2. Background:
- Higher N:P in bark predisposes beech to
fungal lesion development. (Cale et al. 2015)
- X. betulae might also be a causal agent in
the BBD disease complex.
Bartlett mid (C6) and old age (C7, C8)
stands:
- 5 beech trees per plot
- 8 frames painted per tree, for long-
term photographing and monitoring
- Fungal sample collection
Questions:
Is severity of BBD correlated with N:P
balance? And/or N/P treatment?
Correlation of bugs and fun-guys with
treatment?
Remaining work:
- Image analysis
- Fungal
identification
- Culturing
Neonectria
