Insect herbivore impact on a keystone plant colonist in primary succession at Mount St. Helens from 1994 to 2017

This data base contains estimates of damage to lupin (Lupinus lepidus
var. lobbii) by several species of leaf-tying and root-boring moth
larvae (Lepidoptera), along with associated estimates of vegetation
cover, in primary successional sites at Mount St. Helens. The surveys
began in 1993 and are ongoing; This database includes data for 1994,
1995, and 1998-2017. Surveys were located at a variety of primary
successional sites on Mount St. Helens’ Pumice Plain. Surveys
generally occurred in mid to late August, when leaf-miner damage is at
its maximum, but prior to maximum damage by root-borers. The number of
sites, location of sites, and types of data collected varied across
years and, but lupin cover, bare ground, and % lupin damage are
reliable across the time series. Please note, leaf-miner damage has been been temporarily deleted from
lupin.csv. Contact data authors if you seek a collaboration using the
deleted data.
