Koford 323 Cynomys ludovicianus December 15, 1955 CPER, NW Weld Co., Colorado. sealed much eating of Opuntia. Some clumps had 4 or 5 leaves about half consumed (out of 20+ stems), + some leaves free & cut off. This fresh works on succulent stems. Within 50' of currently used mound every clump coter had fresh chewings. Rabbite may do some of this. Some fresh repair mounds - scratching & butting - utilizing moisture of melted snow & ground.
