dc.descriptionData were collected in the field with high-resolution imagery loaded on computer tablets. Points were classified based on their dominant vegetation in three main categories: tamarisk, Russian olive, or absence. Dominance was defined as occupying greater than 50% of the canopy within a roughly 7 m radius circle. Collected information classified the status of tamarisk as either live, dead, a mixture of live and dead or having red foliage from tamarisk beetle attack (called "red phase tamarisk" in the data). Further, absence points were classified to indicate the dominant vegetation or land cover (i.e., water, bare ground, etc.) at that location.
dc.descriptionThe tamarisk & Russian olive data is mainly collected in Colorado, Utah and Arizona. Sampling is done opportunistically as land ownership, access, and logistics allow.
