Pearson - 1994 20 Bamboo October 29- For LiaoLiao marked culms see Journal. October 30- La Veranada. The clump back in the woods (E2) had 17 dead shoots. 14 of them had clear sign of being killed by insects, in 3 of them I could find no clear sign of such. There were 20 living yearlings; marked the with pen. Clump E3 had 29 dead shoots. 24 of them clearly killed by insects; 5 not sure. 7 live yearlings; marked them with pen. October 31- Visited Pampa Quemada where the fire had swept through the scrub a year ago (October 14). Woodcutters have removed a lot of firewood such as retamo, radial and nire and made piles of branches. The only trees alive and standing were a few mayten. There were quite a few regenerating bamboo clumps, which we did not detect last year. They were usually mixed in with trunks of retamo or radial or nire, or all three. All three are root-sprontg vigorously, hardly any standing ones survived. Rosa mosqueta was killed back but has recovered with stems 4 or 5 feet long. All the standing canes of the bamboo had been killed by the fire, but not consumed. These dead canes are now emerging from a tangle of short bushy bamboo culms, many of them grazed by cows (and horses?). Lots of tuco diggings, especially at the base of the dead clumps of whatever species. The short bushy culms are 2 or 3 feet tall, and may have 25 nodes. We saw only a couple of yearling culms 4 or 5 feet tall and without leaves. Why not more? There obviously was a lot of culm production, by why no production of tall yearlings, which must have been ready to go at the time of the fire. Perhaps they got killed by the fire while they were still small shoots or even rhizome buds? Then the rhizome produced a frenzy of small shoots? The only proper yearlings that we saw were produced by clumps at the edge of the fire zone that had not been burned. Some Berberis (calafate) survived. November 1- Cerro Otto. Clump A1 out in the open had no dead shoots, 15 yearlings, and one skinny yearling a little over 1m tall with a dead tip but no insect signs.
