Park biologist Ramona Viterbi (GPNP) said: “Remote sensing observations provide coherent information on the state of the environment in the Gran Paradiso National Park, including snow cover, surface temperature, biological variables (GPP and others). RS observations also allow for upscaling of in-situ measurements, such as those provided by the field stations measuring carbon and water fluxes in the soil-vegetation-atmosphere system and providing information on the health state of Alpine grassland. In addition, remote sensing products directly supported the monitoring of fauna and habitat, providing frequent and detailed surveys that are useful for park management. Indirectly, RS products could be used to estimate the relationships between fauna and habitat, such as, for example, the link of the changes in phenology with herbivore population dynamics.” |
