Methods: Circular plots (250m2) are established based on the impact types from the volcano blast arrayed along transects. Additional transects are established from the center pole of the circular plot at 90o angles. Individuals were identified within quadrats placed along these secondary transects.

Data Collected: species, richness, plot cover, diversity, evenness, mean species frequency

Wisconsin prairie restoration data

I havent looked closely at what’s sepcifcally available, but this could be a cool dataset to explore.

LTER sites

There are lots of different options in the LTER network. I highlight a few, but don’t be limited to considering just these sites. There are some really interesting datasets you could choose.

The following table show the general variables common across LTER sites. There are lots of specific datasets nested within these.

variable	description
title	title of project
proj_metadata_key	unique project id
lterid	lter name
datatype	type of abundance data (e.g. count,biomass)
structured_data	are abundance observations grouped (e.g. based on age)?
studytype	experimental or observational study?
duration_years	duration of project in years
community	does data set contain multiple taxa?
structure	types of indidivual structure
treatment	types of treatment
lat_lter	lter site latitude
lng_lter	lter site longitude
species	specific epithet of a taxonomic unit
kingdom	kingdom
