Projekt im Biesenthaler Becken

The next report. Sadly, a high mortality amongst the Eichen since May 2010, but still a good strike rate for the Buchen. The gates are in good condition too. No real need either to cut back grass from around the saplings. Someone (BUND perhaps) has also hung a large number of Nistkasten on the trees surrounding the planting sites. Finally, Berit and I had a good view of a Wendehals (Eurasian wryneck), on Brandenburg red list but otherwise not threatened, while walking to the planting area from Bahnhof Rüdnitz. – Robbie Morrison

Details

plot #6

fence in good condition
mostly Buchen, good strike rate

plot #7

fence in good condition
dry plot with Brennnesseln, but not sufficiently dense to affect saplings
good strike rate, some saplings now 2m in height

plot #8

fence in good condition
around 20% mortality

plot #9

we failed to find plot #9 this time!

plot #10

fence in good condition
around 80% mortality rate for Eichen, some near dead saplings have new leaves at the bottom
the Buchen are mostly okay

plot #11

fence in good condition
a few Eichen doing well, but powdery mildew also present
the Buchen are mostly okay

The sick and dead Eichen in plot #10 look like their bark was attacked, either by a disease or by insects. Some of the bark has peeled back to reveal damage from boring insects which leave small neat holes. But no sign of animal grazing, say by mice in winter. Note the earlier comment that some near dead saplings have new leaves as the bottom of their stems only.

Berit Erlach and I helped plant some trees on this site on 07-Nov-2009. We revisited the site on 23-May-2010. Almost all trees look healthy. The gates are in good condition. Except for perhaps one plot (#11), no further work is currently necessary. - Robbie Morrison

Details

plot #6

fence in good condition
no dead trees visible (but this is a large plot)
some competition from weeds, but not worth cutting back

plot #7

fence in good condition
no dead trees visible
some competition from nettles and weeds, but not worth cutting back

plot #8

fence in good condition
several dead trees visible, but these could be from the original planting
no significant competition from weeds

plot #9

fence in good condition
no dead trees visible
some competition from weeds, but not worth cutting back

plot #10

fence in good condition
1 dead tree (from about 100)
no completion from grass, bark chips are working well

plot #11

fence in good condition
2 dead trees (from about 100)
competition from ragwort (Senecio sp), should ideally be cut back

500 Buchen und 200 Eichen nachgepflanzt, Gatter repariert, teilweise mit Robinienrinde gemulcht. Siehe Projektseite Nachpflanzen im Biesenthaler Becken

In den vorherigen Monaten war es sehr trocken, gleichzeitig haben wir erfahren, dass einige Lärchen umgefallen sind. Unser Förster hat uns jedoch zugesichert, dass in den nächsten Tagen die Gatter repariert werden.

Hier eine erste Einschätzung: Ein Gatter wurde sehr stark zerstört, jedoch kein Wildverbiss. Alle anderen Gatter sind in einem guten Zustand. Mehr als 2/3 der Buchen ist vertrocknet, viele offenbar erst vor kurzem.

Wir überlegen, ob wir nachpflanzen und/ oder Bucheckern und Eicheln in den Gattern verteilen…

Noch geschlossen, der größte Teil der Buchen ist vertrocknet.
