# Title of Dataset: Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna --- Opuntia spp. cactus densites in herbivore exclosure treatments. See Wells et al. (2022) for detailed methodology. ## Description of the Data and file structure These data can be used to compare Opuntia spp. cactus densities among the experimental treatments. Definitions: KLEE = Kenya Long-term Exclosure Experiment UHURU = Ungulate Herbivory Under Rainfall Uncertainty GLADE = Glade Legacies And Defaunation Experiment. 'all wild ungulates' = from megaherbivores (>1,000 kg; elephant & giraffe) to dik-dik (~5 kg). Variables & allowable values: File: 'OpuntiaSpp_Densities.csv' 'Experiment': (1) 'KLEE', (2) 'UHURU', (3) 'GLADE' 'Treatment': (1) 'Unfenced', (2) 'Excludes mammalian herbivores >120cm', (3) 'Excludes megaherbivores', (4) 'Excludes all wild ungulates'. 'Block': replicate (1-3 for KLEE & UHURU; 1-4 for GLADE) 'vol': cactus volume (cm3) = pi * height * (width/2) * (depth/2). 'volDens': cactus volume divided by sampled area (cm3/ha). 'logVolDens': log-transformed cactus volume density. 'count': number of Opuntia spp. plants. File: 'UHURU_timeseries.csv' 'Year': 2009-2021. 'Block': 1-3. 'Treatment': (1) 'OPEN' (=Unfenced), (2) 'MEGA' (=Excludes megaherbivores), (3) 'MESO' (=Excludes mammalian herbivores >120cm), (4) 'TOTAL' (Excludes all wild ungulates). 'Count': number of Opuntia spp. plants. ## Sharing/access Information Links to other publicly accessible locations of the data: NA Was data derived from another source? If yes, list source(s): NA
