Abstract: 

Sum of dry mass removed for each plant growth form from each plot of biodiversity experiment. Amount of plant material removed in initial establishment of plant diversity treatments was recorded for later use as covariate or measure of disturbance.

Material was weighed in the field by species, and species-level data are available from Huenneke; however, this file summarizes plant material removed (dry mass) by growth form (shrub, subshrub, perennial grass, succulent) and by total live dry mass. Also provided are mass of dead material collected from plots (same species as live material removed for each treatment) and total dry mass, live plus dead.

Abstract: 

Twenty 6 x 6 m plots were established with a 3 m buffer between plots. Five plots were randomly assigned to one of four treatments: (1) chlordane amendment 100ml AI (active ingredients) per 10,000 ml) to exclude microarthropods, (2) sprinkler irrigation (6 mm per week), (3) sprinkler irrigation (6 mm/week) plus chlordate amendment (as above), (4) control (no treatment).

Measurements are taken on Erioneuron pulchellum at monthly intervals. Three randomly located subsamples are collected from each plot. Data set contains plant diameters, mites soil weight, root weight, nematode soil weight, root total nitrogen, and nematode number.
