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.
