The Unexpected and Thrilling life of Grass - A Statistical Story


I'm an aspiring Environmental Scientist and i've recently finished some data collection to do with Common Grassland Species. My hope was to match my findings against a Botany report done several years ago to see the change over time. However i can't figure out which tests to use as most instructional Stats videos give examples of situations that seem incomparably different.

My Data is generally speaking a long list of about 60 species names next to their mean coverage of a meter square. And an almost identical table taken from the Botany report, that has fewer species present, and better coverage given to different species then i found in my later survey.

What can i or should i do with this data?

Thanks for your time, helpful answers could help adorable grassland critters.
