according to regional approaches would also be very useful (e.g. Braun-Blanquet plant communities). Focus the description on the habitats that are hosting the most important CWR populations within the site. Include as well some information about the most important ecological processes that might affect the effective protection of CWR, such as secondary succession, change in species composition or results of change in water regime, including human intervention, such as changes in land use.
