CALMIT research Ecosystem health & biodiversity
CALMIT deploys a combination of imaging spectrometry, imaging fluorometry, and thermal imaging to monitor photosynthesis, ecosystem health, vegetation stress, and biodiversity. The video below illustrates how remote sensing is being used to assess these topics – both elsewhere and at UNL.
Can remote sensing assess species richness?
Yes, remote sensing can assess biodiversity through optical diversity.
Why does quantifying species richness and biodiversity matter?
Species richness generally promotes ecosystem productivity and resilience.
Remote sensing offers new, objective ways of assessing productivity and biodiversity.
CALMIT researchers study new ways of understanding vegetation productivity and diversity using remote sensing, allowing us to evaluate ecosystem health over large areas.
