New plants found in Split Oak Forest from the BioBlitz through July 2018

I’ve been inspired by our hiking group1 finding a new plant species to look at how many new plant and animal species we have documented in Split Oak since the BioBlitz on May 4-6, 2018.

This summer-blooming wildflower in the Aster family was not vouchered2 in Osceola County and it had not been recorded in iNaturalist3, by FWC4 or in a herbarium5 as being present in Split Oak Forest.

BioBlitz

Danny Goodding, a PhD candidate at the University of Central Florida, planned and ran the entire event. Scheduling it in May meant that we could perhaps observe Spring wildflowers that were not observed by the FWC contractor that created the plant list, as they did their survey in the fall.

BioBlitz participants observed 303 species in Split Oak Forest, compared to the 400 species listed in the previously referenced FWC management plan.

The species count for Split Oak Forest on iNaturalist is currently at 548, only two months after the BioBlitz!

Including the species found during the BioBlitz, people visiting Split Oak Forest between May 4 and July 16, 2018 documented 88 new species, including 4 new endemic plant species, 44 new common plant species, 5 new species of animals, 34 new species of insect, and 2 new species of fungi/lichen
